...PATCHY BLACK ICE AND SCATTERED SNOW SHOWERS CAUSING SLICK SPOTS
THIS MORNING...
A cluster of snow showers over southeastern Ohio and southwestern PA
and moving northeast could result in a quick inch of accumulating
snow and reduced visibilities. This along with patchy black ice due
to freezing fog could result in slick road conditions, especially
along untreated roads, bridges, and overpasses.
Be prepared for snow or ice covered roads. Slow down and allow extra
time when traveling. Please use extreme caution, especially on
bridges, overpasses and around curves. Allow plenty of stopping
distance and avoid braking suddenly.
