DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 TUESDAY *** Marginal Smoke Dispersal Conditions *** A strong high pressure area will be centered over Las Vegas, Nevada on Tuesday while a major trough develops about 1000 miles to the west in the Gulf of Alaska and eastern Pacific Ocean. Upper flow over the area will be west-southwest with very stable conditions developing. Expect dry weather and partly cloudy skies. Mixing heights will be suppressed and transport winds will be mostly light and variable. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) *** Marginal or Occasionally Poor Ventilation Conditions Through the Week *** By Wednesday the upper high looses strength and drifts east. Flow aloft backs to southwest. Transport winds switch to southeast through east most areas. Maximum mixing heights remain low and nighttime inversions will hold any residual smoke close to the ground. The upper ridge re-strengthens on Thursday for continued low maximum mixing heights and unfavorable ventilation conditions. An upper disturbance moving through on Friday will lift maximum mixing heights to more favorable levels. 2.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 WEDNESDAY *** Marginal Smoke Dispersal Conditions *** Upper air charts show a broad ridge with its axis stretching from Arizona northward to Alberta and a broad trough in the Gulf of Alaska and the eastern Pacific about 900 miles west of the coast. Upper flow over Oregon is southwesterly. Temperatures aloft will be much warmer than average for this time of year. The warm air aloft will make the atmosphere very stable for unfavorable smoke dispersal conditions. Transport winds will be generally from southeast and light, while mixing heights will be quite low. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) *** Marginal Ventilation Continues Thursday *** The upper level pattern slowly shifts east with little improvement for Thursday. By Friday the upper trough approaches from the west and temperatures aloft will be much cooler helping to improve ventilation.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 FRIDAY The massive upper-level ridge of high pressure that has been bringing unseasonably warm temperatures and stagnant ventilation conditions will weaken and shift slightly eastward. The ridge axis is forecast to stretch from Utah through eastern Montana with a slowly strengthening southwesterly flow aloft over Oregon. The first in a series of progressively stronger weather systems will fall apart along the coastline, with just a few clouds will drifting over the region. Warm air aloft will continue to suppress mixing heights and locally get mixed to the surface by increasing southerly winds. That could result in near-record warm surface temperatures. Smoke dispersal conditions will be mostly marginal. OUTLOOK (SATURDAY-MONDAY) The second in a series of weather systems will approach the coastline on Saturday, but it appears as if any significant rainfall will stay offshore until evening. Clouds will be on the increase over NE Oregon with only a slight chance of light showers. Southerly winds will keep surface temperatures well above normal. However, cooling aloft will raise afternoon mixing heights and improve ventilation conditions. A cold front will likely spread rain across western Oregon by Saturday night and into NE Oregon Sunday morning, with rain continuing through the day. Rainfall amounts should exceed one-quarter of an inch, with up to three-quarters of an inch possible at higher elevations. Surface temperatures will cool to near normal. Cooler air aloft will drop the snow level to around 4500 feet, by evening, with good afternoon smoke dispersal conditions. Showers will continue through Sunday night. A flat and transitory upper-level ridge will being some drying on Monday and may suppress afternoon mixing heights slightly. Surface temperatures will cool to slightly below normal with a continued threat of showers, mainly in the morning. Transport winds will remain onshore with fair to good smoke dispersal conditions. 2. DISPERSION FRIDAY Mixing height below 500 ft early rising to 1200 - 2200 ft by late morning. Afternoon mixing height rises to 2200 - 3200 ft then lowers below 1000 ft during the evening.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 SATURDAY The massive upper-level ridge of high pressure responsible for the recent spell of dry, warm and stagnant conditions will continue to weaken and shift eastward. The ridge axis is forecast to stretch from New Mexico to North Dakota with strengthening southwesterly flow aloft over Oregon. The second in a series of weather systems will approach the coastline on Saturday, but it appears as if any significant rainfall will stay offshore until evening. Clouds will be on the increase over NE Oregon with only a slight chance of light showers. Southerly winds will keep surface temperatures well above normal. However, cooling aloft will raise afternoon mixing heights and improve ventilation conditions. OUTLOOK (SUNDAY-TUESDAY) A cold front will likely spread rain across NE Oregon late Sunday morning, with rain continuing through the afternoon. Rainfall amounts should exceed one-quarter of an inch, with up to three-quarters of an inch possible at higher elevations. Surface temperatures will cool to near normal with good afternoon smoke dispersal conditions. Cooler air aloft will drop the snow level to around 4500 feet by evening. Showers will taper off Monday with a flat and transitory upper-level ridge turning the flow aloft west-northwesterly. Surface temperatures will cool to slightly below normal with snow levels dropping to near 3500 feet. Transport winds will turn mostly westerly with fair to good smoke dispersal conditions. The next weather system is forecast to move mainly into northern California and southern Oregon on Tuesday. That would keep snow levels around 3500 feet north to 4000 feet south, but precipitation will be limited. Transport winds will depend on the exact track of the low-pressure center but appear as if they may turn southerly. Smoke dispersal conditions should remain fair to good. 2.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 SUNDAY A cold front will likely spread rain across the region in the morning, with rain turning to showers by late afternoon. Rainfall amounts should exceed one-quarter of an inch, for most areas, with up to three-quarters of an inch possible at higher elevations. High temperatures will dramatically cool, back to near normal, with good afternoon smoke dispersal conditions. Cooler air aloft will drop the snow level to around 4500 feet after dark. OUTLOOK (MONDAY-WEDNESDAY) Showers will continue Monday, mainly over the mountains, with a drier northwesterly flow aloft bringing some clearing late in the day. Highs will be 5-10 degrees below normal with snow levels dropping to near 3500 feet. Transport winds will turn mostly westerly with good smoke dispersal conditions. Partial clearing is likely Tuesday, with the next weather system not coming onshore until Tuesday afternoon. Smoke dispersion should be fair to good with mostly southerly transport winds. Previous computer model forecasts showed this next system headed mainly into southern Oregon and northern California, but now guidance aims it more directly at Oregon. That will bring rain and snow back into NE Oregon by Tuesday night with snow levels near 4000 feet. Rain and snow showers will taper off Wednesday, as the weather system pushes into the Rockies.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 MONDAY Upper troughiness over the Pacific Northwest will be moving east during the day and a broad, flat ridge will be approaching from the west. This will slowly stabilize the atmosphere but scattered showers will likely persist into the afternoon. Expect fair to good smoke dispersal conditions most areas. EXTENDED OUTLOOK (TUESDAY - THURSDAY) *** Slowly Deteriorating Smoke Dispersal Conditions after Tuesday *** An upper low moves rapidly across the eastern Pacific during the day on Tuesday. A surface cold front associated with this low will bring rain back to the region. Rain will reach the region by evening but amounts will be light. The front and upper low move rapidly through the region and by Wednesday a strong ridge pops up to the west. Subsidence with this ridge will depress maximum mixing heights. Smoke dispersal conditions drop to marginal. The upper ridge moves eastward across the region on Thursday further stabilizing the atmosphere. Expect smoke dispersal conditions to be generally poor. 2. DISPERSION MONDAY Zone 630 and 632: Mixing height 2600 - 3600 ft during the morning.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 TUESDAY A small, fast moving upper low moves across the southern Gulf of Alaska and into the Pacific Northwest on Tuesday. The low supports a Pacific cold front which will bring rain to the region much of the day. Rain spreads east during the late morning or early afternoon. Amounts should be one-third of an inch or less and the snow level should be around 4000 feet. EXTENDED OUTLOOK (WEDNESDAY - THURSDAY) *** Marginal Ventilation Conditions Wednesday *** The upper low moves rapidly east and the atmosphere becomes increasingly stable as an upper ridge builds over the eastern Pacific. Light and variable winds, together with low mixing heights by afternoon will lead to marginal smoke dispersal conditions for Tuesday. The upper ridge axis moves over the Pacific Northwest on Wednesday night and by Thursday an upper disturbance moves across the eastern Pacific and into northwest Washington and southern British Columbia. The strength and exact track of this disturbance are difficult to assess at this point. If it should stay farther north than forecast then the mixing heights shown below are too optimistic. For now I will go with significant improvement and better burning conditions for Thursday. On Friday a broad flat ridge has set up over the Pacific Northwest. Expect little change in maximum mixing heights and a generally west to northwest transport wind. 2. DISPERSION TUESDAY Zone 630 and 632: Transport wind S to SSW at 20 - 36 mph during the morning.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 THURSDAY A transitory upper-level ridge of high pressure will slide over the region, around midday, and then advance eastward into Idaho. That will bring a dry day with at least partly sunny skies. A weak cold front will move onshore in the late afternoon and evening. Ahead of the front, southerly transport winds will increase in the afternoon. Warming aloft will suppress mixing heights with only marginal smoke dispersal conditions. OUTLOOK (FRIDAY-SUNDAY) A weak cold front will bring a chance of light showers Thursday night through Friday morning, with snow levels near 4000 feet. Rainfall totals should be around one-tenth of an inch or less, with an inch or two of snow at the higher elevations. A flat upper-level ridge, in the eastern Gulf of Alaska, will bring a drying and cool northwesterly flow aloft to the region Friday afternoon. Transport winds will turn more westerly with improved mixing yielding fair smoke dispersal conditions. A stabilizing air mass will quickly drop mixing heights in the evening. A broad upper-level ridge will continue to amplify offshore, Saturday and Sunday, with a strong north-northwesterly flow aloft over Oregon. Skies should stay mostly cloudy with a chance of light rain or snow showers. The snow level will slowly rise to above 5000 feet.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 SATURDAY A broad upper-level ridge will continue to amplify offshore. A warm front will track along a strong jet stream, on the north side of the ridge, and drop into the Pacific Northwest. Skies should become mostly cloudy with a chance of light rain by the afternoon. Rainfall totals should be less than one-tenth of an inch. The snow level will slowly rise to above 5000 feet. Warming aloft will suppress mixing heights with marginal to poor smoke dispersal conditions. OUTLOOK (SUNDAY-TUESDAY) The warm front is forecast to dissipate over Oregon on Sunday, as the offshore upper-level ridge continues to build. The flow aloft will turn from northwesterly to more northerly and begin to dry out. Skies should remain mostly cloudy with a chance of light rain. The snow level will rise to near 7,000 feet. Warm air aloft will keep mixing heights suppressed with continued marginal to poor smoke dispersion. The offshore ridge will begin to flatten on Monday, allowing a weak weather system to slide down the southern British Columbia coastline. That will maintain considerable clouds and a slight chance of showers, with the snow level staying near 7000 feet. Ventilation conditions should improve to marginal to fair. Strong northwesterly flow aloft is forecast for Tuesday with a weak and transitory ridge limiting shower activity. Skies will be partly cloudy with snow levels dropping to around 5000 feet. Smoke dispersal conditions should improve to fair to good. 2. DISPERSION SATURDAY Mixing height below 500 ft early rising to 1000 - 1600 ft by late morning.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 MONDAY Upper air charts show a high pressure area centered about 600 miles west of San Francisco and an upper level disturbance moving across the top of the high into British Columbia. This helps maintain a weak warm front that moves over the Pacific Northwest. Upper level winds will be northwesterly. Warmer air aloft with the warm front will stabilize the atmosphere for reduced maximum mixing heights. Look for marginal smoke dispersal conditions. EXTENDED OUTLOOK (TUESDAY - THURSDAY) The upper disturbance moves British Columbia and northern Washington early Tuesday - cooler temperatures aloft behind this system will allow for higher maximum mixing heights and improved ventilation conditions. Transport winds will be generally west southwest to west northwest. By Wednesday a deep low in the Gulf of Alaska, both at the surface and aloft, begins to influence weather in the Pacific Northwest. Winds turn southerly both at the surface and aloft. A surface cold front moves into western Washington then drops south into northwest Oregon by afternoon but rain will hold off until Thursday. Expect south-southwesterly transport winds Wednesday, becoming light on Thursday but still favoring southwesterly. 2. DISPERSION MONDAY Zone 630 and 632: Maximum mixing height 2500 feet.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 FRIDAY The axis of a cold upper-level trough will remain just offshore with a moist and very strong west-southwesterly flow aloft over Oregon. Impulses dropping southward into the trough will act to maintain a weak surface low-pressure area off the Washington coast. Circulation around that system will feed ample moisture onshore for scattered rain and snow showers. Cold air aloft will keep the snow level in the 2500-3000 foot range. Expect good smoke dispersal conditions with south to southwesterly transport winds. OUTLOOK (SATURDAY-MONDAY) A fairly strong upper-air disturbance will deepen the offshore trough, with both a surface and upper-air circulation center forecast to strengthen and drift southward, to just off the southern Oregon coast, by Saturday evening. That will weaken the onshore transport winds and taper off the shower activity. Snow levels will slowly drop to between 2000 and 3000 feet. Vertical mixing will remain good, but transport winds will locally become light and variable. On Sunday, the offshore trough will get forced inland, across northern California, with some rain and snow showers possibly circulating as far north as the extreme southern districts. Meanwhile, a mostly dry northwesterly flow aloft will bring partial clearing to most areas along with colder temperatures. Snow levels will drop to near 2000 feet. Smoke dispersal conditions will be fair to good with increasing northwesterly transport winds. By Monday, the flow aloft is forecast to turn northwesterly, in response to a cold upper-level system dropping southward from British Columbia. The track of this system is still uncertain, but it should bring at least some snow showers to most areas. It appears likely that it will usher the coldest air of the season into the region. Snow levels will drop to near valley floors in all zones. Smoke dispersal conditions should remain fair to good with mostly north to northwesterly transport winds. 2. DISPERSION FRIDAY Mixing height below 2000 ft early rising to 3000 - 4000 ft by late morning. Afternoon mixing height rises above 5000 ft then lowers to 1800 - 2800 ft during the evening.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 SATURDAY A cold upper-level trough will remain anchored over the region with the trough axis staying just offshore. A fairly strong upper-air disturbance will drop southward, into the parent trough, with a corresponding surface low-pressure center developing off the Washington coast and drifting southeastward during the day. Southerly transport winds will weaken with continued scattered rain and snow showers. Snow levels will drop to between 2000 and 2500 feet. Vertical mixing will remain good, but transport winds will locally become light and variable. OUTLOOK (SUNDAY-TUESDAY) A cold upper-level trough will remain over the region, on Sunday. One disturbance will rotate inland early, across southern Oregon, and may circulate a few snow showers northward over mainly the southern zones. The northern zones will come under the influence of an even colder northwesterly flow aloft. Smoke dispersal conditions will be fair to good with increasing north to northwest transport winds. Another upper-level disturbance is forecast to drop southward, from British Columbia, to just off the Washington and northern Oregon coast, late in the day. That system appears to have enough moisture to bring an increasing chance of snow to all zones, late Sunday, with snow levels dropping to near the valley floors. By Monday, the flow aloft is forecast to turn northwesterly, with an even colder upper-level system dropping southward, from British Columbia, into the region. This system will be accompanied by a surface Arctic cold front, which will usher the coldest air of the season into the region. The track of this system is still uncertain, but it will likely bring accumulating snow to the entire region with the snow level on the valley floors. Smoke dispersal conditions should remain fair to good with mostly northwest transport winds. On Tuesday, a very cold and drier northerly flow is forecast, with sub-freezing temperatures and snow-covered ground likely. Skies will stay partly to mostly cloudy with a chance of light snow showers. Cold low-level air will stabilize the air mass, with light winds and only marginal smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 SUNDAY A cold upper-level trough will remain over the region. One disturbance will rotate across southern Oregon early in the day and will likely circulate some snow showers northward over most zones. The northern zones will come under the influence of an even colder northwesterly flow aloft. Smoke dispersal conditions will be fair to good with increasing northwesterly transport winds. Another upper-level disturbance is forecast to drop southward, to just off the Washington and northern Oregon coast, late in the day. That should spread snow across the region, Sunday night, with snow levels dropping to near the valley floors. OUTLOOK (MONDAY-WEDNESDAY) On Monday, an even colder upper-level system will drop southward and maintain areas of snow across the region. This system will be accompanied by a surface Arctic cold front, which will enhance the snowfall and then usher in the coldest air of the season. Accumulating snow is likely across the entire region with the snow level on the valley floors. Smoke dispersal conditions should remain fair to good with northwesterly transport winds. On Tuesday, a very cold and drier northerly flow is forecast, with sub-freezing temperatures and snow-covered ground likely. Skies will slowly clear with a chance of light snow showers. Cold low-level air will stabilize the air mass, with only marginal to fair smoke dispersal conditions and decreasing northwesterly transport winds. Computer models show an upper-level ridge building over the region by Wednesday with a dry and much more stable northerly flow aloft. That will lead to very cold temperatures and surface-based inversions. A weak impulse in the northerly flow is forecast to bring some middle and high clouds to the region in the afternoon but will not likely be strong enough to produce any precipitation. Smoke dispersal conditions will deteriorate to poor. 2. DISPERSION SUNDAY Zone 630 and 632: Mixing height below 1500 ft early rising to 2500 - 3500 ft by late morning.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 MONDAY A cold weather pattern has set up for the Pacific Northwest. In the upper atmosphere a strong ridge of high pressure has developed up in the eastern Pacific and the Gulf of Alaska with a cold trough extending from north-central Canada into southern California. This leaves the Pacific Northwest in a cold northerly flow aloft. There will be enough moisture for snow. Lower elevations will see 2 to 5 inches by Monday evening, higher elevations generally 5-8. Smoke dispersal conditions will be generally good with most areas seeing a westerly then southwesterly transport wind. EXTENDED OUTLOOK (TUESDAY - THURSDAY) The upper disturbance that moves through Monday afternoon and evening will bring another round of snow to the area. The snow will be tapering off on Tuesday as a drier flow moves over the region. Smoke dispersal conditions will be fair to good. For Wednesday and Thursday, the cold upper trough will move east and the ridge in the Pacific will begin to move over the area. Upper flow will be northerly and dry for mostly sunny weather. Temperatures, however, will remain cool. Cold nighttime temperatures will promote overnight inversions that will be slow to break and limit maximum mixing heights. Thus smoke dispersal conditions will be marginal Wednesday and beyond. 2. DISPERSION MONDAY Zone 630 and 632: Mixing height above 5000 ft throughout the day. Transport wind WSW to W at 19 - 33 mph during the morning and afternoon. Transport wind decreases to SW to W at 16 - 30 mph during the evening. Surface wind WSW to W at 12 - 22 mph throughout the day. Zone 633 - 638: Mixing height above 5000 ft throughout the day. Transport wind WSW to WNW at 15 - 29 mph during the morning and afternoon. Transport wind decreases to SW to WSW at 14 - 28 mph during the evening. Surface wind WSW to W at 12 - 22 mph.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 ------------------- Northeast ------------------------------------ TUESDAY An upper level trough, oriented NE to SW moves southeastward across the region on Tuesday. This supports a cold front - the leading edge of modified arctic air - as it also sweeps across the region Monday night and early Tuesday morning. This front will usher in cooler temperatures for mid week. Low elevation snow will fall as the front passes through, then drier air will filter southward to end any precipitation. Expect some sunshine and fair to good smoke dispersal conditions with a generally northwesterly transport flow. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) By Wednesday upper level flow is northerly, cold, and generally dry over the Pacific Northwest. Scattered snow showers are still possible, however. Subsidence aloft will suppress maximum mixing heights a bit, but smoke dispersal conditions should remain generally fair with a light southwesterly flow. An upper ridge axis passes through early Thursday and winds aloft back to more westerly, but maximum mixing heights are further suppressed resulting in poor smoke dispersal conditions. On Friday a strong westerly flow aloft over the eastern Pacific and the Pacific Northwest will push a Pacific cold front into northwestern Oregon early in the day. This will spread precipitation east of the Cascades during the afternoon and help push smoke dispersal conditions back into the fair category. 2. DISPERSION TUESDAY Zone 630 and 632: Mixing height 1700 - 2700 ft during the morning. Afternoon mixing height rises to 3500 - 4500 ft then lowers to 2000 - 3000 ft during the evening.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 Arctic air drove down from the north last night and early this morning and will set up shop for the next couple of days before gradually moderating. Air mass is moderately unstable today but as the surface temperatures cool tonight, strong temperature inversions will form and limit mixing overnight. As the upper ridge off the coast slowly moves in the air will slowly warm aloft. With chilly air near the surface, this will make for mostly poor mixing Wednesday. Wind flow will also be quite light under little pressure gradients. Thus smoke dispersion will be quite poor. OUTLOOK (THURSDAY - SATURDAY): A flattening upper level ridge builds in on Thanksgiving bringing warming temperatures aloft and near the surface. Another front will approach from the Pacific bringing increasing clouds overnight Thursday/Friday. Moisture will not likely begin until later Friday. Snow level will start out around 3000 - 4000 ft but lower to the surface in most locations on Saturday as the upper trough moves in. Air mass will remain stable through Friday before destabilizing on Saturday. Wind flow will increase from the S on Thursday, increase more on Friday, and then decrease and turn more SW to W on Saturday. Smoke dispersion will be poor Thursday, improving Friday, and good to excellent on Saturday. 2. DISPERSION WEDNESDAY Mixing height below 1000 ft early rising to 1000 - 1700 ft by late morning. Afternoon mixing height rises to 2000 - 3000 ft then lowers below 1000 ft during the evening. Transport wind WSW to WNW at 5 - 9 mph. Surface wind light and variable and controlled by local terrain.

If there are landowners thinking of burning over the holiday weekend, please call to coordinate by 4 p.m. this afternoon.**** 1. DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 Upper level ridge is building into the region today and will gradually moderate the arctic air that's been over the state since yesterday. Ridge will slowly flatten on Thanksgiving as the next frontal system approaches. Cloud cover today is mainly the result of a strong jet stream coming down from the north which is part of our current cold spell. Higher clouds should slowly dissipate overnight as the ridge moves inland. Air mass is stabilizing and may lead to some fog formation in the valleys tomorrow morning. With residual surface cold air and warming aloft, along with only light wind flow, expect very poor smoke dispersion. OUTLOOK (FRIDAY - SUNDAY): Forming upper level trough in the eastern Pacific will eject a front into the state on Friday, bringing increasing clouds Friday with a chance of moisture later in the day. The front will gradually scour the air shed Friday and into early Saturday. However, the air mass will not likely destabilize completely until Saturday afternoon when the upper level trough arrives. Snow level will rise to near 5000 ft Thursday night and Friday, then lower to near the surface on Saturday. Upper trough moves off to the east on Sunday with a minor ridge moving in during the evening. Air mass should remain mostly unstable on Sunday then stabilize Sunday evening. 2.

Maximum mixing heights should be quite high for fair to good smoke dispersal conditions. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) Upper flow over the region will be generally west-southwest through the outlook period. On Wednesday the atmosphere stabilizes for drier conditions. Maximum mixing heights are suppressed somewhat for mostly fair smoke dispersal conditions. Tuesday's front is reenergized a bit on Thursday and drifts northward for some periods of light rain, then moves east for dry weather again on Friday. Ventilation conditions will be generally fair Thursday and Friday. 2. DISPERSION TUESDAY Zone 630 and 632: Mixing height 3500 - 4500 ft during the morning.
