... Patchy black ice expected tonight into early Thursday 
morning... 

As temperatures drop below freezing late this evening, any water 
running off from recent snow melt may re-freeze on area roadways 
that have not been treated. This could result in patches of black 
ice tonight into early Thursday. The temperature should climb 
back above freezing by mid morning on Thursday.

Be prepared for slippery spots on roadways tonight into early 
Thursday morning. Some roads that appear clear may be covered by a
thin layer of ice.

Monitor NOAA Weather Radio for the latest information, forecasts,
and warnings.
