DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 An upper level low sets up about 200 miles west of Waldport, Oregon giving south to southwest flow aloft. An upper short wave in this flow sill bring showers mainly to central Oregon with those showers moving northward during the evening hours. (OUTLOOK) THURSDAY - SATURDAY On Thursday the upper low backs off and moves west, farther off the coast. The upper short wave will rotate out of the state into Washington early in the morning leaving the region dry with a southerly flow aloft. Expect good mixing heights and good burning conditions most areas. On Friday the upper low continues off the coast with another weak short wave moving northward across the region producing scattered showers. On Saturday a front develops offshore and moves to the northern coast late in the afternoon. Elsewhere expect dry weather with strong southerly transport winds and mixing heights high enough for good smoke dispersal conditions. 2.

Another spoke of energy is forecast to rotate around the trough and over eastern Oregon tonight and early Thursday, with increasing rain and snow showers. Snow levels should be around 5-6000 early Thursday and rise to near 7000 feet Thursday afternoon. Transport winds will become northwesterly with 4-5000 foot mixing heights. Showers should end by Thursday evening, as the flow aloft dries out and turns more northerly OUTLOOK (FRIDAY-SUNDAY) A weak weather system will push into southern British Columbia on Friday, with transport winds turning west-northwesterly by late in the day. After a cold morning, with very poor mixing, ventilation will improve significantly with the daytime heating Friday afternoon. An upper level trough is forecast to slide across eastern Washington and northern Idaho Saturday and early Sunday, with the flow aloft turning westerly. This system will bring back a chance of showers to mainly the northern. A weak upper-level ridge is forecast to move over western Oregon Sunday afternoon with a dry northwesterly flow aloft. Morning inversions will give way to good afternoon ventilation conditions. 2. DISPERSION THURSDAY Zone 630 and 632: Mixing height 1800 - 2800 ft during the morning.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 THURSDAY A cold upper-level trough will shift eastward, to over the northern Rockies, with a northwesterly flow aloft over Oregon. Snow levels will start out near 2500 feet in the morning and rise to around 3500 feet in the afternoon. The air mass will still be somewhat unstable with daytime heating increasing shower activity in the afternoon. Precipitation will be enhanced on western slopes of mountain ranges. Afternoon mixing heights will rise above 5000 feet for good to excellent smoke dispersal conditions. Surface temperatures will be well below normal. OUTLOOK (FRIDAY-SUNDAY) The strong upper-level trough will continue to shift eastward with the flow aloft over Oregon becoming progressively drier and more northerly. The air mass will remain unstable enough for daytime heating to trigger scattered afternoon and evening showers on Friday with good to excellent smoke dispersion. Skies will begin clearing Saturday and Sunday with only a slight chance of afternoon showers. Chilly overnights will make for lower morning mixing heights, but afternoon smoke dispersion should be good on Saturday and fair on Sunday. The snow level will rise from 3500 feet, on Friday, to 6000 feet by Sunday. 2. DISPERSION THURSDAY Zone 630 and 632: Mixing height 3800 - 4800 ft during the morning.
