SPOT WEATHER FORECAST

11/12/2009 Weather Discussion: A cold front will bring snow to the mountains tomorrow. Long-term models show a high-pressure ridge building on Saturday, producing dry warmer weather. Another vigorous system is tracking in for Sunday with high freezing levels and plenty of moisture. I will wait for tomorrow’s model runs to get more confident in the detail. For now, it looks like snow changing to rain and then back to snow Sunday/Monday/Tuesday. 24 hour forecast starting at noon on Thursday Precipitation .25 -.5 in. Water 4-6” in. Snow Temperatures Low 20 High 32 Winds 0-5 SW Shifting W 5-15 mph TRENDS AND TIMING Precipitation: Snow will arrive here after 4am tomorrow morning. Snow will ramp up through the day and then quickly taper off overnight. Storm totals by 4am Saturday are being downgraded with every model run, so it is not looking like a huge snow producer for us. We will be lucky to get a foot. Saturday looks dry. Freezing levels: Freezing levels will slowly drop from 3000’ today to 1000’ by Saturday morning. Lowest surface temps could dip into the upper teens during the early morning hours. Cool temps should stick around until Saturday. Winds: Light SW winds will shift westerly with the passing of the front tomorrow morning. Could get some initial gusty ridge top winds in the morning but they should be short lived.
