   Valid 192000Z - 201200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Potential for an isolated thunderstorm or two persists along the
   coast of southeast Florida.

   ...Discussion...
   No changes appear necessary to the ongoing outlook at this time.  A
   few lightning flashes may eventually occur with convection moving
   eastward across southeastern Florida at this time, and an additional
   flash or two may occur with convective snow bands across portions of
   the Northeast.  Otherwise, thunderstorms are not expected the rest
   of the period.

   .PREV DISCUSSION... /ISSUED 0957 AM CST Sat Feb 19 2022/

   ...FL...
   A surface cold front extends across central FL today, and will push
   southward and offshore after dark.  Convergence along the boundary
   is weak, and surface winds ahead of the front have veered to
   northwesterly.  Nevertheless, ample low-level moisture is present in
   the pre-frontal air mass, with pockets of daytime heating expected. 
   This may result in an isolated thunderstorm or two along the
   immediate coastline in vicinity of Miami.  This threat should
   diminish by early evening as the front moves through and diurnal
   cooling commences.

   Elsewhere, very isolated lightning flashes will be possible today
   along a band of shallow convective snow squalls moving through
   NY/PA.  This threat will remain below 10% coverage.
