   Areas affected...Florida Gulf Coast and vicinity

   Concerning...Severe potential...Tornado Watch likely 

   Valid 070440Z - 070645Z

   Probability of Watch Issuance...80 percent

   SUMMARY...Supercells are developing off the western Florida coast
   and are beginning to move onshore. Brief tornadoes and strong wind
   gusts are possible with these storms overnight. A watch issuance is
   likely.

   DISCUSSION...Rotating storms will continue to develop and move
   north-northeast over the eastern Gulf of Mexico tonight with some
   storms moving onshore. VROT on the convective cells have been
   somewhere between 10-25 knots indicating brief, weak tornadoes are
   possible. SRH 0-1 km is 100-250 m2/s2 per mesoanalysis and 00z TBW
   and TLH soundings. There is some uncertainty about supercell
   development offshore from southwest Florida, but from around Fort
   Myers towards Tallahassee along/near the Florida Gulf Coast is the
   most likely corridor for tornadoes and strong wind gusts.
