MESOSCALE DISCUSSION 0144
NWS STORM PREDICTION CENTER NORMAN OK
1125 PM CST WED FEB 22 2012
AREAS AFFECTED...CNTRL NC...SRN VA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 230525Z - 230700Z
AN ISOLATED SEVERE THREAT ONGOING WITH A CONVECTIVE LINE IN WCNTRL
NC WILL LIKELY CONTINUE FOR A FEW MORE HOURS. HOWEVER...THE THREAT
SHOULD REMAIN ISOLATED AND WW ISSUANCE DOES NOT APPEAR LIKELY ATTM.
A NEARLY CONTINUOUS LINE OF THUNDERSTORMS IS ONGOING JUST AHEAD A
WELL-DEFINED SHORTWAVE TROUGH MOVING THROUGH THE SRN APPALACHIAN
MTNS. REGIONAL WSR-88D VWPS AND FORECAST SOUNDINGS OVER CNTRL NC
THIS EVENING SHOW VERY STRONG DEEP LAYER SHEAR WITH 0-6 KM SHEAR
AROUND 70 KT. THIS ALONG WITH AN EWD STORM MOTION OF 40 TO 50 KT IS
CREATING A WIND DAMAGE THREAT ALONG THE LEADING EDGE OF THE LINE.
ALTHOUGH...A GUST OF 46 KT WAS RECORDED EARLIER AT
GREENSBORO...OBSERVATIONS OVER THE LAST HALF HOUR SUGGEST WINDS WITH
THE LINE HAVE RECENTLY BEEN BELOW 40 KT SUGGESTING THE WIND DAMAGE
THREAT IS MARGINAL. THE ORIENTATION OF THE WIND FIELD PARALLEL TO
THE LINE AND THE WEAK INSTABILITY COULD BE RESULTING IN THE MARGINAL
THREAT. FOR THIS REASON...A WATCH IS NOT EXPECTED DURING THE
OVERNIGHT PERIOD.
