AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
941 AM CDT SAT AUG 18 2007
.DISCUSSION...
SKIES ARE MOSTLY SUNNY ACROSS THE FORECAST AREA THIS MORNING WITH
TEMPERATURES IN THE 80S. A FEW THUNDERSTORMS HAVE POPPED UP ACROSS
CENTRAL ARKANSAS THIS MORNING AND ARE GENERALLY MOVING NORTH.
COULD SEE SOME AFTERNOON THUNDERSTORM DEVELOPMENT ACROSS THE
FORECAST AREA LATER TODAY. ANOTHER HOT DAY IS EXPECTED WITH
TEMPERATURES EXPECTED TO REACH TRIPLE DIGITS. WILL UPDATE FORECAST
TO REMOVE SOME MORNING WORDING BUT NO MAJOR CHANGES ARE PLANNED AT
THIS TIME.
&&
.PREV DISCUSSION... /ISSUED 316 AM CDT SAT AUG 18 2007/
DISCUSSION...
TEMPERATURES THIS MORNING WERE RUNNING A TAD COOLER THAN YESTERDAY
WHERE CLOUDS WERE NOT PRESENT. MORNING TEMPERATURES RANGED FROM
THE MID 70S TO LOWER 80S ACROSS THE MID SOUTH. A FRONTAL BOUNDARY
WAS LOCATED ROUGHLY FROM CHATTANOOGA TO UNION CITY TO SALEM
MISSOURI. DEW POINTS BEHIND THE FRONT WERE IN THE UPPER 50S TO
LOWER 60S.
THE HEAT IS GOING TO PERSIST ACROSS THE MID SOUTH THROUGH THE
WEEKEND AND INTO NEXT WEEK. THE HEAT ADVISORY HAS BEEN EXPANDED TO
THE NORTHEAST TODAY ROUGHLY ALONG AND WEST OF A HAYTI TO JACKSON
TO DECATURVILLE LINE. AN ADDITIONAL HEAT ADVISORY WILL BE NECESSARY
FOR THE WHOLE AREA SUNDAY...BUT TO AVOID CONFUSION IN THE
PRODUCT...WILL ALLOW THE FOLLOWING SHIFT TO EXTEND THE HEAT ADVISORY
INTO SUNDAY.
THE FRONT AND ASSOCIATED LOWER DEW POINTS ARE GOING TO SLOWLY SEEP
SOUTHWEST TODAY AFFECTING THE HEAT INDEX. HOWEVER...TEMPERATURES
WILL STILL BE CLOSE TO 100 DEGREES WHERE THE HEAT ADVISORY IS NOT
IN EFFECT.
LIKE YESTERDAY...A FEW ISOLATED THUNDERSTORMS COULD BECOME SEVERE
IN THE AFTERNOON PRODUCING LARGE HAIL AND DAMAGING WINDS. EXPECT
STORMS TO DEVELOP IN AREAS WHERE THE DEW POINTS REMAIN AROUND 70
DEGREES. CONVECTIVE TEMPERATURES ARE AROUND 100 DEGREES.
ANTICIPATE AREAS ACROSS NORTHEAST ARKANSAS...SOUTHWEST TN AND
NORTHWEST MS TO BE AFFECTED MOST.
CLOUD COVER DID NOT INHIBIT MAX TEMPERATURES ON FRIDAY AND WOULD
EXPECT MUCH THE SAME TODAY AND SUNDAY. HOWEVER...THICKER CLOUD
COVER WHERE STORMS DEVELOP WILL LIKELY COOL TEMPERATURES LATE IN
THE AFTERNOON.
THE UPPER RIDGE HOLDS STRONG AND WILL BE AT ITS STRONGEST OVER THE
REGION BY WEDNESDAY. AT THIS TIME...IT APPEARS AS THOUGH THE RIDGE
WILL WEAKEN BY THE END OF NEXT WEEK AND PERHAPS SOME RELIEF IS
POSSIBLE BY NEXT WEEKEND.
