Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
0653 PM CST Mon Feb 22 2021

Valid 230100Z - 231200Z


A couple thunderstorms remain possible across portions of the
Florida Peninsula through tonight.

A cold front has moved offshore across much of the Mid Atlantic
Coastline, diminishing thunderstorm chances across the area. Farther
south across FL, a diffuse cold front continues to slowly sag
southward across central portions of the Peninsula. While the 00Z
TBW modified sounding samples up to 400 J/kg MUCAPE, weak
convergence has resulted in little thunderstorm development so far.
With the upper trough and associated surface lee trough ejecting out
into the Atlantic, away from the Florida Peninsula, deep-layer
ascent is expected to only weaken with time. As such, the general
thunder area across FL has been constricted to the immediate
vicinity of strongest low-level convergence with the cold front, and
where some buoyancy (albeit mediocre) remains in place.
