Strong Winds, Snow, Cold Air, Severe Storms Expected in Midwest and East; Chilly Pattern May Linger Thanksgiving Week
A potent storm system will bring strong winds, heavy rain, snow and possibly severe storms to the Midwest and East late this week while ushering in cold temperatures that may stay in place through Thanksgiving.
Strong low pressure moves through the Great Lakes this weekend with cold air diving southward behind the storm.
This storm system could cause delays for those getting an early start on Thanksgiving travel this weekend. Details on any travel impacts for Thanksgiving week itself are too early to pinpoint this far out in time(MORE: Winter Storm Central)
Here's an overview of what to expect from the late-week storm followed by an overview of Thanksgiving week.
Late-Week Storm: Cold Plunge Follows Midwest, Eastern Storm
Sometimes, the transition to a new weather pattern is accompanied by a significant storm.
In this case, a sharp jet stream plunge will induce a low-pressure system to strengthen quickly over the Great Lakes and eastern Canada Friday into Saturday, producing wind-whipped snow in the colder air and heavy rain in the warmer air ahead of the cold front. There is also a risk of severe thunderstorms on the warm side of this weather system.
The Great Lakes snowbelts may see heavy snow, and snow or a wintry mix is also possible in parts of the interior Northeast from this system Friday into the weekend.
Friday
- Snow, or rain changing to snow, along with gusty winds, may affect parts of the upper Midwest and the western and northern Great Lakes regions.
- Showers and thunderstorms should spread through the southern Great Lakes, Ohio Valley, Mississippi Valley and South. Severe storms with damaging winds will be possible in the Ohio and Mississippi valleys.
- A wintry mix may develop in upstate New York and interior New England by Friday night.
96L Southwest of the Azores May Become Subtropical Storm Sean
A non-tropical low-pressure system with the potential to develop into a subtropical storm was located in the east-central Atlantic about 600 miles southwest of the Azores Islands on Monday morning. This system was designated Invest 96L by NHC over the weekend. The low is moving slowly northeastward towards the Azores, which is the only land area that needs to be concerned with this storm.
Conditions were marginally favorable for development on Monday, with moderate wind shear of 15 knots and ocean temperatures of 24°C (75°F). These temperatures are probably too cool to allow transition of 96L to a fully tropical storm, but may be warm enough to allow 96L to become a subtropical storm deserving of a name. Satellite loops on Monday morning showed that 96L was already beginning to take on some characteristics of a subtropical storm, with a large area of heavy thunderstorms located in a curved band more than 100 miles from the cloud-free center of circulation. In their 7 am EST Tropical Weather Outlook, NHC gave 96L 2-day and 5-day odds of development of 30% and 50%, respectively. The next name on the Atlantic list of storms is Sean.

Icy mix may trigger slick Monday morning commute in central Appalachians
Just enough snow and ice could occur across a portion of the northeastern United States to trigger travel headaches during the Monday morning commute.
Roads and sidewalks have become sufficiently cold in the wake of an Arctic push for even a light wintry mix to stick and create a slick glaze on untreated surfaces, especially at night.
Travelers may need to allot extra time to reach their destinations and should use caution over bridges and overpasses.
The system that spread a chilly rain and areas of snow and sleet across the lower Great Lakes region on Sunday will push eastward to start the new week.
A mix of snow and sleet arrived in the northern mid-Atlantic and interior Northeast on Sunday night, and is expected to last into Monday, AccuWeather Lead Long-Range Meteorologist Paul Pastelok said.
“While a heavy accumulation is not anticipated, just enough snow and sleet or freezing rain may occur to glaze some roads and sidewalks,” AccuWeather Senior Meteorologist Alex Sosnowski said.
A large portion of Pennsylvania as well as western and central New York state, and the high terrain of West Virginia and Maryland could face a slippery Monday morning commute.

Thanksgiving outlook: Brutal cold, snow to blast Midwest as a storm may eye the East
While warmth builds in the Southwest, re-surging cold air may trigger frequent snow in the Great Lakes and help spin up a storm along the East Coast around Thanksgiving Day.
Following a storm and shot of cold air that sweeps across the northern part of the nation into this weekend, there is the potential for very cold air to take root over the Midwest during the long Thanksgiving weekend.
"If early indications are correct, some locations may be buried under feet of lake-effect snow, while gusty winds sweep cold air from the northern Plains to the Gulf Coast, Appalachians and eventually the Atlantic Seaboard," according to AccuWeather Senior Meteorologist Brett Anderson.
It is during that press of arctic air, when another storm may come about with a swath of steady rain, ice and snow in the Northeast.
At the jet stream level, a piece of the polar vortex may break loose and settle near the Great Lakes. The jet stream is a high speed river of air at the level where jets cruise at.
The polar vortex is a storm around the same level of the atmosphere as the jet stream. Usually this storm hangs out near the Arctic Circle and keeps frigid air contained. However, when this storm weakens or shifts position, cold air may be discharged to mid-latitudes anywhere around the globe.
"The cold outbreak with lake-effect snow from the Midwest to the central Appalachians may last a couple of days or perhaps right through the Thanksgiving weekend," according to AccuWeather Meteorologist Evan Duffey.

Major storm may precede rush of polar air in northeastern US prior to Thanksgiving
A disruptive storm packing rain, wind and snow may evolve in the eastern half of the United States as Thanksgiving travel begins to ramp up late this week and into next weekend.
Motorists along major thoroughfares in the East could face slow travel and difficult driving conditions. Airline passengers may have to adjust flight times due to delays and cancellations.
Ripple-effect airline travel delays may result elsewhere across the country.
The storm will be spawned as polar air drops southward across the Midwest and East late this week and into the coming weekend.
“We will have to wait and see the exact storm track, but at least some travel delays can be expected across the Northeast from heavy rain, snow and some rather strong winds,” AccuWeather Long-Range Meteorologist Evan Duffey said.

How has Society Adapted to Hurricanes?
As we faced an intense hurricane season this year, a historical perspective looks at our own adaption to hurricanes, especially in New Orleans, over nearly three centuries, from its foundation in 1718 to the horrors of Katrina in 2005.
It all came as a devastating shock, how could such a disaster have happened in one of the most technologically advanced nations in the world? Digging deeper into this question may unlock the secret on how societies deal with such extreme events and whether they will be able to adapt to future conditions.
Professor Eleonora Rohland, author of the historical perspective, states that lessons may be learned in the aftermath of disasters but have the easy potential to be disrupted by changing political regimes or population migration. Both of which may be no longer willing to adapt.
"The historical long-term perspective reveals that we are at a watershed moment in human history right now: adaptation -- to climate change or increasing/stronger extreme events such as hurricanes -- has turned from a contingent and drawn out historical process into an imperative, a prescriptive policy, almost," said Prof. Rohland. "For current climate change adaptation research, it is worth looking into the historical record to take into account the cultural, societal, and political factors that hampered adaptation in the past in order to be prepared for the future."
