'Rollercoaster' Weather Week Ahead: See Eastern PA Thanksgiving Travel Forecast

Multiple days of rain along with bouts of potential fog could create bedlam on the roads in Pennsylvania during the busiest travel days of the entire year, according to forecasters.

Turkey week turmoil is likely to begin on Tuesday afternoon, with a chance of some light rain in the afternoon, the National Weather Service said. Rain is likely to increase Tuesday night, with up to a quarter of an inch overnight, and could continue throughout the day Wednesday and through the evening hours Wednesday night.

The storms are not expected to be severe. The danger comes from the timing and the sheer volume of traffic expected on the roads. Rain is likely to fall during peak travel hours, during which Accuweather noted that "rain-slicked highways and fog" are possible and even likely in some areas.

"As the volume of highway and airline traffic increases, the likelihood of delays will mount," Accuweather added. "Blowing spray on the highways can increase the risk of accidents and temporary road closures. Poor visibility at airports may force flights to operate under Instrument Flight Rules (IFR) and may require greater spacing between departing and arriving aircraft."

The National Weather Service's Mt. Holly, New Jersey branch similarly described the midweek as a "roller coaster" after a tranquil Monday.

Accuweather says airline delays are most likely along the east coast on Tuesday night into Wednesday due to the fog. The number and extent of delays later in the day will depend how quickly the fog clears.

AAA said they expect a busier Thanksgiving on the roads and in the air than a year ago. Some 81.8 million people are expected to travel at least 50 miles from Tuesday, Nov. 25 through Monday, Dec. 1. That's an increase of some 1.6 million over last year.

Roughly 73 million of those travelers will be on the roads.

Thanksgiving Day itself is expected to be cool and dry, with a high of 44 and no rain currently in the forecast. Clear and chilly conditions with persist through the weekend, with lows in the high 20s and low 30s, but no precipitation expected, forecasters said.
