....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected tonight.

....01z Update...

Early-evening water-vapor imagery depicts a mid-level short-wave
trough extending from the southern Appalachians, southwest into the
northeast Gulf of Mexico. Majority of convection has now shifted
offshore over the northeast Gulf Basin with lighting concentrated at
least 130 mi west of TPA. As the primary surface wave evolves off
the FL Atlantic Coast, deep convection should begin to focus east of
the Peninsula. Probability of strong convection is low across FL
this evening.

Upstream, a pronounced short-wave trough is ejecting across the Four
Corners region. Large-scale ascent will spread ahead of this feature
into the TX Panhandle later tonight. 00z sounding from AMA was quite
dry but exhibited very steep lapse rates. Mid-level moistening into
this environment may provide adequate buoyancy for a few flashes of
lightning; however, any thunderstorms will remain very sparse.
