AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 500 AM CDT FRI JUL 13 2012 .DISCUSSION... MORE LOW CLOUDS THAN FOG THIS MORNING WITH MOSTLY LOW 70S. A FEW DEW POINTS ARE IN THE UPPER 60S AND MAY YIELD A FEW SUCH MORNING LOWS. THERE ARE SOME RAIN CLOUDS WITH THUNDER IN FACT...DOWN IN DEEP EAST TEXAS AND TOLEDO BEND COUNTRY TO RIGHT ALONG I-49 IN LOUISIANA. MOVEMENT OF THIS ACTIVITY IS TO THE NORTHEAST AT 10 TO 15 MPH. THE WATER VAPOR IMAGERY SHOWS THE AXIS OF DEEP MOISTURE RIGHT THROUGH THE UPPER LOW NOW OVER THE HEART OF THE CWA. ALL OF THE THUNDERSTORMS THIS MORNING ARE TO THE EAST OF THAT AXIS FROM DOWN NEAR BEAUMONT ON UP TO NEAR PINE BLUFF. AFTERNOON HEATING WILL LIKELY EXTEND THE POTENTIAL FOR THUNDER BACK WESTWARD ACROSS ALL OF OUR CWA AND WHILE COVERAGE WILL REMAIN HIGHEST OVER THE SOUTHEAST CORNER...ANYWHERE COULD SEE MORE BENEFICIAL MID SUMMER RAINFALL. WE DID SEE A FEW HAIL PRODUCERS NEAR BY LATE YESTERDAY AT MENA AND THEY MOVED INTO THE CWA DURING THE MID EVENING...BUT WEAKEN WITH THE LOSS OF HEATING AFTER SUNSET. MID AFTERNOON LAPS CAPE VALUES FOR I-30 IS IN THE 2500J/KG RANGE...SO AS FAR AS HAZARDOUS WEATHER GOES LITTLE HAS CHANGED WITH SMALL HAIL OR SOME WIND POSSIBLE OVER THE NW CORNER WHERE SURFACE TEMPS WILL BE WARMEST AND ALOFT REMAINS COOLEST. MEANWHILE...WE WILL SEE THE THREAT FOR HEAVY RAIN PRODUCERS ANYWHERE EAST OF THAT AXIS WHERE THE DEEP TROPICAL MOISTURE CONTINUES TO RESIDE. IN ADDITION...THE WATER VAPOR IMAGERY DOES SHOW SOMEWHAT OF AN EASTWARD PUSH OF DRIER MID AND UPPER AIR OVER TOLEDO BEND COUNTRY DURING THE LAST FEW HOURS...BUT OVERALL WE HAVE KEPT THE SAME POPS IN PLACE ACROSS THE CWA FOR THE DAYLIGHT HOURS. ELSEWHERE...AN UPPER LOW OVER THE CENTRAL GULF WILL KEEP MOISTURE DEEP OVER OUR EAST AND THE UPPER RIDGE OVER THE WEST HAS MORE ENERGY DIVING SSW ACROSS OK AND N TX INTO THE LIKELY FURTHER DEEPENING TROUGH FARTHER INTO MEXICO. PECULIAR FOR SUMMER WITH THE BASE OF THIS TROUGH ALREADY PUSHING INTO N MEXICO AND APPARENTLY HEADED FOR THE EQUATOR AFTER MISSING THE TURN YESTERDAY. AT ANY RATE LOW LEVEL MOISTURE REMAINS THICK EVEN AS FAR WEST AS DALLAS AND OKLAHOMA CITY. WE WILL KEEP WITH DECENT RAIN CHANCES FOR A FEW DAYS OR MORE WITH MAINLY DIURNAL ACTIVITY EXPECTED OVER THE WEEKEND AND INTO EARLY NEXT WEEK. LITTLE CHANGE IN THE EXTENDED PORTION WITH SOME WHAT OF A WARMING TREND TO CONTINUE BEYOND MID MONTH. /24/ && .AVIATION... WIDESPREAD IFR CEILINGS AND SCT IFR VSBYS TO DOMINATE DURING THIS FRIDAY MORNING DUE TO OUR MOIST GROUND FROM RECENT HEAVY RAINFALL AND DEEP TROPICAL MOISTURE. EXPECT IMPROVING CONDITIONS BY 15Z THIS FRIDAY...BUT THEN SCT TSTMS TO DEVELOP AGAIN WITH DAYTIME HEATING TO PRODUCE SCT MVFR CEILINGS AND VSBY AT TIMES ESPECIALLY DURING THIS AFTERNOON. BY LATE THIS FRIDAY EVENING AFTER SUNSET...TSTMS SHOULD SLOWLY DISSIPATE AND CONDITIONS SHOULD RETURN TO VFR THROUGH 05Z. /VIII./ && .PRELIMINARY POINT TEMPS/POPS...
