SEVERE WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FORT WORTH TX
305 PM CDT MON MAY 14 1990

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THE REMAINDER OF
THIS AFTERNOON AND EVENING OVER THE NORTHWEST HALF OF NORTH TEXAS.
THE SLIGHT RISK AREA IS GENERALLY WEST OF A LINE THROUGH GAINESVILLE...
MINERAL WELLS... AND SAN ANGELO.

THUNDERSTORMS WERE BEGINNING TO DEVELOP AT 300 PM FROM WEST OF
CHILDRESS TO BETWEEN ABILENE AND LUBBOCK... OR ALONG THE DRY LINE.
TEMPERATURES IN THIS AREA HAD SOARED INTO THE 90S AT 300 PM... WITH
LUBBOCK AT 93 AND MIDLAND AT 97. THESE WARM TEMPERATURES
WERE OCCURRING IN THE CLEAR AIR NEAR THE DRY LINE... AND
COMBINED WITH THE HIGH VALUES OF LOW LEVEL MOISTURE EAST OF THE
DRIER AIR...WERE PRODUCING LIFTED INDEX VALUES... A MEASURE OF
INSTABILITY... INTO THE MINUS 14 TO MINUS 16 RANGE. THESE VALUES
ARE CONSIDERED TO BE VERY UNSTABLE... SO ANY THUNDERSTORMS THAT
DO DEVELOP IN THIS UNSTABLE AIR WILL LIKELY BECOME SEVERE VERY
QUICKLY. THIS WILL LIKELY OCCUR BEFORE 500 PM.

SOME HIGH BASED SHOWERS AND THUNDERSTORMS THAT HAVE PERSISTED ALL
DAY FROM MINERAL WELLAS TO WICHITA FALLS WERE NOT WELL ORGANIZED
BUT WERE KEEPING SURFACE TEMPERATURES DOWN IN THAT AREA. THIS
WAS KEEPING THE AIR TEMPORARILY MORE STABLE BETWEEN MINERAL WELLS
AND WICHITA FALLS... BUT THE RESULTING TEMPERATURES CONTRASTS
BETWEEN THIS AREA AND THE WARMER AIR TO THE WEST MAY EVENTUALLY
ENHANCE THUNDERSTORM DEVELOPMENT IN THAT AREA THIS AFTERNOON DUE
TO INCREASED LOW LEVEL WIND CONVERGENCE.

ANOTHER AREA WHERE SEVERE THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON
AND EVENING IS OVER NORTH CENTRAL AND NORTHEAST OKLAHOMA... WHERE
A RAIN-COOLED BOUNDARY INTERSECTED A COLD FRONT.

SPOTTERS AND EMERGENCY MANAGEMENT OFFICIALS WILL WANT TO KEEP IN
TOUCH WITH LATER WEATHER DEVELOPMENTS THE REMAINDER OF THIS AFTENOON
AND EVENING. THUNDERSTORMS WILL MOVE EAST-NORTHEAST WITH THE UPPER
LEVEL FLOW... BUTJ WILL TEND TO DIMINISH A FEW HOURS AFTER SUNSET
SINCE THE UPPER LEVEL SUPPORT IS MINIMAL.
