An American Airlines flight headed for the Bill and Hillary Clinton National Airport that was only  five miles  from  Little Rock has just turned around to return to Dallas because of heavy fog here. 

Shane Carter, the airport spokesman, said the airport, which has been socked in since early morning, did see traffic after 3 p.m. when the fog briefly lifted, but visibility is back down to pea soup again and he advises checking on any flights you plan to meet or take. The airport, which generally has 50 arrivals and 50 departures on a daily basis, has seen 29 cancellations (30 with the most recent report) so far today; there were no arrivals or departures before 3 p.m. Carter said there was a 12-hour period when visibility was down to 1/16th of a mile. 

The airport has one ILS (instrument landing system) runway and all general and commercial flights are using it. Carter — who happens to be a certified meteorologist besides being airport spokesman and said conditions are “a perfect set up for fog” throughout the evening and into the morning — said flights were diverted to Memphis, Northwest Arkansas, Dallas, Texarkana and St. Louis and a UPS plane had to land at Walnut Ridge.

UPDATE: Carter calls to say all Little Rock flights have been cancelled tonight and early tomorrow morning (in the 6 a.m.-7 a.m. range) because of the fog and the forecast for continued fog.
