Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0742 PM CDT Sun Apr 23 2023

Valid 240100Z - 241200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not forecast the rest of tonight.

....01z Update...

Expansive MCS continues to propagate across the western Gulf Basin
in response to low-latitude short-wave trough that is ejecting
across this region. As a result, thunderstorm probabilities are very
low across most of the CONUS east of the Rockies, except for a small
portion of south FL for the next few hours. Isolated thunderstorms
are focused just inland of the southern FL Gulf Coast from near
Sarasota Springs to western Miami-Dade County. Low-level convergence
should weaken across interior south FL over the next few hours and
this activity should gradually weaken.

Otherwise, scattered weak convection has developed from eastern
WA/OR into portions of the Great Basin. This activity is developing
within strongly diffluent flow aloft where lapse rates are steep.
Additionally, at least two distinct short-wave troughs are
influencing this convection and isolated thunderstorms can be
expected across this portion of the interior west tonight,
especially this evening.
