SEVERE WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FORT WORTH TX
1140 AM CST FRI APR 4 1997

THERE IS SLIGHT RISK OF SEVERE THUNDERSTORMS FOR ALL OF NORTH TEXAS
THIS AFTERNOON AND ACROSS MAINLY THE EASTERN TWO THIRDS TONIGHT.

A VIGOROUS UPPER LEVEL STORM WAS MOVING ACROSS THE ROCKIES AND WILL
DRIVE ACROSS ALL OF NORTH CENTRAL TEXAS BY LATE TONIGHT. A SURFACE
DRY LINE OVER WEST TEXAS AT MIDDAY WILL BE THE FOCUS FOR THE
DEVELOPMENT OF A LINE OF STRONG THUNDERSTORMS THIS AFTERNOON. THE DRY
LINE WILL MOVE INTO WESTERN PARTS OF NORTH TEXAS BY LATE AFTERNOON
AND WILL REACH THE DALLAS-FORT WORTH METROPLEX AND WACO DURING THE
EVENING HOURS. THE BOUNDARY WILL EVENTUALLY REACH EASTERN PARTS FROM
PARIS TO ATHENS TO CENTERVILLE AROUND MIDNIGHT.

AN ABUNDANCE OF DEEP TROPICAL MOISTURE REMAINS IN PLACE OVER THE
REGION. COLD AIR ALOFT AND SOME BREAKS IN THE CLOUD COVER LATER THIS
AFTERNOON WILL AID IN THE RAPID DESTABILIZATION OF THE ATMOSPHERE.
MOISTURE CONVERGENCE WILL BE MAXIMIZED ALONG THE DRY LINE WHERE THE
ERUPTION OF SCATTERED SEVERE THUNDERSTORMS ALONG AND IN ADVANCE OF
THE BOUNDARY WILL HAVE THE POTENTIAL TO PRODUCE LARGE HAIL AND
DAMAGING WINDS. A FEW SUPERCELL THUNDERSTORMS ARE EXPECTED MAINLY IN
THE WACO VICINITY WHERE AN ISOLATED TORNADO COULD BE OBSERVED.

ADDITIONAL HEAVY RAINFALL AMOUNTS OF 1 TO 2 INCHES WITH THE STRONGEST
THUNDERSTORMS WILL LIKELY COMPOUND THE FLASH FLOOD THREAT OVER THE
AREA. THE GROUND REMAINS AT OR NEAR SATURATION AT SEVERAL LOCATIONS
AND ANY ADDITIONAL HEAVY RAINS WILL RAPIDLY RUNOFF AND PRODUCE HIGH
WATER PROBLEMS.

A VERY TIGHT PRESSURE GRADIENT IS EXPECTED TO DEVELOP IN WAKE
OF THE DRY LINE BY LATE TONIGHT INTO SATURDAY. WEST TO SOUTHWEST
WINDS SATURDAY WILL INCREASE DRAMATICALLY ACROSS WESTERN AND CENTRAL
PARTS OF NORTH TEXAS WHERE SUSTAINED WINDS OF 20 TO 30 MPH WILL
OCCUR. HIGHER GUSTS UP TO 40 MPH ARE LIKELY SATURDAY.

EMERGENCY MANAGEMENT AND STORM SPOTTERS WEST OF A JACKSBORO...
STEPHENVILLE...TO WACO LINE SHOULD BE READY FOR SPOTTER ACTIVATION
THIS AFTERNOON. SPOTTERS FROM SHERMAN TO THE DALLAS-FORT WORTH
METROPLEX WILL LIKELY BE ACTIVATED DURING THE EVENING HOURS.
ELSEWHERE...SPOTTER ACTIVATION WILL BE LIKELY FROM LATE EVENING UNTIL
EARLY SATURDAY MORNING.

STAY TUNED TO NOAA WEATHER RADIO OR YOUR CABLE TELEVISION PROVIDER
FOR THE LATEST STATEMENTS FROM THE NATIONAL WEATHER SERVICE.
