WEATHER THURSDAY FEB 15 2024 PAC NW RAINS , NE COLD AND FAIR MOST OF THE NATION TODAY

.A Pacific storm system pushing into the West Coast will bring locally
heavy rain near the coast, and heavy high elevation snowfall into the
Intermountain West over the next couple of days...
Hard hitting storm system to produce accumulating snowfall across the
Great Lakes today and into the Interior Northeast Thursday night and
Friday morning.
.Next round of snow expected to quickly spread from the central Plains
and Ohio Valley on Friday, then into the Central Appalachians and
Mid-Atlantic Friday night into Saturday morning...
A Pacific storm system is ushering in a stream of precipitation into the
West Coast and Intermountain West the next couple days. Meanwhile, a
sufficiently cold air-mass anchored in place by high pressure over
southwest Canada will force a frontal boundary to remain stationary over
the central and northern Rockies through Friday. Coastal areas of the
Pacific Northwest and the valleys of the Intermountain West can expect
periods of rain, while mountain ranges such as the Oregon Cascades, the
Olympics in western Washington, and on east into the heart of the Northern
Rockies witness heavy snow today.
To the east, a low pressure system tracking through the Great Lakes today
is generating showers to the south of its track, while a swath of
moderate-to-heavy snow envelopes southern Wisconsin and northern Michigan.
This storm system is quite progressive, quickly finding itself tracking
over Lake Ontario by Thursday evening. Showers are likely in the central
Appalachians, while periods of snow ensue over the Interior Northeast. By
Thursday night, northwesterly winds escorting in a cold, Canadian air-mass
will rush over the Great Lakes and trigger lake effect snow showers
downwind of Lakes Erie and Ontario Thursday night and linger into the day
on Friday. Snow showers will linger across parts of New England on Friday,
but gradually dissipate as the storm tracks farther into the northwest
Atlantic. In total, over 6 inches of snow is expect in parts of the
Michigan U.P., the northern half of Michigan's Mitten, and across northern
New York. More specifically, the Tug Hill Plateau and neighboring
locations could see over a foot of snow by the time snow concludes Friday
morning. In addition, gusty winds are also an impact from this storm
system, as evident by the Wind Advisories in place over northern Ohio for
today and both western and the Southern Tier of New York between Thursday
afternoon and Friday morning.
By Thursday night, a new wave of low pressure will be taking shape over
the Central Plains with a swath of moderate-to-heavy snow setting up over
northern Nebraska and southern South Dakota. The storm tracks quickly into
the mid-Mississippi river Valley by late Friday morning with periods
anticipated across northern Missouri and central Illinois, while rain
showers and isolated thunderstorms make for a damp day from the ArkLaTex
on east into the Tennessee Valley by Friday afternoon. By Friday night,
the storm will restrengthen as it reaches the Mid-Atlantic with an axis of
moderate-to-heavy snow bringing light snowfall accumulations to the Ohio
Valley Friday evening, then over the northern Mid-Atlantic Friday night
into early Saturday morning. The Potomac Highlands of West Virginia and
Allegheny Mountains from western Maryland to south-central Pennsylvania
have the best chances of seeing snowfall totals surpass 4 inches Friday
night, but anywhere from 1-3" of snow is possible from the mid-Mississippi
Valley on Friday and the Ohio Valley Friday evening, to the DC/Baltimore
metro areas on north to the Philadelphia metro area early Saturday
morning. Some hazardous travel is possible in portions of these regions,
particularly on untreated roads Friday night into Saturday
