NWS STORM PREDICTION CENTER NORMAN OK
1046 AM CDT MON MAR 19 2012
AREAS AFFECTED...WEST-CENTRAL TX
CONCERNING...SEVERE THUNDERSTORM WATCH 84...
VALID 191546Z - 191715Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 84
CONTINUES.
ISOLATED SEVERE HAIL REMAINS POSSIBLE ACROSS PORTIONS OF
WEST-CENTRAL TX...BUT THE OVERALL SEVERE THREAT SHOULD REMAIN
LIMITED. THEREFORE...SEVERE TSTM WATCH 84 WILL LIKELY BE ALLOWED TO
EXPIRE AT/BY 17Z.
TSTM CLUSTERS WILL LIKELY REMAIN FOCUSED ALONG/JUST BEHIND A SLOW
EASTWARD-MOVING CONVECTIVE BOUNDARY ACROSS WEST-CENTRAL TX INTO THE
AFTERNOON. GIVEN THE LACK OF AN EXTENSIVE COLD POOL AND NEBULOUS
LARGE SCALE FORCING AT THIS TIME...AHEAD OF A MORE SUBSTANTIAL
SHORTWAVE TROUGH AND JET STREAK ACROSS THE SOUTHERN FOUR
CORNERS/NORTH MEXICO...A SIMILAR NEAR/POST-OUTFLOW FOCUSED
CONVECTIVE MODE SHOULD PERSIST. THIS WILL TEND TO LIMIT DAMAGING
WIND POTENTIAL...AND WHILE VERY STEEP LAPSE RATES EXIST ACROSS THE
REGION...THE EXISTING/EXPECTED CONVECTIVE MODE AND ASSOCIATED
INDIVIDUAL UPDRAFT INTERFERENCE WILL TEND TO ALSO LIMIT THE SEVERE
HAIL LIKELIHOOD.
