   Mesoscale Discussion 0822
   NWS Storm Prediction Center Norman OK
   0245 AM CDT Wed May 24 2017

   Areas affected...Northern Florida

   Concerning...Severe potential...Watch possible 

   Valid 240745Z - 240945Z

   Probability of Watch Issuance...40 percent

   SUMMARY...At least isolated thunderstorms remain possible this
   morning, a few of which could be severe with a brief tornado or wind
   threat. A watch could be considered if trends increase.

   DISCUSSION...Surface analysis shows a weak boundary across northern
   Florida, with slightly better theta-e to the south where
   temperatures remained in the upper 70s. A small broken line of
   thunderstorms has recently formed in this region, with signs of
   midlevel rotation. Substantial southwesterly flow aloft already
   exists across the region and this will increase today. As shear acts
   upon these cells, it is not inconceivable that one or two could
   become severe, with a brief tornado or wind threat.
