Mesoscale Discussion 0396
   NWS Storm Prediction Center Norman OK
   1210 PM CDT Sat Apr 18 2020

   Areas affected...portions of the FL east coast

   Concerning...Severe potential...Watch possible 

   Valid 181710Z - 181815Z

   Probability of Watch Issuance...40 percent

   SUMMARY...A couple of strong to locally severe thunderstorms are
   possible this afternoon near the coast.

   DISCUSSION...Radar/satellite mosaic shows a band of thunderstorms
   draped across central FL gradually moving east-southeastward toward
   the Lake Okeechobee vicinity.  Convection is developing over the
   northern part of the Everglades where temperatures have warmed into
   the upper 80s to lower 90s.  KAMX VAD data shows weak flow in the
   lowest 3 km AGL (at or below 15 kt) but high-level flow will be more
   than adequate for updraft venting/maintenance as storms gradually
   intensify this afternoon.  A few wet microbursts (gusts 40-60 mph),
   aided by steep 0-3 km lapse rates (in excess of 8 deg C/km), in
   addition to marginally severe hail, may accompany the strongest
   storms.
