Valid 141200Z - 151200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
A few storms are possible across South Florida and the Florida Keys,
as well as the western Gulf Coast today.
...Discussion...
Strong upper trough over the Great Lakes/Midwest region will advance
off the Middle Atlantic Coast by 15/06z as the primary midlevel
speed max translate well downstream. Dominant surface anticyclone
will settle into the mid MS/OH Valley region by late afternoon which
will effectively drive the cold front deep into Mexico and across
the southern FL Peninsula. Early in the period, isolated
thunderstorms may be noted along the trailing cold front across the
northwestern Gulf Coast region. Some risk for a few flashes of
lighting are also possible with weak convection across the southern
FL Peninsula before flow veers and stronger convergence shifts
offshore.
