...A FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 915 AM CDT FOR
GILES...LAWRENCE AND WAYNE COUNTIES...

AT 719 AM CDT...NATIONAL WEATHER SERVICE DOPPLER RADAR CONTINUED TO 
INDICATE WIDESPREAD SHOWERS AND FEW THUNDERSTORMS ACROSS THE WARNED 
AREA. 

LOCATIONS IN THE WARNING INCLUDE BUT ARE NOT LIMITED TO PULASKI, 
LAWRENCEBURG, AND WAYNESBORO.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO CROSS
SAFELY. MOVE TO HIGHER GROUND.

MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR VEHICLE INTO
AREAS WHERE THE WATER COVERS THE ROADWAY. FLOOD WATERS ARE USUALLY
DEEPER THAN THEY APPEAR. JUST ONE FOOT OF FLOWING WATER IS POWERFUL
ENOUGH TO SWEEP VEHICLES OFF THE ROAD. WHEN ENCOUNTERING FLOODED
ROADS MAKE THE SMART CHOICE...TURN AROUND...DONT DROWN.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
333 AM CDT SAT MAY 2 2009

.DISCUSSION...
LOCAL WRF MODEL SHOWING FRONTAL ZONE FROM MEMPHIS TO NASHVILLE TO JACKSON
AND PUSHES IT SOUTHWARD TO NEAR THE TN/AL BORDER BY THIS EVENING.
WAVES FORM ON THE FRONT AS VARIOUS UPPER TROUGH RIPPLE ACROSS THE
AREA THIS WEEKEND. THUS WE ARE LIKELY TO HAVE PERIOD OF HEAVY RAINFALL
AND...OF COURSE...THE RESULTANT FLOODING GIVEN THE SOAKING WE HAVE
ALREADY HAD.

LOOKS LIKE THE LAST(IN A RELATIVE SENSE) OF THESE WAVE PASS BY ON
MONDAY MORNING ALLOWING A SHORT PERIOD OF DRYING OUT. BY DRYING
OUT I REFER TO THE REDUCTION OF RAINFALL.

HOWEVER...ANOTHER WAVE STARTS TO AFFECT US TUE NGT AS A SFC LOW
PRESSURE SYSTEM MOVES OUT OF THE PLAINS INTO THE OH/TN VALLEYS.
IF WE HAVE 24 HRS OF RELATIVELY LIGHT RAINFALL OUR LOW AREAS AND
STREAMS/RIVERS SHOULD HAVE SOME TIME TO DRAIN. THIS FEATURE PASSES US
ON WED BRING A BIT OF DRY AIR INTO THE AREA FOR WED AND PART OF THU.

THEN THE UPPER PATTERN BEGINS TO SHIFT A BIT FURTHER NORTH AS AN
UPPER RIDGE BUILDS OVER THE LOWER PLAINS. WE STILL GET SYSTEMS THAT
SWEEP THROUGH THE AREA BUT THEY GENERALLY KEEP MOVING.
