Dense fog is expected early Thursday, especially thick in low-lying rural areas. The fog is forecast to clear by mid-morning.

Widespread rain is expected to develop Thursday afternoon and continue through Friday evening. The forecast said some areas could receive up to 3 inches, with rainfall totals of 1 to 3 inches across the region and higher amounts possible locally. The forecast linked the moisture to Tropical Depression Vance and an upper-level weather system.

A flood watch covers the South Plains and Rolling Plains from 4 p.m. Thursday through 8 p.m. Friday. The forecast said there is potential for widespread flooding. Residents were urged to monitor weather updates and to avoid driving through flooded roadways.
