AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
947 AM CDT SUN JUN 26 2011

.UPDATE...
UPDATED FOR MINOR ADJUSTMENTS TO PRECIPITATION CHANCES AND SKY
COVER.

&&

.DISCUSSION...

CURRENT OUTFLOW BOUNDARY FROM NEAR CARUTHERSVILLE MISSOURI TO
SAVANNAH TENNESSEE HAS BECOME STATIONARY OVER THE PAST HOUR. THE
MOST ACTIVE PART OF THIS LINE HAS BEEN ACROSS LAKE AND OBION
COUNTIES AS A SECOND MCS DROPS SOUTHEAST OUT OF KENTUCKY.
EXTENDED DEFINITE POPS SLIGHTLY FARTHER WEST INTO THE BOOTHEEL OF
MISSOURI FOR THE REMAINDER OF THIS MORNING TO COVER THIS
COMPLEX...AND ALSO BUMPED UP AFTERNOON POPS ACROSS NORTHWEST
TENNESSEE AS THIS REGION WILL BE MOST FAVORABLE TO SEE CONTINUING
CONVECTION. SOUTH OF THE CURRENT OUTFLOW THE CAP HAS BEEN CLEARLY
EVIDENT WITH DETERIORATING MID HEIGHT CLOUD COVER. THUS HAVE
ADJUSTED CLOUD COVER AND WORDING IN THE FORECAST FOR MOSTLY SUNNY
SKIES THIS MORNING WITH MORE CUMULUS DEVELOPING THIS AFTERNOON
CAUSING PARTLY CLOUDY CONDITIONS. TEMPERATURES AND THE OTHER
FORECAST PARAMETERS APPEAR TO BE ON TRACK WITH NO CHANGES NEEDED
AT THIS TIME.

.PREV DISCUSSION... /ISSUED 602 AM CDT SUN JUN 26 2011/

PREV DISCUSSION... /ISSUED 500 AM CDT SUN JUN 26 2011/

AS OF 4 AM...TEMPERATURES ACROSS THE MIDSOUTH RANGE FROM THE LOW
70S IN THE TENNESSEE RIVER VALLEY TO THE LOW 80S ACROSS EASTERN
ARKANSAS. A LARGE COMPLEX OF SHOWERS AND THUNDERSTORMS IS MOVING
IN A SOUTHERLY DIRECTION ACROSS SOUTHERN ILLINOIS...WESTERN
KENTUCKY...AND EASTERN MISSOURI. THESE STORMS WILL BE MOVING INTO
WESTERN TENNESSEE OVER THE NEXT COUPLE OF HOURS.

TODAY...THE BEST CHANCES FOR SHOWERS AND THUNDERSTORMS WILL BE
ACROSS WESTERN TENNESSEE AND NORTHEASTERN MISSISSIPPI. ANY REMNANT
BOUNDARIES FROM THIS MORNINGS STORMS COULD BE THE FOCUS OF NEW
STORM DEVELOPMENT LATER THIS AFTERNOON. A FEW ISOLATED STORMS CAN
NOT BE RULED OUT ACROSS EASTERN ARKANSAS...THE MISSOURI
BOOTHEEL...AND NORTHWESTERN MISSISSIPPI. A COUPLE OF STORMS COULD
REACH SEVERE LIMITS WITH DAMAGING WINDS AND LARGE HAIL AS THE MAIN
THREATS. TEMPERATURES WILL BE MUCH HIGHER ACROSS SOUTHWESTERN
PORTIONS OF THE MIDSOUTH DUE TO THE LOWER CHANCES OF CLOUD COVER
AND RAIN.

THE RIDGE OF HIGH PRESSURE WILL STRENGTHEN OVERNIGHT
TONIGHT...AND WILL ELIMINATE ANY CHANCES FOR RAINFALL ACROSS THE
REGION. MONDAY LOOKS TO BE QUITE HOT...ESPECIALLY OVER THE
MISSISSIPPI DELTA. HEAT INDEX VALUES COULD APPROACH OR EXCEED 105
DEGREES ON MONDAY...SO THERE IS A CHANCE A HEAT ADVISORY WILL BE
NEEDED. AN ISOLATED AFTERNOON STORM OR TWO CAN NOT BE RULED OUT ON
MONDAY...HOWEVER THE CHANCES WERE TOO LOW TO MENTION IN THE
FORECAST.

ON TUESDAY...MODELS INDICATE THE RIDGE OF HIGH PRESSURE WILL
WEAKEN JUST ENOUGH TO ALLOW A COLD FRONT TO MAKE IT INTO THE
MIDSOUTH FROM THE NORTH. A SHORTWAVE TROUGH WILL ALSO APPROACH THE
REGION FROM THE WEST. THIS WILL ALLOW FOR THUNDERSTORM DEVELOPMENT
ALONG AND AHEAD OF THE COLD FRONT. A FEW STORMS COULD BECOME
SEVERE WITH DAMAGING WINDS AND LARGE HAIL AS THE MAIN THREATS. IT
IS POSSIBLE THAT THE CHANCES FOR RAIN WILL NEED TO BE INCREASED IN
LATER FORECAST PERIODS. HEAVY RAINS ARE ALSO POSSIBLE AS STORMS COULD
MOVE OVER THE SAME AREAS REPEATEDLY.

ONCE THE FRONT MOVES COMPLETELY THROUGH THE REGION TUESDAY
NIGHT...RAIN CHANCES WILL BECOME MINIMAL AGAIN. BEHIND THE
FRONT...TEMPERATURES WILL BE SLIGHTLY COOLER AND THE AIR WILL BE
MUCH DRIER. THE RIDGE OF HIGH PRESSURE WILL BUILD INTO THE REGION
AGAIN BY WEDNESDAY. HOWEVER...A LIGHT NORTHEAST WIND WILL HELP KEEP
TEMPERATURES COOLER AND HUMIDITY LEVELS DOWN.

FOR THURSDAY...TEMPERATURES WILL BEGIN HEATING UP AGAIN.
DUE TO LINGERING DRY AIR ACROSS THE REGION...HEAT ADVISORIES WILL
MOST LIKELY NOT BE NEEDED. HUMIDITY LEVELS WILL INCREASE AS A
SOUTH WIND RETURNS ON FRIDAY...SO HEAT INDEX LEVELS WILL NEED TO
BE MONITORED. RAIN CHANCES WILL BE MINIMAL THROUGH THE REST OF THE
FORECAST PERIOD DUE TO A STRONG RIDGE OF HIGH PRESSURE DOMINATING
THE WEATHER PATTERN.
