As you prepare to celebrate Thanksgiving on Thursday, here are three surprising Texas ties to the holiday you probably didn't know.

The Transportation Security Administration predicts they will screen more than 18 million passengers between Tuesday and early next week. More than 3 million are expected to fly through Dallas-Fort Worth International Airport.

Thanksgiving Day across Texas will be mostly sunny and mild, according to forecasts from the National Weather Service. Travel weather across Texas on Thanksgiving Day appears rain free, with highs ranging from the 50s around Amarillo to the 80s in Brownsville. Dallas and most of West Texas will also see temperatures in the 50s on turkey day.

American Airlines expects to welcome more than 8.3 million customers systemwide between November 21 and December 3. Meanwhile, AAA projects 5.7 million Texans will head 50 miles or more over the Thanksgiving travel period.

The average price of a Thanksgiving dinner is down this year. That may be why those who produce turkeys and other holiday staples are seeing better-than-average business right now. The Cajun Turkey Company shipped out more frozen prepared Thanksgiving dinners than ever before on a single day.
