   Mesoscale Discussion 0823
   NWS Storm Prediction Center Norman OK
   0530 AM CDT Wed May 24 2017

   Areas affected...Much of central and northern Florida

   Concerning...Outlook upgrade 

   Valid 241030Z - 241230Z

   SUMMARY...Much of northern and central Florida will be upgraded to
   an Enhanced Risk at 13Z for potentially widespread damaging winds
   and a few tornadoes.

   DISCUSSION...Scattered storms are already increasing along a weak
   boundary across northern Florida, where low-level shear is a bit
   stronger. As the upper trough approaches, wind fields will increase
   markedly during the day, becoming more favorable for both wind
   damage and tornadoes, conditional on storm mode. A very moist and
   unstable air mass is already in place, and little heating will be
   necessary. Given lack of any CIN or cap, storms may form anywhere
   across the warm sector during the day, however, the main foci will
   be the aforementioned boundary over northern Florida, and with
   strong storms moving in off the Gulf of Mexico.

   In the short term, a tornado watch may be needed soon for parts of
   northern Florida.
