Right now there are a few light showers to the north and on the western slopes of the Cascades, but little else going on (see radar) in the area. But when I took at the latest satellite picture, I was taken aback (see attached)--a huge plume of moisture over the Pacific headed for the West Coast and the Gulf of Alaska...and we will get a piece of that starting tomorrow evening.
The approaching system will bring much warmer temperatures and rain in the lowlands and over the lower slopes of the Cascades. But the initial few hours could very well bring snow to the normally cooler locations...and even we
t snow to the lower elevations. Cold air will be in place and falling precipitation will cause cooling due to evaporation in the dry air near the surface and melting of snow into rain. I have attached 24-h snow maps ending 4 AM Monday and Tuesday so you can see this. By the second 24-h time period the lowlands are all rain..but the mountains will get hammered with snow above roughly 3500 f
t. Perhaps the ski resorts can catch up on lost business...PS: Thanks for all your help with the questionnaire...will let you know the results...
