... Fog expected again tonight... still the potential for some snow during the peak Thanksgiving travel time...
The fog across the area will gradually thicken during the night. The fog could become thick enough to reduce visibilities to below 1/4 mile at times late tonight. This will create hazardous travel conditions.
Anyone traveling overnight should be prepared for the fog... and plan accordingly. If you encounter a fog bank while driving on the Highway... always use your low-beam headlights and slow down to a speed at which you can safely stop if you encounter an animal or object in the roadway.
A storm system is expected to move across the area mid-week. The air across the area will initially be warm enough to cause the precipitation form the storm to fall as rain through Wednesday and perhaps Wednesday evening. However... colder air seeping into the area will cause the rain to become mixed with snow and maybe even change to all snow late Wednesday night and Thanksgiving morning. The changeover is likely to occur over central and north-central Wisconsin first... and over the northeast part of the state last.
The potential exists for a couple inches of snow Wednesday night and Thanksgiving morning. But it is still too early to pinpoint which part of the state... if any... is likely to experience significant travel impacts from the snow. Anyone planning to travel during the start of the Thanksgiving Holiday period should closely monitor later forecasts on this developing system.
