SEVERE WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FORT WORTH TX
354 PM CDT SUN AUG 11 1996

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS TONIGHT FOR A LARGE
PART OF NORTH TEXAS. A FEW OF THE CITIES INCLUDED IN THE SLIGHT RISK
AREA ARE SHERMAN...PARIS...BONHAM...GREENVILLE...DENTON...MINERAL
WELLS...WEATHERFORD AND THE DALLAS-FORT WORTH METROPLEX.

A STRONG UPPER LEVEL DISTURBANCE AND AN ASSOCIATED COLD FRONT WILL
APPROACH FROM THE NORTHWEST EARLY TONIGHT AND RESULT IN A ROUND OF
THUNDERSTORMS. THUNDERSTORMS WERE ALREADY FIRING WITH THESE TWO
FEATURES OVER WESTERN OKLAHOMA AND UPPER LEVEL WINDS SUGGEST THESE
STORMS WILL CONTINUE TO DEVELOP AND MOVE SOUTHWARD TOWARD NORTH TEXAS
THIS EVENING.

ABUNDANT LOW LEVEL MOISTURE WITH A LAYER OF DRY AIR ALOFT WAS IN
PLACE ACROSS THE RISK AREA. THIS WOULD SUGGEST THE MAIN THREAT FROM
THESE STORMS WILL BE LARGE HAIL AND STRONG DOWNBURST WINDS. HOWEVER
....WIND PROFILES ACROSS THE NORTHERN PART OF THE RISK AREA...
ESPECIALLY ALONG THE RED RIVER...ARE BECOMING INCREASINGLY FAVORABLE
FOR SUPERCELL THUNDERSTORMS AND THUS A HIGHER THREAT FOR TORNADOES.

EMERGENCY MANAGEMENT OFFICIALS AND STORM SPOTTERS ACROSS THE RED
RIVER COUNTIES FROM MONTAGUE TO PARIS SHOULD BE READY FOR ACTIVATION
BY 8 PM...AREAS NORTH OF AN EASTLAND TO WAXAHACHIE TO CANTON LINE AND
INCLUDING THE DALLAS-FORT WORTH METROPLEX BETWEEN 10 PM AND MIDNIGHT.

CONTINUE TO MONITOR NOAA WEATHER RADIO OR YOUR LOCAL TV/RADIO STATION
FOR THE LATEST STATEMENTS CONCERNING THIS DEVELOPING SEVERE WEATHER
THREAT.
