345 PM CDT SUN JUL 24 2011
.DISCUSSION...
RADAR SHOWING MORE ACTION THIS AFTERNOON...AS WIDELY SCATTERED SHOWER
AND THUNDERSTORM ACTIVITY IS BEING OBSERVED IN PARTS OF NORTHWEST
LOUISIANA...SOUTHWEST ARKANSAS...AND SOUTHEAST OKLAHOMA. TRIPLE
DIGIT TEMPS ARE ALSO BEING OBSERVED AS ADVERTISED ACROSS MUCH OF
THE WESTERN SECTIONS OF THE CWA.
AN UPPER LEVEL RIDGE WILL CONTINUE TO BUILD OVER THE SOUTHERN
PLAINS THIS PERIOD...THUS KEEPING THE AREA FAIRLY DRY IN THE
WESTERN SECTIONS OF THE CWA AND PROVIDING A DECENT CHANCE OF RAIN
EACH DAY IN THE EAST. AS THE RIDGE HOLDS TO THE WEST...MODELS SHOW A
WEAK UPPER LEVEL TROUGH AXIS WILL LINGER IN THE EAST AND ALLOW
WEAK DISTURBANCES TO PASS NORTH TO SOUTH THROUGH THIS TROUGH
AXIS. THE COMBINATION OF MOISTURE AND DAYTIME HEATING WILL KEEP
WIDELY SCATTERED TO SCATTERED SHOWER AND THUNDERSTORM ACTIVITY IN
THE FORECAST THROUGH THE SHORT TERM.
TRIPLE DIGIT TEMPS WILL CONTINUE IN THE WEST...THUS EXTENDED THE
HEAT ADVISORY THROUGH TOMORROW EVENING...AND THIS MAY GET EXTENDED
FURTHER INTO THE WORK WEEK AS THE CENTURY MARK AND HUMIDITY SHOULD BE
COMMON THROUGHOUT THE WORK WEEK.
TEMPS GUIDANCE CONTINUE TO COME IN ON THE LOW SIDE...ESPECIALLY IN
THE WEST...SO WILL CONTINUE OUR TREND OF WAGERING A COUPLE DEGREES
ABOVE GUIDANCE.

.AVIATION...
SCATTERED CONVECTION EXPECTED TO DISSIPATE BY 25/03Z WITH THE LOSS
OF DAYTIME HEATING. MULTIPLE RESIDUAL OUTFLOW BOUNDARIES LEFT OVER
AS THE STORMS COLLAPSE MAY LEAD TO ERRATIC WINDS FOR THE FIRST FEW
HOURS OF THE 00Z TAF CYCLE. HOWEVER...SOUTH WINDS EXPECTED TO
PREVAIL BY 25/06Z. DRY LOW LEVELS AND ABUNDANT MID LEVEL CLOUDS HAVE
PREVENTED ANY LOW CIGS THE LAST SEVERAL DAYS AND THIS TREND IS
EXPECTED TO CONTINUE. THUS...VFR CONDITIONS SHOULD PREVAIL THROUGH
THE TAF PERIOD BUT MVFR CONDITIONS AND GUSTY WINDS WILL BE POSSIBLE
WITH ANY TSTMS. /09/
