Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0739 PM CDT Thu Oct 01 2026
Valid 020100Z - 021200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected the remainder tonight into
early Friday.
...01z Update...
Severe probabilities have been removed from northwest OK/southwest
KS. Instability has largely diminished with loss of daytime heating
and in the wake of a surface cold front. Ahead of the front,
instability will continue to diminish, along with deep-layer flow,
while nocturnal cooling promotes increasing low-level inhibition.
This should largely preclude severe thunderstorm potential the
remainder of the forecast period.
