TEXAS/OKLAHOMA PANHANDLES THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE AMARILLO TX
100 PM CDT FRI JUN 18 1993

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS LATE THIS AFTERNOON...
EVENING AND TONIGHT ACROSS ALL OF THE TEXAS AND OKLAHOMA PANHANDLES.
THE SEVERE STORMS MAY CAUSE FLOODING RAINS OF ONE TO TWO INCHES PER
HOUR...LARGE HAIL UP TO 2 INCHES IN DIAMETER...DAMAGING WINDS OF 60
TO 80 MPH...AND ISOLATED TORNADOES.

MOIST AIR COMBINED WITH HEATING THIS AFTERNOON WILL PRODUCE VERY
UNSTABLE CONDITIONS ACROSS THE PANHANDLES.  THE LIFT NECESSARY TO
INITIATE STORMS WILL BE ALONG A DRYLINE MOVING EAST OUT OF NEW
MEXICO...AND ALONG SEVERAL OUTFLOW BOUNDARIES FROM OVERNIGHT STORMS.
ALSO...THE WINDS OVER THE PANHANDLES ARE CONDUCIVE FOR DEVELOPMENT OF
ROTATING SUPERCELL STORMS.

ANY SEVERE STORMS SHOULD DEVELOP AFTER 300 PM CDT THIS AFTERNOON AND
CONTINUE INTO THE EVENING HOURS.  OVERNIGHT THE MAIN THREAT FROM
STORMS WILL BE FLOODING RAINS.

SPOTTER GROUPS AND EMERGENCY MANAGEMENT OFFICIALS ACROSS THE OKLAHOMA
AND TEXAS PANHANDLES SHOULD REMAIN ALERT AND BE READY FOR ACTIVATION
