SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 01/23/13 0023Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES-13: 2345Z VOGT . LOCATION...NEW YORK...NW PENNSYLVANIA...EXT NE OHIO... . ATTN WFOS...ALY...BGM...BUF...CLE... ATTN RFCS...NERFC...MARFC...OHRFC... . EVENT... TRANSITION TO MULTIPLE BANDS ACROSS LAKES ERIE/ONTARIO . SATELLITE ANALYSIS AND TRENDS... SINCE THIS AFTERNOON, THE SINGLE LAKE-EFFECT SNOW BAND THAT WAS SET UP ACROSS LAKE ONTARIO HAS BEEN SHIFTING SOUTH. DURING THIS MVMT, THE CONNECTION FROM LAKE HURON ACROSS LAKE ONTARIO WAS NOT AS STRONG IN SATELLITE IMAGERY AS IT HAS BEEN AT PTS OVER THE PAST 24-36 HOURS... THAT BEING SAID, IT APPEARS THAT THE SINGLE BAND CONTINUES TO WEAKEN... IN ITS WAKE, MULTIPLE BANDS ARE SETTING UP OFF OF LAKE ERIE AND POSSIBLE WRN LAKE ONTARIO, WHICH MAY BE DUE TO THE JET MAX THAT IS ROUNDING THE BASE OF THE UL TROF AND MOVING ITS WAY THROUGH OHIO/WV. THERE STILL SEEMS TO BE GOOD MOISTURE TRANSPORT FROM LAKES HURON/MICHIGAN INTO LAKES ERIE/ONTARIO... SO ISOLATED 1-2"/HR SNOWFALL RATES ARE STILL POSSIBLE WITHIN THE MULTIPLE BANDS. . SHORT TERM OUTLOOK VALID 0025-0430Z... MEDIUM CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...EXPECT THE SINGLE LES BAND TO CONTINUE TO SLIGHTLY WEAKEN AS MULTIPLE BANDS SET UP ACROSS LAKES ERIE/ONTARIO. 1-2"/HR SNOW RATES ARE POSSIBLE BUT WILL ALSO LIKELY WEAKEN THROUGHOUT THE DISCUSSION PERIOD. . ....NESDIS IS A MEMBER OF 12 PLANET.... .
