News » NWS: Frequent spring fog not unusual
Mar. 11, 2010
A meteorologist says while it has been really foggy lately in the Appleton area, it isn't too unusual to have to deal with stretches of dense fog in the spring.
Jeff Last of the National Weather Service says during this time of year, the snow is melting and mild air is moving in from the south.
Last says fog forms when the mild air moves over the cold ground. He says that causes the moisture in the air to condense and create a ground-level cloud. |
