Maps show where the next blast of Arctic air and a potential winter storm are expected to travel this weekend, according to the latest forecast models.

On the heels of Winter Storm Fern, a strong storm will form off the East Coast this weekend that will bring snow, wind and coastal flooding. Here is our latest forecast.

A life-threatening bomb cyclone is barreling towards the Northeast — threatening to slam New York City with even more snow and a record-breaking stretch of subfreezing temperatures. The powerful storm is expected to swirl into the city Saturday night or early Sunday, dumping up to 3 inches of snow in the already-buried Big Apple .

Snow, wind, coastal flooding, and even blizzard conditions could be possible with the storm expected to impact Massachusetts on Sunday — but location is everything as this forecast comes together.

STATEN ISLAND, N.Y. — This weekend’s nor’easter is forecast to bring 1 to 3 inches of snow and gusts of up to 40 mph to New York City, according to AccuWeather Senior Meteorologist Tom Kines. The storm is also classified as a bomb cyclone, as it is expected to rapidly intensify.

Six states are under Winter Storm Watches as a powerful nor'easter has its sights set on the East Coast, with the potential to 'bomb' out and slam the Carolinas and Virginia.

That uncertainty is not unusual at this early stage. Forecasters rely on a blend of weather models — computer simulations used to predict future conditions — and they are more confident in a forecast when most of those models are consistent with one another. The closer the storm is, the more confident forecasters become.
