Valid 280100Z - 281200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated-to-scattered thunderstorm threat continues tonight.
...01z Update...
Weak MCS has evolved over the eastern Gulf/west-central FL Peninsula
early this evening. Latest radar data suggests an MCV may be
embedded within the broader precip shield over Hernando county, and
this feature is shifting steadily east. Greatest concentration of
convection this evening will likely be immediately ahead of this
feature, with a trailing band of somewhat stronger updrafts trailing
southwest across the Tampa region into the eastern Gulf. While this
trailing band may exhibit a bit more intensity, the threat of severe
remains low as poor midlevel lapse rates are likely inhibiting
updraft strength.
