KEY MESSAGES

- Light rain and drizzle today, spreading more east of the Red River after mid morning today. Rain arrives Monday and ends Tuesday morning, with potential for 1 inch or more of rain in some areas. These rain events may impact outdoor activities and harvest.

UPDATE

Issued at 642 AM CDT Sat Sep 26 2026

Light rain, drizzle and low clouds have advanced northward as expected. Light rain will continue much of the day with the band transitioning more east of the Red River after mid morning. Still though with low clouds could be drizzle in eastern ND this morning once the rain area moves thru. Kept messaging the same with the focus for heavier rainfall (probs 1 inch or more) roughly Jamestown-Grand Forks-Baudette zone. Though this zone of higher qpf is subject to change as models do differ a bit.

..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.
