How much snow is falling in your state this weekend? See the latest forecast

According to Weather.com, a major, widespread winter storm will bring heavy snow across much of the South, Midwest and Northeast Friday, January 23 through Monday, January 26, affecting tens of millions of people from New Mexico to New England.

“It’s not hyperbole to call this storm a monster,” Washington Post meteorologist Ben Knoll said on Jan. 21. At its peak on Sunday (Jan. 25), 55 percent of people in the United States are forecast to experience snow, sleet or freezing rain simultaneously. More than half of the population said.

According to AccuWeather, widespread travel disruptions are possible across the country this weekend. “Ice and snow-covered roads could force highway closures for hours,” AccuWeather Chief Meteorologist Jonathan Porter told USA TODAY in an e-mail.

“Key east-to-west interstates that are critical for travel, commerce, and delivery, including Interstates 20, 30, and 40, may experience simultaneous closures, compounding challenges for travelers and supply chains.”

As for snowfall totals, 6-12 inches of heavy snow is possible in the heart of the Plains, with more than 2 feet possible in parts of the Appalachians, AccuWeather said in an online forecast.

How much snow falls in the Mid-Atlantic and Northeast will depend on the storm’s exact track, but significant and plowable amounts — possibly up to a foot or more — are possible.

Southern Plains and Mid-South

According to AccuWeather, heavy snowfall of up to a foot is forecast for central Oklahoma on Friday, January 23rd and Saturday, January 24th. Lesser amounts, possibly 3-6 inches, will fall in Arkansas, Kansas, Missouri, New Mexico and Texas.

In Arkansas, the central and northern parts of the state have a 30-50% chance of more than 6 inches of snow, the weather service said. In Tennessee, there is a high chance for at least 6 inches of snow north of Interstate 40, the weather service said.

Snow, sleet and ice could dip farther south in Texas, Louisiana and Mississippi, while it picks up in parts of Kentucky, Tennessee, West Virginia, Virginia and the Carolinas, Weather.com meteorologist Jonathan Erdman said in an online forecast.

Southeast and East Coast

Winter showers will end in Texas, Oklahoma and the lower Mississippi Valley by midday on Sunday, Jan. 25, but will continue from the Ohio Valley into Virginia’s Piedmont and the Carolinas, according to Weather.com. Heavy snow is also possible in parts of the Ohio Valley.

The winter storm “is expected to bring widespread heavy snow to the Mid-Atlantic and Northeast this weekend,” according to Weather.com.

A map posted by Weather.com showed totals of 2-3 feet of snow in southern Virginia, with 1-2 feet spread across a wide swath of the Mid-Atlantic.

“The latest model trends show high snow totals moving north into Washington, Baltimore and Philadelphia. The heaviest snow is expected to fall Saturday night, Jan. 24, through Sunday, Jan. 25, making travel nearly impossible. Snow could last into New England on Monday, Jan. 26.”

Forecast uncertainty

According to the National Weather Service, “Confidence for a major storm is high, but not in specifics for the storm’s track, timing and rainfall amounts. Start preparing now for an effective and long-lasting winter storm and keep up-to-date with the forecast.”
