A blast of cold air behind a potent storm system will return snowy conditions to parts of the Northeast to start the weekend.
The storm that brought locally heavy rainfall to parts of the Northeast on Friday will continue to push through the region on Saturday.
By 4 p.m. EST, Portland International Jetport had received a record-breaking 3.37 inches of rainfall, shattering the previous record daily rainfall of 1.74 inches from 1917, according to the National Weather Service.
The deluge of rain brought flooding to the streets of Portland, Maine, catching a few cars that tried to pass through.
While the heavy rain threat will shift north into New England, wintry weather will return to southern parts of the Northeast.
The above radar image shows rain in much of the Ohio Valley, with some precipitation changing over to snow late Saturday morning.
As the storm tracks north, it will pull colder air south into the region, causing rain to gradually change over to snow.
Rain is expected to begin changing over to snow throughout Saturday morning in Ohio, then into far western Pennsylvania and New York by late Saturday morning.
Early Saturday afternoon, snow will spread east into central Pennsylvania before expanding across the northern tier of Pennsylvania and the Finger Lakes region in New York.
The storm will continue to push north Saturday night. Snow across much of the region will gradually taper off, but it will continue to fall across the Adirondack Mountains, as well as northern Vermont and New Hampshire, mainly in the higher elevations.
Snow showers are also expected to linger in the mountains of West Virginia and south-central Pennsylvania.
Meanwhile, northwesterly winds will continue to usher in colder air across the Great Lakes, triggering lake-effect snow.
Snowfall totals of about 1-3 inches are expected from the Appalachian Mountains across much of New York.
Totals in the 3- to 6-inch range are forecast in the higher elevations of West Virginia and Pennsylvania, as well as where lake-effect bands set up.
Snowfall can approach a foot due to snow squalls off Lake Erie and an AccuWeather Local StormMax™ of 15 inches is possible in the heaviest bands.
The Interstate-95 corridor looks to escape this fresh round of snowfall as a pocket of dry air is expected to keep the region largely precipitation-free Saturday afternoon and Saturday night.
Travel conditions can become slick across these areas despite the lack of snow as plummeting temperatures can lead to icy spots on wet roads and sidewalks.
Any lingering snow in the Northeast will gradually dissipate into Sunday evening, but the break in wintry weather is not expected to last long. Snow and ice are forecast to arrive across the Ohio Valley, West Virginia and into southwestern Pennsylvania late Sunday night as a far-reaching storm approaches the region.
