UPDATE

Issued at 744 AM CDT Fri Jun 5 2026

Early morning showers and weak storms in the James River Valley continue to push east toward southeast ND through mid morning. Confidence is not high in these storms surviving into the afternoon.

With daytime heating, instability grows and convection is expected to begin around 2 PM allowing widely scattered showers and storms to develop. Relatively best chance (40%) for convection exists in eastern ND, Red River Valley, and west- central MN. As daytime heating wanes, convection is expected to cease, around 8 PM. While today's storms are not anticipated to be severe, a few storms may produce small hail and gusty winds to 40 mph. Localized half an inch of rainfall is also anticipated under storms.

Looking ahead toward this weekend and next week, guidance continues to bring hot temperatures and increasing moisture into our region. This will introduce potential for heat-related impacts Sunday as well as Tuesday through at least Thursday, potentially longer. This also brings chance for severe storms Sunday night as well as Tuesday, Wednesday, and potentially into late next week.

..Heat over the weekend

With southerly winds ahead of the surface trough over the weekend, there is a 60 to 90 percent probability for temperatures on Sunday to climb above 90 degrees. Dew points are also on the rise, and although apparent T values are still below 100, the heat risk and WBGT values on on the rise. Will continue to monitor for the need for any heat messaging over the weekend.
