Quick-moving storm system to produce round of thunderstorms over Northeast on Sunday

While Saturday looked wintry to some in the Northeast, a fast-moving storm system moving out of the Great Lakes has a chance to produce showers and thunderstorms on Sunday.

The FOX Forecast Center expects thunderstorms to develop late morning and afternoon as they work northwest to southeast across the region.

The Storm Prediction Center highlighted communities from the eastern Ohio Valley to western Massachusetts as being at risk for strong to severe storms.

Communities such as State College and Scranton, Pennsylvania, are included in NOAA’s Level 3 of 5 Severe Storm Threat Zone.

Destructive winds are expected to be the main danger, but a brief tornado and hail are also possible in the strongest storms.

Around 34 million people are in the “possible” threat zone on Sunday, including 2 million in the “very likely” region.

Fortunately for the I-95 corridor, the threat of damaging thunderstorms is expected to diminish significantly after sunset as storms run out of energy.

Cities like Philadelphia, New York, and Boston are on the edge of or just outside the “possible” severe weather threat zone.

Depending on where the first showers and thunderstorms develop, additional precipitation could fall across the eastern Ohio River Valley.

Although significant flash flooding is not expected, dozens of water gauges along the Ohio River and its tributaries are in flood stage and any additional rain will worsen water levels.
