KEY MESSAGES
- Rain showers and isolated thunderstorms are expected this evening through Thursday morning, with moderate totals greater than 0.25" likely.
- Additional light wetting rain is expected Friday night through Saturday night, and there is the potential for a widespread soaking rain with a system early next week. These rain events may impact outdoor activities and harvest.
..Synopsis
South to southwest H5 flow prevails today, with surface winds out of the south to southeast. Showers and isolated thunderstorms are expected overnight as a shortwave moves along the flow pattern. Most areas should see wetting rains, with the heavier amounts being in west central Minnesota and southeast North Dakota. Heading into Thursday, H5 flow becomes northwesterly, with surface flow remaining out of the south to southeast. Weak shortwave ridging will support slightly warmer high temperatures in the low 70s on Friday. Heading into Saturday, a trough is expected to traverse southwest flow into the Northern Plains, bringing another chance for rain into the region. Ensembles are in reasonably good agreement regarding additional rain chances late Sunday through Tuesday in association with a cold front. At this time, this system carries the potential for much higher rainfall totals over this period, with currently a 25 percent chance for 1 inch or more rain across much of eastern North Dakota and northwest Minnesota.
AVIATION /00Z TAFS THROUGH 00Z FRIDAY/
Issued at 637 PM CDT Wed Sep 23 2026
Scattered rain showers and isolated thunderstorms are beginning to move across eastern ND and coverage of rain showers should increase through the evening and overnight period. Visibility reductions in the 3-6sm will be common with moderate showers, with brief drops below 3sm. MVFR ceilings (already at KDVL) will spread west to east through the late evening and overnight, with IFR ceilings eventually develop after 06Z across the region. IFR is likely to linger over many locations Thursday with gradual improvement in the afternoon in central/northeast ND.
Southeast winds are likely to remain above 12kt through Thursday morning with periodic/less frequent gusts 20-25kt. Surface gradient shifts east as low pressure builds into northeast ND Thursday and winds should eventually drop below 12kt by midday.
