[2/7/17] Winter Storm Niko will likely bring heavy snow for much of the Interstate 95 corridor in the Northeast Wednesday night through Thursday. Some areas could pick up a half-foot or more of snow in a short amount of time.
The snow will make for a tough commute Thursday in Boston and New York City, and potentially Philadelphia, Baltimore and Washington D.C as well.
Winter storm watches have now been posted by the National Weather Service for parts of southern New England southward into the New York City metro area and westward into south-central Pennsylvania.
The setup for this snow event features a pattern seen frequently in past winters, but not so much this winter.
A sharp southward plunge of the polar jet stream in the East will spawn an area of low pressure off the Eastern seaboard by Thursday.
With some cold air in place behind departing Winter Storm Maya, Niko should wrap moisture into sufficient cold air to wring out snow, heavy at times, near the I-95 corridor.
As virtually always is the case, there are uncertainties on the exact track and forward speed Niko. The latest forecast guidance is suggesting a track favorable for widespread accumulating snow, with the heaviest amounts from eastern Pennsylvania and the New York City Tri-State area into southern New England.
For now, this doesn’t appear to be a blockbuster Northeast snowstorm, but it will likely disrupt travel on Thursday.
Here’s the timeline and how much snow could fall.
