Dense fog advisories greeted residents across parts of Texas and Oklahoma on Sunday morning, marking the start of a volatile weather pattern expected to bring severe thunderstorms to North Texas early this week before a cold front delivers seasonal autumn temperatures.

Dense Fog Advisories The National Weather Service issued dense fog advisories for areas extending from the Texas Panhandle through East Texas, including Rockwall, Kaufman, and Hunt counties east of Interstate 45.

While the Dallas-Fort Worth metroplex remained outside the formal advisory area, high moisture levels and low cloud cover reduced visibility across the region.
