AREAS AFFECTED...NORTHWEST OK AND THE EASTERN TX PANHANDLE
CONCERNING...SEVERE THUNDERSTORM WATCH 345...
VALID 290214Z - 290345Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 345
CONTINUES.
SUMMARY...PRIMARY SEVERE THREAT AREA THROUGH LATE EVENING IS
EXPECTED TO EVOLVE FROM PARTS OF THE EASTERN TEXAS PANHANDLE INTO A
GREATER PORTION OF NORTHWEST OKLAHOMA. A MIX OF SEVERE WIND AND HAIL
IS ANTICIPATED.
DISCUSSION...LEADING STORM CLUSTERS CONSISTING OF A COUPLE
SUPERCELLS ALONG THE NORTH-NORTHEAST END AND OUTFLOW-DOMINATED
CONVECTION TO ITS SOUTHWEST WILL LIKELY PERSIST EAST-SOUTHEAST
THROUGH LATE EVENING. THIS ACTIVITY SHOULD BE SUSTAINED BY A
MODERATE LOW-LEVEL JET, AS SAMPLED BY VNX AND AMA VWP DATA, WITH A
RESIDUAL PLUME OF MODEST BUOYANCY EMANATING NORTH FROM WESTERN NORTH
TX. A MIX OF SPORADIC SEVERE WIND AND HAIL SHOULD REMAIN THE PRIMARY
HAZARDS AMID MODEST STORM MOTION OF 25-30 KTS. THIS ACTIVITY STILL
SEEMS LIKELY TO REMAIN LARGELY SEPARATE FROM AN UPSTREAM CORRIDOR OF
ELEVATED STORMS ACROSS SOUTHERN KS, BUT MAY EVENTUALLY MERGE ALONG
THE NORTHEAST PORTION. GIVEN NOCTURNAL WEAKENING OF INSTABILITY AND
INCREASING MLCIN ACROSS THE TX PANHANDLE, THE OVERALL SEVERE THREAT
SHOULD BECOME MORE CONFINED INTO OK WITH A GRADUAL WEAKENING OF
INTENSITY TONIGHT.
