   Areas affected...Southwest NY...northwest PA...far northeast OH

   Concerning...Snow Squall 

   Valid 030241Z - 030545Z

   SUMMARY...Conditions appear favorable for snow-squall conditions in
   the lower Great Lakes vicinity. Rapid visibility reductions are
   possible with bursts of moderate to heavy snow.

   DISCUSSION...Latest KBUF/KCLE radar data show an organizing snow
   band extending from southwestern NY into far northeastern OH. This
   band is organizing along the wind shift accompanying a
   southeastward-advancing arctic cold front. Overall environmental
   conditions appear favorable for the persistence and perhaps
   intensification of this band into a snow squall during the next few
   hours. For additional details on these environmental conditions,
   please reference MCD 128. The one limiting factor is dry
   boundary-layer conditions with eastward extent into central PA and
   NY. However, sufficient boundary-layer moisture is evident
   immediately ahead of the developing snow band to support rapid
   visibility reductions in bursts of moderate to heavy snow.
