OKZ001>003-TXZ001>020-252300- TEXAS/OKLAHOMA PANHANDLES THUNDERSTORM OUTLOOK NATIONAL WEATHER SERVICE AMARILLO TX 101 PM CDT TUE MAY 25 1999 THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE TEXAS AND OKLAHOMA PANHANDLES THROUGH TONIGHT. A COLD FRONT WILL SLOWLY MOVE SOUTH ACROSS THE SOUTHERN TEXAS PANHANDLE LATE THIS AFTERNOON THROUGH THIS EVENING. COOL AND CLOUDY CONDITIONS ARE FOUND NORTH OF THE FRONT...WHILE SUNSHINE AND WARMER TEMPERATURES PREVAIL SOUTH OF THE FRONT. THE TEMPERATURE DIFFERENCE BETWEEN THESE TWO AIR MASSES WILL SET THE STAGE FOR THUNDERSTORM DEVELOPMENT LATE THIS AFTERNOON INTO THIS EVENING. THE MOST FAVORED AREA FOR SEVERE THUNDERSTORMS WILL BE ALONG AND JUST SOUTH OF THE COLD FRONT AS DAYTIME HEATING CREATES STRONG INSTABILITY. AN UPPER LEVEL LOW PRESSURE SYSTEM OVER ARIZONA WILL SEND AN UPPER AIR DISTURBANCE TOWARD THE PANHANDLES TONIGHT. THUNDERSTORMS SHOULD CONTINUE ACROSS THE REGION OVERNIGHT AS THE UPPER LEVEL DISTURBANCE STRENGTHENS THE WIND ALOFT. THE WIND ALOFT WILL ALSO BECOME MORE DIVERGENT WITH TIME TONIGHT WHICH COULD CAUSE A WIDESPREAD AREA OF THUNDERSTORMS TO BREAK OUT. THE MAIN SEVERE WEATHER THREAT FROM THUNDERSTORMS TONIGHT WILL BE LARGE HAIL AND STRONG DAMAGING WINDS. ISOLATED TORNADOES WILL ALSO BE POSSIBLE AS THE WIND ALOFT INCREASES AND STORMS MOVE OVER THE COLD FRONT AND OTHER OUTFLOW BOUNDARIES LEFT OVER FROM RECENT THUNDERSTORMS. HEAVY RAINFALL WILL ALSO BE POSSIBLE FROM THESE STORMS WHICH COULD CAUSE LOCALIZED FLOODING PROBLEMS. SPOTTER GROUPS AND EMERGENCY MANAGEMENT OFFICIALS MAY REQUIRE ACTIVATION LATE THIS AFTERNOON OR TONIGHT. GOEHRING
