   NWS STORM PREDICTION CENTER NORMAN OK
   1119 AM CST WED FEB 12 2014

   VALID 131200Z - 141200Z

   ...NO SVR TSTM AREAS FORECAST...

   ...SYNOPSIS...
   A RAPIDLY DEEPENING CYCLONE IS FORECAST TO DEVELOP NNEWD FROM
   EXTREME ERN NC AT THE BEGINNING OF THE PERIOD TO THE GULF OF MAINE
   BY THE END OF THE PERIOD.  A ZONE OF STRONG/DEEP FORCING FOR ASCENT
   WILL PRECEDE THE DEEPENING CYCLONE FROM THE MID ATLANTIC REGION INTO
   NEW ENGLAND TOMORROW...WITH WIDESPREAD FREEZING/FROZEN PRECIPITATION
   EXPECTED INLAND FROM THE COAST...AND A MIX WITH RAIN ALONG THE
   COAST.  MIDLEVEL LAPSE RATES NEAR 7 C/KM IMPINGING ON THIS ZONE OF
   ASCENT /DRIVEN BY LOW-LEVEL WAA/FRONTOGENESIS AND DCVA ALOFT/ WILL
   SUPPORT SOME EMBEDDED CONVECTIVE ELEMENTS AND POTENTIALLY A FEW
   LIGHTNING STRIKES FROM THE IMMEDIATE MID ATLANTIC COAST TOMORROW
   INTO SE NEW ENGLAND TOMORROW EVENING.  VERY ISOLATED LIGHTNING
   STRIKES CANNOT BE RULED OUT WITHIN THE DEFORMATION ZONE INVOF
   CENTRAL VA...THOUGH THIS RISK APPEARS TOO MARGINAL TO WARRANT AN
   OUTLOOK AREA.  FARTHER S... THE TRAILING COLD FRONT WILL MOVE ACROSS
   THE REMAINDER OF SE FL DURING THE FIRST HALF OF THE DAY...WITH
   ISOLATED THUNDERSTORMS POSSIBLE PRIOR TO FRONTAL PASSAGE.

   OTHERWISE...THE REMAINDER OF THE CONUS WILL BE DOMINATED BY
   RELATIVELY DRY/STABLE PROFILES WITH NO RISK FOR THUNDERSTORMS.  THE
   ONLY POSSIBLE EXCEPTION WILL BE ALONG PAC NW COAST WHERE A
   PRONOUNCED SHORTWAVE TROUGH WILL APPROACH WA/ORE LATE IN THE PERIOD.
   HOWEVER...ANY LINGERING SHALLOW BUOYANCY ALONG THE COAST TOMORROW
   WILL LIKELY BE OFFSET BY A TENDENCY FOR WAA AND HEIGHT RISES DURING
   THE DAY...PRIOR TO THE ARRIVAL OF THE SHORTWAVE TROUGH ON DAY 3.
