UPDATE Issued at 820 PM CDT Wed Jun 3 2026

Severe thunderstorm environment remains supportive for isolated strong to severe thunderstorms, mainly across parts of the southern Red River Valley. Elsewhere, scattered showers and thunderstorms continue to bring periods of heavy rain to portions of northwest Minnesota, as well as southeast North Dakota. Rainfall rates within heavier storms are sufficient to support a mention of localized street flooding, and there have been a few reports near Lidgerwood as well as northern parts of Grand Forks. Widespread excessive rainfall impacts are not expected, however, brief street flooding remains possible during periods of heavy rain, mainly in urban areas.

..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 /06Z TAFS THROUGH 06Z FRIDAY/

Issued at 1135 PM CDT Wed Jun 3 2026

Thunderstorm activity has diminished at all TAF sites heading into the overnight hours. Look for VFR to MVFR conditions through the remainder of the overnight and into Thursday morning. Guidance is suggesting the development of MVFR ceilings at KBJI, KGFK, and KTVF after 07Z. The lower ceilings could persist through just after sunrise if they are able to form. Winds are expected to be light and variable through the early overnight hours, with a gradual increase out of the west early Thursday morning.
