Heavy rain/snow is hitting the Pacific Northwest

2-3 different storm systems are riding the jet stream into OR, WA, and British Columbia with heavy precipitation.

Mid-level water vapor satellite 11/4/2021 6am. Active flow pattern.

The first storm system is abnormally warm with high snow levels between 6,000-8,000ft, but levels fall on Friday and Saturday to 3,000ft as colder air moves in.

Rain falling at Whistler/Blackcomb lower elevations, Village Cam 2,214′.

I’m forecasting heavy snow totals at mid-mountain and higher. Click on my forecast to enlarge:

This strong, moist PNW flow might continue next week as well. This is what you would expect during a La Nina pattern.
