SPOT WEATHER FORECAST

2/27/2009 Weather Discussion: It’s shaping up to be an amazing day. Sun, cool temps and fresh snow- sweet. A complicated low-pressure system tracking up from the south will bring warmer air and moisture to the PNW tomorrow afternoon and Sunday. This feature has a lot of what-ifs, mainly with freezing levels associated with the moisture. Long-term models show a cold front on the heals of Sundays weather, which will bring more moisture with cooling temps. The timing of all this is sketchy, but it will make for interesting conditions above and below the snow pack. Forecast from Friday 4pm to Saturday 4am Precipitation 0 in. Water 0 in. Snow Temperatures Low 16 High 20 Winds 0-5 E Forecast for Saturday 4am to 4pm Precipitation Lt .10 in. Water in. Snow Temperatures Low 20 High 26 Winds 0-10 E TRENDS AND TIMING Precipitation: Things should remain dry through most of tomorrow.
