AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
813 PM CDT TUE AUG 4 2009

.DISCUSSION...

HUGE SQUALL LINE MOVING THROUGH MIDDLE TENNESSEE AND EXTENDING
INTO NORTHWEST TENNESSEE. THIS LINE WILL CONTINUE TO MOVE SOUTH TO
SOUTHEAST AFFECTING MANY AREAS ALONG THE TENNESSEE RIVER. OVER THE
PAST TWO HOURS...ADDITIONAL STRONG TO SEVERE THUNDERSTORMS WERE
DEVELOPING NORTHWEST OF THE MAIN LINE ABOUT 75 MILES SOUTH OF STL.

THE SEVERE THUNDERSTORM WATCH WILL CONTINUE UNTIL 11 PM AND MAY
NEED TO BE EXTENDED DEPENDING ON THE EVOLUTION OF THE
AFOREMENTIONED STORMS SOUTH OF STL. THE SAME AREAS CURRENTLY
EXPERIENCING HEAVY RAIN WILL LIKELY SEE ADDITIONAL HEAVY RAIN AND
POSSIBLE FLOODING. FLASH FLOODING AND STRAIGHT-LINE WINDS WILL BE
THE MAIN PROBLEMS WITH STORMS OVER THE REMAINDER OF THE NIGHT.

WILL RAISE OVERNIGHT TEMPERATURES FOR MUCH OF THE MIDSOUTH DUE TO
ABUNDANT LOW LEVEL MOISTURE REMAINING IN PLACE. COOLEST
TEMPERATURES WILL OCCUR DURING OR SHORTLY AFTER SHOWERS MOVE OVER
A PARTICULAR AREA...AND BE SHORT LIVED.
