   Mesoscale Discussion 0100
   NWS Storm Prediction Center Norman OK
   0830 PM CST Sat Jan 21 2017

   Areas affected...A small portion of southeast Mississippi into
   central and southern Alabama and parts of the Florida Panhandle

   Concerning...Tornado Watch 17...

   Valid 220230Z - 220400Z

   The severe weather threat for Tornado Watch 17 continues.

   SUMMARY...Severe/tornado risk continues to expand across Tornado
   Watch 17.

   DISCUSSION...As the west-to-east surface warm front continues to
   shift slowly north across Mobile Bay and the Florida Panhandle, a
   very favorable supercell environment (as revealed by the 22/00Z LIX
   RAOB, and area VWPs) continues to support an increase in coverage
   and intensity of severe storms across the region.  While storms
   continue to increase across the southern half of Mississippi which
   will eventually spread into WW 17, the more immediate threat exists
   with cells farther south, shifting east-northeast out of the Florida
   Panhandle into adjacent southern Alabama.  The most significant
   storm is currently straddling the Escambia AL/Escambia FL county
   line, where a potentially tornadic circulation is evident on radar. 
   Expect convective coverage to increase northward across the watch
   over the next couple of hours, along with continued severe/tornado
   potential.
