MESOSCALE PRECIPITATION DISCUSSION 0703
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
213 AM EST SAT DEC 26 2015
 
AREAS AFFECTED...FAR NORTHEAST MS...SOUTHERN TN...NORTHERN
AL...FAR NORTHWEST GA 
 
CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE 
 
VALID 260700Z - 261030Z
 
SUMMARY...HEAVY SHOWERS AND THUNDERSTORMS MOVING THROUGH FAR
SOUTHERN TN AND NORTHERN AL MAY RESULT IN SOME ADDITIONAL FLASH
FLOODING CONCERNS.

DISCUSSION...COOLING CONVECTIVE TOPS ARE NOTED OVER PARTS OF
NORTHWEST AL AND FAR SOUTHERN TN AS DEEP LAYER AND VERY MOIST
SOUTHWESTERLY FLOW CONTINUES TO INTERACT WITH A STATIONARY FRONT.
THE CONVECTION IS ALSO EMBEDDED WITHIN A SOMEWHAT DIVERGENT FLOW
PATTERN ALOFT AND THIS LARGER SCALE FORCING APPEARS TO BE
COMPENSATING FOR THE LACK OF INSTABILITY.

GIVEN SUCH HEAVY RAINFALL OVER THE LAST 24 HOURS ACROSS PORTIONS
OF THIS AREA...ANY ADDITIONAL RAINFALL WILL PROMOTE ADDITIONAL
POTENTIAL FOR FLASH FLOODING.

THE 00Z ARW AND 00Z NMMB SUGGEST SOME POTENTIAL FOR LOCALLY 1 TO 2
INCHES OVER THE NEXT FEW HOURS OVER SOUTHERN TN AND NORTHERN
AL...AND THE CONVECTIVE TRENDS WILL BE MONITORED FOR POTENTIALLY
SOME IMPACT TO NORTHWEST GA TOWARD DAWN WHICH THE 00Z ARW AND 00Z
NMMB SUGGEST.
