Heavy lake-effect snow downwind from Lakes Erie and Ontario; moderate
to heavy lake-effect snow over the eastern U.P. of Michigan.

Light to moderate snow over parts of the Northern High Plains on
Wednesday.

There is a Marginal Risk of severe thunderstorms over parts of
Florida.

A front moving off of Florida will create showers and strong to severe
thunderstorms over Florida. Therefore, the SPC has issued a Marginal Risk
(level 1/5) of severe thunderstorms over parts of Florida through Tuesday
morning. The hazards associated with these thunderstorms are frequent
lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. By
Tuesday, the showers and thunderstorms move off the southern tip of
Florida as the front moves offshore.

Meanwhile, upper-level energy over the Ohio Valley into the Northeast will
move off the Northeast Coast by Tuesday morning. Additionally, upper-level
energy will move over the Great Lakes into the Northeast on Tuesday.
Furthermore, a second front moving south and eastward from Central Canada
will move over parts of the Northern Plains/Upper Mississippi Valley on
Monday evening, moving to the Great Lakes by Tuesday and to the Northeast
Coast by Wednesday. The energy, and later the front, will aid in creating
lake-effect snow downwind from the Great Lakes through Wednesday. With the
front, moderate to heavy snow will develop over the eastern U.P. of
Michigan Tuesday evening into Wednesday. Additionally, heavy lake-effect
snow develops downwind from Lakes Erie and Ontario. Further, moderate snow
will develop over the higher elevations of the Northeast through Wednesday
evening and snow showers over parts of the Ohio Valley and the Central
Appalachians through Tuesday afternoon.

Along the western end of the front moving out of Canada, snow will develop
over parts of the Northern Rockies/Northern High Plains overnight Tuesday
into Wednesday.

Moreover, an upper-level low over the Southern California/Southwest will
slowly move eastward to the Southern High Plains by Wednesday evening. The
energy will produce snow and lower-elevation rain over parts of the
Southwest and Southern Rockies, lingering through Wednesday afternoon. As
the energy moves out of the Rockies, showers and thunderstorms will
develop over parts of the Southern Plains. Farther north, a dissipating
front moves near the Pacific Northwest on Wednesday into Wednesday
afternoon and will produce rain over parts of the Northwest.
