Gusty winds are ushering in some of the coldest air yet this season across the northeastern United States, but how long will these conditions last?

The lower temperatures are being funneled into the region behind a 'meteorological bomb' that brought flooding rainfall, damaging winds and pounding seas at midweek.

While the heaviest rainfall will exit New England and move into the Canadian Maritimes by Thursday afternoon, rain and high-elevation snow showers are forecast to linger behind the storm.

Crews working to restore power or cleaning up debris left behind by the storm will face chilly, blustery weather into Friday.

Wind gusts of 35-55 mph will be common across the region on Thursday, with an AccuWeather Local StormMax™ of 70 mph possible over the high terrain and along the coast. Tree damage and power outages will remain a concern amid the gusty weather.

The winds will also create low AccuWeather RealFeel® Temperatures, in the 30s across the interior and 40s closer to the coast, despite actual temperatures being 10-15 degrees Fahrenheit higher.

Winds will lighten up from west to east across the region on Friday as an area of high pressure moves in. This high will also promote a sunnier sky when compared to Thursday.

Friday's highs will be 5-10 degrees below normal over the interior, generally in the 40s and 50s. However, the increase in sunshine and lightening winds will help it feel less harsh than Thursday.

The winds could help to boost fly balls out of Yankee Stadium for Games 4 and 5 of the American League Championship Series (ALCS) on Thursday evening.

Those heading to Game 5 of the ALCS in the Big Apple on Friday evening can expect temperatures in the lower to middle 50s throughout the game with AccuWeather RealFeel® Temperatures dipping to the upper 40s.

The clear skies and light winds will allow temperatures to plummet on Friday night.

A frost can occur in locations that have avoided a growing season ending event in parts of the mid-Atlantic and central New England, according to AccuWeather Senior Meteorologist Alex Sosnowski.

"A few locations may equal or dip slightly lower than their lowest point so far this season in terms of actual temperature by Saturday morning," Sosnowski said. "That mark is 34 F in Pittsburgh, 42 in Boston, 45 in New York City, 46 in Philadelphia and 49 in Washington, D.C."

Those heading out on Saturday morning to run errands, walk the dog or tailgate ahead of college football games will want to dress in layers. While the morning hours will start out chilly, temperatures will rebound nicely during the afternoon amid dry conditions.

"Temperatures are forecast to rebound for several days this weekend and into next week before much colder air sweeps in prior to the end of October," Sosnowski said.

Saturday's highs will be in the 50s and 60s, with daytime temperatures likely to climb a few degrees more on Sunday.

While dry weather is likely to hang on for much of the region over the weekend, which is great news for those leaf peeping or heading to fall festivals, there can be a brief period of rain that sweeps through the lower mid-Atlantic from Saturday night into Sunday.

This wet weather will be associated with a system that AccuWeather meteorologists are monitoring for potential tropical development in the Gulf of Mexico before it moves ashore in the Southeast.
