   AREAS AFFECTED...CT/RI/MA/NH TO COASTAL MAINE
   
   CONCERNING...BLIZZARD 
   
   VALID 090907Z - 091330Z
   
   SUMMARY...BLIZZARD CONDITIONS WILL CONTINUE ACROSS PORTIONS OF NEW
   ENGLAND...ESPECIALLY RI/EASTERN CT AND CENTRAL/EASTERN MA TO
   SOUTHEAST NH/COASTAL MAINE...THROUGH THE EARLY MORNING HOURS
   /12-15Z/. SNOWFALL RATES OF 1-2 IN/HR WILL REMAIN COMMON WITH
   LOCALIZED RATES TO 3 IN/HR...ALTHOUGH THE HEAVIEST SNOWFALL WILL
   BEGIN TO TAPER BY DAYBREAK ACROSS WESTERN/SOUTHERN NEW ENGLAND.
   SIGNIFICANT NORTH/NORTHEAST WINDS WILL CONTRIBUTE TO BLIZZARD
   CONDITIONS WITH BLOWING AND DRIFTING SNOW.
   
   DISCUSSION...PER SATELLITE/SURFACE ANALYSIS...AN APPROXIMATE 974 MB
   SURFACE LOW IS CENTERED AROUND 80 MILES TO THE EAST-SOUTHEAST OF
   CAPE COD MA AS OF 09Z. A WELL-EVIDENT ROUGHLY 50-MILE WIDE CORRIDOR
   OF VERY HEAVY SNOWFALL CONTINUES TO OCCUR IN ASSOCIATION WITH THE
   DEFORMATION BAND/FRONTOGENETIC ZONE ON THE IMMEDIATE NORTHWEST
   PERIPHERY OF THIS CYCLONE. SINCE 0730Z...MEASURED WIND GUSTS TO
   50-60 KT HAVE BEEN NOTED AT A NUMBER OF OBSERVATION STATIONS
   INCLUDING FRYEBERG MAINE...BOSTON/LOGAN...AND MARTHAS
   VINEYARD...WITH A 67 KT WIND GUST MEASURED AT NANTUCKET MA AT 0722Z.
   WITH WSR-88D VWP DATA FROM BOSTON/TAUNTON AND GRAY MAINE SAMPLING
   55-70 KT NORTH-NORTHEASTERLY WINDS WITHIN THE LOWEST 1-2 KT...A
   SIMILAR POTENTIAL FOR VERY STRONG 50+ KT WIND GUSTS WILL ESPECIALLY
   PERSIST THIS MORNING ACROSS EASTERN PORTIONS OF MA/SOUTHEAST
   NH/MAINE. 
   
   CURRENT TRENDS/SHORT-TERM GUIDANCE SUGGESTS THAT THE DEFORMATION
   BAND AND ASSOCIATED HEAVIEST SNOWFALL THROUGH 12Z-15Z WILL CONTINUE
   TO SHIFT EASTWARD ACROSS FAR EASTERN PORTIONS OF CT/MA AND
   RI...WHILE OTHERWISE PERSISTING ACROSS SOUTHEAST NH/COASTAL MAINE. A
   GENERAL TREND OF GRADUALLY WARMING CLOUD TOPS HAS BEEN NOTED OVER
   THE PAST FEW HOURS IN IR SATELLITE IMAGERY...BUT EVEN SO...SNOWFALL
   RATES OF 1-3 IN/HR WILL REMAIN POSSIBLE THIS MORNING. FARTHER
   WEST/SOUTHWEST...SNOWFALL RATES ARE EXPECTED TO STEADILY TAPER
   THROUGH THE EARLY MORNING HOURS ACROSS THE REMAINDER OF MA/CT/LONG
   ISLAND.
