Earlier Reporting — November 8:

The National Weather Service issued a dense-fog advisory early Sunday, November 8, for parts of central and north-central Arkansas, warning that reduced visibility could make morning driving hazardous.

The Little Rock office’s 3:26 a.m. Central Standard Time bulletins forecast visibility of a quarter-mile or less. The advisory took effect when issued and runs through 9 a.m. CST Sunday.

The northern coverage includes Marion, Baxter, Fulton, Sharp, Stone, Izard, Independence, Cleburne and White counties. It also covers listed forecast zones in Boone, Newton, Searcy and Van Buren counties, with separate lower- and higher-elevation areas specified in the bulletin.

A companion notice covers Conway and Faulkner counties, southern Johnson and southern Pope counties, and the higher-elevation forecast zones in Johnson and Pope.

A separate frost advisory continues through 9 a.m. in parts of the central and north-central area covered by the first bulletin. Temperatures as low as 33 degrees Fahrenheit could lead to frost formation there. That frost forecast is not included in the companion Conway–Faulkner–Johnson–Pope fog-only notice.

The weather service advises drivers encountering fog to slow down, use headlights and leave plenty of distance ahead. For areas under the frost advisory, its instructions call for protecting tender plants.

Sunday’s notices describe expected low visibility and cold conditions within their stated forecast zones. They do not establish that visibility has already fallen to the same level throughout every covered county.
