...Snow over the Great Lakes, Ohio Valley, and Central
Appalachians...

High pressure extends from the Great Basin to the Southern Plains
as an upper-level trough over the Great Lakes/Ohio Valley slowly
moves off the Northeast Coast by early Monday morning. The
upper-level energy flowing over the Great Lakes will produce
lake-effect snow downwind from the Great Lakes and over the Ohio
Valley, with the heaviest amounts downwind from Lakes Erie and
Ontario, as well as the Central Appalachians. As the energy moves
away, lighter snowfall amounts will fall downwind from the Great
Lakes from Monday evening into Tuesday.

Furthermore, a front lingering over or near Florida will develop
rain and showers along parts of the peninsula through Tuesday.
Also, an upper-level energy moving over southern Texas will
trigger light rain over the region from early Monday morning into
Tuesday evening.

Overnight Monday, a front will move out of southern Canada into
the Upper Great Lakes, producing snow and rain over the Great
Lakes/Ohio Valley on Tuesday.

Meanwhile, weak onshore flow off the Pacific will produce coastal
rain and higher-elevation snow over parts of the Pacific Northwest
and the Northern Intermountain Region through Tuesday morning.
Lastly, upper-level impulses will trigger lower-elevation rain and
higher-elevation snow over parts of the Northern Intermountain
Region into the Northern Rockies/Northern High Plains from Sunday
evening into Tuesday.
