   Areas affected...portions of western New York

   Concerning...Heavy snow 

   Valid 062014Z - 070115Z

   SUMMARY...Lake-effect snow rates approaching 2 inches an hour are
   possible into the evening hours.

   DISCUSSION...A lake-effect snow band is ongoing across portions of
   Lake Ontario, which is impinging on Oswego County NY and is
   producing heavy snow based on the Fulton/Oswego County Airport ASOS.
   Some slight backing of the low-level winds from northwesterly to
   westerly, as shown by surface observations, will support a longer
   fetch of moisture across Lake Ontario. These backing winds may help
   intensify the ongoing snow band, as well as encourage this band to
   take on a slightly more west-to-east orientation over the next
   several hours. While at least one inch/hr rates are likely in the
   immediate term, snowfall rates approaching 2 inches/hr may be
   possible later this afternoon and evening.
