Patchy dense fog will continue to be a concern heading into the early afternoon hours. Expect highly variable visibility reductions down to a quarter of a mile or less. Those traveling should be prepared for sharp visibility reductions across short distances. Also, frost deposition may cause isolated slippery spots on area roads. Use low beam head lights, slow down and allow extra time to reach your destination.

Dense fog will slowly lift and dissipate as the afternoon progresses, so the advisory will be allowed to expire at 11 am. However, continue to use caution if traveling and watch for localized visibility reductions heading into the afternoon hours.
