12/4/2010 Weather
24HR SNAP SHOT starting at NOON today
Water - 0 Snow 0
Freezing levels - 1000' rising to 3000'
Winds - 5-15 E
General Discussion: The weekend will continue with dry and cool weather.
Long-term: A pattern change, fueled by a massive low pressure system building in the Gulf of Alaska, will bring warmer temperatures and moderate to heavy precipitation to the PNW. This will all begin to affect us late Tuesday night or Wednesday morning. This has potential to be an ugly storm with freezing rain, snow, heavy rain and flooding in the low lands. Confidence on the details is low, so I will wait until tomorrow or even Monday to see what this all means for the Pass.
TRENDS AND TIMING
Precipitation: Scattered clouds and sun breaks with no precipitation will continue today. A passing snow shower or two will be possible tomorrow.
Freezing levels: Freezing levels will begin to rise tomorrow morning. They are expected to rise to 2500’-3000’ by noon.
Winds: Brisk east flow will strengthen today. jdm
