Day 2 Convective Outlook  

NWS Storm Prediction Center Norman OK

1145 AM CDT Sat Apr 20 2024



Valid 211200Z - 221200Z



...NO SEVERE THUNDERSTORM AREAS FORECAST...



...SUMMARY...

Isolated thunderstorms will be possible on Sunday across parts of

the Gulf Coast region, but no severe threat is expected.



...Synopsis and Discussion...

On Sunday, an elongated positive-tilt trough will gradually deepen

as it moves from the OH/Mid MS/Lower MO Valleys into the TN Valley

and coastal Southeastern states, providing gradual cooling aloft.



At the surface, a large area of high pressure will be centered over

the central Plains, with northerly winds over the western Gulf of

Mexico and drying into the Southeast and Mid Atlantic behind a

front. This front will extend from just off the coastal Carolinas

into southern GA and the FL Panhandle, with a moist air mass to the

south. 



Modest theta-e advection will occur near the cold front over FL and

GA, with gradual midlevel moistening. Lift for thunderstorms will be

focused mainly north of the boundary, as capping will exist south.

Weak instability will support scattered thunderstorms, but severe

weather is unlikely with poor lapse rates and weak lift.
