..Severe Thunderstorm and Flash Flood Chances Tuesday

Heading into Tuesday, another round of showers and thunderstorms will bring the potential for hail, damaging wind gusts, and flash flooding into parts of the region. The best chances look to be along and south of the I-94 corridor at this time. Initiation favors the area including south central and southeast North Dakota, with storms moving from west to east parallel to the initiating theta-e gradient boundary. This could set the stage for thunderstorms that traverse the same areas repeatedly through the afternoon and evening.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1234 PM CDT Sun Jul 5 2026

VFR conditions prevail at all TAF sites this afternoon through Monday morning. Winds increase slowly this afternoon across eastern North Dakota, generally out of the south to southeast at 10-20 knots. Clear skies this afternoon will give way to some high clouds late this evening and overnight, however, VFR conditions are expected to continue. Isolated showers and thunderstorms are possible late this evening and overnight, primarily in the vicinity of KDVL, with little confidence in coverage. Heading further into Monday, there is a better chance for showers and thunderstorms that could bring impacts late in the TAF period.
