Spotty thunderstorms north tonight favor Twin Cities area Saturday afternoon

Rainfall coverage will be localized. Breezy and cooler Sunday.

We’re tracking a cold front dropping southward through Minnesota through Saturday.

As of this post late Friday, the front is crossing the Canadian border dropping southward. The front has sparked scattered thunderstorms this afternoon from Hallock through Roseau to Warroad, and Baudette to International Falls. The MPR interactive radar at 5:20 pm Friday is lighting up with lightning strikes late Friday afternoon from near Fargo and Bemidji to International Falls.

Expect scattered storms to gradually drift southward along the frontal zone into tonight.

Scattered storms Saturday

The front will drift southward through central Minnesota and the Twin Cities area Saturday. Scattered thunderstorms will fire along the frontal boundary favoring Saturday afternoon into the evening.

NOAA’s FV3 model tracks the line of storms across northern Minnesota Friday evening, then watch as spotty storms redevelop in the heat of the day Saturday afternoon around the Twin Cities and especially south.

Rainfall coverage will be spotty once again with this fairly weak cold front. If you get under a brief downpour you could pick up .25” to .50” of rainfall. There may even be some local rainfall totals over an inch under a couple of slow-moving cells. But many areas will see less than that, or miss the rain Saturday.

NOAA’s FV3 rainfall output shows the chaotic patchwork nature of likely rainfall through Saturday.
