— STATE COLLEGE — The meteorologists at Accuweather today increased their snowfall forecast to around 12 inches of snow late Sunday night into Monday across the Central Susquehanna Valley.
The snow will expand from the northern Rockies and central Plains to portions of the Midwest this weekend, reaching the Northeast early next week, said Alex Sosnowski, an expert senior meteorologist at Accuweather.
The adverse winter conditions will develop Friday into Saturday over the Plains and is forecast to shift slowly eastward Sunday and Monday.
Snowfall from the cross-country storm will exceed 1,500 miles on its journey. There is the potential for more than 6 inches of snow to fall along a 1,300-mile stretch from Topeka, Kan., to Kansas City, Mo.; Peoria, Ill.; Indianapolis; Columbus, Ohio; Pittsburgh; Philadelphia; New York City; Hartford, Conn.; Providence, R.I.; and Boston.
People traveling by road or airways should expect major long-lasting delays as this area of snow expands eastward and crawls along.
Major airport hubs from Kansas City, Mo., Chicago, St. Louis, Indianapolis, Detroit, Cincinnati, Pittsburgh, Washington, D.C., Philadelphia, New York City and Boston may all be directly affected by the storm with the potential for thousands of delays and/or cancelations. Ripple-effect flight delays and cancelations are likely to reach nationwide.
However, it is during the last part of the storm, when the heaviest and longest-lasting snow is likely to occur centered farther south. The heaviest snow is projected to be Sunday to Sunday night over the northern Ohio Valley states to part of the central Appalachians and Sunday night and Monday in the coastal Northeast.
According to AccuWeather Chief Meteorologist Elliot Abrams, “The challenge with this storm is figuring out where the north-south boundary between rain and snow will set up and migrate to as the storm progresses slowly eastward.”
“In a narrow swath, all or part of the storm will deliver snow that may be difficult to shovel and plow, due to its accumulation and weight,” Abrams said.
A tremendous temperature contrast will set up from north to south with the storm. A distance of 100 miles could bring temperatures ranging from the 60s and 70s to the 20s and 30s and the difference between rain, ice and snow, Abrams said.
