Mesoscale Discussion 2068

Areas affected...Northeast OH...Western PA...Extreme Western
NY...Extreme Western MD...Northern WV Panhandle.

Concerning...Blizzard=20

Valid 231249Z - 231645Z

SUMMARY...Heavy snowfall and strong winds will result in blizzard
conditions across portions of northeast OH and western PA over the
next few hours.

DISCUSSION...An intense mid-latitude cyclone continues to push
eastward across the OH Valley, accompanied by very strong winds and
frigid temperatures. Latest surface analysis places the surface low
associated with this cyclone just east of south Lake Huron. An
attendant cold front stretches southeastward from this low through
southwestern Ontario, western PA, and the eastern WV Panhandle. The
heaviest snowfall rates over the past hour or so have occurred from
the CLE vicinity southeastward into west-central PA, where where
ascent along the front aligns with deeper large-scale ascent. This
area of heavy snow is expected to shift northeastward into far
northeast OH and more of western PA. Snowfall rates of 1" to 2" per
hour are possible within this band.=20

In addition to the heavy snowfall, strong winds are resulting in
blizzard conditions for much of northeast OH and western PA. These
blizzards conditions are occurring even in areas west of the band of
heavy snowfall, where persistent strong winds are resulting in
reduced visibility due to blowing snow. As a result, blizzard
conditions are expected to continue across northeast OH and western
PA over the next several hours. Adjacent areas of extreme western
NY, extreme western MD, and central PA could experience
near-blizzard conditions.
