SPC MESOSCALE DISCUSSION 0332 FOR NORTHERN AND WESTERN TEXAS AND
THE EXTREME SOUTHERN PANHANDLE
CONCERNING...SEVERE THUNDERSTORM POTENTIAL...

VALID 232319Z - 240300Z

WE ARE MONITORING THIS AREA FOR ADDITIONAL CONVECTIVE DEVELOPMENT
THROUGH THE LATE AFTERNOON/EARLY EVENING HOURS.  A WEATHER WATCH
COULD BE REQUIRED IN THE NEXT SEVERAL HOURS OVER PORTIONS OF WEST
CENTRAL AND NORTH CENTRAL TEXAS.

LATEST MESOANALYSIS SHOWS A MULTITUDE OF BOUNDARIES ACROSS PORTIONS
OF EASTERN NEW MEXICO INTO NORTHERN AND WESTERN TEXAS.  THE LATEST
VISIBLE IMAGERY SHOWED A LINE OF CUMULUS/TOWERING CUMULUS ALONG A
LINE FROM NEAR ABILENE TO NEAR LUBBOCK.  SURFACE OBSERVATIONS SHOW
LOW LEVEL MOISTURE IS RATHER LIMITED OVER WESTERN TEXAS...BUT HAS
BEEN GRADUALLY INCREASING ACROSS THE SOUTH PLAINS AND NORTHWEST
PARTS OF THE STATE.  AS A RESULT...INSTABILITY ACROSS THE AREA HAS
BEEN INCREASING DURING THE PAST SEVERAL HOURS.

WATER VAPOR IMAGERY SHOWS A SPEED MAX MOVING ACROSS THE NORTHERN
PANHANDLE WHICH HAS AIDED THUNDERSTORM DEVELOPMENT ACROSS THAT AREA
DURING THE PAST SEVERAL HOURS.  THE LATEST ETA GUIDANCE SUGGESTS
THIS FEATURE WILL MOVE SOUTHEASTWARD INTO NORTHERN TEXAS LATER THIS
EVENING.  AS THIS HAPPENS...THE COMBINATION OF THE UPPER FORCING
AND LOW LEVEL FORCING ASSOCIATED WITH THE SURFACE BOUNDARIES SHOULD
ALLOW ADDITIONAL STORMS TO DEVELOP THROUGH THE EVENING.  THE
INCREASING LOW LEVEL MOISTURE VALUES OVER NORTHWEST TEXAS SUGGESTS
THE BASES ON THE STORMS WILL LOWER...LIKELY BECOMING SURFACE BASED. 
FORECAST AND CURRENT WIND PROFILES SHOW STRONGLY VEERING FLOW...
ALTHOUGH SPEEDS ARE SOMEWHAT WEAK.  THIS WOULD LIKELY SUPPORT
SCATTERED SUPERCELLS THROUGH THE EVENING...BUT THE WEAK WINDS
INDICATE THE PRIMARY THREAT WOULD BE FROM LARGE HAIL AND STRONG
WINDS.
