AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
610 PM CDT MON AUG 15 2005

.DISCUSSION...HAVE ISSUED A QUICK UPDATE TO REFLECT THE CURRENT
TRENDS AND ALLOW THE GOING FORECAST TO BE A BIT MORE REPRESENTATIVE
WHERE ACTIVITY IS CURRENTLY GOING ON. HAVE INCREASED POPS OUT WEST
AND SW AND LOWERED POPS EAST. THE ACTIVITY ACROSS THE WESTERN CWA
HAS A BIT MORE GOING FOR IT AS IT HAS SOME UPPER JET SUPPORT AND
SOUTHERLY 850 MB FLOW WHICH IS ALLOWING THE COLD POOLS TO PROPAGATE
NORTHWARD AND DEVELOP NEW CELLS. ALL THIS ACTIVITY WILL GO ON FOR
ANOTHER 2 HRS OR SO...THEN DISSIPATE.

This locally intense rainfall caused about 20 homes to flood along Archer Ave. Additionally, several roads in this area were flooded by 1-2 feet of water which caused the roads to temporarily closed.
