DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 WEDNESDAY An upper level low in the Gulf of Alaska gives west-southwesterly flow aloft over the region. Minor impulses traveling WSW to NNE in the flow keep scattered showers going through the day. Skies will be mostly cloudy and smoke dispersal conditions will be fair to good. OUTLOOK (THURSDAY-SATURDAY) The upper low moves slightly west Wednesday and upper flow over the area becomes slightly more southwest. A more significant impulse drives a Pacific front to the coast early on Wednesday. Rain will spread eastward during the morning and early afternoon. Smoke dispersal conditions will be fair to good. On Thursday the southwest flow aloft continues but the region will be between weather systems. Never the less there will still be enough moisture around for scattered showers. Slightly warmer surface temperatures should push afternoon mixing heights up a bit for generally good smoke dispersal conditions. A more significant spring storm will develop Friday as a surface low off the SW Oregon coast. This will track from SW to NE toward northwest Washington. Look for rain and brisk winds throughout the day. 2. DISPERSION TUESDAY Mixing height below 500 ft early rising to 2000 - 3000 ft by late morning. Afternoon mixing height rises to 4000 - 5000 ft then lowers to 1800 - 2800 ft during the evening. Transport wind SSW to SW at 9 - 15 mph during the morning. Transport wind shifts to WSW to WNW at 10 - 18 mph during the afternoon and evening. Surface wind SSW to SW at 8 - 12 mph during the morning. Surface wind shifts to WSW to WNW at 9 - 15 mph during the afternoon and evening. OUTLOOK: WEDNESDAY Mixing height below 1000 ft early rising to 2900 - 3900 ft by late morning rising to 3500 - 4500 ft during the afternoon. Transport wind SW to WSW at 20 - 36 mph.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 WEDNESDAY An upper level low remains in the Gulf of Alaska approximately 600 miles west of the Queen Charlotte Islands. Winds aloft over the Pacific Northwest will be from the west southwest and drive a Pacific weather front through the region during the day. Rain will spread into the region early and continue throughout the day. Warm air streaming northward in advance of the front will suppress mixing heights a bit for just fair smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) The upper low will be in about the same position on Thursday but the region will be between weather systems for mostly cloudy skies but only widely scattered showers. Cooler air aloft will push afternoon mixing heights well above 5000 feet for good smoke dispersal conditions. Another active Pacific weather system will move across the Northwest on Friday bringing clouds and significant rain to the area. The rain will taper off Friday night and by Saturday weak surface high pressure builds to the north for drying and warmer temperatures. Smoke dispersal conditions will be good to excellent Thursday and Friday, but light and variable winds will limit smoke movement on Saturday. 2. DISPERSION WEDNESDAY Mixing height above 5000 ft during the morning. Mixing height lowers to 4000 - 5000 ft during the afternoon and evening.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 THURSDAY An upper level low continues in the Gulf of Alaska producing a west-southwest flow over the Pacific Northwest. The flow is quite strong, especially for the time of year, with a 125mph plus jet stream cutting across the area at about 30,000 feet. However, during the day on Thursday the area will be between weather systems and while it will be generally dry I can't rule out a few widely scattered showers. Mixing heights will be high enough to provide good smoke dispersal conditions once morning inversions break. OUTLOOK (FRIDAY-SUNDAY) The heavy rain continues into Friday morning then slowly turns to showers and decreases. Mixing heights will provide fair to good smoke dispersal conditions. On Saturday surface high pressure begins to build but showers will continue, slowly decreasing during the day. At this point Sunday looks like a mostly dry day with partly cloudy skies. Mixing heights both Saturday and Sunday will be near or above 5000 feet for good smoke dispersal conditions. 2. DISPERSION THURSDAY Mixing height 3400 - 4400 ft during the morning.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 FRIDAY An unseasonably strong westerly jet stream will direct another potent Pacific storm across Oregon. Widespread morning rain will give way to showery conditions in the afternoon. A surface low-pressure system is forecast to track across extreme northwestern Oregon and western Washington in the early morning and then rapidly move into northeastern Washington in the afternoon. It is not forecast to be a real strong low-pressure system, but the forecast track is favorable to bring breezy southwesterly winds to the region in the afternoon. Clouds and rain will keep temperatures well below normal, but the snow level is expected to stay above 6000 feet. High mixing heights and strong transport winds will make for good smoke dispersal conditions. OUTLOOK (SATURDAY-MONDAY) Saturday will be a break between storms, but the strong westerly jet stream will direct a weaker weather system across mainly the northern half of the state Sunday. That will keep considerable clouds across the region with temperatures only recovering to near normal. Slightly warmer conditions are expected Monday. Daytime smoke dispersal conditions should be good during the period. The long-range computer models show more weather systems possibly sweeping across northern Oregon during the second half of next week. That would keep temperatures near to slightly below normal with an increasing chance of showers. 2. DISPERSION FRIDAY Mixing height above 5000 ft throughout the day. Mixing height lowers to 1500 - 2500 ft during the evening. Transport wind SSW to SW at 22 - 38 mph during the morning.

Expect increasing high clouds from a weak warm front moving south to north over the region. Transport winds will be generally southerly and mixing heights should be high enough to provide for good smoke dispersal conditions. OUTLOOK (WEDNESDAY-FRIDAY) By Wednesday the upper level low will be about 100 miles west of Grays Harbor, Washington. Upper level flow will be from the southwest with enough moisture for scattered showers. The upper low moves across northern Washington on Thursday with an upper trough sweeping across Oregon. This will keep showers going. By Friday the trough will be on an axis from northern Idaho to central Nevada and moving east. Flow aloft will be north or northeasterly. There will still be enough moisture for widely scattered showers. Maximum mixing heights should reach 5000 feet or above through the outlook period for good smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 FRIDAY The upper-level trough that brought cool and showery weather to the region Wednesday and Thursday will shift eastward and stretch from Montana to Nevada. Clearing skies will bring cold early morning temperatures with areas of frost. A fairly weak upper-level ridge will build just offshore with the flow aloft drying and turning northerly. Transport winds will turn north to northeasterly with some sunshine helping afternoon temperatures recover to within 5-10 degrees of normal. High afternoon mixing heights should make for good daytime smoke dispersal conditions. Clearing skies will allow temperatures and mixing heights to quickly drop off in the evening, so residual smoke may settle near the ground. OUTLOOK (SATURDAY-MONDAY) An upper-level ridge will extend from southwestern Oregon to northeastern Washington on Saturday. Winds aloft and at transport level will remain north-northeasterly with continued drying and warming of the air mass across the region. After a chilly start, with surface-based morning inversions, plenty of sunshine will help afternoon temperatures recover to near normal. An offshore cold front is forecast to push the upper-level ridge axis just east of the region by Sunday afternoon. Temperatures will warm to slightly above normal with transport winds becoming light northerly. The cold front is forecast to sweep across the region Monday afternoon with north-northwesterly transport winds ushering cooler air back into the region along with some clouds and a risk of a mountain shower or thunderstorm.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 TUESDAY An upper level low drops in from the northwest during the day Tuesday. Skies will be partly to mostly cloudy with scattered showers. Relatively cool air aloft will destabilize the atmosphere and help push maximum mixing heights to above 5000 feet. This will give generally good smoke dispersal conditions to the region. OUTLOOK (WEDNESDAY-FRIDAY) The upper low moves southeast into southern Idaho on Wednesday. Cooler daytime temperatures will limit maximum mixing heights a bit but smoke dispersal conditions should be at least fair to good most areas. There will still be enough moisture for some scattered showers. By Thursday the upper level low will move east northeast into south-central Canada but some troughiness will hold back across the Pacific Northwest. Friday looks dry but partly to mostly cloudy. Mixing heights both Thursday and Friday should be quite high yielding generally good smoke dispersal conditions. 2. DISPERSION TUESDAY Mixing height 3200 - 4200 ft during the morning. Mixing height rises above 5000 ft during the afternoon and evening. Transport wind NNW to NNE at 4 - 8 mph during the morning and afternoon.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 FRIDAY A cool upper-level trough will remain over Washington and Oregon. Another disturbance will rotate into the trough, from off the southern British Columbia coastline, and take up residence just off the northern Oregon coast. That will maintain a cool and moist southwesterly flow aloft over Oregon. Some sunshine will allow temperatures to recover close to normal. However, daytime heating will combine with cool air aloft and the approaching weather disturbance to destabilize the atmosphere. The chance of showers and thundershowers will increase in the late afternoon and evening. Mixing heights should be high in the afternoon. The chance of showers or thunderstorms will continue to increase through the night and into Saturday. OUTLOOK (SATURDAY-MONDAY) An upper-level disturbance will move onshore and over western Oregon Saturday with southwesterly flow aloft continuing the chance of showers or thundershowers across south-central Oregon. High temperatures should cool back to around 10 degrees below normal with transport winds turning more onshore in the afternoon and evening. The disturbance is forecast to move across Oregon Sunday with the flow aloft turning more westerly. The main shower threat should push just north of the region, but showers are still possible, especially north. High temperatures should remain well below normal with continued onshore flow at the transport level. The onshore flow will relax with transport winds turning more northerly on Monday, as a transitory upper-level ridge moves over Oregon. Skies should become mostly sunny with temperatures recovering close to normal. High afternoon mixing heights are expected during the outlook period. 2.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 SATURDAY A broad and cool upper-level trough will remain over Washington and Oregon. The center of an upper-level disturbance, embedded within the broad trough, will slowly sag southward along the Oregon coast. The counterclockwise circulation around it will produce a moist and somewhat unstable south-southwesterly flow aloft over the state. Skies will be partly to mostly cloudy with a chance of showers and thundershowers. High temperatures should cool to about 5-10 degrees below normal. Daytime heating and cool air aloft will yield high afternoon mixing heights with onshore transport winds. OUTLOOK (SUNDAY-TUESDAY) The center of the embedded upper-level disturbance will move over southwestern Oregon early Sunday and slowly progress eastward, to over southeastern Oregon, by Sunday evening. Scattered showers are likely Sunday morning but should decrease later in the day, as the flow aloft turns more westerly and air mass begins to stabilize. High temperatures should remain about 10 degrees below normal with northwesterly transport winds. A weak and transitory upper-level ridge will move over western Oregon Monday and drift eastward, to over eastern Oregon, on Tuesday.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 WEDNESDAY An upper level trough deepens and moves toward the Pacific Northwest on Wednesday. The trough axis remains offshore for southwesterly flow aloft. Moisture will be limited but there is a possibility of showers or thunderstorms during the afternoon. It should be warm enough to push afternoon mixing heights to above 5000 feet for good smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) Thursday sees a westerly flow aloft with embedded disturbances moving with the flow. Again, very limited moisture so rain is not expected. Mixing heights should push high enough for good smoke dispersal conditions. A broad trough aloft sets up for Friday. Look for dry weather, partly cloudy skies, and good smoke dispersal conditions. Saturday it's back to a westerly pattern aloft with weak embedded disturbances but not much moisture. High afternoon mixing heights will again be the rule on Saturday. 2.
