It’s raining in parts of Minnesota today. That fact could be a headline all on its own in this summer of expanding, deepening drought.

Thursday and this weekend bring the best opportunities for rainfall to Minnesota. A weak frontal system crosses Minnesota Thursday. It’s not very strong, but it will be enough to squeeze out scattered rain and a few thunderstorms.

NOAA’s HRRR model paints scattered blips of rain and a few thundershowers Thursday. The loop below runs between 1 a.m. 10 p.m. Thursday.

Severe weather is unlikely. NOAA’s Storm Prediction Center does not have any severe weather risk areas for Minnesota Thursday.

Better chances for significant rainfall this weekend

This weekend brings a stronger system and better chances for significant rainfall. A low-pressure wave tracks eastward from the Dakotas into Minnesota. The Canadian model paints scattered rain and thunderstorms across Minnesota this weekend.
