TEXAS/OKLAHOMA PANHANDLES THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE AMARILLO TX
1227 PM CDT FRI MAY 31 1996

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS THE
EASTERN HALF OF THE OKLAHOMA AND TEXAS PANHANDLES.  THERE IS A
SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE REST OF THE
PANHANDLES.

THE MODERATE RISK AREA IS ALONG AND EAST OF A LINE FROM GUYMON
OKLAHOMA TO AMARILLO TEXAS.

A LOW LEVEL MOIST FLOW WILL CONTINUE ACROSS THE PANHANDLES
THROUGH TONIGHT.  THIS LOW LEVEL MOISTURE COMBINED WITH SURFACE
HEATING THIS AFTERNOON AND COLD AIR ALOFT WILL SET THE STAGE FOR
THUNDERSTORM DEVELOPMENT.  A DRYLINE WILL ALSO PROVIDE LIFT FOR
THE THUNDERSTORMS...ESPECIALLY ACROSS THE EASTERN PARTS OF THE
PANHANDLES.

THE MAIN SEVERE THREAT FROM ANY THUNDERSTORMS THAT FORM WILL BE
LARGE HAIL AND DAMAGING WINDS.  THE WIND PROFILE WILL ALSO BECOME
MORE FAVORABLE FOR TORNADO DEVELOPMENT AS THE DAY WEARS ON AS AN
UPPER LEVEL DISTURBANCE MOVES ACROSS.

EMERGENCY MANAGEMENT PERSONNEL AND SPOTTERS WILL WANT TO REMAIN
ALERT FOR POSSIBLE ACTIVATION THIS AFTERNOON AND EVENING.
