A blockbuster snowstorm with blizzard conditions could bring travel to a standstill across parts of the Northeast late Sunday into Monday, just days after another major storm pummeled the area.

And a separate storm system will drop temperatures 55 degrees in Texas from Saturday to Monday, threatening snow, ice and rain from Amarillo to Lubbock, AccuWeather said.

The most snow is expected in coastal New England, along with the maritime provinces of Canada, which could get 1 to 2 feet, according to Alex Sosnowski, an AccuWeather senior meteorologist.

The storm will develop into a powerful nor'easter with blizzard conditions expected for parts of Maine as winds intensify, the National Weather Service said. Winter storm warnings were in effect Sunday from upstate New York to northern Maine, where snowfall amounts of 8 to 16 inches were likely with locally higher amounts, the weather service said.

High wind warnings were also in effect along the Appalachians from North Carolina to West Virginia and across portions of Maryland and New Jersey.

“It is a dangerous storm because of high winds, low visibility and heavy snow,” Lenore Correia, a weather service meteorologist in Taunton, Mass., told The Associated Press. “It’s a big snowstorm, but nothing we haven’t seen before either.”

The Boston public school system announced it would be closed Monday because of heavy snow. New Hampshire Gov. Chris Sununu urged motorists in a tweet to slow down and avoid travel if possible.

Connecticut State Police tweeted that they had responded to 46 accidents, including three with injuries, from 8 a.m. to 1:30 p.m. They also assisted 57 drivers and responded to 356 calls for service.

The Federal Aviation Administration was investigating why a Gulfstream G280 slid off the end of a runway at Hanscom Field in Bedford, Mass., after aborting a takeoff at 2:30 p.m. Sunday. Ryan Schulteis of Channel 7 news in Boston tweeted that five people were aboard the flight for Teterboro, N.J., and all were evacuated.

Nearly 800 flights within, arriving or departing the U.S. were canceled Sunday, according to FlightAware.com, an online tracking service. Boston Logan scrapped 262 flights, Toronto canceled 230 flights, and Newark Liberty 125 by 3 p.m., according to FlightAware.

The storm last week, which blanketed New England with up to 19 inches of snow, canceled more than 4,300 flights from Wednesday through Friday, according to FlightAware. The cancellations included nearly 70% of the schedule Thursday at Boston and New York LaGuardia airports, and about half the day’s flights at Newark and New York John F. Kennedy airports.

After a mix of rain and snow made roads slippery Sunday, cold air rushing in overnight will create blizzard conditions with 50-mph winds from Portsmouth, N.H., to Bangor, Maine.

“The weight of the snow, combined with fierce, howling winds will be more than enough to bring down tree limbs and power lines,” said Kyle Elliottt, an AccuWeather meteorologist.

In the West, a low-pressure system moving across northern Mexico will bring rain and thunderstorms across the lower elevations of Southwest states in the Four Corners region and snow in the southern Rockies, according to the National Weather Service.

Rain will spread into Oklahoma and Texas by Monday; 1 to 3 inches of heavy rain is likely across west-central Texas.

In Texas, cool air will sweep away July-like heat that broke records on Friday and Saturday. Amarillo's expected high of 35 on Monday could be 55 degrees lower than on Saturday, according to AccuWeather. The temperature in Dallas could drop 30 degrees from the upper 80s on Saturday to lower 50s on Tuesday, AccuWeather said.

The wintry mix of snow and ice will move eastward Monday from New Mexico into the Texas Panhandle.

“As hard as it is to believe, there will be some snow and wintry mix with this storm just days after areas reached or exceeded 90,” said Dan Pydynowski, AccuWeather senior meteorologist.
