Cold, blustery and snowy weather to strike northeastern US on Thursday

While a major snowstorm is not in the cards, rounds of snow showers and a fresh blast of wintry air could lead to travel disruptions across the Great Lakes and Northeast into Thursday night.

Compared to midweek, snow showers are expected to be more widespread on Thursday, when fresh cold air will arrive.

Static NE Thursday


Winds are expected to blow out of the northwest, allowing frigid arctic air to spill across the Great Lakes and into the Northeast.

Blustery conditions will cause AccuWeather RealFeel® temperatures to plummet.

The flow of cold air will promote the formation of lake-effect snow, according to AccuWeather Meteorologist Brett Edwards.

"The worst of the snow will be expected late Thursday afternoon and Thursday night as very cold air aloft swings through the area," he said.

"The worst of the snow is expected to occur downwind of Lake Ontario with 6-12 inches of snowfall expected."

These heavy snow squalls will quickly coat roads and bring visibility to near zero, presenting dangerous conditions for anyone on the road.

Anybody out and about at the end of the week in these areas should take care to slow down significantly during periods of heavy snow, or avoid driving at all.

"A weak disturbance will pass through southern Canada and the Northeast through Thursday evening," Edwards said.

This will produce a quick-hitting batch of snow showers that will overspread a much larger swath of the region outside of those areas impacted by lake-effect snow.

Similarly poor road conditions will be possible in these areas as well. Anyone traveling on Interstate 75, I-96, I-94, I-90, I-70, I-80, I-99, or I-81, among others, should pad their travel plans with plenty of extra time. Dangerous pileups can occur when drivers are moving at highway speeds in slick, low-visibility conditions.

"If people can adjust their travel time or take a route that does not involve high-speed driving on a major interstate in the risk area, it may not only save them major delays, but also the danger of being involved in a chain-reaction accident," according to AccuWeather Senior Meteorologist Alex Sosnowski.

Airline delays are possible as well in St. Louis, Detroit, Indianapolis, Pittsburgh and Toronto.

The colder air mass will be noticeable by Friday, when high temperatures are expected to be 5-10 F lower compared to Thursday.
