KEY MESSAGES

- There is a level 2 out of 5 risk for severe thunderstorms this afternoon and evening over the central and southern Red River Valley as well as portions of southeastern North Dakota. A level 1 out of 5 risk for severe thunderstorms for northeastern North Dakota and parts of northwestern and west central Minnesota.

- Heat returns for the weekend.

..Heat into the weekend

With upper ridge building back north and southerly winds returning ahead of the surface trough over the High Plains, temps will warm back up over the weekend. The ECMWF EFI has 70 to 80 percentile signal for above average temperatures, and by Sunday the NBM probabilities of over 90 degrees in the Red River Valley are over 60 percent. Dew points currently in the upper 50s to low 60s, so heat index doesn't look too bad yet but will continue to monitor as some of the other heat risk indicies are creeping upward.

AVIATION /18Z TAFS THROUGH 18Z THURSDAY/

Issued at 1231 PM CDT Wed Jun 3 2026

Some ceilings at the VFR/MVFR cutoff at KDVL early this afternoon, but the rest of the TAF sites remain VFR. That could change as showers and thunderstorms push into eastern ND later this afternoon and then off into MN this evening. Kept most locations Prob30 for thunderstorms that could bring vis and even ceilings down to MVFR for a short time as they move through. Storms are expected to consolidate into a complex as they move east, so left KBJI at VCTS as they should get something later this evening into the early overnight. Have some MVFR ceilings at the MN airports after the convective activity moves through later tonight into tomorrow morning, but that should improve by the end of the period. ND airports should remain VFR outside of convective impacts.
