SPOT WEATHER FORECAST

12/10/2008 Weather Discussion: Radar shows a few light showers lingering in the mountains. The atmosphere should begin to dry out as high pressure builds over the PNW during the next few days. Long- term models shows a nice cool wet system arriving Friday. This will be a good snow producer for the mountains. Cold arctic air will then flow down from the Frazer River valley flooding the state with unseasonable cold temperatures. Could see low temps near or below 0f by Sunday/Monday. (protect those pipes) Forecast from Wednesday 4pm to Thursday 4am Precipitation 0 in. Water 0 in. Snow Temperatures Low 28 High 32 Winds 0-5 W Forecast for Thursday 4am to 4pm Precipitation 0 in. Water 0 in. Snow Temperatures Low 28 High 30 Winds 0-5 N TRENDS AND TIMING Precipitation: The light precip. should be done sometime after 4pm today. Dry conditions will persist until Friday morning. Friday’s storm is just a bit too far out to be confident in snow totals, so I will leave that for tomorrow. Freezing levels: Freezing levels will slowly trend down from 5000’ to 4000’ overnight. Freezing levels should hover near pass level tomorrow before they fall further on Friday. Winds: Light westerly winds will shift to north then east tomorrow. There could be a much more interesting wind issues during the weekend.
