Special Weather Statement issued February 16 at 9:30PM EST by NWS Louisville KY

Subfreezing pavement temperatures tonight will lead to refreeze
of any residual water on untreated roads resulting on areas of
black ice. Be aware that any additional minor snow accumulation
will aggravate road conditions. Motorists should exercise caution
tonight and during the Monday morning commute, especially driving
on bridges and untreated roadways.
