We’re entering the last full work week before Christmas, and if you’re getting an early start on holiday travel, be prepared for delays on the roads and in the air as a series of squalls move across parts of the US

The FOX Forecast Center said cities in the eastern half of the country should prepare for periods of heavy rain and possibly some wintry weather, which could slow holiday traffic.

The new work week began with a rapid outbreak of winter weather that pushed into the Mid-Atlantic and Northeast, capping off the weekend and Monday.

Meanwhile, the system has begun pushing offshore activity and all winter weather warnings were allowed to expire, but commutes were slow for millions of people on Monday morning and schools were forced to delay opening until closing due to dangerous travel conditions.

Behind this system, a stronger low pressure system is expected to develop over the Tennessee Valley and bring several inches of rain to portions of the lower Mississippi, Tennessee and Ohio valleys by midweek.

The system will then move into the mid-Atlantic, spreading significant amounts of rain along its path. The FOX Forecast Center said on Wednesday it even appears that the greatest impacts will spread to this region as the system slides off the coast and strengthens.

When this happens, colder air will move back into parts of New England and the Northeast, potentially leading to more snow in areas hit hard by snow in recent weeks.

After that, one question remains.

Do the new federal airline reimbursement rules cover weather-related delays?

The FOX Forecast Center said there are indications that some winter weather could impact the Interstate 95 corridor by the end of the week, but details are still uncertain. While computer forecast models suggest the rainfall will spread across the East Coast, details will be released in the coming days.
