NESDIS IS CONTINUING TO ACCEPT APPEALS ON THE RETIREMENT OF THE SPENES
PRODUCT.  APPEALS CAN BE SUBMITTED BY EMAILING JOHN.SIMKO@NOAA.GOV
.
EVENT...UPDATE TO EARLIER SPE FOR HEAVY RAINS IN LA/AR/MS
.
SATELLITE ANALYSIS AND TRENDS...LATEST GOES SOUNDER CONTINUES TO SHOW HIGH
INSTABILITY TO THE W AND SW OF DEEPEST CONVECTION THAT IS ONGOING FROM
S AR SSE THROUGH CENTRAL/NE LA AND  S MS. GOES SOUNDER SHOWS BEST CAPES
APPROACHING 4000-5000 J/KG AND VIS IMAGERY SHOWS NEW DEVELOPMENT/MERGING
CONVECTION IN NE LA WHERE VERY EFFICIENT RAINFALL RATES ARE OCCURRING. VIS
IMAGERY DEPICTS OUTFLOW FROM EARLIER CONVECTION IN SE AR PROVING A FOCAL
POINT FOR NEW DEVELOPMENT IN NE LA POINTS ESE. WITH VIS IMAGERY SHOWING
OVERSHOOTING TOPS AND AND IR IMAGERY DEPICTING CLOUD TOPS AS COLD AS -72C
A MANUAL SATELLITE ESTIMATE PROVIDES 1.5"/30 MIN RATES. WITH BLENDED
TPW SHOWING PWATS IN THE 1.6-1.9" RANGE WOULD GENERALLY EXPECT 1-2"/HR
RATES WITH ISOLATED 2-3"/HR RATES POSSIBLE, ESPECIALLY IN CELL MERGERS.

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 2115-0115Z...MEDIUM TO HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...IN THE MORE IMMEDIATE TIME FRAME EXPECT HEAVY
RAINS TO CONTINUE ACROSS DISCUSSION REGION WITH 2-3"/HR RATES IN CELL
MERGERS AND UPWARDS OF 1-2"/HR RATES MORE GENERALLY. GIVEN SLOW STORM
MOTION WOULD EXPECT HIGH THREAT OF FF ISSUES TO REMAIN NEXT 3 HOURS.
