CONCERNING...SEVERE THUNDERSTORM WATCH 869...

VALID 230413Z - 230545Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 869
CONTINUES.

A LINE OF STORMS CONTINUES TO SAG SWD ACROSS THE RED RIVER. STORM
CORES HAVE BEEN WEAKENING A BIT OVER ERN AREAS...BUT STORMS OVER S
CNTRL OK REMAIN SEVERE.

THE 00Z FWD SOUNDING SHOWED A LESS FAVORABLE THERMODYNAMIC PROFILE
THAN FARTHER N...WITH A MORE PRONOUNCED WARM LAYER BELOW 700 MB.
HOWEVER...WIND PROFILES HAVE BEEN INCREASING WITH A 30+ KT LOW LEVEL
JET NOTED ON AREAS VADS. THIS MAY HELP TO FUEL A FEW SEVERE STORMS
OVER THE NEXT 2-3 HOURS. HOWEVER...THE THREAT IS NOT EXPECTED TO
REMAIN WIDESPREAD ENOUGH FOR ANOTHER WATCH.

TRENDS WILL BE MONITORED FOR A POSSIBLE PARTIAL LOCAL WATCH
EXTENSION OVER N TX...IF NEEDED.
