AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MEMPHIS TN
917 PM CDT TUE JUL 21 2015

.UPDATE...
AN MCV THAT MOVED EAST ACROSS NORTHWEST AND NORTH CENTRAL AR
DURING THE DAY WAS SERVING TO ORGANIZE THUNDERSTORMS AS IT ENTERED
NORTHEAST AR AT MIDEVENING. THIS STORMS WERE RIDING ALONG AN
EAST/WEST LOW LEVEL THETA-E GRADIENT. THIS THETA-E GRADIENT
BECAME SLIGHTLY LESS DEFINED AS IT EXTENDED SOUTHEAST TO THE
MEMPHIS METRO AT 9 PM.

PRIMARY CONCERNS WITH THESE STORMS THROUGH LATE EVENING REMAINS
HEAVY RAIN NEAR THE MCV CENTER /NORTHWEST LAWRENCE COUNTY AT
DISCUSSION TIME/ AND STRONG WIND CHANCES TO THE SOUTH OF THE
EASTWARD ADVANCING MCV.

FORECAST WAS RECENTLY UPDATED TO BOOST LATE EVENING AND OVERNIGHT
RAIN CHANCES FURTHER...MAINLY NORTH OF I-40.

DISCUSSION...
UPDATED FOR AVIATION DISCUSSION WITH 00Z TAFS.

PREV DISCUSSION... /ISSUED 355 PM CDT TUE JUL 21 2015/

DISCUSSION...

CURRENTLY A FRONTAL BOUNDARY EXTENDS ACROSS THE NORTH BORDER OF
THE FORECAST AREA WITH A SECONDARY BOUNDARY FARTHER TO THE SOUTH
NEAR MEMPHIS AND THE TN/MS BORDER. THE LESS DEFINED SOUTHERN
BOUNDARY NEAR THE TN/MS BORDER HAS BEEN THE MAIN FOCUS FOR
DIURNAL CONVECTION THIS AFTERNOON. ANOTHER AREA OF THUNDERSTORMS
IS OCCURRING SOUTH OF TUPELO. A HEAT ADVISORY REMAINS IN EFFECT
FOR SOUTHERN PARTS OF THE REGION...BUT AREAS IN THE SOUTHWEST ARE
MOST CLEARLY EXCEEDING THE THRESHOLD WHERE MORE SUNSHINE IS
OCCURRING. WILL LET THE ADVISORY EXPIRE THIS EVENING AS CONDITIONS
WILL NOT WARRANT AN ADVISORY AFTER TODAY UNTIL LATER IN THE WEEK.

FOR TONIGHT THROUGH THURSDAY...THE MAIN FRONTAL BOUNDARY WILL BE
STATIONARY NEAR THE NORTH BORDER OF THE FORECAST AREA. MULTIPLE
WEAK SHORTWAVES COMBINED WITH PLENTY OF MOISTURE WILL INCREASE THE
CHANCE OF SHOWERS AND THUNDERSTORMS OVER THE NEXT FEW DAYS. A FEW
STORMS COULD BE STRONG TO SEVERE THROUGH THE PERIOD. HIGHER STORM
CHANCES AND CLOUD COVER WILL KEEP TEMPERATURES LOW ENOUGH TO
PROVIDE A BREAK IN THE HEAT ADVISORY.

FRIDAY THROUGH EARLY NEXT WEEK...AN UPPER RIDGE WILL EXTEND IN
FROM THE WEST AND PUSH THE FRONTAL BOUNDARY FARTHER TO THE NORTH.
THIS WILL LOWER THE CHANCES OF STORMS AND BRING HIGHER HEAT
INDICES BACK INTO THE AREA. HEAT ADVISORIES MAY BE NEEDED AGAIN BY
THE END OF THE WEEK.
