Discussion

A major coastal storm will impact the region today as it slowly moves up the Mid-Atlantic coastline while intensifying. As it reaches the latitude of Long Island or southern New England later tonight, it will run into an “atmospheric road block” forcing the storm to stall out or even loop around ensuring a long-duration event in the Northeast US and more precipitation around here from tonight into Thursday. The bulk of the precipitation today in the immediate Philly metro region should be in the form of plain rain, heavy at times, but as colder air wraps into the system tonight, there can be a changeover to steady snow or snow showers and the threat for more snow will continue on Wednesday into Thursday. Slick spots are possible late tonight into Wednesday during any snow shower activity and some snow accumulations are still on the table. Coastal sections of New Jersey could see wind gusts past 50 mph during the height of this major nor’easter later today and early tonight and flooding will be an additional concern in those areas. The best chance for significant snowfall accumulations over the next 24 hours or so will extend from the mountains of upstate Pennsylvania to interior New England where more than a foot can easily fall by Thursday.
