A storm over southeastern Canada will move eastward to far eastern Canada
by Friday morning. The system will produce heavy lake-enhanced then heavy
lake-effect snow downwind from Lakes Erie and Ontario on Thursday and
Friday. Additionally, in the wake of the storm, light to moderate
lake-effect snow will develop over parts of the Upper Peninsula of
Michigan and the west coast of the Lower Peninsula of Michigan on Thursday
and Friday. Further, moderate to heavy snow will be created on Thursday
over parts of New England. By Friday, scattered light snow will be over
New England and then the snow will end by Friday evening.  Furthermore,
light to moderate snow will develop over parts of the Central Appalachians
on Thursday and Friday.

Moreover, the strong arctic cold front will sweep across the Mid-Atlantic
and the Northeast on Thursday. The boundary will create snow squalls
accompanied by intense bursts of heavy snowfall and gusty winds, producing
dangerous travel conditions due to whiteouts and icy roads.  In addition,
wind gusts up to 80 mph will spread into the Central Appalachians,
Mid-Atlantic, and Northeast on Thursday. These winds would cause power
outages, down tree branches, and result in hazardous commutes.

Moreover, after the storm, high pressure over the Northern Plains will
move southeastward to the Tennessee Valley by Saturday. The high pressure
will usher in cold temperatures over parts of the Ohio Valley and the
Mid-Atlantic, bringing temperatures of 10 to 20 degrees below average.

Meanwhile, return flow off the Gulf of Mexico will create scattered
showers and thunderstorms over parts of the Central Gulf Coast on
Thursday. On Friday, scattered showers and thunderstorms will develop over
parts of the Southern High Plains.

Elsewhere, lingering stagnant air conditions will be over parts of the
Pacific Northwest, leading to areas of dense fog and poor air quality.
However, an approaching front over the Eastern Pacific will usher moisture
into the Pacific Northwest, creating light rain over parts of the
Northwest Coast late Friday night into Saturday.
