...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast tonight.
...01z Update...
Thunderstorm potential is diminishing quickly across the FL
Peninsula early this evening. Boundary layer cooling will lead to
weaker buoyancy over the next few hours and poor lapse rates do not
appear particularly favorable for robust deep convection. Latest
radar data exhibits shallow convection along the front, but only a
few flashes of lightning remain with this activity.
Across the upper MS Valley, exit region of strong midlevel jet will
support weak elevated convection from eastern ND across MN into
western WI tonight. Warm advection and steep lapse rates should aid
the potential for at least a few flashes of lightning within the
stronger updrafts. Even so, thunderstorms will remain quite
isolated.
