Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0758 PM CDT Fri Oct 23 2020
Valid 240100Z - 241200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
No severe weather threat is expected across the continental United
States this evening or tonight.
...DISCUSSION...
A line of thunderstorms is ongoing from northern Kentucky
north-northeastward across Ohio and into far northwest Pennsylvania.
There is a narrow corridor of weak instability just ahead of the
line with the RAP suggesting MLCAPE is generally around 400 J/kg or
less. As instability weakens further over the next hour or two, the
line is expected to be on the downtrend. For this reason, the severe
threat is expected to end shortly and a categorical risk area will
not be issued for this outlook.
Elsewhere across the continental United States, no severe weather
threat is expected through tonight.
