We’re currently tracking the first widespread snowstorm of the 2019-2020 winter season across the Northeast, and it couldn’t come at a less ideal time of the year with one of the biggest travel weekends upon us.

A large storm system currently spreading heavy snow and severe weather across the center of the country will move east overnight and into tomorrow morning. Enough initial cold air will be in place over the Northeast that rain will become freezing rain and snow on the outer fringe of precipitation.

As the sun rises on Sunday morning, moderate freezing rain will likely be falling across the entire state of Pennsylvania along with extreme western New York. By the mid-morning and early afternoon hours, steady snow will breakout from Syracuse to Albany to southern New England. By this time the quick period of freezing rain, sleet and snow across I-95 will become a cold rain. Interior sections of Pennsylvania will hold onto frozen precipitation into the late afternoon and early evening hours before largely tapering off. Southern New England will become the main focus for freezing rain, sleet, and snow into the evening and nighttime hours of Sunday, while light to moderate snow makes it ways into New England.

This sloppy mess of a storm across the Northeast will be possible thanks to our main storm system transferring low pressure south of southern New England, keeping colder air in place. This is known in the meteorology world as a Miller-B storm system, where a new area of low pressure redevelops offshore the Northeast coastline.

This transfer will be rather slow, and give time for colder air from the north to work its way further south into the coastal storm system. As moderate snow continues overnight Sunday and into early Monday morning across New England and Upstate New York, moisture will likely redevelop on the northwestern flank of the storm. This will lead to additional snowfall across parts of Pennsylvania, New Jersey, The Hudson Valley, and southern New England.

During the day on Monday and into the later hours, our storm will not have moved very much from 24 hours prior. Short range models are even hinting at an inverted-trough-like feature from Albany down to parts of New Jersey and even into the NYC metro region. A couple additional inches of snowfall can be expected from this newly formed feature.

Our storm finally moves out on Tuesday, with gusty winds, colder temperatures, and scattered snow showers across the region. The middle of the week looks quieter. More updates to come from our team tomorrow.
