PUBLIC SEVERE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0104 PM CDT SUN JUN 03 2007

...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE SOUTHERN PLAINS
THIS AFTERNOON AND TONIGHT...

THE NWS STORM PREDICTION CENTER IN NORMAN OK IS EXPECTING THE
DEVELOPMENT OF LARGE HAIL...AND DAMAGING WINDS OVER PARTS OF THE
SOUTHERN PLAINS THIS AFTERNOON AND TONIGHT.

THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE

EXTREME SOUTHEAST NEW MEXICO
SOUTHWEST AND CENTRAL TEXAS

SURROUNDING THE MODERATE RISK AREA...THERE IS A SLIGHT RISK OF
SEVERE THUNDERSTORMS FROM THE SOUTHERN HIGH PLAINS EASTWARD INTO
PARTS OF THE SABINE RIVER VALLEY OF WESTERN LOUISIANA

NOCTURNAL THUNDERSTORM COMPLEX THAT TRAVELED ACROSS NORTHERN AND
EASTERN TEXAS THIS MORNING LEFT A BOUNDARY THAT HAS STALLED ALONG A
MIDLAND...BROWNWOOD...HUNTSVILLE TEXAS LINE BY EARLY THIS AFTERNOON.
RELATIVELY CLEAR SKIES IN WAKE OF THIS THUNDERSTORM CLUSTER
ALONG/NORTH OF THIS BOUNDARY WILL CONTRIBUTE TO INCREASINGLY
UNSTABLE CONDITIONS THROUGH THE AFTERNOON. SATELLITE IMAGERY SHOWS
EVIDENCE OF AN UPPER LEVEL IMPULSE OVER NEW MEXICO. AS THIS SYSTEM
APPROACHES...THE THUNDERSTORMS ALREADY FORMING OVER NM WILL
INTENSIFY AS THEY MOVE INTO THE INSTABILITY AXIS OVER TEXAS DURING
THE MID-LATE AFTERNOON.

GIVEN THE RELATIVELY STRONG SHEAR THROUGH THE ATMOSPHERE...THE
INITIAL THUNDERSTORMS WILL LIKELY BECOME SUPERCELLS AND HAVE THE
POTENTIAL TO PRODUCE VERY LARGE HAILSTONES...LARGER THAN 2 INCHES IN
DIAMETER...OVER SOUTHEASTERN NEW MEXICO AND PARTS OF THE PERMIAN
BASIN OF SOUTHWEST TEXAS. TORNADOES WILL ALSO BE POSSIBLE AS THE
STORMS INTERACT WITH THE OUTFLOW BOUNDARY THROUGH EARLY THIS
EVENING.

LATER IN THE EVENING AND OVERNIGHT...THUNDERSTORMS ARE EXPECTED TO
CONGEAL INTO ANOTHER MESOSCALE COMPLEX. INCREASING NORTHWESTERLY
FLOW ALOFT AND MAGNITUDE OF INSTABILITY AHEAD OF THE THUNDERSTORMS
SUGGEST THAT DAMAGING WINDS WILL BECOME MORE OF A THREAT OVERNIGHT
FROM PARTS OF SOUTHWEST THROUGH CENTRAL TEXAS. BY DAYBREAK
MONDAY...EASTERN EXTENT OF THE THUNDERSTORMS MAY REACH THE I-35
CORRIDOR FROM WACO TO NEAR SAN ANTONIO.

THOSE IN THE THREATENED AREA ARE URGED TO REVIEW SEVERE WEATHER
SAFETY RULES AND TO LISTEN TO RADIO...TELEVISION...AND NOAA WEATHER
RADIO FOR POSSIBLE WATCHES...WARNINGS...AND STATEMENTS LATER TODAY.
