Weather Synopsis for Thursday & Monday
Dry, mild and quiet weather will define our weather over the next two days. One upper level low is currently positioned over California with another low is dropping south along the B.C. coast but remains well offshore. This leaves the Pacific Northwest alone with weak flow aloft and no weather systems nearby.
Freezing levels observed this morning by radiosondes (weather balloons) were all near 6000'. That's the anchor point where freezing levels will hang around for the next two days, with some slight changes due with daytime heating and nighttime cooling. Low elevation temperature inversions were not as pronounced as the past few mornings, in any event, expect lower elevation temperatures that are below freezing this AM to mix out and pop-up during mid-morning hours.
Mostly clear skies will sum up the next two days as well, with an increase in afternoon/early evening cumulus over the mountains in response to daytime heating. We can't rule out a stray shower somewhere in the Cascades in the afternoon, but the chance is not great enough to call it out in the forecast.
