KEY MESSAGES

- Widely scattered showers and storms are forecast across eastern North Dakota, Red River Valley, into west-central Minnesota. Northern storms are expected to not be severe, but there is a level 1 out of 5 risk for severe storms south of the I-94/Highway 10 corridor.

- More chances for showers and storms Sunday night, as well as mid to late next week. Some storms could be severe.

- Potential for heat-related impacts Sunday, and mid to late next week.

..Heat Sunday and again later in the week

ECMWF EFI shows a strong signal for warmer than average temperatures for the entire seven day period, with particularly high values on Sunday and Wednesday. With southeasterly winds the dew points will be on the rise. Probabilistic heat risk is around 20 to 30 percent chance for major impacts (excessive heat warning criteria) Sunday in the Red River Valley, and even higher values in west central MN for Wednesday. Will have to keep a close eye on heat impacts as we head into the day 3-7 period.

AVIATION /18Z TAFS THROUGH 18Z SATURDAY/

Issued at 1231 PM CDT Fri Jun 5 2026

VFR conditions with mainly some scattered to broken mid and high clouds at all sites. Biggest question will be scattered showers and thunderstorms moving through. Some showers will impact the KFAR area in the next couple of hours, so have some VCSH and prevailing rain for a short period. Less certainty with showers and thunderstorms just starting to develop. Have prob30s during the afternoon and early evening indicating convection for all but KDVL as cells are mostly firing to the south of that airport. Most activity will be to the south and west of our TAF sites by 00Z. Winds that are light and variable should steady out of the southeast by tomorrow morning, staying mostly below 12 kts.
