AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MEMPHIS TN 1241 PM CDT SAT JUN 26 2010 .DISCUSSION... UPDATED FOR 18Z AVIATION DISCUSSION && .PREV DISCUSSION... /ISSUED 1103 AM CDT SAT JUN 26 2010/ UPDATE... ANOTHER TYPICAL SUMMER DAY IS OCCURRING ACROSS THE MIDSOUTH. CURRENT TEMPERATURES HAVE WARMED INTO THE MID TO UPPER 80S ACROSS MUCH OF THE CWA. TEMPERATURES ARE A TAD COOLER ACROSS NORTHEAST MISSISSIPPI DUE TO LEFTOVER CLOUD COVER FROM THIS MORNINGS CONVECTION. HOWEVER TEMPERATURES SHOULD REBOUND QUICKLY AS CLOUDS CONTINUE TO PUSH OFF TO THE EAST. HIGHS SHOULD GET INTO THE LOWER TO MID 90S. WILL ALSO ADJUST POPS TO 30 EVERYWHERE SINCE HIGHER POPS ACROSS NORTHEAST MISSISSIPPI ARE NO LONGER JUSTIFIED AS THIS MORNINGS CONVECTION HAS SHIFTED EAST. DIURNAL THUNDERSTORM DEVELOPMENT IS EXPECTED THIS AFTERNOON. UPDATE WILL BE OUT SHORTLY. KRM PREV DISCUSSION... /ISSUED 429 AM CDT SAT JUN 26 2010/ CONDITIONS WERE RAIN-FREE EARLY THIS MORNING WITH PARTLY CLOUDY SKIES. TEMPERATURES RANGED FROM THE 60S ACROSS THE TN RIVER VALLEY TO THE 70S ELSEWHERE. A LARGE AREA OF HIGH PRESSURE STRETCHED FROM THE OFF THE ATLANTIC COAST WESTWARD ACROSS THE MIDSOUTH. SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP AGAIN TODAY...ESPECIALLY THIS AFTERNOON. MOIST TROPICAL-LIKE AIR COVERED THE MIDSOUTH WITH PRECIPITABLE WATER VALUES CLOSE TO 2 INCHES...150 PERCENT ABOVE NORMAL FOR THIS TIME OF THE YEAR. WITH STRONG HEATING...SBCAPES ARE FORECAST TO CLIMB TO BETWEEN 2000 AND 4000 J/KG WITH LIFTED INDICES NEAR MINUS 6 DEGREES. A FEW STRONG TO SEVERE THUNDERSTORMS ARE AGAIN POSSIBLE WITH DAMAGING WINDS. HIGH WBZ HEIGHTS OF 14 KFT SHOULD LIMIT ANY LARGE HAIL. HEAVY RAINFALL IS ALSO POSSIBLE AGAIN WITH SLOW MOVING THUNDERSTORMS AND LOCALIZED FLASH FLOODING MAY OCCUR. HEAT INDEX READINGS WILL CLIMB TO BETWEEN 100 AND 104 DEGREES...JUST SHY OF HEAT ADVISORY CRITERIA...BEFORE ANY COOLING OCCURS FROM THUNDERSTORMS. THIS WILL HAVE TO BE MONITORED FOR THE POSSIBILITY OF HEAT ADVISORIES MAINLY ALONG AND WEST OF THE MS RIVER AND ESPECIALLY IF CONVECTION DOES NOT DEVELOP AS EXPECTED. LITTLE CHANGE IS EXPECTED FOR SUNDAY. MODELS HAVE BEEN INDICATING A LITTLE DRIER AIR ALOFT MOVING INTO THE REGION FROM THE WEST. THUS MAY SEE A LITTLE LESS CONVECTION WITH SLIGHTLY HOTTER TEMPERATURES THAN TODAY. HEAT INDEX READINGS ARE ONCE AGAIN EXPECTED TO REACH BETWEEN 100 AND 104 DEGREES...WITH SURFACE DEW POINTS PERHAPS MIXING DOWN SLIGHTLY IN THE AFTERNOON. ONCE AGAIN SOME LOCATIONS WILL BE CLOSE TO HEAT ADVISORY CRITERIA. MODELS ARE IN BETTER AGREEMENT WITH THE FORECAST WEATHER PATTERN CHANGE FOR NEXT WEEK WITH THE GFS COMING IN BETTER AGREEMENT WITH WHAT THE ECMWF HAS BEEN INDICATING. EARLIER FORECAST THAT HAS BEEN BASED MORE ON THE ECMWF STILL LOOKS GOOD. UPPER LEVEL HEIGHTS ARE FORECAST TO WEAKEN ACROSS THE MIDSOUTH MONDAY AS AN UPPER LEVEL TROUGH SWINGS THROUGH THE NORTHEASTERN UNITED STATES AND HIGH PRESSURE ALOFT BUILDS OVER THE ROCKIES. THIS WILL ALLOW A COLD FRONT TO MOVE THROUGH THE REGION FROM THE NORTH MONDAY NIGHT AND TUESDAY. CONTINUED WITH A CHANCE OF THUNDERSTORMS MONDAY INTO TUESDAY. LESS HUMID AIR IS FORECAST TO SPREAD INTO THE MIDSOUTH BEHIND THE FRONT AND PERSIST THROUGH THE END OF THE WORK WEEK. UPPER LEVEL RIDGING WILL GRADUALLY SHIFT TO THE EAST OVER THE MIDSOUTH. THE LESS HUMID AIR WILL ALLOW FOR COOLER NIGHTS BUT DAYS WILL STILL BE VERY WARM. JCL .AVIATION... 18Z TAF CYCLE SCT TSRA WILL CONTINUE TO DEVELOP ACROSS THE MID SOUTH DISSIPATING BY ABOUT 27/03Z. ATTM HARD TO PINPOINT BEST TIME FOR TSRAS AT ANY GIVEN TAF SITE SO WILL CONTINUE VCTS WORDING FOR NOW. MAINLY VFR CONDS ARE EXPECTED OTHERWISE. COULD BE SOME LIGHT FOG AROUND LATER TONIGHT BUT NOT CONFIDENT TO PLACE IN TAFS ATTM.
