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.

Altostratus clouds form at mid to high-level altitudes
(between 2 and 7 km) and are created by a warm, stable air mass which causes
water vapor
to condense as it rise through the atmosphere. Usually altostratus clouds are
featureless sheets characterized by a uniform color.
In some cases, wind punching through the cloud formation may give it a waved
appearance, called altostratus undulatus. Altostratus clouds
are commonly seen with other cloud formations accompanying them.

Next Topic: Cirrus Clouds
Cirrostratus clouds are high, thin clouds that form above
20,000 feet and are made mostly of ice crystals. They sometimes look like giant
feathers, horse tails, or curls of hair in the sky.
These clouds are pushed by the jet stream and can move at high speeds reaching
100 mph.
What do they indicate?
They indicate that a precipitation is likely within 24 hours.
