This week has the potential to bring a wave of messy weather across the United States as travelers take to the roads and airports ahead of the Thanksgiving holiday.

The National Weather Service is predicting “messy Thanksgiving trips” across the eastern U.S., with a mix of rain and snow in some areas.

Rain and snow are also expected in the Pacific Northwest, which is still recovering after a major storm killed two people last week.

Temperatures are expected to drop in most of the country.

The East Coast will see the worst of the weather toward the end of the week and closer to the Thanksgiving holiday.

A low-pressure system is expected to bring rain to the East Coast on Thursday.

It could also bring snow to higher elevations and colder states in the Northeast, including Maine and New Hampshire.

The southeast also expects rain and a cold front on Thursday.

The Midwest and Great Lakes region are likely to see heavy lake-effect snow over the weekend, according to the National Weather Service.

Even the western US will not be spared wet weather.

The National Weather Service has issued a winter storm warning for California’s Sierra Nevada Mountains through Wednesday. The worst of the storm will hit on Tuesday.

At higher altitudes, heavy snow is expected with wind gusts of up to 81 km per hour.

Snowy roads and travel delays are likely with “very difficult travel” expected above 5,000 feet, according to the National Weather Service.

Meanwhile, Central California is expecting another atmospheric river event on Tuesday after experiencing a similar event last week.

And in the Pacific Northwest, communities are still recovering afterward last week’s bomb cyclonean intense weather event that occurs when air pressure off the coast drops rapidly.

The storm caused massive flooding and power outages for hundreds of thousands of people.

The affected areas may experience even wetter weather this week.

The National Weather Service is forecasting a low-pressure system that will bring coastal rain to Washington, Oregon and California.
