KEY MESSAGES

- The season's first summer-like temperatures are forecast next week starting Memorial Day Monday.

UPDATE

Issued at 630 AM CDT Sat May 23 2026

Showers are slowly moving to the northeast this morning with the most steady rain in far northwest Minnesota. Lingering mist, drizzle, and light rain prevail across much of the Red River Valley and points east. Temperatures are in the 40s across the region with light winds.

..Synopsis

Upper troughing is influence our region's weather today and tomorrow. This is bringing widespread rainfall this afternoon through tonight, along with lingering drizzle behind the rainfall into Saturday morning and perhaps afternoon (especially within Minnesota). General amounts are expected to be around half an inch, with some seeing around 1 inch (40% chance in portions of eastern North Dakota). Areas like northeast North Dakota may see very little in terms of amounts, less than a third of an inch.

As the upper trough and accompanying steady rainfall exits our region, stout upper ridging builds into the Northern Plains and central Canada. This will introduce the year's first stint of summer-like temperatures in the 80s and 90s through much of the week. These temperatures start Memorial Day this Monday.

Gusty winds, dry air, and hot temperatures may contribute to fire weather concerns Tuesday, although confidence is low in how gusty winds will get, as well as susceptibility of fuels to rapid fire spread given recent rainfall and green-up of vegetation.

With the building heat, instability will also be increased within the Northern Plains. However, there is deft in low level moisture as well as lack of more organized forcing for ascent to keep potential thunderstorm chances low. Should thunderstorms form, they may be strong to perhaps low end severe with small hail and gusty winds as main potential hazards in addition to lightning. Confidence is low in whether or not thunderstorms will develop, but could occur as early as Monday with a weak boundary sagging into our area from the north.

AVIATION /12Z TAFS THROUGH 12Z SUNDAY/

Issued at 630 AM CDT Sat May 23 2026

IFR to MVFR conditions prevail this morning at all TAF sites, with scattered showers lingering across eastern North Dakota, northwest Minnesota, and west central Minnesota. Heading into the late morning hours, much of this activity will be moving off to the northeast, allowing ceilings to improve slowly starting around midday. Look for MVFR ceilings this afternoon, with VFR conditions developing later in the afternoon and into the early evening. Winds will be out of the west to southwest through much of the TAF period, with 15-20 knot winds through early afternoon, and diminishing winds thereafter. Heading into the late evening and overnight period, winds become light and variable.
