It’s expected to be a rain-free Saturday afternoon and evening across much of Minnesota, but showers linger into Saturday afternoon in far southeastern Minnesota. Periods of rain will continue Saturday afternoon and into Saturday evening from southwestern Wisconsin into central Wisconsin.
Much of southern Wisconsin will have periods of rain today, tonight and Sunday. The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential rain pattern from 6 p.m. Saturday to 6 p.m. Sunday:
NOAA’s High-Resolution Rapid Refresh (HRRR) model shows a similar rain pattern this evening through Sunday afternoon:

Temperature trends
Saturday afternoon highs will be in the 60s in portions of far northern Minnesota, southeastern Minnesota and western Wisconsin, with mainly lower 70s elsewhere. Some spots in the metro area will reach the lower 70s. Our average Twin Cities high temp is 75 degrees this time of year.

Our temperatures rebound nicely as we go through the week. Twin Cities metro area highs are projected to reach the mid 70s on Monday and around 80 Tuesday, followed by lower 80s Wednesday, Thursday and Friday.
We could see above-normal temps from next weekend into the following week. The NWS Climate Prediction Center shows a tendency for above-normal temps in Minnesota and Wisconsin from Sept. 17 through Sept. 23:
Above-normal doesn’t necessarily mean hot weather in mid and late September; our average Twin Cities high temp on Sept. 18 is 72 degrees.
