Weather is a major factor for the nearly 43 million Americans heading out today and tomorrow for their Thanksgiving travel. AAA predicts that 39 million of those travelers will hit the road to reach their holiday destination. 

Travelers in the Northeast will be met by sunny, dry and mild weather through Friday, Weather.com reported on Wednesday. ABC News reported that temperatures will remain in the 50s and gradually get warmer as travelers head further south. However, a cold front is expected on Friday, with chances of showers in western regions.

In the South, holiday travelers will have a bumpier ride as coastal storms continue to affect parts of Virginia and the Carolinas. According to Weather.com, "A strong cold front passes through the region later Thursday and Friday with just a narrow band of showers or thundershowers." Temperatures around the region will be between 60 and 70 degrees, with slightly higher temperatures in southern Texas.

Some holiday travelers in the Midwest have been hit by dense fog, backing up traffic around the Chicago area, ABC News reported. That fog is expected to continue in parts of eastern Missouri to Illinois into northern Indiana and Michigan, Weather.com predicted. While temperatures in the area have reached highs of 60s and 70s, a cold front in the region on Thursday and Friday will make temperatures plummet to highs of 20s and 30s.

Residents in the Pacific Northwest will continue to experience some rainfall and snowfall. Weather.com predicts that no more than an inch of rain and up to eight inches of snow will hit the region. Temperatures in the Northwest will be slightly chillier than in the Southwest, ranging from 50s and 60s in the Northwest and 60s and 70s in the Southwest.

However, the National Weather Service has issued winter storm warnings and winter weather advisories for Idaho, Nevada and Montana. Additional high wind warnings and wind advisories are in effect for parts of Washington, Oregon, California, Nevada, Montana and Wyoming.
