On Wednesday, January 21, and heading into Thursday, January 22, the National Weather Service (NWS) announced new winter storm warnings for areas across the U.S. facing severe weather, even in states not used to the cold.

A winter storm watch has been issued for most of Pennsylvania, including the Harrisburg region, from Saturday night through Monday afternoon. Significant snow accumulation is expected. Forecasts show the potential for widespread heavy snow, with some areas possibly receiving more than a foot.

NYC, as well as parts of NJ, could see over 10 inches of snow this weekend as a winter storm threatens to bring heavy snowfall and colder air to parts of the Northeast, according to forecasters.

The Susquehanna Valley could see more than 12 inches of snow this weekend. The WGAL News 8 Storm Team is tracking the latest models and totals.

A pair of forecast models continue to disagree about the chances and types of winter weather expected for portions of the Lowcountry this weekend.

The chances of heavy snowfall in the region this weekend are increasing. The Pittsburgh office of the National Weather Service in a social media post said the notion that the region could see no snow this weekend “has been completely thrown out.

On Thursday at 3:36 p.m. EST a winter storm warning was issued by the National Weather Service in effect until Friday at 1 p.m. EST for Emmet, Cheboygan, Antrim, Otsego and Charlevoix counties.

The National Weather Service issues a litany of notices before and during inclement weather events. They can be important signals on how to respond.
