A Winter Weather Advisory remains in effect until 2 PM EDT Saturday.

* Timing...rain or rain and snow mixed will continue to change to all snow through around 2 am on Saturday. The snow is expected to change back to rain in the valleys on Saturday morning...but remain as mostly snow at elevations of 1000 feet and above through early Saturday afternoon.

* Impacts...roadways...especially those along ridge-tops and crossing the higher passes above 1000 feet...may become snow covered...slushy or slick...resulting in hazardous travel. Visibilities may be reduced at times to one half of a mile or less during periods of heavier snow and on the ridge-tops. An isolated power outage may also occur...as downed trees will be possible due to the snow accumulating on foliage still left on many trees.

Precautionary/preparedness actions...

A Winter Weather Advisory for snow means that periods of snow will cause primarily travel difficulties. Be prepared for snow covered roads and limited visibilities...and use caution while driving.
