STEVEN PASS SPOT WEATHER FORECAST

12/5/2008 Weather Discussion: High clouds will develop today in response to a warm air invasion from the west. A sagging disturbance from the north will bring some rain and then eventually snow to the mountains for the remainder of the weekend. Long-term models show drying on Monday with another system tracking toward the PNW for the middle of the week. Models don’t currently agree on the timing or details for next week, so I will leave the guessing out for now. Forecast from Friday 4pm to Saturday 4am Precipitation .10 in. Water 0 in. Snow Temperatures Low 34 High 40 Winds 0-5 W Forecast for Saturday 4am to 4pm Precipitation .10 in. Water 1-3 in. Snow Temperatures Low 32 High 40 Winds 5-15 W TRENDS AND TIMING Precipitation: A possible short lived frontal wave could bring a few rain drops this afternoon/evening. But for the most part no precipitation expected until Tomorrow afternoon. The timing of the moisture is currently after 2pm tomorrow – We could see some rain to start but that is expected to slowly turn to snow through the night.
