Bitter cold lingers all week with highs that struggle to reach 20 degrees and overnight lows that will stay int he single digits. The wind chills are abrasive and dangerous as they can be as low as 10 degrees below zero. Aside from the temperatures, the sky conditions will feature small breaks of sun with several clouds.
The lack of sun and cold temperatures prevents the snow from melting or subliminating, thus freezing solid and becoming very difficult to impossible to remove. If you haven't cleaned up by now, it may not be easy or even possible any longer.
There is a chance for a nor'easter to form off of the east coast this weekend, which threatens New Jersey with possible snow on Sunday. The proximity of the track of this particular nor'easter will determine its impacts. The type of nor'easter this could bring near blizzard-like conditions if it tracks in the "right" place. For now, nothing is guaranteed or set in stone and is simply just something to watch. The likely scenarios are pointing toward a "hit" or "miss" scenario.
