With the coolest temperatures this season slated to roll into town behind thunderstorms over the weekend, officials urge travelers to use caution on the road.

“Business always picks up for us when it's like that, we have a lot of wrecks,” Jacksonville Fire Chief Paul White said.  

About 42.5-million people nationwide are expected to travel this Thanksgiving, which is the highest number since 2007, according to an Associated Press report.

Sergeant Daniel Franklin with the Jacksonville Police said local drivers should prepare in advance to go slow in the bad weather and traffic.

“People need to take plenty of time to plan their route to where they're going,” he said.

According to the National Weather Service–Shreveport, residents can expect a sunny, dry, 69-degree high for Thanksgiving day, which is 13 degrees lower than last year's high, officials said.

According to weather.com, Thursday's expected high is still about 4 to 5 degrees higher than usual for Thanksgiving.

Friday will also warm up to 69 degrees, but a cool front is expected to make its way into the area during the evening hours with a 60 percent chance of thunderstorms.

The chances for rain will continue through Saturday, with an expected high of 59.

Sunday is expected to be a clear, crisp day with temperatures expected to reach 54 degrees.
