…Moderate to heavy snow over the western portion of the Upper Peninsula
of Michigan from Monday night into Tuesday and lake-enhanced snow downwind
from Lakes Erie and Ontario Tuesday night into Wednesday…
…There is an Enhanced Risk of severe thunderstorms over parts of the
Central Appalachians/Mid-Atlantic on Monday…
A front extending from the Lower Great Lakes across the Ohio Valley and
then over the Lower Mississippi Valley/Southern Pains will move eastward
off the Eastern Seaboard and southward to the Gulf Coast by Tuesday
evening. The front will create showers and severe thunderstorms over parts
of the Ohio Valley to the Mid-Atlantic. Therefore, through Tuesday
morning, the SPC has issued an Enhanced Risk (level 3/5) of severe
thunderstorms over parts of the Central Appalachians/Mid-Atlantic. The
hazards associated with these thunderstorms are frequent lightning, severe
thunderstorm wind gusts, hail, and a few tornadoes.
Moreover, moderate to heavy lake-enhanced snow will develop over the
western portion of the Upper Peninsula of Michigan from Monday evening
into Tuesday. Showers and thunderstorms will develop over parts of the
northern Mid-Atlantic Monday evening into Tuesday as rain moves into parts
of the Northeast.
Meanwhile, as the system moves farther eastward on Tuesday, light to
moderate lake-enhanced snow will develop downwind from Lakes Erie and
Ontario and into the Northeast. Upslope snow will develop over parts of
the Central Appalachians overnight Tuesday into Wednesday morning. Rain
will also develop over parts of the Ohio Valley into the northern
Mid-Atlantic.
In the meantime, on Tuesday, a front moves onshore over the Pacific
Northwest and continues eastward to the Northern Plains to the Northern
Intermountain Region and then into the Great Basin by Wednesday evening.
On Wednesday, light snow develops over parts of the Northern Rockies and
rain at lower elevations. Also on Wednesday, upper-level energy off of the
California Coast will move onshore, producing light rain and embedded
thunderstorms over parts of Central California into the Great Basin.
