Day 2 Convective Outlook  

NWS Storm Prediction Center Norman OK

1243 AM CDT Thu Aug 20 2026



Valid 211200Z - 221200Z



...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER MUCH OF

NEBRASKA AND INTO NORTHERN KANSAS...



...SUMMARY...

Scattered damaging hail (some greater than 2 inch diameter) and

severe wind gusts may occur over parts of the central Plains late

Friday afternoon and evening. Scattered storms, some with severe

wind gusts, are possible Friday afternoon over parts of the

Carolinas and Georgia.



...NE into northern KS...

Moderate northwest flow aloft will develop over the northern to

central Plains on Friday, as a surface trough develops over the High

Plains. This will result in directional shear with elongated

hodographs featuring 50 kt effective deep-layer shear. Storms are

expected to develop near the low-level lapse rate plume during the

late afternoon over central to western NE, with cells moving

southeastward into the mid 60s F dewpoints and producing very large

hail. Isolated significant wind gusts may also occur if

storms/outflows merge, possibly extending into northern KS during

the evening. Overall storm coverage is uncertain, but at least

scattered cells appear likely, with high conditional risk of severe

hail/wind.



...Carolinas...GA...

A very moist and unstable air mass is forecast over the region on

Friday, near a surface trough and south of a cold front pushing into

NC. Numerous storms are forecast to develop after 20Z, within a weak

shear/strong instability environment. MLCAPE is forecast to be over

3000 J/kg, supporting vigorous updrafts and locally severe

microbursts and outflows.
