Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
0740 PM CDT Mon Oct 26 2020

Valid 270100Z - 271200Z


Organized severe thunderstorms are not expected across the
contiguous U.S. through tonight.

...01z Update...

Minor changes have been made to the 20z outlook this evening, namely
to lower thunder probabilities across most of the FL Peninsula.
Earlier convection that developed across the southwestern portions
of the Peninsula have propagated northwest with most lightning now
offshore. 01z product will reflect this evolution.

Farther west across the south-central US, isentropic ascent atop
cold boundary layer will be the primary forcing mechanism for
elevated convection later tonight. Earlier thunderstorm activity
that developed across the southern Plains has moved into the Ozark
Plateau region and weakened with minimal lightning observed.
However, buoyancy remains across the southern Plains and the next
short-wave trough will approach this region after midnight. At that
time, renewed thunderstorm activity is expected.
