KEY MESSAGES

..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.

Issued at 1233 PM CDT Tue Jul 14 2026

VFR conditions prevail at all TAF sites this afternoon. Look for an isolated thunderstorm or two north of KTVF as a cold front continues southeastward across the area. Winds will shift to the north and northeast following the front this afternoon and evening, generally in the range of 7-12 knots, but with a few gusts up to 25 knots at KDVL. As the wind shifts and increases, there could be brief periods of LLWS tonight into early Wednesday morning.
