EVENT...HEAVY RAINFALL POSSIBLE NEXT FEW HRS
.
SHORT TERM OUTLOOK VALID 1140-1420Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...OVER THE PAST COUPLE OF HRS ACTIVITY ALONG
OUTFLOW BOUNDARY OF LEADING EDGE OF EARLIER MCC HAD BEEN GRADUALLY
WEAKENING AS IT TRACKED EWD.  THE FORWARD PROPAGATION OF THIS LINE
HAS BEEN SLOWING AND IS NOW MOVING INTO AN AREA OF BROAD SRLY LLVL
FLOW ACROSS SRN AL/WRN FL.  FIRST FEW VISIBLE STLT IMAGES FROM GOES-13
AND GOES-14 (SRSO 1-MIN IMAGERY) SHOW NUMEROUS OVERSHOOTING TOPS WITH
ACTIVITY ACROSS SERN MS THAT IS BEGINNING TO INTERSECT THIS SRLY FLOW.
ADDITIONAL CU ARE ALSO GRADUALLY BUILDING OVER THE GULF OF MEXICO NEAR
THE COASTLINE AND ARE SEEN TRACKING NWD.  BOTH GOES SOUNDER AND SPC
MESO-ANALYSIS SUGGEST CAPE VALUES NEAR 3000 J/KG WITHIN THIS BROAD
LLVL CONFLUENT FLOW AND HAVE BEEN GRADUALLY SHIFTING NWD WITH TIME.
CONCERN IS THAT THERE EXISTS THE POTENTIAL FOR AN INCREASE IN AREAL
COVERAGE AND INTENSITY OVER THE NEXT FEW HRS WITH RAIN RATES NEAR 2.0"/HR.
THE SLOWER FORWARD SPEED MAY ALSO LEAD TO LOCALLY HIGHER RAINFALL AMOUNTS.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
