DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 ** Stable Pattern - Poor Smoke Dispersal Conditions Through Mid-Week ** Upper level heights hold strong in spite of a short wave moving into British Columbia on Monday. The atmosphere will remain very stable for poor smoke dispersal conditions except for possible brief marginal conditions mid afternoon. Mixing heights will remain low. Surface pressure gradients flat for light winds. Except for some morning fog in the valleys hazy fall sunshine will rule. OUTLOOK (TUESDAY-THURSDAY) The upper ridge builds on Tuesday and surface high pressure increases over the region. Generally sunny and pleasant weather will continue with light winds and poor smoke dispersal conditions. Wednesday will be a near repeat of Tuesday with very low mixing heights although winds aloft will increase a bit from the southwest. Real improvement will not occur until at least Thursday when smoke dispersal conditions will be fair with an upper trough approaching. This will cool temperatures aloft to help destabilize the atmosphere a bit. In addition transport winds will be stronger from the south by Thursday. 2.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 ** Stable Pattern - Poor Smoke Dispersal Conditions Continue ** A weak pacific weather system moving through British Columbian and northwest Washington Monday and Monday evening will be well to the east of the area tomorrow. This will allow the upper level ridge to strengthen for very stable conditions over the region. Expect fair weather but low mixing heights, mostly south to southeasterly winds, and generally poor smoke dispersal conditions. OUTLOOK (WEDNESDAY-FRIDAY) Wednesday is a transition day as the upper ridge axis shifts eastward. Expect some improvement in smoke dispersal conditions. Winds will be generally light southerly. By Thursday an upper trough will be approaching as the upper ridge axis moves out of the northern Rockies and into the northern plains. Smoke dispersal conditions will improve considerably by Thursday. Winds aloft will be southerly and surface winds will pick up from the south. A Pacific cold front will reach the coast late in the day and spread rain eastward into the region by Friday morning. Friday expect cloudy, showery weather most areas with good smoke dispersal conditions and a generally southerly wind early, shifting to northwesterly later in the day. 2.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 A very deep upper level low will sit in the northern Gulf of Alaska on Thursday. This will support a very deep surface low in the same location. The surface low to the north will give the Pacific Northwest a strong south-to-north pressure gradient for strong south winds through much of Oregon. A Pacific cold front crosses the Cascades and brings rain to the region overnight Thursday and into Friday. High mixing heights and good southerly flow will make for good smoke dispersal conditions. OUTLOOK (FRIDAY-SUNDAY) The upper low remains in the northern Gulf of Alaska and a strong upper level jet (120mph) swings around the bottom of the low and into the Pacific Northwest. Several weather systems will impact the area during the outlook period but none of them appear particularly strong. Expect showers Saturday then just scattered showers Sunday.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 A trough in the Gulf of Alaska will move closer to the Pacific Northwest giving southwesterly flow aloft over the region. The atmosphere should be fairly unstable and mixing heights will be 5000 feet or above for fair to good smoke dispersal conditions. Skies will be mainly partly cloudy with just a chance of a shower. OUTLOOK (WEDNESDAY-FRIDAY) The upper level trough moves west to east across the Pacific Northwest during the day. Subsidence behind the trough starts to stabilize the atmosphere. Mixing heights will fall and smoke dispersal conditions become less favorable. By Thursday temporary ridging aloft suppresses mixing heights and limits smoke dispersal smoke dispersal conditions. Mixing heights will be near 3500 feet most areas. A strong upper trough approaches Friday and cooler air aloft with this system helps destabilize the atmosphere and improve burning prospects. 2.

A forecast and instruction will be issued by approximately 8:00 AM Thursday morning. 1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 Next upper level trough moves toward the coast Wednesday. Rain (snow at the higher elevations) spills across the Cascades in the late afternoon and evening. Precipitation amounts fairly light. Low level flow southwesterly to northwest. This variability will necessitate careful selection of burn units. Air mass destabilizes as the trough nears resulting in good afternoon mixing. Daytime smoke dispersion good but mixing height falls rapidly in the evening. This could create problems for residual smoke from units near SSRAs. OUTLOOK (THURSDAY - SATURDAY) Unsettled weather continues to the weekend. Then on Saturday a ridge drifts over the Pacific Northwest. This will bring the mixing height down somewhat. Periods of rain, snow, or showers likely through Friday but as the ridge strengthens, Saturday should be dry. Daytime smoke dispersion fairly good but units that smolder into the nights are likely to create problems for nearby SSRAs. 2. DISPERSION WEDNESDAY Mixing height 2900 - 3900 ft through the morning, rising to 3800 - 4800 ft in the afternoon and lowering to 1200 - 2200 ft in the evening.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 Wednesday expect scattered showers with slowly decreasing mixing heights as the air mass slightly stabilizes. Further stabilization will occur on Thursday with generally dry conditions. Smoke dispersal conditions will be marginal to fair most areas. Another Pacific cold front will finally move into the region late Friday and this should improve mixing heights as it moves through. OUTLOOK (WEDNESDAY-FRIDAY) The upper level trough moves west to east across the Pacific Northwest during the day. Subsidence behind the trough starts to stabilize the atmosphere. Mixing heights will fall and smoke dispersal conditions become less favorable. By Thursday temporary ridging aloft suppresses mixing heights and smoke dispersal conditions further deteriorate. Mixing heights will be near 3000 feet most areas. A strong upper trough approaches Friday and cooler air aloft with this system helps destabilize the atmosphere and improve burning prospects. 2.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 ** Unfavorable burning situation due to very poor smoke dispersion. ** An upper level ridge of high pressure still dominates Pacific Northwest weather on Wednesday. The ridge axis will be on a line from central Nevada, across northeast Oregon and into northern Idaho. Upper flow will be from the southwest but any rain will be well to the north of Oregon. Low mixing heights and light winds will prevail. Recommend against any burning as smoke dispersal conditions will be very poor. OUTLOOK (THURSDAY-SATURDAY) On Thanksgiving Day the upper ridge moves east and an upper trough slowly approaches the Pacific Northwest. A Pacific cold front will move into western Oregon during the day and cooler air aloft should help to destabilize the atmosphere somewhat. Additional destabilization should improve dispersal conditions Friday. By Saturday temporary high pressure again takes over for deteriorating smoke dispersal conditions. 2. DISPERSION WEDNESDAY Mixing height below 1000 ft throughout the day. Transport wind S to SW at 10 - 16 mph. Surface wind S to SW at 4 - 8 mph during the morning. Surface wind becomes light and variable and controlled by local terrain during the afternoon and evening. OUTLOOK: THURSDAY Mixing height below 1000 ft early rising to 1000 - 2000 ft by late morning rising to 3000 - 4000 ft during the afternoon. Transport wind S to SW at 10 - 18 mph during the morning becoming SSW to SW at 20 - 34 mph during the afternoon. Surface wind S to SW at 6 - 10 mph. FRIDAY Mixing height 1500 - 2500 ft during the morning rising to 3000 - 4000 ft during the afternoon. Transport wind light and variable. Surface wind light and variable.
