A wrapped-up October low-pressure system is driving areas of rain and thunder across central and southern Minnesota.

Scattered rain and embedded thunderstorms continue to push across Minnesota Wednesday. Some feisty thunderstorms are embedded within the larger rain zone. Pea-sized hail has been reported on the pumpkins with some of the stronger cells, like this scene from Lakeville in the southern Twin Cities suburbs.

The National Oceanic and Atmospheric Administration’s NAM 3 km resolution model tracks the low-pressure system and rain zones across Minnesota into Thursday morning. Most of the thunder cells will move through Wednesday afternoon, with more general showery weather through Wednesday night.
