WIDESPREAD RAIN CONTINUES TO FLOW UP THE MISSISSIPPI RIVER VALLEY
THIS MORNING. THIS IS AHEAD OF A RATHER STRONG UPPER LEVEL TROUGH
AND ITS ASSOCIATED COLD FRONT. AT EARLY MORNING...THE FRONT
STRETCHED FROM SOUTHEAST MO THROUGH WESTERN AR INTO NORTHEAST TX.
THE FRONT WILL MOVE SLOWLY THROUGH THE MIDSOUTH TODAY AND TONIGHT.

RAIN TOTALS HAVE BEEN MOUNTING UP ALONG THE MISSISSIPPI RIVER...AND
THINK MUCH OF OUR CWFA COULD RECEIVE AN ADDITIONAL 2 TO 3 INCHES
BEFORE THIS EVENING. HOWEVER...THREE HOURS TOTALS INDICATED BY 88D
AND SURFACE REPORTS THUS FAR HAVE REMAINED BELOW FLASH FLOOD
GUIDANCE VALUES. IN ADDITION...NO REPORTS OF FLOODING HAVE BEEN
RECEIVED. THUS WITH THE RECENT DRY SPELL...WILL NOT ISSUE A FLASH
FLOOD WATCH ATTM. WILL MENTION RAIN HEAVY AT TIMES.

SPC HAS MUCH OF CWFA ALONG AND EAST OF THE MISSISSIPPI RIVER
OUTLOOKED FOR SLIGHT RISK OF SEVERE WEATHER. THINK THE BEST CHANCE
WILL BE EAST OF MEMPHIS AND PROBABLY CLOSER TO THE TENNESSEE
RIVER AHEAD OF THE MAIN RAIN AREA LATE THIS MORNING AND
THIS AFTERNOON. ISOLATED SEVERE STORMS ARE POSSIBLE MAINLY WITH
DAMAGING WIND GUSTS.

DRIER AIR WILL SPILL INTO THE MIDSOUTH TONIGHT AND SATURDAY WITH
DEWPOINTS FALLING INTO THE 60S. REINFORCING AND COOLER HIGH
PRESSURE WILL ARRIVE SUNDAY NIGHT. AFTER TODAY AND THIS EVENING...
THINK DRY WEATHER WILL PREVAIL INTO MUCH OF NEXT WEEK.
