Gas Problem or Not? 2010 4D SE

Okay, I live in Texas and my part got hit by this cold! Freezing sleet, snow, and all! I swear my gas tank was at half full or close to it before I parked, now it’s reading at 1/4 full. (160 miles to E vs 80 miles to E on the little info thing) is this normal cause of the cold or do I need to panic about it?
