A huge swing in temperatures will be the focus this weekend for the NASCAR race in Talladega on Sunday.
A massive cold wave that will be responsible for widespread frost and freezes this weekend will send a cold shot into Talladega, Ala. as well.
"Drivers will face a much different track on Sunday in comparison to Friday's practice," said meteorologist and racing enthusiast Eric Leister.
"Highs will be nearly 20 degrees cooler on Sunday in comparison to Friday and could affect one of NASCAR's most unpredictable tracks," added Leister.
Temperatures in the mid-80s will heat the track Friday afternoon for their practice round, but a cold front will move through the track Friday night. Highs will fall into the upper 70s on Saturday before bottoming out in the mid-60s on Sunday.
A mostly cloudy sky will accompany the cooler Sunday weather, but rain will not be a factor. Normal highs in Talladega for early October are near 80 degrees.
Storms, including Ana, are lining up over the northern Pacific, en route to the northwestern United States and British Columbia.
