Still Two Clippers in the US

A clipper system is moving through the Great Lakes and Northeast on Friday, producing scattered showers and a few thunderstorms that may develop all the way down to the Gulf of America. The last clipper in this week’s train is moving through the Pacific Northwest and will be a potent one as it taps into some very cold air across Canada this weekend.

Highs: 20s/40s Canadian Prairies; 40s/50s Pacific Northwest, Northern Plains, Upper Midwest; 50s/60s Central Plains, rest of Midwest; 60s/70s Southeast; 70s/80s Southern Plains, Delta.
