SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 01/13/13 1603Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES-13 1515Z CW .

SATELLITE ANALYSIS AND TRENDS...WV/IR SATELLITE SHOW AN AREA OF ENHANCED CLOUDS TRACKING SW TO NE FROM NE AR/W TN/SE MO TOWARDS WRN KY/S IN. AS POTENT SHORTWAVE SLOWLY LIFTS NE FROM ERN TX/WRN LA MOISTURE AND PRECIPITATION WILL CONTINUE TO LIFT NNEWD SPREADING MOD TO HEAVY RAINS ACROSS THE DISCUSSION AREA. SEVERAL EMBEDDED WAVES ARE NOTED ON LATEST VIS SATELLITE IMAGERY...COUNTING AT LEAST 5 STRETCHING FROM WRN KY THROUGH NE LA. THESE IMPULSES LIKELY WILL AID IN PUMPING IN HIGHER MOISTURE AND ENHANCE VERTICAL MOTION LEADING TO PERIODS OF HEAVY RAINS OVER THE NEXT SEVERAL HRS. . 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 1600-2100Z...MEDIUM-HIGH CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...AS MID AND UPPER-LEVEL ENERGY SPREADS NNE TX/LA DOWNSTREAM OF VERY AMPLIFIED TROUGH AXIS...MOD TO HEAVY RAINS SHOULD GRADUALLY SPREAD ACROSS PORTIONS OF WRN KY/SRN IN OVER THE NEXT 6 HRS. EMBEDDED IMPULSES COULD LEAD TO BRIEF PERIODS OF HEAVY DOWNPOURS FOR SOME LOCALIZED AREAS. GIVEN THE TRAINING NATURE AND COPIOUS AMOUNT OF MOISTURE ASSOCIATED WITH THIS SYSTEM...SOME AREAS MAY RECEIVE 2-3" OF RAINFALL OVER THE NEXT 6 HRS. . ....NESDIS IS A MEMBER OF 12 PLANET.... .
