Millions of Thanksgiving travelers may be forced to deal with snowy conditions this year. Unfortunately, winter weather advisories are in effect for 20 million Americans as we move toward the middle of Thanksgiving week. The warnings extend from Michigan to California. It could end up being a pretty wintery Thanksgiving on the West Coast this year. Other parts of the country are also going to see a taste of winter for Thanksgiving 2019. The good news is that some airlines are already jumping into action with waivers. Let's take a look at it all.

What are we looking at for weather this week? A storm that the National Weather Service is calling historic is currently moving toward parts of Oregon and California. It is expected that the storm will rival the strength of a Category 1 hurricane. What's more, winds will actually exceed hurricane force as the storm continues to move.

There are predictions that the mountains outside of Los Angeles could be covered in up to 2 feet of snow this week. Heavy snow is also expected for the Sierra region. Snowy conditions will likely last from Tuesday to Friday. The rest of Southern California is also facing some serious weather this week. More than 10 million people from San Diego to Anaheim are under flood watches right now. Officials are warning that flash floods could make conditions dangerous as residents and travelers throughout Southern California anticipate Thanksgiving.

Denver will likely see between 10 and 15 inches of snow over the next few days. The Midwest won't be spared during this round of storms. Minneapolis is likely to see between 8 and 12 inches of snow this week. Heavy snow is also headed for Michigan and Iowa starting on Wednesday of this week.

What should you do if it looks like you're heading into a storm this Thanksgiving week? Use caution! Make sure to check weather alerts and advisories before traveling through or to a spot that is being impacted by strong weather. You should also check for canceled flights before heading to the airport if you're flying to your destination this Thanksgiving. Delta is already issuing waivers for Denver and Minneapolis in anticipation of serious weather. United has also announced a waiver for Denver.
