.DISCUSSION... Issued at 320 PM CDT Sun Sep 7 2025
...Synopsis...
Cooler air retreats east today with a ridge building to the west. Lows could fall into the upper 30s in some areas tonight, although most locations should see temperatures in the 40s. Heading into Monday, moisture and warmer temperatures return to the area, with afternoon highs in the 70s to near 80 degrees. A shortwave is expected to traverse the region late Monday evening through early Tuesday morning, bringing a chance for showers and thunderstorms to parts of southeast North Dakota and west central Minnesota. While a few storms could produce small hail, the probability for severe thunderstorms is quite low. Heading into Tuesday afternoon, the H5 ridge works slowly eastward, with the axis centered in western North Dakota. By Wednesday, the ridge axis will be near the ND/MN border. Temperatures will reflect this as WAA continues, and afternoon highs Tuesday and Wednesday are expected to be in the upper 70s to near 80 in many areas. Moving into Thursday, southwest flow moves into western and central North Dakota as the aforementioned ridge continues to the east. Shortwaves will traverse the upstream side of the ridge, bringing showers and thunderstorms back into the forecast for Thursday onward into the weekend. This also sets the stage for an unsettled pattern that could support several rounds of strong thunderstorms, although details at this time are minimal. Looking at GEFS ensemble probability for 1000 J/Kg of CAPE, parts of the southern Red River Valley and west central Minnesota are around the 50 to 60 percent mark Friday afternoon and evening.
