AREA THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE LUBBOCK TX
1205 PM CDT FRI MAY 24 2002

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS THE
SOUTHEASTERN PANHANDLE AND THE LOW ROLLING PLAINS. THIS AREA
IS NEAR AND EAST OF A BRICE TO MATADOR TO ASPERMONT LINE.

THERE IS A SLIGHT RISK A SEVERE THUNDERSTORMS ACROSS THE CENTRAL
SOUTH PLAINS AND PORTIONS OF THE SOUTHERN PANHANDLE. THIS AREA IS
NEAR AND EAST OF A DIMMITT TO TAHOKA LINE.

LATE THIS MORNING A COLD FRONT WAS LOCATED ACROSS THE TEXAS
PANHANDLE NEAR A LINE FROM TUCUMCARI NEW MEXICO TO AMARILLO TO GAGE
OKLAHOMA. A TROUGH OF LOW PRESSURE WAS LOCATED FROM NEAR A QUITAQUE
TO TAHOKA LINE. THIS TROUGH WILL LIKELY BECOME THE EASTERN EXTENT OF
THE DRYLINE LATER THIS AFTERNOON. IN ADDITION...A LOW PRESSURE CENTER
IS EXPECTED TO STRENGTHEN SOMEWHERE BETWEEN LUBBOCK AND CHILDRESS
THIS AFTERNOON...STALLING THE PROGRESS OF THE FRONT AND KEEPING A
GOOD AMOUNT OF MOISTURE ACROSS THE LOW ROLLING PLAINS. FINALLY...A
STRONG UPPER LEVEL STORM SYSTEM MOVING ACROSS THE ROCKIES INTO THE
CENTRAL PLAINS WILL ENHANCE THE POSSIBILITY OF THUNDERSTORM
DEVELOPMENT.

THE BEST CHANCE FOR THUNDERSTORMS WILL BE ACROSS THE SOUTHEASTERN
PANHANDLE WHERE THE CONVERGENCE OF LOW LEVEL WINDS AND THE AMOUNT OF
LOW LEVEL MOISTURE WILL BE MAXIMIZED. ADDITIONAL THUNDERSTORM
DEVELOPMENT WILL BE POSSIBLE FURTHER SOUTH ALONG THE DRYLINE. EAST OF
THE DRYLINE...LOW LEVEL WINDS ARE EXPECTED TO REMAIN SOUTHEAST TO
SOUTH WHILE ATMOSPHERIC INSTABILITY WILL BE VERY HIGH. THESE FACTORS
WILL CONTRIBUTE TO THE LIKELIHOOD OF SEVERE WEATHER...INCLUDING LARGE
HAIL...DAMAGING WINDS AND POSSIBLY ISOLATED TORNADOES.

FURTHER WEST...ENOUGH MOISTURE AND INSTABILITY MAY BE PRESENT ALONG
OR BEHIND THE SOUTHWARD MOVING COLD FRONT LATER THIS EVENING FOR
THUNDERSTORM DEVELOPMENT ACROSS THE NORTHERN SOUTH PLAINS OR
SOUTHERN PANHANDLE. IF STORMS FORM IN THIS AREA...THEY ALSO WILL
HAVE SOME POTENTIAL FOR PRODUCING LARGE HAIL AND DAMAGING WINDS.
THESE THUNDERSTORMS WOULD MOVE SOUTH WITH THE FRONT EXPANDING THE
SEVERE POTENTIAL SOUTHWARD INTO THE SOUTH CENTRAL SOUTH PLAINS.

SPOTTER ACTIVATION WILL BE LIKELY THIS AFTERNOON AND TONIGHT.
