Watches & Warnings

Special Statement
Issued: 4:21 AM CST Dec. 17, 2018 – National Weather Service

... Locally dense fog this morning in and near rivers and lakes...

If you are planning travel in and around The Purchase area of west
Kentucky this morning, be watchful for dense fog in and near
rivers and lakes.

Since midnight, satellite imagery and surface observations have
indicated patches of fog developing along a cold front moving
southeast through southeast Missouri, southern Illinois, and west
Kentucky.

As this cold front continues to move southeast through daybreak,
the cooler air riding over the relatively warm waters of the Ohio,
Mississippi, Cumberland, and Tennessee rivers will generate
locally dense fog in the vicinity of these bodies of water.

For travelers, visibility due to the fog will drop sharply as you
move on roadways and bridges near these bodies of water. This
will be especially true if you travel north and east of Ohio and
Mississippi rivers, as well as the Land Between The Lakes.

Some locations on the Tennessee and Kentucky border may also see
some patchy dense fog as well.

As the front finally moves through The Purchase area of west
Kentucky and extreme southern Illinois, visibilities due to the
fog should improve with time.

However, some locations may see locally dense fog persist until 9
am or 10 am this morning.

If you are planning travel and encounter fog, be sure to use low
beam headlights or fog lights. Leave plenty of room between
yourself and other drivers and signal any Lane changes ahead of
time so that other drivers can react in a timely manner.
