Areas affected...central through south Florida

Concerning...Tornado Watch 545...

Valid 282011Z - 282145Z

The severe weather threat for Tornado Watch 545 continues.

SUMMARY...Threat for a few strong to damaging wind gusts and a
couple of tornadoes will persist over central and south central FL
through about 23Z. An additional WW across south FL appears unlikely
at this time.

DISCUSSION...A broken line of storms including a few small
supercells continues moving east southeast through south central FL.
The VWP data from Melbourne show strong 0-6 km shear, but modest
low-level hodographs due to the unidirectional nature of the winds
in the 0-2 km layer. The atmosphere remains moderately unstable with
1500-2000 J/kg MLCAPE but with weak mid-level lapse rates. This
environment will continue to support some bowing and supercell
structures with isolated damaging wind and a couple of brief
tornadoes possible.=20

Farther south across south FL, vertical shear is weaker and is not
expected to undergo a more substantial increase until mid-evening
when the boundary layer will be less unstable. While a limited
severe threat cannot be ruled out across south FL, overall threat
does not appear sufficient to warrant an additional WW in the near
term.
