MESOSCALE DISCUSSION 0153

NWS STORM PREDICTION CENTER NORMAN OK

0949 AM CST FRI FEB 24 2012

AREAS AFFECTED...SRN AL...GA...WCNTRL SC

CONCERNING...TORNADO WATCH 35...

VALID 241549Z - 241645Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 35 CONTINUES.

A NARROW ZONE OF STRONGER BOUNDARY LAYER HEATING...ROUGHLY 50-75MI

WIDE...HAS DEVELOPED FROM THE WRN FL PANHANDLE...NEWD INTO CNTRL GA

BENEATH BREAKS IN CLOUD COVER. LOW LEVEL LAPSE RATES ARE STEEPENING

ALONG THIS CORRIDOR THOUGH LOWER TROPOSPHERIC FLOW HAS VEERED

SOMEWHAT. THIS HEATING WILL LIKELY TRANSLATE INTO A MORE UNSTABLE

ENVIRONMENT FOR INTENSE UPDRAFTS.

LATEST TRENDS SUGGEST CONVECTION IS BEGINNING TO INCREASE IN

INTENSITY ALONG THE SURGING COLD FRONT AS IT CATCHES UP TO THE

PRE-FRONTAL CONVECTION OVER AL. ENHANCED CONVERGENCE COULD EASILY

ENCOURAGE STRENGTHENING AND THERE IS INCREASING CONFIDENCE THAT

SEVERE THUNDERSTORMS WILL OVERSPREAD THE AFOREMENTIONED CORRIDOR OF

STRONGER HEATING. IT/S NOT ENTIRELY CLEAR HOW THE BAND OF

SHOWERS/ISOLATED THUNDERSTORMS WELL AHEAD OF THE FRONT OVER THE FL

PANHANDLE WILL EVOLVE. LATEST THINKING IS CONVECTION WILL LIKELY BE

MORE CONCENTRATED/INTENSE ALONG THE SURGING COLD FRONT.

MESOSCALE DISCUSSION 0154

NWS STORM PREDICTION CENTER NORMAN OK

1010 AM CST FRI FEB 24 2012

AREAS AFFECTED...SC...SRN NC

CONCERNING...TORNADO WATCH 35...

VALID 241610Z - 241715Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 35 CONTINUES.

NEWD EXTENSION OF PRE-FRONTAL TSTM BAND IS EXPANDING ACROSS SC

TOWARD SRN NC. ALONG THIS BAND INDIVIDUAL CELLS ARE INTENSIFYING

WITHIN STRONGLY SHEARED ENVIRONMENT. OVER THE LAST HOUR OR SO A FEW

NE-SW LINE SEGMENTS HAVE EVOLVED AND THESE SEGMENTS MAY BECOME MORE

EFFICIENT WIND PRODUCERS IF THEY CAN MAINTAIN A MORE PERPENDICULAR

ORIENTATION TO MEAN FLOW. GIVEN THEIR FAST MOVEMENT THE LEADING

ACTIVITY WILL SPREAD EAST OF WW35 INTO PORTIONS OF SERN SC/NC WITHIN

THE HOUR. WILL CONTINUE TO MONITOR THIS REGION FOR A POSSIBLE WW.

Nasty looking storm west of Troy, AL right now. Not seeing much on velocity however. Straight line winds are pretty high though.

Storms barely missed me- typical. .04 and a rumble of thunder, cold front just zipped by. Looks ominous for a big area east of here- should be a few nasty storms in the Carolinas and Mid-Atlantic.

Same up here but...no thunder and not a single drop from the front. Oh well...time to get cold.

Per the SPC:

THE THREAT FOR SVR STORMS WILL INCREASE ACROSS NERN SC...CNTRL/ERN

NC...ERN VA...AND SRN MD EARLY THIS AFTERNOON...AND A TORNADO WATCH

WILL LIKELY BE REQUIRED BETWEEN 18Z AND 19Z.

A WARM/UNSTABLE SECTOR WILL CONTINUE TO EXPAND NORTHWARD TOWARD NRN

VA AND SRN MD THIS AFTERNOON AHEAD OF A COLD FRONT CURRENTLY

CROSSING THE APPALACHIANS. CONVERGENCE ALONG THE FRONT AND

INCREASING PRE-FRONTAL LARGE-SCALE ASCENT -- INDICATED BY SFC

PRESSURE FALLS AROUND 2 MB PER 2 HRS -- WILL CONTINUE TO SUPPORT

CONVECTION BOTH ALONG AND AHEAD OF THE FRONT. A VERY STRONG

MID-LEVEL JET CORE CROSSING THE REGION WILL CONTRIBUTE TO EFFECTIVE

BULK SHEAR MAGNITUDES EXCEEDING 60 KT...WHICH WILL PROMOTE BANDS AND

CLUSTERS OF FAST-MOVING THUNDERSTORMS CAPABLE OF PRODUCING

WIDESPREAD DAMAGING WINDS. WITH 0-1-KM BULK SHEAR MAGNITUDES OF

30-45 KT...TORNADOES WILL BE POSSIBLE...PARTICULARLY IN ASSOCIATION

WITH ANY LEWP PATTERNS AND CONVECTION WELL IN ADVANCE OF THE FRONT

WHERE SFC WINDS ARE SOMEWHAT MORE BACKED RELATIVE TO THE WLY FLOW

ALOFT. UNCERTAINTY IN THE NRN EXTENT OF THE UNSTABLE SECTOR

EXISTS...AS WELL AS THE IMPACT OF MID/HIGH CLOUDS OVER CNTRL/ERN NC

AND NERN SC. HOWEVER...IN BOTH INSTANCES...INSTABILITY IS EXPECTED

TO BE SUFFICIENT...GIVEN THE MAGNITUDE OF FORCING FOR ASCENT...SUCH

THAT A SVR/TORNADO THREAT WILL LIKELY EVOLVE.

I'm at lunch (at work) here in Orangeburg, my son is freaking at home with his G'ma. Could someone please post a GR vel shot of the area as I'm getting reports that one has been spotted between Gaston and Swansea. TIA!

You mean the one that went south of Columbia earlier or the new warning just issued?
