A weather system pushes into Minnesota Thursday with widespread rain showers favoring southern Minnesota once again. 

The National Weather Service’s digital blend of models at the top of this post suggests one-half to 1 inch of fresh rain around most of the Twin Cities. One to 2 inches of rain looks common across southern Minnesota. 

If this were snow, we’d be forecasting 5 to 10 inches in the Twin Cities with more than a foot in southern Minnesota! Thankfully it’s warm enough for a cool rain.

The National Oceanic and Atmospheric Administration’s High-Resolution Rapid Refresh model seems to have a good grasp on rainfall coverage and timing. The forecast model loop below runs between 7 a.m. Thursday and 1 a.m. Friday.

The bulk of forecast models favor the heaviest rainfall south of the Twin Cities into Iowa with lesser amounts north of the Twin Cities. Here’s the European Centre for Medium-Range Weather Forecasts model output:

Temperatures Thursday will run in the cooler 50s across our region.

Rain will end early Friday and the sun may peek out Friday afternoon. Saturday will be the sunnier day of the weekend with a few clouds and slight shower chances Sunday. Highs will be mainly in the 60s this weekend, so not bad.

I’m still watching for a severe weather risk next Monday. 

Monday will feel more like June than late April. Highs will be in the toasty upper 70s to around 80 in southern Minnesota. If we hit 80 degrees in the Twin Cities Monday, it will be right in line with the average date for the first 80-degree temperature of the season, which is around April 29. 

Dew points will climb into the 60s. That will be fuel for strong to severe cells with an approaching front. 

The risk zone Monday runs from Minnesota southward into the Central Plains:
