Expect heavy snow through early Sunday morning for the Cascades, with an additional 12 to 18 inches possible. Snow levels will be around 3000 to 2000 feet, then lowering to 1500 to 500 late tonight. Travel in the passes will be affected, so be sure to dial 511, or go to www.wsdot.com/traffic/passes/ to get the latest information on pass conditions!
By Sunday afternoon and evening, snow levels will be where we could see some wet snow on the hilltops around the Puget Sound region and most models indicate a change from rain to snow underway in Southwestern Washington.
Sunday night into Monday morning when that cold low begins its trek into Western Washington and will continue through the day Monday. Models also indicate the timing will correspond with another push of cold, modified arctic air from the Fraser River Valley to bring snow levels down to the sea level as the low moves through. Those Fraser winds could reach gusts of 50-60 mph around Whatcom County and the San Juan Islands and could bring blowing snow and power outages. A high wind watch may be issued here as we get closer.
