...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS FAR SOUTH
FLORIDA...

...SUMMARY...
A few strong thunderstorms may occur across the southern Florida
Peninsula and Keys this morning.

...Synopsis...
Strengthening mid-level flow remains across the lower 48 states with
an amplifying trough noted across the Appalachians and southeastern
US. An associated  cold front extending from the trough was draped
across southern Florida. To the west, high pressure across the
Rockies and Great Basin will flank an upper low moving south along
the California coast. With the exception of south Florida, a dry and
stable air mass will negate thunderstorm chances across the US. 

...Florida Keys and far southern Florida Peninsula...
To the south and east of the cold front, a warm, moist, and weakly
unstable air mass (dewpoints near 70F and MLCAPE of 250-750 J/kg)
will reside across the southern Peninsula. Model guidance indicates
a broken convective line across south Florida this morning, with it
exiting to the east by mid to late morning. Appreciably strong
low-level flow may support a few storms capable of damaging wind
gusts.
