Special Weather Statement issued January 27 at 8:23PM CST by NWS Huntsville AL

Patchy freezing fog has developed across portions of north central
Alabama, northeast Alabama and southern Middle Tennessee this
evening, with visibilities generally in the 1-3 mile range. As
temperatures continue to slowly fall below freezing, the risk for a
very thin glaze of ice to be deposited on elevated surfaces will
increase through early Tuesday morning. At this point, the freezing
fog appears to be confined to larger valleys in the region.

Stay tuned to NOAA Weather Radio, or a favorite local media outlet,
for further statements or updates from the National Weather Service
in Huntsville.
