Jan 29: Snow Storm Detected!

Model guidance is in pretty strong agreement that a snow storm will impact New Jersey in the Sunday evening-Monday evening time period. With this system an overall weak low pressure disturbance will pass to the south of NJ…somewhere near the Virginia/North Carolina border. The northern side of the low’s precipitation shield should bring significant snowfall throughout the region. Let’s look at the supporting guidance, specifically 850 temp, pressure, and precip maps:

18Z GFS (1AM-7AM Monday):

12Z Canadian GEM (7AM-1PM Monday):

The 12Z Euro is almost a carbon copy of the 18Z GFS. The Canadian is a little slower and further south but still brings significant snowfall to at lease CNJ and SNJ. This is pretty decent model guidance agreement so at this point we should prepare for widespread significant snowfall accumulations.

In English: Snow should begin on Sunday evening sometime during or just after the big game. It should snow overnight and well into Monday. I’ll release a first call snow map tomorrow night but as of right now, widespread 4-8/6-10 inch snowfall accumulations are likely when everything clears out by Monday evening. Current model guidance favors SNJ over NNJ but let’s see how that evolves over the weekend. Be safe! JC
