KEY MESSAGES

- Thunderstorm chances increase Sunday and Monday

UPDATE

Issued at 653 AM CDT Wed Jun 11 2025

Nothing suprising going on as we past sunrise. Smoky, hazy sky. Elevated showers continue to move east just south of the ND border and just south of Grant county MN. Patchy ground fog formed around 530 am and in a couple spots was thick, but shallow via webcams. It will burn off fast, and coverage isnt like it was Tues AM.

..Thunderstorm chances increase Sunday into Monday

This wave moves out Friday....then a relatively quiet period Friday night/Saturday...before any potential system arrives from the west Sunday afternoon or Monday. Models have been highly variable with track, timing, strength of this next wave and how much unstable air will be brought north. GEFS ensembles and NBM have continued to indicate 70 pct of more than 1000 j/kg into central and southeast ND Sun aftn into Sun night. Depending on wave timng, it would look like the best chance for any organized t-storms would be Sun night or Monday. Severe remains to be seen as while we have more instability, with PWATs up to 1.5 inches it would argue maybe more heavier rain potential vs severe. This is the period we will continue to watch.
