Although the severe thunderstorm season is certainly winding down across the Northern Plains and Upper Midwest, thunderstorms can and do become strong to severe in our region in late September and even into October.
The sun angle is lower this time of year so there is less energy from the sun to add kick to any thunderstorms that form. But under the right conditions, other weather elements can make up for the lack of solar heating. Although not very common, thunderstorms in our region can still produce large hail, damaging winds, and even occasional tornadoes.
The Storm Prediction Center has places an area of eastern Minnesota and western Wisconsin under a slight risk for severe storms for Thursday and Thursday night.
