The National Weather Service has issued a severe thunderstorm watch until midnight for parts of south-central and southeastern Minnesota, and western Wisconsin.
The watch does not include the Twin Cities metro area, but the metro will see storms over the next few hours as they work their way into the area from the west/northwest.
Meanwhile, further south, mainly along the I-90 corridor, robust storm development has led to severe storms capable of producing damaging winds and large hail in excess of two inches in diameter.
Here's the official watch language from the weather service.
"Thunderstorms are developing along a surface cold front across southern Minnesota, and these storms are expected to intensify and spread east-southeastward through late evening. Large hail and damaging gusts can be expected with the storms along the front, with a mix of multicell clusters and perhaps some embedded supercells. Other elevated convection well north of the front may also pose some threat for isolated large hail/damaging gusts."
Stay aware of the weather as the night progresses.
