...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Only isolated, weak thunderstorms will be possible over parts of
southern Florida on Friday.
...Synopsis and Discussion...
A substantial upper trough is forecast to be over the Mid Atlantic
on Friday, and will move quickly into the Northeast. To the west,
zonal flow will temporarily develop over the Plains as a weaker
upper trough moves across the Great Basin.
At the surface, a high over the MS Valley will shift east through
the period, resulting in stable conditions. However, it appears that
a cold front may remain over far southern FL during the day, where
weak instability will remain. Forecast soundings depict deep,
low-level easterlies with PWAT between 1.50-1.75". As such, daytime
heating may lead to isolated thunderstorms around the Miami area
where low-level convergence will be maximized. Both weak shear and
instability will preclude severe potential there.
Elsewhere, 60s F dewpoints will reach the middle and upper TX Coasts
by 12Z Saturday as southeasterly surface winds increase in advance
of the western trough. While a few thunderstorms may occur over the
western Gulf of Mexico late Saturday morning, the probability of
thunderstorms over land is currently low.
