EVENT...HEAVY RAINS IN S CENTRAL MS
.
SATELLITE ANALYSIS AND TRENDS...DEEP CONVECTION RESULTING FROM EARLIER
OUTFLOW FROM CONVECTION EARLIER TODAY HAS PRODUCED HEAVY RAINS LAST
SEVERAL HOURS ACROSS N LA E THROUGH CENTRAL AND S MS. IN FACT SEVERAL
MERGERS AND OVERSHOOTING TOPS LIKELY STILL PRODUCING HEAVY RATES INVOF
SIMPSON COUNTY. MOISTURE ALSO SEEMS TO BE BEING PULLED FROM WESTERN GULF
REGION AND ALSO A CONNECTION TO TROPICAL STORM DOLLY.  THE BLENDED TPW
PRODUCT INDICATES PWATS RUNNING AROUND 2.1-2.2". COMBINED WITH SUCH
DEEP MOISTURE, MERGERS, AND CLOUD TOPS COOLING TO -80C WOULD EXPECT
RATES OF 1.5-2.5"/HR IN DEEPEST CONVECTION. WITH CAPES STILL IN EXCESS
OF 2000 J/KG WOULD EXPECT A FEW MORE HOURS OF HEAVY RAINS BEFORE DIURNAL
INFLUENCE WANES AND HEAVY RATES SHOULD DECREASE AS A RESULT.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.

SHORT TERM OUTLOOK VALID 2345-0245Z..MEDIUM CONFIDENCE FACTOR IN SHORT
TERM OUTLOOK...EXPECT MERGING CONVECTION TO PRODUCE 1-2"/HR+ RATES ACROSS
S CENTRAL MS/ NE LA FOR A FEW MORE HOURS BUT GENERALLY EXPECT REDUCED
DIURNAL INFLUENCE TO REDUCE HEAVY RAIN THREAT TOWARDS END OF OUTLOOK
PERIOD. A FEW MORE INCHES WHERE 2"+ TOTALS HAVE ALREADY OCCURRED COULD
PROLONG FF THREAT.
