AS THEY MOVE INTO THE MOUNTAINS AND ENCOUNTER WEAKER INSTABILITY.

RISK EXTENDED TO THE SWRN TX/MEXICO BORDER AS STORMS HAVE RECENTLY
BEEN DEVELOPING SOUTH OF THE BORDER. ENVIRONMENT IS FAVORABLE FOR

CONCERNING...SEVERE THUNDERSTORM WATCH 324...
VALID 222044Z - 222145Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 324
CONTINUES.
NUMEROUS THUNDERSTORMS ARE SPREADING EASTWARD ACROSS WW 324 AND WILL
APPROACH THE EASTERN EDGE OF THE WATCH IN THE NEXT 1-2 HOURS. A NEW
WW WILL BE CONSIDERED FOR A NARROW AXIS FROM WRN WV INTO WRN NC.
WIDESPREAD THUNDERSTORMS...INCLUDING SCATTERED SEVERE STORMS HAVE
BEEN OCCURRING THIS AFTERNOON OVER MUCH OF CENTRAL/EASTERN KY AND
TN. THESE STORMS WILL BE MOVING OUT OF THE WATCH IN THE NEXT COUPLE
OF HOURS...AND INTO THE HIGHER MOUNTAINS OF EASTERN TN AND WRN
WV/VA/NC. STRONG DAYTIME HEATING HAS OCCURRED OVER THIS
REGION...ALLOWING AIR MASS TO BECOME MODERATELY UNSTABLE. WHILE LOW
LEVEL FORCING MECHANISMS ARE QUITE WEAK...NUMEROUS OUTFLOWS FROM
STORMS TO THE WEST MAY CONTINUE TO PROMOTE INTENSE THUNDERSTORM
DEVELOPMENT FOR A FEW MORE HOURS. SUFFICIENT WESTERLY FLOW ALOFT
WILL MAINTAIN A RISK OF ORGANIZED MULTICELL OR OCCASIONAL SUPERCELL
STORMS CAPABLE OF HAIL AND DAMAGING WINDS.
