MESOSCALE DISCUSSION 1343
NWS STORM PREDICTION CENTER NORMAN OK
0911 PM CDT FRI JUN 18 2004

AREAS AFFECTED...FAR NERN NM/WEST CENTRAL TX AND TX/OK PANHANDLES

CONCERNING...SEVERE THUNDERSTORM WATCH 496...497...

VALID 190211Z - 190245Z

WW 497 WILL BE REPLACED WITH NEW WW FOR THE SAME AREA.

OUTFLOW BOUNDARY FROM EARLIER CONVECTION ACROSS OK/NRN TX HAS
CONTINUED TO MOVE W AND SW ACROSS THE TX PANHANDLE AND WEST CENTRAL
TX.  CLUSTERS OF STORMS WILL CONTINUE TO DEVELOP AS THIS OUTFLOW
BOUNDARY INTERSECTS THE COLD FRONT ACROSS THE NRN TX PANHANDLE...AND
AS STORMS OVER NERN NM MOVE EWD INTO TX MERGING WITH THE STORMS
ALONG THE COLD FRONT.  A CLUSTER OF STORMS FARTHER SOUTH FROM YOAKUM
COUNTY TX TO CASTRO COUNTY TX HAS DEVELOPED A COLD POOL WITH FORWARD
PROPAGATION LIKELY...AT LEAST FOR THE NEXT SEVERAL HOURS.  THIS
CLUSTER WILL INTERACT WITH THE WWD MOVING LARGE OUTFLOW BOUNDARY...
AND SHOULD RESULT IN FURTHER STORM INTENSIFICATION.

AIR MASS ACROSS THESE AREAS REMAINS MODERATELY UNSTABLE...WITH
STRONG DEEP LAYER SHEAR CONTINUING TO SUPPORT SUPERCELLS WITH LARGE
HAIL AND DAMAGING WINDS THE PRIMARY THREATS.

ALTHOUGH MUCH OF THE OK PANHANDLE IS NORTH OF THE COLD FRONT/IN A
MORE SLIGHTLY STABLE AIR MASS...STORMS ACROSS NERN NM/SERN CO MAY
MOVE SEWD ACROSS THIS REGION POSING A THREAT FOR ELEVATED SEVERE
STORMS.
