Why is the airport closed?

In a noon bulletin, the Weather Center at the Municipal Airport reported that the airport had been closed this morning due to the heavy fog that rolled in overnight. The fog is expected to lift by early evening when cooler air moves into the area, and planes will be allowed to take off and land then. Many of today’s flights have been canceled. Passengers who have tickets on a flight today should call their airline before leaving for the airport to find out whether their flight has been canceled. More poor weather conditions are expected over the next few days, and all people with air travel plans this week are advised to contact their airline to find out the status of their flights.
