...Freezing Rain Changing To Light Rain Tonight...

Temperatures have warmed to near freezing over the past few hours
and are expected to rise above freezing by midnight. Until then,
a mixture of freezing rain and light rain is expected. This will
prolong ongoing hazardous driving conditions for locations along
and south of Route 24 in northern Indiana and northwest Ohio.
There will be a period of time after precipitation has changed to
light rain where ice will continue to be present on roadways and
elevated surfaces. Motorists should continue to monitor road
conditions and slow down as black ice is possible, especially on
untreated secondary roads. Give yourself extra time to get to your
destination and allow for extra breaking distance.
