AREAS AFFECTED...NORTHERN TEXAS PANHANDLE...CENTRAL OKLAHOMA
PANHANDLE...AND SOUTHWESTERN KANSAS
CONCERNING...TORNADO WATCH 134...
VALID 260042Z - 260245Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 134 CONTINUES.
SUMMARY...SEVERE THREAT CONTINUES ACROSS WW134. ADDITIONAL
THUNDERSTORM DEVELOPMENT POSSIBLE OVER THE NEXT COUPLE OF HOURS.
DISCUSSION...VISIBLE SATELLITE IMAGERY ACROSS THE TEXAS/OKLAHOMA
PANHANDLES CONTINUES TO SHOW AREAS OF TOWERING CUMULUS CLUSTERED
ALONG THE DRYLINE. THUS FAR, ATTEMPTS AT INITIATION HAVE BEEN
UNSUCCESSFUL. THE 00Z RAOB FROM AMA INDICATES MLCIN HAS ERODED AMID
STEEP LAPSE RATES THROUGHOUT THE PROFILE. GIVEN THE INCREASE
EXPECTED IN THE LOW-LEVEL JET THROUGH THE NEXT COUPLE OF HOURS AND
ADDITIONAL SYNOPTIC FORCING FOR ASCENT, FURTHER SCATTERED
THUNDERSTORM DEVELOPMENT WILL BE POSSIBLE. RECENT CAM GUIDANCE
SUPPORTS THIS NOTION, THOUGH THERE ARE DIFFERENCE IN TIMING/LOCATION
OF INITIATION WITHIN THIS REGION. SURFACE OBJECTIVE ANALYSIS
INDICATES AROUND 2500-3000 J/KG MLCAPE WITH DEEP LAYER SHEAR AT
50-55 KTS. GIVEN INITIALLY MODEST FORCING AND SOUTH-SOUTHWESTERLY
DEEP LAYER FLOW, STORMS WILL INITIATE ALONG THE DRYLINE BEFORE
MOVING NORTH EASTWARD WITH THE INITIAL THREAT OF LARGE HAIL AND
DAMAGING WINDS. ANY CELLS THAT MAINTAIN STRENGTH THROUGH THE EVENING
WILL SEE AN INCREASING THREAT FOR TORNADOES AS THE LOW-LEVEL JET
INCREASES ENLARGING HODOGRAPHS AND INCREASING LOW-LEVEL SHEAR.
