SPOT WEATHER FORECAST

12/1/2009 Weather Short term: We can expect patchy clouds with sun breaks today. Clouds should thin with over all clearing through the night as high pressure builds over the region. Long-term: A high-pressure cell taking up the entire gulf of Alaska will bring dry and cold weather to the PNW for the extended period. When will this dry spell end? Long-range models are fighting over this – For now, let’s say late in the weekend or early next week. 24 hour forecast starting at noon on Tuesday Precipitation “ Water: 0 “ of Snow: 0 temperatures (F): 4000’ Low: 20 High: 26 5000’ Low: 16 High: 24 Winds speed/Direction Pass level: 0-5 E Ridge top: 5-10 E TRENDS AND TIMING Precipitation: High pressure and a stabilizing atmosphere imply no moisture available. Freezing levels: Freezing levels will hover around the 3000’ mark. But, as cool air filters in from the northeast interior, coupled with clear skies, surface temperatures could dip quite low during the next few days. Winds: East/off shore flow will continue through Thursday. jdm
