256 PM CDT FRI JUL 25 2014

.SHORT TERM (TONIGHT THROUGH SATURDAY NIGHT)...ONGOING CONVECTION
SHOULD DISSIPATE LATE THIS AFTERNOON/EARLY EVENING WITH LOSS OF
DAYTIME HEATING. CLOUD COVER WILL ALSO DISSIPATE THIS EVENING WITH
MAINLY CLEAR SKIES EXPECTED OVERNIGHT. BY LATE TONIGHT AN
UNSEASONABLY MODERATE TO STRONG SRLY LLJ IS PROG TO DEVELOP OVER
WESTERN HALF OF CWA. THIS MAY AID IN A BRIEF PERIOD OF LLVL CLOUD
DEVELOPMENT AROUND SUNRISE. A DECREASE IN DEEP LAYER MOISTURE ON
SATURDAY AND AN INCREASE IN H9 TO H7 LAYER TEMPS SHOULD RESULT IN
A DRIER DAY ACROSS THE REGION WITH LITTLE TO NO DIURNAL
CONVECTION. COMBINATION OF HOT MAX TEMPS AND HIGH SURFACE
DEWPOINTS MAY ALLOW SOME LOCATIONS TO APPROACH HEAT ADVISORY
CRITERIA...WITH MOST AREAS HAVING AFTERNOON/EARLY EVENING HEAT
INDICES OF 105 TO 109 DEGREES. WIND SPEEDS SATURDAY
AFTERNOON/EARLY EVENING WILL LIKELY BE THE BREEZIEST OF THIS WEEK
AS STRONG THERMAL GRADIENT SETS UP FROM EAST TO WEST ACROSS THE
CWA. LLJ REDEVELOPMENT FRIDAY SATURDAY NIGHT SHOULD AID IN KEEPING
MIN TEMPS A LITTLE ABOVE SEASONABLE LEVELS FOR A SECOND NIGHT.

&&

.LONG TERM (SUNDAY THROUGH FRIDAY)...A BROAD SUBTROPICAL RDG AXIS
CENTERED ACROSS THE FOUR CORNERS RGN WL MAINTAIN A DRY SUBSIDENT
AIRMASS THROUGH AT LEAST TUESDAY ACROSS THE CWA. A BACKDOOR COLD
FRONT APPROACHING FROM THE NORTHEAST IS EXPECTED TO WEAKEN ACROSS
SOUTHEAST TEXAS AS IT ENCOUNTERS THE SUBSIDENT AIRMASS. THUS MOST IF
NOT ALL OF THE PCPN ASSCTD WITH THIS FEATURE SHOULD REMAIN NORTH AND
NORTHEAST OF THE CWA ON TUESDAY AND WEDNESDAY.  HOWEVER BY THURSDAY
AND FRIDAY A MORE POTENT FRONT AND S/WV WL BE AFFECTING THE CWA.
THIS WL BE IN RESPONSE TO THE FULL LATITUDE TROUGH AXIS ACROSS THE
EASTERN UNITED STATES DEEPENING AS IT DROPS FURTHER SWD.  INCREASING
DEEP LAYER FORCING AND PWATS ABV 2 INCHES IN CONJUNCTION WITH THIS
SLOW-MOVING FRONT WL BE SUFFICIENT TO PRODUCE CONVECTION FOR
THURSDAY BUT MORE SO ON FRIDAY.  DRY SUBSIDENT CONDITIONS THROUGH
MIDWEEK WL MAINTAIN SLIGHTLY ABV NORMAL TEMPS.  OVERALL THE SFC
DEWPOINTS SHOULD TEND TO MIX OUT AND KEEP HEAT INDICES BELOW HEAT
ADVY CRITERIA.  WENT ACTUALLY SLIGHTLY BELOW NORMAL FOR TEMPS BY
FRIDAY GIVEN THE INCREASED CLOUD CVR AND RAIN CHANCES.
