As Texans celebrate the Christmas holiday, they are experiencing unseasonably warm temperatures, reaching near-record highs across the region. Many areas, including Dallas and San Antonio, are enjoying warm weather, with morning fog and sunny afternoons expected on Christmas Eve. However, forecasters are warning that a strong cold front is set to sweep through the state shortly after. This dramatic shift will bring potential freeze warnings and a sharp cooldown, with temperatures dropping significantly in the days following Christmas. Residents are advised to prepare for these big changes as they transition from summer-like warmth to winter chill.
