MESOSCALE DISCUSSION 0176
NWS STORM PREDICTION CENTER NORMAN OK
1104 PM CST THU MAR 03 2016
AREAS AFFECTED...NRN FL...FAR SE GA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 040504Z - 040730Z
PROBABILITY OF WATCH ISSUANCE...5 PERCENT
SUMMARY...A POTENTIAL FOR STRONG WIND GUSTS WILL CONTINUE FOR A FEW
MORE HOURS AS A LINE OF STORMS MOVES EWD ACROSS NRN FL. WW IS NOT
EXPECTED DUE TO THE MARGINAL NATURE OF THE THREAT.
DISCUSSION...LATEST SFC ANALYSIS SHOWS A COLD FRONT EXTENDING FROM
NEAR THE COAST OF SC SWWD INTO SRN GA AND THE FL PANHANDLE. A SOLID
LINE OF THUNDERSTORMS IS ONGOING ALONG THE FRONT WHERE LOW-LEVEL
CONVERGENCE IS MAXIMIZED. THE LINE IS BEING SUPPORTED BY LARGE-SCALE
ASCENT AHEAD OF A SHORTWAVE TROUGH OVER THE CNTRL GULF COAST STATES.
ALTHOUGH THERE IS MINIMAL INSTABILITY...A 50 TO 60 KT LOW TO
MID-LEVEL JET IS LOCATED JUST BEHIND THE LINE ACCORDING TO OBJECTIVE
ANALYSIS FIELDS. THIS IS PROVIDING SUPPORT FOR A MARGINAL WIND
DAMAGE THREAT. THE STRONG LOW-LEVEL FLOW COULD BE TRANSFERRED TO THE
SURFACE WITH THE MORE INTENSE PORTIONS OF THE LINE MAKING ISOLATED
WIND DAMAGE POSSIBLE AS THE LINE APPROACHES THE ATLANTIC COAST OF
NRN FL OVER THE NEXT FEW HOURS.
