Back-to-back winter storms for NJ: County-by-county breakdown

UPDATE... This article is outdated...

For the latest storm forecast information, please refer to my newest weather blog post.

The Bottom Line

Bring on the snow! Our next burst of wintry weather is set to arrive late-day Tuesday. And this time around it is all snow and a "South Jersey Special," with over a half-foot of accumulation possible along the southern edge of the state. To the north, a big goose egg, with little to no snowfall expected for North Jersey.

My final forecast call has nudged snowfall totals down a little bit, given a slightly later arrival of first flakes and a slight southern jog of snow bands in the latest model data. It is still going to get snowy, sloppy, and slippery across most of New Jersey during the brunt of the storm Tuesday night.

A Winter Storm Warning has been issued for the three southernmost counties in New Jersey, from late Tuesday afternoon through Wednesday morning. A Winter Weather Advisory covers an additional seven counties, as far north as Mercer and Monmouth counties. That is your geography and timing of the most treacherous travel conditions.

Of course, Tuesday evening's storm is not the only game in town. On its heels, there is another potent storm system set to move into New Jersey starting Wednesday evening. While it will start with a quick burst of snow, warming temperatures will eventually force a transition to plain rain by Thursday morning. Some combination of light snow and ice accumulations are possible in North Jersey. But for most of New Jersey, this one will just be slushy and wet.

Finally, this weekend turns inclement too. Time frame for storm #3 is Saturday afternoon through the day Sunday. According to the latest guidance, it will be another rainmaker for most of New Jersey. And a good soaker at that, with over an inch of total rainfall. However, some accumulating snow is a possibility for northwestern New Jersey. And there is a chance that freezing line drifts southeast through more of the state — in that case, we might have to ring alarm bells for more serious, more wintry weather. (We will fill in more of those details in the coming days.)

For the rest of this morning's weather blog post, I want to give you an easy-to-skim county-by-county rundown of Storm #1 (Tuesday night to Wednesday) and Storm #2 (Wednesday night to Thursday). For each, I give a sense of the overall impact level, the timing, and potential accumulations. All the numbers here are approximations and estimations, so blur your eyes a little bit and keep expectations in check. Hopefully this information helps you plan your day(s) adequately and stay safe.
