AREAS AFFECTED...WRN AND CENTRAL OK/WRN N TX

CONCERNING...TORNADO WATCH 137...

VALID 070353Z - 070600Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 137 CONTINUES.

SUMMARY...SEVERE/ISOLATED TORNADO THREAT CONTINUES -- PARTICULARLY
ACROSS SRN PORTIONS OF THE WATCH ACROSS WRN N TX.

DISCUSSION...LATEST RADAR LOOP SHOWS SCATTERED STRONG/ISOLATED
SEVERE STORMS ONGOING ACROSS THE WW AREA...WITHIN AN
MOIST/UNSTABLE/FAVORABLY SHEARED ENVIRONMENT.  THE MOST SIGNIFICANT
STORMS ATTM ARE ONGOING ACROSS WRN N TX...WHERE SEVERAL LARGE
SUPERCELL STORMS ARE ONGOING.  THE GREATEST SHORT-TERM TORNADO RISK
WILL PERSIST IN THIS AREA...ALONG WITH POTENTIAL FOR LOCALLY
DAMAGING WINDS AND VERY LARGE HAIL.

MEANWHILE FARTHER N...ISOLATED SEVERE STORMS ARE ONGOING ACROSS
PARTS OF WRN...CENTRAL...AND NRN OK...WHERE LARGE HAIL AND LOCALLY
DAMAGING WINDS REMAIN POSSIBLE.

EXPECT A GRADUAL DECREASE IN SEVERE RISK AFTER MIDNIGHT...AS MODELS
SHOW WEAKENING IN THE FLOW FIELD ALOFT WITH TIME AS THE UPPER TROUGH
CONTINUES SHIFTING NNEWD AWAY FROM THE SRN PLAINS.  HOWEVER...SEVERE
RISK COULD SLOWLY TRANSITION TOWARD THAT OF PRIMARILY HEAVY
RAINS/FLOODING ACROSS WRN N TX...AS A PERSISTENT SLY LOW-LEVEL JET
REMAINS FOCUSED ACROSS THIS AREA OVERNIGHT ALLOWING STORMS TO
PERSIST.
