SATELLITE ANALYSIS AND TRENDS...LINE OF THUNDERSTORMS EARLIER HAS SET THE
STAGE FOR THE POTENTIAL FOR VERY HIGH TOTALS...ESPECIALLY IN AN URBAN AREA
WHERE FF THREAT IS EXACERBATED.  EARLIER LINE PRODUCED UP TO MANUAL SATELLITE
ESTIMATES 4" JUST OFF THE BROOKLYN COAST OVER WATER...WITH SOME 1-2" AMOUNTS
OVER NYC. HOWEVER...DUE TO THE CONVECTION THE OUTFLOW LINE HAS REMAINED NEARLY
E-W WHERE CELL MOTION WILL CAUSE FURTHER TRAINING OF CELLS.  CURRENT VIS LOOP
SHOWS A LINE OF THUNDERSTORMS WITH MULTIPLE OVERSHOOTING TOPS FROM E BUCKS
COUNTY PA TO JUST SOUTH OF LONG ISLAND.  THESE CELLS HAVE VERY COLD TOPS (-
65C) AND ARE CAPABLE OF RAIN RATES OF 2.0"-2.5"/HR BASED ON GOES SOUNDER PW
VALUES OF 1.7" WITHIN THE VICINITY.  NJ COUNTIES OF MIDDLESEX AND SOMERSET
COUNTIES HAVE SEEN SOME SIGNIFICANT TRAINING IN THE LAST 2 HOURS...WITH WHAT
APPEARS TO BE 2 OVERSHOOTING TOPS CURRENTLY IN S SOMERSET COUNTY...THESE CELLS
WILL TRACK ACROSS STATEN ISLAND INTO BROOKLYN AND QUEENS IN THE NEXT HOUR WITH
THESE RATES EXPECT AN ADDITIONAL 1-2" ALONG THE LINE...WITH ISOLATED 2.5"
WHERE MERGERS OCCUR.   
.
1 HOUR HYDRO-ESTIMATOR TOTALS ARE ON AWIPS UNDER 1 HOUR AUTO SPE.
