   Mesoscale Discussion 0871
   NWS Storm Prediction Center Norman OK
   0241 PM CDT Sun Jun 07 2020

   Areas affected...northern Florida southern Georgia

   Concerning...Severe potential...Watch unlikely 

   Valid 071941Z - 072145Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Several miniature supercells associated with the rainbands
   of TS Cristobal may pose a brief tornado threat for the next few
   hours. A watch is likely not needed.

   DISCUSSION...As of 1 pm CDT The National Hurricane Center had
   Tropical Storm Cristobal located at Location: 28.8 N 89.9 W moving
   north at 5 mph. An exterior rainband of TS Cristobal is interacting
   with a differential heating zone across northern Florida. Recently,
   a few weak low-level mesocyclones have been observed with storms
   embedded in the precipitation band. These storms may pose a risk for
   a brief weak tornado given 0-1 km srh of 100-200 ms/s2. Some
   clearing ahead of the rainband and differential heating zone will
   allow weak instability of 500-100 J/kg of MLCAPE to support updrafts
   through this afternoon. Given the relatively brief and marginal
   nature of the threat, a watch is unlikely.
