Moderate Expected Observed

Special Weather Statement

Special Weather Statement issued December 3 at 1:05PM EST by NWS Wilmington OH
Dec 3, 1:05 PM Dec 4, 4:00 AM
Light snow is expected to develop across the area after midnight,
shifting to the southeast through the predawn hours. This band of
light snow will affect the region by the Thursday morning
commute, eventually pushing south of the area by mid- morning.

Minor snow accumulations of less than an inch are expected, but
cold ground conditions will allow for quick accumulation on any
untreated surfaces. The main impacts are expected to be reduced
visibilities and some slick spots on untreated surfaces.

Motorists should exercise caution. Plan extra time for the
Thursday morning commute.
