A dense fog advisory remains in effect until 10 am CST Tuesday.

Dense fog is expected to quickly redevelop by this evening. As a
result... the dense fog advisory has been extended until 10 am
Tuesday. The fog tonight is expected to become increasingly
dangerous... with visibilities near zero at times. The most
persistent fog should be along the crest of the hillside adjacent
to Lake Superior... and higher points of the Iron Range.

Precautionary/preparedness actions...

A dense fog advisory means visibilities will be reduced to less
than a quarter mile in some locations. Rapid changes in
visibility from a few miles to only a few hundred feet may occur
over very short distances. If you are driving... slow down... use
low beam headlights and be prepared for the sudden loss of
visibility as you enter fog banks. Many deadly accidents happen
in instances where dense fog is not widespread... but where rapid
changes in visibility occur and drivers suddenly cannot see as
they drive into a dense fog bank.

... A record daily high minimum temperature was tied at Duluth MN...

The low temperature was 38 degrees at Duluth Minnesota yesterday.
This ties the record high minimum temperature for the date. The
original record of 38 degrees was set on November 22 1908.
