Weather Synopsis for Tuesday & Saturday
An elongated trough digging offshore has spawned a surface low which should cross the northern tip of Vancouver Island this morning.
A warm front that gradually crossed Washington Monday and Monday night now sits around the US-Canadian border, leaving most of the region in the warm sector of the storm with snow levels around 4000-5000 ft. The digging trough offshore should lift the warm front slightly northward which may warm the Mt. Baker area slightly in the afternoon. An accompany cold front moving eastward should reach the coastal region by late in the day and as it approaches. Light W winds through the Passes may shift easterly as prevaily winds gain a more southerly component. This could lower snow levels enough for snow to return to Stevens Pass in the afternoon, but rain is expected to continue at Snoqualmie. Crystal may become unblocked as the flow shifts southerly.
Rain and snow should focus on NW Washington in the same general areas for most of the day before the frontal rainband pushes precipitation back into areas further south and east in Washington by late in the day.
The front crosses Washington State tonight with strong winds, rain/snow, and good cooling with the precipitation and behind the front. A secondary frontal band likely to bring another band of precipitation after midnight as well as further cooling such that in the early morning hours, snow levels should be below all the mountain passes.
Light snow shower activity should continue over Washington State (moderate over the Mt. Hood area) on Wednesday with a cold trough in place.
