Wintry weather could cause hazardous travel conditions for those planning to hit the road this Thanksgiving, according to Townsquare Meteorologist Dan Zarrow.

Zarrow says there is a possibility for snow accumulations as the holiday approaches.

"There is still a lot of uncertainty with this system," Zarrow said Sunday. "If it weren't one of the biggest travel weeks of the year, I (and other forecasters you've seen post things online) would not give this any real substance until tomorrow. At this point, I'm willing to admit there is a chance for 3-6 inches of snow accumulation."

The National Weather Service in Mt. Holly is calling for a 70 percent chance of rain and snow before 9 a.m. on Wednesday, then rain with a high temperature of 42 degrees. For Wednesday night, the NWS predicts a 50 percent chance of rain and snow, followed by clouds and temperatures around 30 degrees.

"No matter what kind of precipitation this storm system spits out and exactly where, there will be big-time travel headaches," Zarrow said.

AAA is predicting that approximately 1.2 million New Jerseyans will travel 50 miles or more from home during the Thanksgiving holiday weekend, up 4.1 percent from 2013. In fact, Thanksgiving holiday travel volume is expected to reach the highest level since 2007.

But even before any potential snowfall, New Jerseyans will have rain to contend with earlier in the week.

"We're going to see some pretty solid rainfall tonight and early tomorrow morning," according to the meteorologist.
