The weather pattern hasn’t changed a whole lot since Saturday.
The Northland remains in a NW flow aloft today while an upper level low/trough continues to dig S-SE out of western Ontario.
Scattered showers occurred in parts of the Northland on Saturday, and more of the same can be expected this afternoon and early evening since the overall pattern remains nearly the same, but there is less instability in the atmosphere today compared to Saturday, so that lessens the chance for any thunder with the showers this afternoon.

14z HRRR model simulated radar forecast valid through 9 PM Sunday.
A few showers likely in northeast Minnesota and northwest Wisconsin this afternoon into early this evening, but rainfall amounts will be on the light side, generally ranging from a trace to perhaps up to 0.10 inches, similar to what we saw on Saturday.
Labor Day (Monday) is looking pretty nice in the Northland. Dry with highs mainly in the 70s, but the day will start out quite cool in some parts of the area, it is September after all. It’s possible we could see some 30s in the typical cold spots in our area early Monday morning.
Will see a strong trough and cold front move quickly through the area Monday night-early Tuesday morning with a chance for scattered showers or thunderstorms with that system. If enough moisture and elevated instability can build up ahead of this system Monday night, then we could see an isolated strong to severe thunderstorm threat in northeast Minnesota and northwest Wisconsin since there will be plenty of wind shear and strong winds aloft accompanying this system.
