DISCUSSION

Issued at 247 AM CST Mon Nov 9 2026

For today, surface low pressure will move from south central Canada towards Ontario, while surface high pressure builds over eastern Montana and works into the western Dakotas. This will result in westerly to northwesterly winds that will be breezy at times, especially east of Highway 83. Otherwise, expect another day of above average high temperatures reaching the 50s this afternoon. For Tuesday, above average temperatures will continue as a west CONUS ridge begins to amplify creating northwesterly flow aloft across the state. Embedded shortwave energy within this flow aloft could produce light rain from northwest to southeast. Depending on timing, a few flakes of snow could mix in as well in the northwest early Tuesday morning.

Beyond Tuesday, aforementioned ridge continues to amplify and very slowly drift eastward. As is often the case in these situations, the eastern half of the state is now favored to remain on the cooler side of the ridge with the western half on the warmer side. This translates to near to slightly below average highs east with above average highs west for the latter half of the workweek. By this weekend, the ridge should be in the process of breaking down as it slides fully over the Northern Plains bringing above average temperatures across the entire state this weekend and into early next week. Mostly dry conditions are forecast throughout this timeframe, although there is a low chance that weak shortwave energy could bring light precipitation to the area late this weekend or early next week.
