Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
1143 PM CST Wed Dec 14 2022

Valid 171200Z - 181200Z

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

....SUMMARY...
Isolated showers or thunderstorms may occur over parts of Florida on
Saturday, but severe weather is unlikely.

....Synopsis...
The upper low over the Great Lakes will fill as it lift into the
Northeast through Sunday morning, and a trailing positive-tilt upper
trough sweeps eastward across the Southeast. To the west, a
shortwave trough is forecast to move across southern CA and toward
western AZ by 12Z Sunday.

At the surface, high pressure will remain from Great Basin into much
of the central/southern Plains and into the Southeast. A weak
surface trough is forecast to develop over the southern and eastern
Gulf of Mexico, extending across southern FL Saturday night.  A
modest increase in moisture may occur as the upper trough passes to
the north and surface winds veer to southerly, increasing dewpoints.
At any rate, instability will be quite weak, with only sporadic
convection expected.
