   Areas affected...portions of New York directly downstream of Lake
   Ontario

   Concerning...Heavy snow 

   Valid 010203Z - 010600Z

   SUMMARY...Heavy snow -- falling at rates of up to 2" per hour --
   will continue eat of Lake Ontario, with a slight northward shift in
   the main snow band expected over the next couple of hours.

   DISCUSSION...Latest radar data shows heavy snow continuing across
   portions of upstate New York east of Lake Ontario.  The heaviest
   snow has been occurring near and south Watertown, and eastward into
   the Tug Hill area.  However, recent trends indicate that the main
   band is shifting/reforming slightly to the north.  This is likely
   occurring in response to very slight backing of the 0 to 3km flow --
   as depicted over the past few hours per the Fort Drum (KTYX)
   WSR-88d.  As such, it appears that the area of heaviest snowfall may
   gradually become focused near and north of Watertown (and areas
   eastward) over the next few hours.
