DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 An upper ridge will cover the eastern Pacific on Thursday with upper flow generally northerly over the Pacific Northwest. This is a dry pattern with cool night-time temperatures. In the north offshore flow will be quite brisk but expect only light easterly flow in the south. Mixing heights will be low for poor to marginal smoke dispersal conditions. OUTLOOK (FRIDAY-SUNDAY) On Friday an upper level trough over southwest Canada will drop south-southeast into the region. Moisture will be limited but there is a possibility of some snow flurries with this system. The low will settle in over the area for Saturday and Sunday. Models differ on the exact location and configuration of this low but there seems to be consensus on only limited moisture. Temperatures will be very cold, coldest of the season, and there will be a continued possibility of snow flurries. With the upper low mixing heights will rise for improved smoke dispersal conditions. 2. DISPERSION THURSDAY Mixing height below 1000 ft during the morning.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 Cold weather will continue. Upper flow over the Pacific Northwest is essentially northerly. A weak upper trough will drop down on the northerly flow. Satellite pictures show some clouds with this feature but computer models indicate very limited moisture. There could be a scattered snow shower or two late tomorrow but I expect no significant accumulation. Mixing heights will generally be around 3500 feet for fair smoke dispersal conditions. OUTLOOK (WEDNESDAY-FRIDAY) A dry upper flow continues over the northwest Wednesday, however following the passage of Tuesday's weak upper trough the flow turns a little more north-northwest. The air mass stabilizes for less favorable smoke dispersal conditions. Northwesterly flow aloft continues in the north on Thursday but westerly flow aloft begins to push into northern California and SW Oregon for improving smoke dispersal conditions. A weak upper disturbance moves over southern Oregon and northern California Friday as the cold weather pattern slowly breaks for continued improvement in smoke dispersal conditions. 2.

But not before the entire Pacific Northwest experiences another bone-chilling night. Daytime temperatures on Thursday will likely be a few degrees warmer than on Wednesday. Very low mixing heights will continue and burning is not recommended. OUTLOOK (FRIDAY-SUNDAY) Upper flow goes westerly over the area on Friday. A weak weather system will spread generally light precipitation into southwest Oregon and that precipitation will move slowly into the region during the day. Mixing heights will improve and the southerly transport winds will continue. By Saturday expect light snow, slowly improving mixing heights, and a continued southerly transport wind. Sunday will see scattered showers and mixing heights near 5000 feet for good smoke dispersal conditions. 2. DISPERSION THURSDAY Mixing height below 1000 ft throughout the day.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 An upper level low pressure area will be over southeast Oregon and move southeasterly out of the state during the day. Expect some precipitation from this system but the cool air aloft near the low should provide high mixing heights and good smoke dispersal conditions. OUTLOOK (WEDNESDAY-FRIDAY) On Wednesday a strong upper ridge with its axis about 300 miles west of the coastline will settle in. This will give a cool north to north-northwest upper flow pattern to the region. Subsidence with the ridge will lower mixing heights and smoke dispersal conditions will become poor to unfavorable. The ridge slowly moves east Thursday and Friday but remains to the west of the state. This will keep conditions dry and stable through at least Christmas. 2. DISPERSION TUESDAY Mixing height 3200 - 4200 ft during the morning. Mixing height rises to above 5000 ft during the afternoon then lowers to 1500 - 2500 ft during the evening. Transport wind WNW to NNW at 10 - 20 mph. Surface wind WNW to NNW at 8 - 14 mph during the morning and afternoon. Surface wind decreases to NNW to NNE at 5 - 9 mph during the evening. OUTLOOK: WEDNESDAY Mixing height below 1000 ft during the morning rising to 1000 - 1700 ft during the afternoon. Transport wind NNW to NE at 6 - 10 mph during the morning becoming light and variable during the afternoon. THURSDAY Mixing height below 1000 ft throughout the day. Transport wind light and variable.

ISSUED: Tuesday, December 22, 2009 2:40 PM Jim Little 1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 ** Dry and Stable Period Next Few Days ** ** Unfavorable Smoke Dispersal Conditions ** Pacific Northwest Weather will be dominated by an upper ridge through the end of the week. On Wednesday the axis of this ridge will be about 200 miles west of the coastline and will essentially remain stationary throughout the day. At the surface highest pressures will be over southern British Columbia. This will give light north to northeast winds to most areas. Mixing heights will remain below 2000 feet for poor smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) The upper ridge continues its slow eastward movement. On Thursday it is just off the coast and on Friday the ridge axis finally moves over Oregon and Washington. The ridge pattern starts to slowly break down on Saturday with only a marginal improvement in smoke dispersal conditions. 2. DISPERSION WEDNESDAY Mixing height below 1000 ft during the morning. Afternoon mixing height rises to 1200 - 2200 ft then lowers below 1000 ft during the evening. Transport wind light and variable and controlled by local terrain during the morning. Transport wind increases to NNW to NE at 4 - 8 mph during the afternoon and evening. Surface wind light and variable and controlled by local terrain. OUTLOOK: THURSDAY Mixing height below 1000 ft during the morning rising to 1000 - 1600 ft during the afternoon. Transport wind light and variable. Surface wind light and variable. FRIDAY Mixing height below 1000 ft throughout the day. Transport wind light and variable. Surface wind light and variable.

ISSUED: Wednesday, December 23, 2009 2:30 PM Jim Little 1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 ** Dry and Stable Period Tomorrow and Friday** ** Unfavorable Smoke Dispersal Conditions ** ** Air Stagnation Advisory issued for Rogue Valley ** Pacific Northwest Weather will be dominated by an upper ridge through the end of the week. On Thursday the axis of that ridge will be right along the Oregon/Washington Coast. Subsiding air with the ridge will make for very stable atmospheric conditions. At the surface higher pressure over eastern Washington and northern Idaho will give easterly winds in the northwestern portion of Oregon but winds in the Rogue Valley will be light. The east winds could offer some burn opportunities over the north coast range, otherwise smoke dispersal conditions will remain poor. OUTLOOK (FRIDAY-SUNDAY) The upper ridge continues to move eastward Friday but little change is expected with respect to smoke dispersal conditions. Computer models are inconsistent on how the pattern will break down but there is an increasing chance of precipitation later Saturday and Sunday as weak disturbances move in from the west. This should help to improve smoke dispersal conditions. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1000 - 1500 ft. Transport wind NE to E at 9 - 15 mph.
