SCATTERED THUNDERSTORMS OVER THE REGION. INITIAL DEVELOPMENT OF
THUNDERSTORM ACTIVITY IS EXPECTED OVER THE MOUNTAINOUS TERRAIN
AND THE HIGH PLAINS OF WEST TEXAS AND SOUTHEAST NEW MEXICO THIS
AFTERNOON. NORTHWEST FLOW ALOFT SHOULD PUSH GENERAL STORM MOVEMENT TO
THE SOUTHEAST...HOWEVER OUTFLOW BOUNDARY INTERACTIONS BETWEEN STORMS
MAY DIRECT MOVEMENT ELSEWHERE ON SOME STORMS. WIND PROFILES AT
LOWER LEVELS SUGGEST SUPERCELL FORMATION MAY BE POSSIBLE WITH SOME
STORMS.

THE MAIN THREAT WITH ANY STORMS THAT DO BECOME SEVERE WILL BE LARGE
HAIL UP TO 2 INCHES...AND WIND GUSTS TO 65 MPM ALONG WITH HEAVY
RAINS.

SPOTTER ACTIVATION MAY BE REQUIRED LATER THIS AFTERNOON.
