At 10:55 p.m., up to a half-inch of wet snow was beginning to accumulate on grass and vehicles. That was an increase from reports at 9 p.m. that weather radar was showing a snow-rain mix is hitting the areas of Mercer and Auglaize counties, from Celina east through Wapakoneta and Indian Lake, Storm Center 7 Chief Meteorologist Jamie Simpson said Monday night.
The temperature in the area is holding fast in the mid 30s, so roads are still just wet, he said. That could change far north during the 11 p.m. to midnight period, and later in the Dayton area during the 1 to 2 a.m. period when temperatures will be falling. Those falling temperatures will likely mean slippery driving and walking on untreated surfaces.
The snowfall is expected to end sometime around 2 a.m. far north, about an hour later in the Dayton and Springfield areas, and at about 4 a.m. far south, Simpson said.
Light rain showers started at about 2:30 p.m. in some areas and steadier rain did arrive between 5 and 6 p.m.
"We may not start to get road issues until very late evening north and after midnight in Dayton and Springfield metro areas," Simpson said. "There will be about a 3 to 4 hour time period of light snow, which brings the end at about midnight far north and 3 a.m. south."
Overnight temperatures will dip below freezing, so roads could be slick during the morning commute until daylight. Icy conditions are possible, especially on bridges and overpasses. Snow will be gone by sunrise.
"We should wake up to sun and temperatures in the 20s," Simpson said.
Tuesday morning will begin with wind chills in the teens. Temperatures will climb to a high of about 35 with wind chills in the 20s.
Wednesday will also be chilly and clear, with morning lows starting around 20 degrees. Afternoon temperatures will again reach the mid-30s.
Thursday will be sunny again but not quite as cold. Temperatures will start in the mid 20s and peak during the day in the mid 40s.
