MESOSCALE DISCUSSION 1665
NWS STORM PREDICTION CENTER NORMAN OK
0155 PM CDT SAT JUL 29 2006

AREAS AFFECTED...EASTERN MS/NORTHERN AND CENTRAL AL/WESTERN GA

CONCERNING...SEVERE THUNDERSTORM POTENTIAL...HEAVY RAINFALL 

VALID 291855Z - 292100Z

STRONG/ISOLATED SEVERE THUNDERSTORMS WILL CONTINUE TO DEVELOP
THROUGH MID/LATE AFTERNOON ACROSS EASTERN MS/NORTHERN AND CENTRAL AL
INTO WESTERN GA. DAMAGING WINDS/SOME LARGE HAIL AND LOCALLY HEAVY
RAINFALL WILL ALL BE POSSIBLE THROUGH EARLY EVENING. 

SATELLITE/VOLUMETRIC RADAR DATA DEPICTS MCV MOVING SOUTHEASTWARD
FROM WESTERN TN INTO FAR NORTHERN MS/NORTHWEST AL. TIED TO THIS
FEATURE...COMPOSITE OUTFLOW BOUNDARY CONTINUES TO SAG SOUTHWARD
ACROSS THE FAR NORTHERN PORTIONS OF AL/MS/GA. THIS BOUNDARY /AND
DIFFERENTIAL HEATING ALONG IT/ WILL CONTINUE TO FOSTER
UPLIFT/PARCELS REACHING THEIR LFC AND A MODEST FOCUS...WITH
INCREASING TSTM COVERAGE IN A WEAKLY CAPPED AIRMASS ACROSS MUCH OF
AL/EASTERN MS/WESTERN GA. LOCAL WSR-88D VWP DATA/RUC DIAGNOSTICS
SUGGEST THE MCV MAY BE LOCALLY ENHANCING VERTICAL SHEAR
SOMEWHAT...ALTHOUGH THE STORMS SHOULD REMAIN FAIRLY PULSE IN NATURE.
IN ADDITION TO THE POSSIBILITY OF DAMAGING DOWNBURSTS/SOME LARGE
HAIL THROUGH EARLY EVENING...SUFFICIENTLY HIGH PW ENVIRONMENT/SLOW
STORM MOTIONS WILL ALSO FAVOR LOCALLY HEAVY RAINFALL.
