At 900 AM EST...A surface low with a minimum pressure of 1010 mb,
or 29.83 inches of mercury, was located in southwestern Ontario
Province, Canada, with an occluded front trailing to the south
over Lake Erie before curving back further to the southwest over
Ohio. A cold front extended further southwest through the Ohio
Valley. Surface observations indicated favorably oriented westerly
winds continued across the Great Lakes region both ahead of and
behind the surface trough associated with the front. These
observations also indicated additional cold air advection was
following the front with temperatures remaining in the 20s to low
30s. National Weather Service Doppler radar indicated that the
cold air passing over long fetches of warmer lake water was
helping to contribute to multiple active bands of lake effect
snow. One such band was located west to east on the north side of
Lake Ontario, passing over Watertown, New York. Another band was
located west-southwest to east-northeast along the southern shores
of Lake Erie, passing over portions of western Upstate New York
just south of Buffalo. Additional, widespread snow continued east
of Lake Michigan along the western Lower Peninsula of Michigan and
south of Lake Superior in northern Wisconsin and the Upper
Peninsula of Michigan.

Bands of intense, heavy lake effect snow are forecast to continue
downwind of the Great Lakes through the weekend. This includes the
Upper and Lower Peninsula of Michigan, northeastern Ohio,
northwestern PA, and upstate New York. The highest, most
significant additional snowfall totals are expected in relatively
localized areas east of Lake Erie and northeast of Lake Ontario in
New York. Several feet of additional snowfall are possible, with
storm-total snowfall potentially exceeding 4 feet. The extreme
snow totals will be encouraged by embedded, more convective
snowfall with the potential for lightning and snowfall rates over
3 inches per hour at times. While not expected to be quite as
intense, another foot of snow is possible in favorable downwind
lakeshore locations of the Upper and Lower Peninsulas of Michigan.
Snowfall rates here will be heavy as well with upwards of 1-2
inches per hour possible. The snowfall should begin to subside
from west to east through the day and overnight Sunday as the
favorable wind trajectories and cold air advection over the Lakes
begins to end following the passage of a surface ridge and
subsequent warmer air behind it.

The next Storm Summary will be issued by the Weather Prediction
Center at 1000 PM EST. Please refer to your local National Weather
Service office for additional information on this event.
