####018007560#### ACUS44 KWBC 181505 SCCNS4 Storm Summary Number 01 for Significant Great Lakes Lake Effect Snow Event NWS Weather Prediction Center College Park MD 1000 AM EST Fri Nov 18 2022 ...Intense, heavy bands of lake effect snow continue across the Great Lakes region this morning... Lake Effect Snow Warnings are in effect for downwind portions of Lake Erie and Ontario in Upstate New York. Winter Storm Warnings are in effect for downwind portions of Lake Superior in northern Wisconsin and downwind portions of Lake Michigan in the Lower Peninsula of Michigan. Winter Storm Watches are in effect for downwind portions of Lake Erie in northeastern Ohio and Lake Ontario in New York. Winter Weather Advisories are in effect surrounding the winter-weather related watches and warnings for downwind portions of Lake Superior in northern Wisconsin and the Upper Peninsula of Michigan, for downwind portions of Lake Michigan in the Lower Peninsula of Michigan, and downwind portions of Lake Ontario in Upstate New York. For a detailed graphical depiction of the latest watches, warnings and advisories, please see www.weather.gov 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. ...Selected preliminary Storm Total Snowfall in inches from 900 AM EST Wed Nov 16 through 900 AM EST Fri Nov 18... ...INDIANA...

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. Putnam $$
