CONCERNING...TORNADO WATCH 288...
VALID 190120Z - 190215Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 288 CONTINUES.
SUMMARY...THE SUPERCELL TORNADO THREAT CONTINUES, THOUGH IT IS
UNCLEAR HOW FAR EAST THE RISK WILL SPREAD.
DISCUSSION...A WELL-ESTABLISHED SUPERCELL WITH A HISTORY OF
PRODUCING TORNADOES AND VERY LARGE HAIL CONTINUES ACROSS PARTS OF
NORTH-CENTRAL TX. THIS STORM IS STILL IN A VERY FAVORABLE
ENVIRONMENT -- CHARACTERIZED BY 270-300 M2/S2 0-1KM SRH (PER NEARBY
VWP DATA) AND STRONG SURFACE-BASED INSTABILITY. GIVEN THIS
ENVIRONMENT AND THE ONGOING STRONG MESOCYCLONE, THE TORNADO,
LARGE-HAIL, AND DAMAGING-WIND THREAT CONTINUES. IT IS UNCLEAR HOW
LONG THIS SUPERCELL WILL MAINTAIN ITS CURRENT INTENSITY WITH
EASTWARD EXTENT, AS IT GRADUALLY ENCOUNTERS INCREASING INHIBITION
(SAMPLED BY FWD 00Z SOUNDING). HOWEVER, THE AFOREMENTIONED STRONG
MESOCYCLONE AND LARGE STORM-SIZE MAY ALLOW IT TO PERSIST -- WITH AN
ACCOMPANYING ALL-HAZARDS RISK.
