A storm with snow and ice on the front end will create hazardous travel and may lead to substantial airline disruptions in the northeastern United States.
The same storm set to produce a 1,200-mile swath of snow and ice over the Central states will extend its reach into the East this weekend.The wintry precipitation slated for this weekend follows a few inches of snow that fell over the central Appalachians Tuesday night and a batch of snow that may coat parts of eastern Maryland, Delaware and southern New Jersey Wednesday night.
Freezing rain will fall as far south as western North Carolina, and snow will extend as far to the east as Delaware, New Jersey, New York and New England from the storm this weekend.
For Washington, D.C., Baltimore, Philadelphia and other mid-Atlantic cities, this will be the first accumulating snow of the season. From New York City to Boston and much of southern New England, this will be the biggest snowstorm of the season so far.
Wintry precipitation will spread over the Appalachians, piedmont and eastern Great Lakes regions during Friday night.
Temperatures will be low enough to allow rain to freeze on colder surfaces from the Interstate 77 corridor of North Carolina to the I-81 corridor of Virginia late Friday night into Saturday.
Farther north, a mixture of freezing rain, sleet and snow will fall during the first part of the storm from eastern West Virginia, northern Virginia, northern Maryland and Delaware.

Areas from Pennsylvania to New Jersey and New York can expect mostly snow to spread over the area from west to east during late Friday night. The snow will reach much of New England by Saturday morning.
During much of Saturday, motorists will face slow and slippery travel from the northern mid-Atlantic states through New England. Road conditions will range from snow-covered to slushy or wet.
"The snow can come down hard at first, which could quickly cover roads, highways and sidewalks in the major cities from the I-99 and I-81 corridors to the I-95 cities of Philadelphia, New York City and Boston with this storm," according to AccuWeather Senior Meteorologist Henry Margusity.
The snow will be dry and powdery at first but will become heavy, wet and eventually slushy as the storm progresses.
Substantial airline delays are likely with the potential for a significant number of flight cancellations. Maintenance personnel will have to deice aircraft and clean snow from runways. Airline crews and aircraft may be displaced because of the vast expanse of the storm from the Rockies to the Midwest and Northeast.
Warmer air will flow in quickly later Saturday and Saturday night in coastal and southern areas, as well as locations west of the Appalachians. However, a wedge of chilly air may remain in the central and northern Appalachians, causing an extended period of ice. These areas will be at greatest risk for trees and power lines coming down.
Travel conditions will improve from south to north Saturday night into Sunday morning. However, some problems will remain. Locally gusty winds are possible in coastal areas. Areas of fog are possible as well.
"Areas along the I-95 corridor that had snow and/or ice will become a sloppy mess with slush and perhaps street flooding," according to AccuWeather Chief Meteorologist Elliot Abrams.
By Sunday morning, most areas in the Northeast will have warmed up enough for rain to fall. However, another wave of arctic air will begin to push across the Appalachians.
Cold air could catch up with the rain fast enough to bring a change to sleet and snow in the Appalachians during Sunday.
Regardless of a change to wintry weather on the back end, untreated areas of slush and standing water will freeze by Sunday evening over the mountains and along the Atlantic coast Sunday night.

Why
is the article directed to the Northeast while Bernie's video directed
to the midwest. Plus were is the great weather analysis videos that AW
used to post?

I'm
with you on the loss of the analysis videos--pretty much no reason to
go to Accuweather site any longer. I loved the in depth analysis with
maps, etc. The AW site is pretty much a copy of all the other sites now
only with even more frivolous videos.

I have a flight leaving DC at 7am on Saturday. Should I be worried about it getting cancelled?
Kenneth Kirby ·
Check
in early online and go to the gate at least 40 minutes before
departure. If flights cancel the night before they will be trying to
cram people onto your flight, and late arrivals to the gate might get
bumped.

Unfortunately
for where I live, it appears we're going to have the snow & ice
mix. I'd much rather have all snow than the mix, especially since
freezing rain is likely to be involved and that is the most dangerous
type of precipitation. I don't mind sleet so much, but I hate freezing
rain.

Chances
for a white Christmas appear to becoming slim to none for the east
coast as the tradition for the past 15 or so years has been a timely
blow torch and a yearly Christmas rainstorm just in time for the
holidays. Unfortunately this is an interesting phenomena that nobody
discusses, rather then use historical records as a whole I would like to
see the record of probabilities based on the 21st century. We will
notice quite quickly that many locations that had 75 percent probability
now have a 25 percent probability based on the 21st century record.

So
will Baltimore gets it first snow I know it says first accumulated
snow but on the forecast I have a feeling that Baltimore will not have a
first snow so are we??
