Some cool mesoscale boundaries in SW CT with rain and 44 in Fairfield and snow and 34 in Greenwich. Perhaps a coastal front right along LI Sound? Not often you see that large of a contrast across such a short distance.

SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 10/29/11 1543Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-763-8678 LATEST DATA USED: GOES-13 1515Z HANNA . LOCATION...NEW YORK...NEW JERSEY...PENNSYLVANIA...MARYLAND... . ATTN WFOS...OKX...ALY...PHI...BGM...CTP...LWX...PBZ... ATTN RFCS...NERFC...MARFC...OHRFC... . EVENT...HEAVY SNOW . SATELLITE ANALYSIS AND TRENDS...LATEST WATER VAPOR IMAGERY SHOWS THAT INTENSE VORTICITY CENTER/SHORTWAVE TROF HAS DROPPED INTO BASE OF LARGER SCALE TROF AND HAS NOW BEGUN LIFTING NE INTO S WV/W VA. BACKING AND HIGHLY DIFFLUENT FLOW AHEAD OF THIS SYSTEM HAS INCREASED LARGE SCALE ASCENT OVER THE REGION DURING THE LAST SIX HOURS AND CLOUD PATTERN HAS BEGUN TO TAKE ON CLASSIC COMMA HEAD WITH MID-LEVEL DEFORMATION AXIS EXTENDING ACROSS PA. IT APPEARS AS THOUGH DRY SLOT ASSOCIATED WITH ABOVE MENTIONED VORTICITY CENTER/JET STREAK WILL CONTINUE LIFTING NE THROUGHOUT THE AFTERNOON AND PUSH OVER THE DCA AREA AND TOWARDS S NJ BY LATE THIS AFTERNOON. THIS WILL LIKELY PLACE THE BEST COMBINATION OF FRONTOGENESIS AND INSTABILITY ALONG AN AXIS FROM CNTRL PA ENE TOWARDS E CNTRL PA AND INTO N NJ/S NY AND THE CATSKILLS REGION OVER THE NEXT THREE TO SIX HOURS. BELIEVE SNOWFALL RATES WILL LIKELY RANGE FROM 1.0-2.0"/HR WITH THOSE TYPES OF RATES MOST COMMON IN ANY FRONTOGENETICALLY ENHANCED WSW/ENE ORIENTED BANDS. CURRENTLY, THE MOST IMPRESSIVE OF THESE BANDS APPEARS TO BE ORIENTED FROM JUST N OF JST ENE TO VIC OF UNV AND THEN ENE TOWARDS VIC OF AVP.
