Snow squalls pummel Northeast in wake of winter storm that dumped foot of snow in Pennsylvania, New Jersey

Over a dozen Snow Squall Warnings were issued on Saturday in counties in New York, Pennsylvania and Massachusetts. The warnings were issued as cold air flowed over the Great Lakes, causing sporadic yet intense snow showers in the downwind areas.

LYONS, Pa. – A fast-moving winter storm that was due to bring a few inches of snow to the mid-Atlantic and Northeast Friday night instead packed quite a punch for some in New Jersey and Pennsylvania, who awoke Saturday morning to find more than a foot of snow had fallen overnight.

While the steady snow has since moved out into the Atlantic, the impacts are not finished. Over a dozen Snow Squall Warnings were issued on Saturday in counties in New York, Pennsylvania and Massachusetts. The warnings were issued as cold air flowed over the Great Lakes, causing sporadic yet intense snow showers in the downwind areas.

Snow squalls are like a miniature blizzard with gusty winds that typically last less than an hour. Very high snowfall rates, on the order of 2 inches in 30 minutes, are not uncommon. They are extremely dangerous for travelers as the visibility can drop to near zero, leaving drivers disoriented and unable to see other traffic. Some of the largest multi-vehicle pileups during winter weather have come from sudden snow squalls.


Lake-effect snow is expected to continue through at least Monday, primarily in the eastern Great Lakes region. Drivers are urged to use caution and be prepared for sudden dips in visibility.

Snowfall forecast through Monday, Feb. 19, 2024.

The National Weather Service has issued Lake-Effect Snow Warnings downwind of Lake Ontario in northern New York, including cities like Watertown and Potsdam.

Winter Weather Advisories are also in effect for portions of central and western New York, including Buffalo and Niagara Falls.


Winter weather alerts in effect until Monday, Feb. 19, 2024.

Storm system drops several inches across a dozen states

Outside the snow squalls, the fast-moving clipper system left a blanket of snow across parts of at least a dozen states from Ohio to Massachusetts Friday night and early Saturday.

The highest accumulations were observed when a narrow band of intense snowfall dumped around a foot of snow on eastern Pennsylvania and New Jersey.

The FOX Forecast Center said that heavy snow bands caused snow rates to exceed 1 inch per hour in the region, but some places saw snowfall rates that were mind-boggling. 

One spotter in Hellertown, Pennsylvania, measured over 5 inches of snow in an hour, and over 11 inches in total Saturday morning. Lyons, Pennsylvania, reported exactly 12 inches. 

In New Brunswick, New Jersey, an observer reported that 9.3 inches of snow had fallen as of early Saturday morning.

Outside the heavy snow band, spotters reported 4-6 inches in the area surrounding Pittsburgh, while 5-8 inches of snow piled up in eastern Pennsylvania, extending into other parts of New Jersey.

New York City, which has struggled to see much snow over the past two winters, awoke to a few inches that had fallen across some boroughs

Snowfall in Central Park totaled 2 inches, while John F. Kennedy International Airport recorded 6.1 inches. 

Coney Island was the New York City area snow winner, coming in at just under 10 inches of new snow. 

The storm stayed a bit farther north of the Washington-Baltimore corridor, with just 1-2 inches measured around that region Saturday morning, though there were a few isolated spots of 3-4 inches. Another 3-6 inches fell across the mountains of Virginia and West Virginia.

Snow wanes but winter chill remains 

The snowfall is decreasing as the low-pressure system moves away from the region. However, the wintry impacts will not stop there. 

Winter weather is expected to stay this weekend, bringing high temperatures in the 20s and 30s. The wind chill is expected to drop into the single digits to near zero at night. 

Starting Monday, the region will be on a gradual warming trend through the week before the next chance of wintry weather next weekend.

Snowfall causes problems throughout the Midwest, including deadly crash

The fast-moving storm system dropped a quick 2-5 inches of snowfall along the Interstate 74 corridor in the Midwest on Friday morning.

The frozen precipitation was the first flakes cities such as St. Louis and Indianapolis have seen within the past month, according to the FOX Forecast Center.

A pileup crash on Interstate 70 outside of St. Louis shut down parts of the interstate for several hours, and photos from the scene showed at least one jackknifed semi truck and several stranded vehicles. Troopers have not said how many people are believed to have been injured or how many cars were involved in the crash near Warrenton, Missouri, but the crash certainly made for a rough commute.


Outside of Lake Ozark, Missouri, a deadly crash was reported by troopers in Morgan County. The Missouri State Highway Patrol said a driver lost control during slick conditions on Friday morning.

Outside of the Plains, the highest accumulations were in central Illinois and Ohio, where snowfall topped more than a half-foot in several communities.

As of Friday evening, Springfield, Illinois, reported a snowfall total of 6.5 inches, while Marysville, Ohio, had reached 6 inches.
