AREAS AFFECTED...WRN TX...OK PANHANDLE AND SWRN KS
CONCERNING...TORNADO WATCH 190...
VALID 230002Z - 230200Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 190 CONTINUES.
SUMMARY...THREAT FOR VERY LARGE HAIL...TORNADOES AND DAMAGING WIND
GUSTS WILL PERSIST THROUGH 03Z FROM PORTIONS OF WRN TX INTO THE TX
AND OK PANHANDLES AND SWRN KS.
DISCUSSION...NUMEROUS STORMS INCLUDING SUPERCELLS THAT INITIATED
ALONG AND JUST AHEAD OF DRYLINE PERSIST FROM NWRN TX NWD INTO SWRN
KS. VERY LARGE HAIL AND TORNADOES HAVE BEEN REPORTED WITH THESE
STORMS...AND THIS THREAT WILL LIKELY PERSIST DURING THE NEXT 2-3
HOURS BEFORE A GRADUAL WEAKENING TREND BEGINS. VWP DATA FROM
AMARILLO HAVE SHOWN A NOTABLE INCREASE IN BOTH 0-1 KM HODOGRAPHS
SIZE /200-250 0-1 KM STORM RELATIVE HELICITY/ AND MID-LEVEL WINDS.
THESE STORMS REMAIN IN A FAVORABLE LOCATION TO INGEST AIR FROM A
VERY MOIST AND UNSTABLE BOUNDARY LAYER WHERE WARM-SECTOR CAPE RANGES
FROM 2500-3500 J/KG. STORMS REMAIN RELATIVELY DISCRETE DESPITE
NUMEROUS STORM MERGERS...AND THE THREAT FOR VERY LARGE HAIL AND
TORNADOES WILL PERSIST NEXT 2-3 HOURS.
ONSET OF NOCTURNAL COOLING WILL RESULT IN A GRADUAL INCREASE IN
CONVECTIVE INHIBITION...AND STORMS SHOULD BEGIN A WEAKENING TREND BY
03Z. HOWEVER...THE STRENGTHENING LLJ MIGHT FOSTER THE MAINTENANCE OF
ONE OR MORE STORM CLUSTERS INTO THE LATE EVENING...BUT IF THIS
OCCURS PRIMARY THREAT WILL TRANSITION TO DAMAGING WIND.
