Our midweek weather system is taking its sweet time crawling through Minnesota Wednesday.

The GOES-16 infrared satellite loop above shows the system’s moisture plume feeding moisture almost directly north into the Upper Midwest. Note how the overall system is making very slow eastward progress.

That means scattered rain bands will shift slowly east as they move northward. Expect rain bands to linger in Minnesota into Thursday before the system finally pushes to the east by Friday.

NOAA’s NAM 3 km resolution model shows the rain band edging slowly eastward into Thursday morning. The loop below runs between 4 p.m. Wednesday and 7 a.m. Thursday.

Soaking rains

Most of Minnesota will get rain with this system. The most soaking rainfall over an inch favors central Minnesota. The Twin Cities looks likely to end up with between about .50 inch and 1 inch rainfall.
