AREAS AFFECTED...VA...NC

CONCERNING...TORNADO WATCH 7...

VALID 112114Z - 112215Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 7 CONTINUES.

SUMMARY...STRONG TO SEVERE STORMS ARE TRACKING QUICKLY EAST ACROSS
TORNADO WATCH 7 AT ABOUT 45-50KT. SEVERE WIND AND TORNADO/WATERSPOUT
THREAT WILL SPREAD EAST OF THE MOUTH OF CHESAPEAKE BAY IN THE NEXT
HOUR. TRAILING PORTIONS OF THE SQUALL LINE WILL TAKE A BIT LONGER TO
CLEAR EXTREME NERN NC AND ALBEMARLE SOUND.

DISCUSSION...NARROW CORRIDOR OF WARM AND SUFFICIENTLY UNSTABLE AIR
IS NOW CONFINED TO ALMOST THE IMMEDIATE COASTAL/TIDEWATER AREAS
AHEAD OF A POWERFUL UPPER TROUGH AND 110-115 KT MID-LEVEL JET WEST
OF THE APPALACHIAN MOUNTAINS. PRE-FRONTAL SQUALL LINE INCREASED IN
INTENSITY/VIGOR OVER NERN NC AND PARTS OF VA TIDEWATER AND AS LARGE
SCALE ASCENT INTERACTED WITH THE SOMEWHAT GREATER INSTABILITY IN THE
NARROW WARM SECTOR. AKQ VWP NOW SHOWS A SHARP WIND SHIFT WITH
DEEP-LAYER WLY FLOW OF 50-60KT EVIDENT AND THIS SURGE WILL HELP
SHIFT THE SQUALL LINE OFF THE VA CAPES IN THE NEXT HOUR OR SO.
TRAILING PORTION OF THE CONVECTIVE LINE WILL TAKE A BIT LONGER TO
CLEAR THE LAND AREA ACROSS NERN NC WHERE BOTH KINEMATIC AND
THERMODYNAMIC ENVIRONMENT SHOULD CONTINUE TO SUPPORT BOTH DAMAGING
WIND AND TORNADO THREATS FOR ANOTHER 1-2 HOURS.
