Discussion
Low pressure will intensify off the Mid-Atlantic coastline today and push very slowly to the north as it encounters a blocking pattern in the atmosphere. The brunt of this winter storm will take place from later today into tonight as heavier rounds of precipitation work their way across southeastern New York and New Jersey and the winds will pick up in intensity as well. Any mixed precipitation this morning should change back to all snow by mid-morning as colder air wraps around the intensifying storm off the Mid-Atlantic coastline and significant additional accumulations are likely. Given very strong dynamics in the upper atmosphere, there is the potential for “mesoscale” or small-scale banding later today and tonight containing brief outbursts of very heavy snow and possible rumbles of thunder. Total snow accumulations from this storm by later tomorrow can surpass a foot and a half in the NYC metro region.
