MESOSCALE DISCUSSION 0160

NWS STORM PREDICTION CENTER NORMAN OK

0345 PM CST FRI FEB 24 2012

AREAS AFFECTED...ERN SC...CNTRL/ERN NC...SERN VA...SERN MD

CONCERNING...TORNADO WATCH 38...

VALID 242145Z - 242315Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 38 CONTINUES.

LATEST SFC MESOANALYSIS DEPICTS A NEARLY STATIONARY FRONT EXTENDING

ALONG THE SRN DE BORDER AND ACROSS SERN MD AND NRN VA...WITH A

SUBSYNOPTIC-SCALE LOW CENTERED ALONG THE STATIONARY FRONT NEAR THE

VA/MD BORDER. THE STATIONARY FRONT INTERSECTS A COLD FRONT AT A

TRIPLE POINT NEAR THE WV/VA BORDER...WHILE THE COLD FRONT TRAILS

SSWWD INTO THE WRN CAROLINAS. CONVERGENCE ALONG THE COLD FRONT AND A

PREFRONTAL TROUGH EXTENDING SW OF THE AFOREMENTIONED LOW HAS

SUPPORTED A BROKEN CONVECTIVE LINE FROM S-CNTRL VA TO CNTRL NC WITH

MORE ISOLATED STORMS FARTHER NE TOWARD THE LOW. THIS LINE IS

FORECAST TO TRANSLATE EWD ACROSS THE MARGINALLY UNSTABLE SECTOR

/AIDED BY EARLIER DIABATIC HEATING ASSOCIATED WITH

INSOLATION/...WITH THE STORMS LIKELY REACHING THE COAST AFTER 23Z.

AND...WITH 100 KT OF FLOW AROUND 5 KM AGL PER RALEIGH VWP...VERY

STRONG DEEP-LAYER SHEAR WILL CONTINUE TO SUSTAIN ORGANIZED

CONVECTIVE STRUCTURES TOWARD THE COAST DURING THE NEXT FEW HOURS.

EFFECTIVE SRH VALUES OF 300-400 M2/S2 WILL SUPPORT EMBEDDED

MESOVORTICES WITH LEWP STRUCTURES /AS INDICATED BY RALEIGH WSR-88D

DATA/ ALONG WITH ATTENDANT THREATS FOR SWATHS OF WIND DAMAGE AND

PERHAPS A FEW TORNADOES.

FARTHER SOUTH...INSTABILITY WILL BE SOMEWHAT LOWER OWING TO

PERSISTENT CLOUDS AND STRATIFORM PRECIPITATION ACROSS PORTIONS OF

ERN/SERN NC AND NERN SC WITHIN 40 MILES EITHER SIDE OF A LINE FROM

NEAR FLORENCE SC TO 35 MILES N OF CAPE HATTERAS. IN THIS

REGION...THE SVR THREAT MAY BE MITIGATED BY THE ABSENCE OF STEEPER

LOW-LEVEL LAPSE RATES DESPITE THE APPROACHING FRONTAL CONVERGENCE.

HOWEVER...FARTHER SOUTH INTO ERN SC...POCKETS OF MARGINALLY GREATER

INSTABILITY MAY BOLSTER THE SVR THREAT WITH STORMS CURRENTLY

APPROACHING FROM THE WSW.

WeatherNC - a while back you noted that our DP here in Smithfield was down to 55°, but it seems to have been reading low all day compared to surrounding areas. It only maxed out at 57, while points E & W were in the low-mid 60's most of the day. Maybe we've be in a dry channel all day, but it's sure felt plenty muggy, despite the wind.

Likely an error Solak, not sure but my best guess. If you look around at obs not just during this event but as of late, you will find discontinuity between near-by stations and suspect readings givens the obs around, <30-50 miles. Maybe the AWOS are in need of calibration....
