MESOSCALE DISCUSSION 0284
   NWS STORM PREDICTION CENTER NORMAN OK
   0223 AM CDT TUE MAR 19 2013
   
   AREAS AFFECTED...FL PANHANDLE/FAR SOUTHERN GA
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 190723Z - 190900Z
   
   PROBABILITY OF WATCH ISSUANCE...20 PERCENT
   
   SUMMARY...IN ASSOCIATION WITH A FAST-MOVING MCS...STRONG/MARGINALLY
   SEVERE WIND GUSTS AND/OR SOME HAIL WILL REMAIN POSSIBLE ACROSS THE
   FL PANHANDLE/FAR SOUTHERN GA THROUGH 09Z-10Z.
   
   DISCUSSION...A FAST-MOVING MCS CONTINUES TO STEADILY PROGRESS
   EAST-SOUTHEASTWARD AT AROUND 50 KT...EXTENDING FROM NEAR THE
   AL/GA/FL BORDER VICINITY SOUTHWESTWARD ACROSS THE WESTERN FL
   PANHANDLE AS OF 0715Z. THIS MCS IS FAVORING THE COOL SIDE OF AN
   OUTFLOW BOUNDARY /NOW OVER THE NORTHEAST GOM AND NORTH-CENTRAL FL
   PENINSULA/...WHICH MAY STILL BE AS MUCH AS 0.5-1KM AGL DEEP PER
   TALLAHASSEE WSR-88D VWP DATA. THE MOST SUSTAINED/ORGANIZED PORTION
   OF THE LINE SHOULD CONTINUE TO PREFERENTIALLY FAVOR THE IMMEDIATE
   COOL SIDE OF THE BOUNDARY ACROSS THE FL PANHANDLE IN CLOSER
   PROXIMITY TO SLIGHTLY ELEVATED MOIST/UNSTABLE INFLOW. WHILE A
   RELATIVELY FAST-MOVING/ORGANIZED MCS MAY BE MAINTAINED
   EAST-SOUTHEASTWARD OVER THE NEXT FEW HOURS /THROUGH 09Z-10Z/...THE
   RESIDUAL LOW-LEVEL STABILITY WILL TEND TO HINDER SEVERE-CALIBER WIND
   GUSTS. OTHERWISE...SOME HAIL MAY ALSO BE POSSIBLE IMMEDIATELY AHEAD
   OF THE CONVECTIVE LINE AND/OR ON ITS SOUTHERNMOST FLANK...BUT THIS
   POTENTIAL SHOULD ALSO REMAIN TEMPERED. IN ALL...THE SEVERE THREAT IS
   EXPECTED TO REMAIN MARGINAL...SUCH A WATCH IS NOT CURRENTLY
   ANTICIPATED.
