WEST CENTRAL TEXAS HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE SAN ANGELO TX
735 AM CDT MON MAY 27 2002

...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS THE BIG
COUNTRY AND A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE
REMAINDER OF WEST CENTRAL TEXAS THIS AFTERNOON AND TONIGHT...

A MOIST AND UNSTABLE AIRMASS REMAINS IN PLACE ACROSS WEST CENTRAL
TEXAS. THIS COMBINED WITH AN UPPER LEVEL DISTURBANCE MOVING OUT OF
NEW MEXICO AND ACROSS THE TEXAS PANHANDLE WILL SET THE STAGE FOR
THUNDERSTORM DEVELOPMENT LATER THIS AFTERNOON AND WELL INTO THE
NIGHT. ALTHOUGH SEVERE THUNDERSTORMS WILL BE POSSIBLE ACROSS ALL OF
THE AREA TODAY...THE GREATEST POTENTIAL WILL ONCE AGAIN BE ACROSS THE
BIG COUNTRY AND NORTHERN CONCHO VALLEY WHERE THE INTERSECTION OF THE
DRYLINE AND A WEAK WARM FRONT WILL COMBINE TO HELP FOCUS
THUNDERSTORM DEVELOPMENT. THE PRIMARY THREATS WILL BE LARGE HAIL AND
DAMAGING WINDS ACROSS THE ENTIRE AREA. THERE IS ALSO THE POSSIBILITY
OF A TORNADO OR TWO IN THE NORTHERN PORTIONS OF THE CONCHO VALLEY
AND ESPECIALLY OVER THE BIG COUNTRY...WHERE BETTER WIND SHEAR WILL
PROFILE WILL BE IN PLACE NORTH OF A NEARLY STATIONARY BOUNDARY. IN
ADDITION WITH ALL OF THE RAIN THAT HAS FALLEN ACROSS THE NORTHERN
SECTIONS OF THE CONCHO VALLEY AND THE BIG COUNTRY THE PAST SEVERAL
DAYS...THERE IS A CHANCE THAT FLASH FLOODING COULD BECOME A THREAT
AS THESE THUNDERSTORMS WILL LIKELY DROP AN INCH OR TWO OF RAIN IN A
SHORT PERIOD OF TIME.

SPOTTER ACTIVATION MAY BE NEEDED ACROSS WEST CENTRAL TEXAS
TODAY...ESPECIALLY ACROSS THE BIG COUNTRY AND NORTHERN CONCHO VALLEY.

FOR ADDITIONAL INFORMATION PLEASE SEE STATEMENTS AND OUTLOOKS FROM
NATIONAL WEATHER SERVICE OFFICES ACROSS TEXAS...OKLAHOMA...AND NEW
MEXICO.
