DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1126 AM CST TUE NOV 25 2014

VALID 261200Z - 271200Z

...NO SVR TSTM AREAS FORECAST...

...SUMMARY...
A FEW THUNDERSTORMS WILL BE POSSIBLE ACROSS THE SOUTHERN FLORIDA
PENINSULA AND THE NORTH CAROLINA OUTER BANKS EARLY WEDNESDAY. NO
SEVERE STORMS ARE EXPECTED.

...SYNOPSIS...

SHORTWAVE TROUGH CURRENTLY OVER TX WITHIN BASE OF A SYNOPTIC TROUGH
WILL BE LOCATED OVER THE SERN STATES EARLY WEDNESDAY. THIS FEATURE
WILL SUBSEQUENTLY MOVE NEWD THROUGH THE MID-ATLANTIC DURING THE DAY
BEFORE REACHING THE NERN U.S. LATER WEDNESDAY NIGHT. A SFC LOW WILL
DEVELOP ALONG A FRONT LOCATED OFF THE COASTAL CAROLINAS AND DEEPEN
AS IT CONTINUES NWD ALONG THE MID-ATLANTIC AND NERN U.S. COASTS IN
RESPONSE TO FORCING FOR ASCENT ACCOMPANYING THE EJECTING SHORTWAVE
TROUGH. THE SRN EXTENSION OF THIS FRONT WILL ADVANCE THROUGH THE
REMAINDER OF THE SRN FL PENINSULA LATER WEDNESDAY MORNING.

...NC OUTER BANKS...

CURRENT INDICATIONS ARE THE WARM SECTOR WILL REMAIN OFFSHORE...BUT
THERE IS SOME CHANCE A VERY SMALL WARM SECTOR COULD MOVE ONTO THE
OUTER BANKS OF NORTH CAROLINA NEAR CAPE HATTERAS IN ADVANCE OF THE
DEEPENING SFC LOW. IN EITHER CASE...WIDESPREAD RAIN AND SHALLOW
CONVECTION WILL BE ONGOING WITHIN ZONE OF DEEPER ASCENT WEST OF THE
STALLED FRONT. HOWEVER...THE UNSTABLE LAYER MAY BE SUFFICIENT FOR A
FEW LIGHTNING STRIKES IN CLOSER PROXIMITY TO THIS BOUNDARY ALONG A
PORTION OF THE OUTER BANKS DURING THE MORNING HOURS.

...SRN FL...

A SMALL PRE-FRONTAL WARM SECTOR WITH WEAK INSTABILITY WILL EXIST
OVER SRN FL AT THE START OF THIS PERIOD. SHOWERS AND POSSIBLY A FEW
THUNDERSTORMS MAY BE ONGOING IN VICINITY OF THE COLD FRONT.
HOWEVER...ANY THUNDERSTORMS SHOULD END BY LATE MORNING AS THE FRONT
CONTINUES RAPIDLY SEWD AND OFFSHORE.
