Flood Warnings in effect for parts of the Northland; Additional storm reports from May 12-13. Mild temperatures and breezy this weekend with isolated showers/t-storms

6:18 PM Friday, May 13, 2022

Will get a break from the stormy weather as of late, but there is a chance that we may see an active pattern return once again later next week.

Two cold fronts will be moving through the Northland, one on Saturday and another one on Sunday. Weak lift accompanying these fronts along with a pool of cold air aloft (500mb temps -20 to -25C) and warmer temps near the surface will help create a slightly unstable atmosphere this weekend, and the result from all this is for a few showers and thunderstorms to move across the Northland Saturday and again on Sunday. Coverage of this rain looks widely scattered both days with many of us not getting any rain at all the entire weekend.

Will have some sun Saturday and Sunday with highs in the 60s and 70s on Saturday and ranging from the low 60s to low 70s on Sunday.

Winds will generally be out of the southwest this weekend at 10 to 20 mph with gusts to 35 mph, but there is a possibility for an easterly wind direction near Lake Superior Saturday morning into early Saturday afternoon before winds shift to the southwest.

Simulated radar forecast valid 7 AM Saturday to 7 PM Sunday.

The spring of 2022 has been awfully wet in northeast Minnesota and northwest Wisconsin.
