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

Concerning...Snow Squall=20

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.
