FLOOD WATCH
NATIONAL WEATHER SERVICE MEMPHIS TN
1102 PM CDT TUE MAR 31 2015

...VERY HEAVY RAINFALL IN THUNDERSTORMS WILL LEAD TO AREAS OF
FLASH FLOODING OVERNIGHT...

.A FAVORABLE PATTERN FOR CONTINUED THUNDERSTORM DEVELOPMENT ALONG
A COUPLE OF OUTFLOW BOUNDARIES WILL CONTINUE OVERNIGHT. THE FIRST
BOUNDARY STRETCHED FROM LAUDERDALE COUNTY TENNESSEE SOUTHEAST INTO
FAR NORTHEAST MISSISSIPPI AS OF 0330Z AND THE SECOND FROM LAWRENCE
COUNTY ARKANSAS SOUTHEAST TOWARDS THE MEMPHIS METRO. THUNDERSTORMS
CONTINUE TO DEVELOP ALONG THESE BOUNDARIES AND ARE BEING FED AND
ENERGIZED BY A WESTERLY LOW LEVEL JET NOSING INTO THE BOUNDARIES
AROUND 5KFT. A RESERVOIR OF MODERATELY UNSTABLE AIR CHARACTERIZED
BY MUCAPES AROUND 1500 J/KG AND STEEP MID LEVEL LAPSE RATES AROUND
7.5 C/KM TO THE WEST IS FEEDING IN ON THE LOW LEVEL JET AND
ALLOWING FOR SOME STORMS TO PRODUCE VERY HEAVY RAINFALL.

IN ADDITION...THE LOW AND MID LEVEL SHEAR PATTERN IS FAVORABLE FOR
BACKBUILDING AND TRAINING STORMS WHICH WILL LIKELY FOCUS FLASH
FLOODING ALONG THE SLOW MOVING OUTFLOW BOUNDARIES.
