KEY MESSAGES

- Heat impacts are expected to continue across portions of the area through the remainder of this week.

UPDATE

Issued at 941 PM CDT Tue Jul 14 2026

Allowing the Extreme Heat Warning to drop at 10pm with a Heat Advisory going into effect beginning at 10pm tonight through 10pm Thursday as peak afternoon heat indices Wed/Thur south of HWY 2 will be in the mid to upper 90s and Wet Bulb Globe will creep over 80 continuing the heat impacts for the region.

..Heat Impacts This Week

Areas to the south of a slow moving cold front are expected to remain quite warm through the end of this week. Afternoon temps in the 90s will combine with dew points generally in the upper 60s to low 70s to bring heat index values of around 100 degrees each afternoon. The best chances to see these higher heat indices will be in the southern Red River Valley and adjacent areas of southeast North Dakota and west central Minnesota. Temperatures in the central Red River Valley could climb back into the low 90s; however, lower dew points should keep heat index values in the middle to upper 90s.

AVIATION /12Z TAFS THROUGH 12Z THURSDAY/

Issued at 635 AM CDT Wed Jul 15 2026

A few thunderstorms have developed this morning. Impacts from these storms should remain confined to KTVF through about 14z, then taper off. Therefore, a PROB30 was added into the KTVF TAF. Clouds at about 5000 AGL should clear as we go through the morning hours. The one other concern into the afternoon/evening is if smoke penetrates as far east at KFAR and/or KBJI. At this time maintained FU at KFAR, but did not add it anywhere else, as model guidance and upstream observations leave quite a bit of uncertainty in the smokes eventual track/intensity/timing. Winds will increase into the afternoon up to about 15 knots with a few gusts. Following a diurnal trend, winds will decrease after sunset with any remaining gusts dropping off and sustained values falling to under 10 knots.
