Special Weather Statement

Special Weather Statement issued March 16 at 7:47PM EDT by NWS Wilmington OH
Mar 16, 7:47 PM Mar 17, 12:00 AM
Scattered snow showers occurring across the area will slowly
diminish through the evening. These snow showers will continue to
cause brief reductions in visibility. In addition, as temperatures
fall, the snow showers could produce a light coating of snow on
roadways. This will result in the potential for some slick spots
to develop. Motorists should be prepared for changing conditions
this evening and exercise extra caution.
