An upper level trough of low pressure (the shaded ”U” shape on the jet stream) slowly moving into the Pacific Northwest producing the chance of rain and thunderstorms with small hail while lowering mountain snow levels down to the passes where some snow has been falling. A frontal system moved through Monday afternoon increasing the chances for showers and thunderstorms. (I had a hail storm over my neighborhood at 2:15 PM that lasted about 20 minutes dumping enough hail to whiten the street and the roofs. Weak high pressure will dry us out a bit Thursday, but low pressure returns for more rain Friday through the weekend.
