SPOT WEATHER FORECAST

3/19/2009 Weather Discussion: Light snow/rain today with rising freezing levels. A cold front approaching will enhance the precipitation at times. This complex weather pattern will bring a mixed bag of features through the weekend. Long-term models show the low-pressure system in the Gulf of Alaska stalling, this tends to weaken and split the approaching storms. The weekend is look more like scattered snow showers with sun breaks. I don’t have a whole lot of confidence in the models at this point, so we will have to wait and see. Forecast from Thursday 4pm to Friday 4am Precipitation .25+ in. Water 1-3 in. Snow Temperatures Low 34 High 36 Winds 0-5 SW Forecast for Friday 4am to 4pm Precipitation .25+ in. Water 1-3 in. Snow Temperatures Low 34 High 36 Winds 0-10 SW TRENDS AND TIMING Precipitation: These systems have a distinct band pattern to them, so there will be periods of moderate precip and then some breaks. The snow is expected to change to rain below 4500’ this afternoon and then turn back to snow after the cold front moves through late tomorrow. Freezing levels: Freezing levels will trend up from 4000’ today to 5500’ overnight. The snow levels should hover somewhere in between through most of tomorrow. Freezing levels will fall below pass level after 4pm tomorrow. Winds: Light SW flow will continue through tomorrow- could see a brief gusty period as the cold front moves closer but nothing significant.
