A ‘potentially significant’ storm could hit the east coast during the busy Thanksgiving travel week

A significant storm has the potential to disrupt travel plans from the Midwest to the Northeast at one of the busiest times of the year to travel. We’re talking about disruptions in major airline hubs like Chicago and New York early next week.

The storm system could begin to develop on Sunday in the Midwest and strengthen daily. As it approaches the east coast on Tuesday, a secondary system could develop along the coast, exacerbating the disruptive weather conditions in places like New York.

“It’s too early to resolve detailed effects from low pressures that may be near the east coast next Tuesday, but significant rain / snow and strong winds may be possible,” the WPC said.

“Even though we’re still almost a week out and the forecasts may change, it looks like a plane, train and car storm,” said CNN meteorologist Chad Myers.

Here’s a look at where some of the worst travel disruptions could occur, based on computer forecasting models.

The only good news: Computer forecasting models are not always accurate. Especially a week in advance.

There is a lot of uncertainty in the forecast Sunday night and beyond, the National Weather Service in New York said Tuesday morning, so there is low confidence in the forecast.

On Tuesday afternoon, the forecast models will have been run again. The output Tuesday night, Wednesday or Thursday may be different than it was earlier this morning.

It is in the consistency and trends from one model run to the next that meteorologists will follow closely. That’s what will build their confidence in next week’s potential storm.

“Even if the storm disappears by Wednesday, airlines can still handle significant past cancellations with planes and crew members in the wrong place,” Myers said. “This storm has really bad timing.”
