SPOT WEATHER FORECAST

11/11/2009 Weather Discussion: NW flow will continue to push bands of moisture through the PNW for the rest of the week. Tomorrow’s band is tracking to the south of Stevens, so not expecting much from that. A strong cold front will bring our next batch of significant snow on Friday. Long-term models show a wet frontal system bringing high freezing levels and possible some rain to the mountains for the second part of the weekend. There is cold air following this system so could see a rain turning to snow event for the start of the week. This is a bit far out to be confident in the details. 24 hour forecast starting at noon on Wednesday Precipitation Lt .25 in. Water 0-2 in. Snow Temperatures Low 24 High 30 Winds 0-5 W 0-10 SE TRENDS AND TIMING Precipitation: Light snow showers will persist over the Cascades for the next 24 hours.
