Dan Zarrow's Forecast

A popup thunderstorm is possible somewhere in New Jersey on Thursday, but don't expect it to cool things down much.

Weather conditions across New Jersey will go downhill during the day Friday, with heavy rain kicking in Friday night and peak wind gusts coming on Saturday.

Friday is a big transition day for New Jersey: From warm to cold, from humid to dry, and from wet to icy.

Over a foot of snow has already accumulated in part of New Jersey, with strong winds making for blizzard, near-whiteout conditions and frigid wind chills.

There is now little doubt that we've got a legitimate winter storm on our hands, as a powerful nor'easter flies by, burying the Jersey Shore in snow.

There's still a good chance that New Jersey's impending nor'easter wiggles closer to or away from the coast, requiring big adjustments in snow totals.

A powerful coastal storm system will fly-by New Jersey from Friday into Saturday, leading to a chance for accumulating snow and gusty winds.

Tuesday will probably be New Jersey's warmest day through the rest of January.

The first 23 days of January had 13 days with temperatures stuck below-normal; New Jersey will add to that total this week.

New Jersey turns wintry again Thursday, with slippery roads, reduced visibility, and the return of arctic air.

An inch or two of snow accumulation could cause slippery roads and minor travel issues across New Jersey during Thursday morning's commute.

The second half of January is "the dead of winter," so it should be no surprise we're talking about cold, windy, and even snowy weather.
