Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0805 PM CDT Sun Jul 19 2026
Valid 200100Z - 201200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE DAKOTAS/UPPER MIDWEST...
...SUMMARY...
Scattered severe thunderstorms capable of large hail and wind gusts
will remain possible mainly across the Dakotas into Minnesota.
...Northern Plains/Upper Midwest...
Severe thunderstorms including some supercells will continue to
focus this evening across the Dakotas, primarily across
south-central/eastern North Dakota as well as north-central/eastern
South Dakota, while also expanding into parts of Minnesota tonight.
Bouts of large hail will remain possible along with severe-caliber
wind gusts. This will be as storms progress east-southeastward with
the primary moisture/instability axis, supported by an amplifying
shortwave trough over Saskatchewan toward Manitoba, and the
development of a modest-strength southwesterly low-level jet across
the Upper Midwest tonight.
...Carolinas/Mid-Atlantic States...
A few strong/locally severe storms could still occur this evening,
but overall storm intensifies are expected to continue to wane with
the loss of daytime heating.
