KEY MESSAGES

- Additional light rain is expected tonight through Saturday night, and there is the potential for widespread soaking rain early next week. These rain events may impact outdoor activities and harvest.

..Rain tonight/tomorrow and again Monday/Tuesday

Shortwave will move in from the southwest tonight and provide some lift for light rain to develop in warm air advection. Highest probability of rainfall amounts are around the tenth of an inch to perhaps a quarter of an inch range. However, with some weak MU CAPE of up to 500 J/kg, can't completely rule out some convective cells with heavier amounts. The decent pressure gradient will bring some fairly breezy winds and with showers aiding mix down can't completely rule out some gusts up to 30 mph or so at times. A bit of a break on Sunday, then the stronger system arrives early next week. Still some slight variations in the exact track, but seem to be converging on a solution with deformation band precipitation setting up over northeastern ND and northwestern MN. Probabilities of amounts over 1 inch in this area are 60 to 70 percent, and there is even some 20 to 30 percent probabilities of over 2 inches Monday into Tuesday. A soaking rain seems likely, although could still be some variations in exactly where the heaviest amounts set up before the period arrives.

AVIATION /12Z TAFS THROUGH 12Z SATURDAY/

Issued at 1122 AM CDT Fri Sep 25 2026

Low ceilings will impact the region over the next 24 hours. Impacts to visibility are expected to be minimal today. Starting around 06Z Saturday, rain chances will begin to make their way into SE ND and spread northeast across the region. Visibility reductions are expected with these rain showers. By 18Z Saturday, precipitation is expected to be confined to NW MN and have exited into NE MN by 00Z Sunday. MVFR conditions will be common today with some VFR working into NW MN this evening and overnight. Increasing precipitation chances bring the return of IFR and isolated LIFR conditions Saturday as they move east.
