KEY MESSAGES

- Risk for multiple rounds of severe storms starting late Saturday through at least Monday. All hazards are possible.

- Potential for heat impacts next week, including the Fourth of July weekend.

..Heat for the upcoming work week and holiday weekend

With upper heights rising over the Northern Plains, the ECMWF EFI shows a strong signal for above climo temperatures heading into next week. Probabilities from the NBM for highs above 90 degrees are over 70 or 80 percent for southern portions of our CWA on Monday, and chances are that high again for other days that week. Max wet bulb globe values are up into the high and extreme ranges for several days next week, and the extended range outlooks call for plenty of heat as we head into the Fourth of July weekend. Will start messaging heat impacts in our partner and public messaging.

AVIATION /03Z TAFS THROUGH 06Z SUNDAY/

Issued at 947 PM CDT Fri Jun 26 2026

Generally VFR throughout the TAF period, with a period of MVFR at both KBJI and KDVL later tonight into Saturday morning. A few showers are also possible tonight/Saturday morning. Therefore, maintained PROB30s at KDVL, KGFK and KTVF to account for rain chances. No additional thunderstorm activity is anticipated Saturday afternoon at this time. However, beyond the end of the TAF period Saturday night, a line of storms from western North Dakota will push from west to east, and likely bring aviation impacts. Some of these storms may begin to impact KDVL at the tail end of this TAF period, but focus on using PROB30s in the shorter term precluded any inclusion of them at that range in the TAF.

Outside of ceilings, winds will increase quite dramatically Saturday afternoon. Gusts of 30 knots or stronger are forecasted in KFAR, KGFK and KDVL. Gusts should decrease after sunset on Saturday. Wind direction will remain generally out of the southeast throughout the TAF period.
