...PATCHY DENSE FREEZING FOG...

Patchy fog has developed across much of the region, especially in
valleys and other low lying areas. While visibilities may be
variable, some fog is locally dense with visibility less than one
quarter mile. Temperatures in many of these locations have fallen
into the upper 20s and lower 30s, which could result in freezing
fog. Any residual moisture from Thursday's rain could also result
in icy spots. Expect the fog to gradually erode by mid morning.

If driving early this morning, be prepared for rapidly changing
conditions. Slow down, increase following distance, and use low
beam headlights when encountering dense fog. Any road surfaces
which appear wet may actually be icy.
