MESOSCALE PRECIPITATION DISCUSSION 0010
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
140 PM EDT WED APR 17 2013
 
AREAS AFFECTED...ERN KY...FAR NW TN 
 
CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE 
 
VALID 171739Z - 172239Z
 
FLASH FLOODING IS POSSIBLE OVER PARTS OF EASTERN KY AND FAR
NORTHEAST TN DURING THE AFTERNOON.

THIS AREA RECEIVED LOCALLY HEAVY RAIN THIS MORNING AND THE
POTENTIAL EXISTS FOR ADDITIONAL CELLS TO MOVE BACK OVER THIS SAME
AREA DURING THE AFTERNOON.  

CONCERN IS GREATEST WHERE LOW LEVEL FLOW MEETS THE OUTFLOW
BOUNDARY AND THEN RIDES OVER THE COLD DOME NEAR THE SURFACE
LEADING TO SLOW CELL MOTION.  THEN SOME CELLS SHOULD EVENTUALLY BE
DIRECTED BACK TOWARDS THE AREA WHICH RECEIVED LOCALLY MODERATE TO
HEAVY RAIN THIS MORNING AS THE BOUNDARY STALLS AND BEGINS TO
RETURN IN RESPONSE TO INCREASING 850/700 MB FLOW.
