Special Weather Statement

Locally dense fog formed early today throughout the valleys of Central and Northern Pennsylvania, as a result of clearing skies, near calm air and a large difference of around 20 degrees between the air, river and stream temperatures.

The fog will reduce the visibility below one quarter of a mile in some places.

Allow extra time to travel to work or school this morning, and ensure that you keep plenty of braking distance between you and the vehicle ahead.

Visibility will improve as the fog dissipates between 9 and 10 AM.
