STEVENS PASS MOUNTAIN WEATHER

11/17/2010 Weather

24hr SNAP SHOT - Starting at NOON today:

Water - .5-.75  Snow 6-10"
Freezing levels - 4000' dropping to 2000'
Winds - WSW 5-10 gusty.


General Discussion: A cold front will swing in from the NW today bringing snow to the mountains.

Long-term: The low pressure cell will continue to spin snow showers into the mountains through the weekend as it drifts SE of the State. A cold air mass dropping in from Canada will keep surface temperature unseasonable low through the beginning of next week.

TRENDS AND TIMING
Precipitation: Moderate snow will fall for a few hours today and then begin to taper to showers after the front passes. Snow showers, some heavy at times, will continue through the rest of the week.

Snow Totals: If the low pressure system stalls off the southern Washington coast, like models are indicating, snow totals could exceed 20” by the end of the weekend. I am a bit skeptical of this, but possible.

Freezing levels: Freezing levels will hover near 4000’ today and then begin to fall tonight. Freezing levels will lurk around the 2000’/2500’ level through Friday.

Winds: Some gusty winds will be possible with the passing of the front, but nothing significant. WSW flow will through Friday as well. jdm
