...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms are possible across southeast Florida on
Thursday. Severe storms are not expected.

...Discussion...
A large, expansive mid-level ridge will be present across the
eastern CONUS on Thursday. Offshore flow will be present across the
entire eastern half of the CONUS as high pressure builds into the
Plains. This high pressure will expand a dry, continental polar
airmass which should keep any thunderstorm chances limited.

A few isolated thunderstorms are possible ahead of the front across
Florida, but weak instability and modest lapse rates should keep any
severe storm threat limited.

Significant temperature differences between the Great Lakes and the
cold airmass aloft should result in some instability in the Great
Lakes. Deeper convection that can develop over the lakes with some
graupel could result in a few lightning flashes given an EL around
-20C. However, given the mostly below freezing temperature profile,
the likelihood of mixed-phase elements remains uncertain and a
general thunderstorm line has not been included at this time.
