AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 1049 AM CDT SAT AUG 31 2013 .DISCUSSION... AT 1530Z...SHORTWAVE TROUGH WAS ROUGHLY CENTERED OF KTXK AND SHOULD CONTINUE TO SLOWLY MOVE SOUTH GENERALLY ALONG THE LA/TX STATE LINE. 12Z KSHV SOUNDING INDICATED A FAIRLY SUBSTANTIAL CAP NEAR 800 MB. IT WILL LIKELY TAKE SFC TEMPS OVER 100 DEGREES F TO FULLY ERODE THE CAP. THUS...ANY CONVECTIVE COVERAGE WILL LIKELY BE QUITE LIMITED. HOWEVER...THE SHORTWAVE WILL BE OVER THE CENTER OF THE CWA AT PEAK HEATING SO CONVECTIVE DEVELOPMENT WILL BE POSSIBLE JUST ABOUT ANYWHERE. THEREFORE...EXPANDED SLIGHT CHANCE POPS AREAWIDE FOR THIS AFTERNOON. ANY SHWRS/TSTMS THAT DO DEVELOP SHOULD GRADUALLY DIMINISH FROM NORTH TO SOUTH THIS EVENING DUE TO SUBSIDENCE IN THE WAKE OF THE TROUGH AND THE LOSS OF DAYTIME HEATING. OTHERWISE...MADE SOME UPDATES TO THE SKY GRIDS BASED ON LATEST TRENDS. UPDATED PRODUCTS HAVE ALREADY BEEN SENT. /09/ && .AVIATION... UPPER LEVEL DISTURBANCE OVERHEAD LATE THIS MORNING WILL CONTRIBUTE TO DEVELOPMENT OF SCATTERED CLOUDS AROUND 6 KFT AND 9 KFT THIS AFTERNOON AS THE FEATURE DRIFTS SOUTH. STRONG HEATING AND AVAILABLE MOISTURE BENEATH THIS SYSTEM MAY RESULT IN ISOLATED ELEVATED CONVECTION DEVELOPING AFTER 31/21 UTC FOR JUST ABOUT ANYWHERE OVER THE FOUR STATE REGION...WITH SOME LINGERING INTO THE EVENING. WILL NOT MENTION IN THE TERMINALS SINCE CHANCE FOR CONVECTION SMALL AND SKILL OF PICKING ONE OF THE TERMINAL FORECAST SITES TO INCLUDE VERY SLIM. SURFACE WINDS SOUTH TO SOUTHWEST 5 TO 10 KNOTS THROUGH 01/00 UTC THEN A SLIGHT DECREASE THROUGH 01/15 UTC WHEN SPEEDS EXPECTED TO INCREASE BACK TO 5 TO 10 KNOTS. /06/ && .PREV DISCUSSION... /ISSUED 318 AM CDT SAT AUG 31 2013/ DISCUSSION...

DESPITE VERY DRY AIRMASS ACROSS REGION...UNSEASONALLY STG SHORT WAVE DIVING SWD ALONG EASTERN EDGE OF RIDGE...INTO REGION THIS AFTN. INCREASED LOW LVL S-SW WINDS...AS SEEN BY OVERNIGHT SFC WINDS FROM SOUTH AT LEAST 5 TO 10 MPH AREAWIDE...IN RESPONSE TO THIS APPROACHING SHORT WAVE. THIS FLOW COULD NUDGE TEMPS UP SLIGHTLY TO OVER THE 100 DEGREE MARK...HOWEVER...INCREASED CUMULUS DEVELOPMENT DUE TO THE LIFT ASSOCIATED WITH THIS SMALL UPPER LOW...WILL LIKELY COUNTERACT ADDITIONAL WARMING...WITH AFTN HIGHS IN UPPER 90S TO AROUND 100 EXPECTED ONCE AGAIN TODAY. THIS LIFT ACTING ON VERY MARGINAL MOISTURE WILL RESULT IN A QUESTIONABLE ISOLD TSTM DEVELOPMENT THIS AFTN...WILL LEAVE IN 20 PERCENT POPS...MAINLY ALONG AND NORTH OF I-20. AFTN DEWPOINTS EXPECTED TO ONCE AGAIN MIX OUT SLIGHTLY TO THE LOWER TO MID 60S...THUS AVOIDING HEAT INDICES FROM EXCEEDING ACTUAL TEMPS FOR THE MOST PART TODAY. SUBSIDENCE IN THE WAKE OF THIS SWD MOVG LOW SHOULD MINIMIZE ANY CHANCES OF CONVECTION ON SUNDAY. HOWEVER...A WEAK FRONTAL BOUNDARY ARRIVING LATER ON MONDAY WILL RESULT IN ISOLD...TO POSSIBLY SCATTERED...DEVELOPMENT TO OCCUR NEAR THIS FRONTAL BOUNDARY. AFTN HIGHS TO RISE TO MID/UPPER 90S FOR THE MOST PART FOR MUCH OF THE WEEK...AND WILL COMBINE WITH SLIGHTLY LESS HUMIDITY LATER IN THE WEEK AS HIGH PRESSURE FROM THE NORTH BUILDS INTO THE REGION./VII/. && .PRELIMINARY POINT TEMPS/POPS...
