Potential blizzard brewing for Thanksgiving? Here’s what forecasters are predicting.

There is no need to panic. There is no need to worry about weather disturbances Macy’s Thanksgiving Day Parade.

Forecasters say it’s too early to get a good handle on one potential storm system that could bring some snow or rain to the eastern United States on Thanksgiving Day.

But some meteorologists are laying out different scenarios for what could develop next week – one of the busiest travel weeks of the year.

Forecasters from AccuWeather says nothing is locked in at this time, but they believe there is some potential for accumulating snow in parts of the Ohio Valley and Northeast region of the United States on Thanksgiving and Black Friday, which “could result in widespread disruption for travel and holiday celebrations.

AccuWeather says its forecasters are looking at two different scenarios — one that would be more snowy and another that would be more rainy.

“The first scenario involves a slow-moving storm, meaning potentially extended impacts from the Tennessee and Ohio Valleys through the Northeast,” AccuWeather said in a storm report on its website Friday.

“The second scenario sends the same storm farther south and off the Carolina coast through Thanksgiving,” the private forecasting firm noted. “This would be a less intense storm with rounds of rain and even some snow that could spread from the Tennessee Valley eastward to the East Coast.”

Other Thanksgiving Predictions

The National Weather Service main forecast office in New Jersey takes a very cautious approach to the Thanksgiving forecast because it’s very early and there are a lot of moving parts involved.

“As we turn our attention toward the end of next week, most of our available model guidance suggests a low pressure system will develop and affect the East Coast around Thanksgiving Day into that night,” the weather service said.

“However, as this is still several days out, there is plenty of uncertainty regarding the system’s strength, track and overall development including timing,” the agency said.

The weather service said the storm’s track will be a key factor in whether the system will bring rain, snow or mixed precipitation to the New Jersey and Philadelphia metro region. Based on expected air temperatures at this time, it may not be cold enough to support a major snowstorm.

The weather service regional office in New Yorkwhich covers New York City and five counties in northeastern New Jersey, says it is far too early to make reasonable predictions about next week’s storm system. And even the major computer control models are far from agreeing on the storm’s timing, strength and impact areas.

Some early computer guidance suggests the center of the storm system could end up moving anywhere from the Gulf Coast to eastern Pennsylvania, the weather service noted.

So far, the weather service is predicting partly sunny skies in New York City on Thanksgiving Day, with a high near 45 degrees and a 40 percent chance of showers. The big Thanksgiving Day parade starts at 8:30 a.m. Thursday in Manhattan.
