DAYTON — Winter Weather Advisory cancelled for: Auglaize, Butler, Champaign, Clark, Darke, Green, Logan, Miami, Montgomery, Preble, Shelby, Warren
Roads in the Miami Valley region continue to be slick after being blanketed by snow Friday evening, following hours of rain and sleet earlier in the day.
However, snow will slowly taper off from west to east over the next few hours. But, gusty winds will create blowing and drifting of the snow through the night, even once the snow stops falling. This will create some rough travel, especially in rural areas.
With a bit of a faster end to the snow – it looks like total accumulations will range from one to three inches for areas along and west of I-75 but areas between 75 and I-71 could pick up closer to four inches.
Earlier in the evening, blowing and drifting snow and icy conditions led officials to issue level 1 snow emergencies for Clark, Champaign, Darke, Logan, and Montgomery counties.
Greene County is currently at a level 2 snow emergency.
Between two to four inches were expected from Friday into Saturday morning across most of the Miami Valley region, as temperatures dip into the lower teens.
The wintry mix of snow and sleet has transportation officials cautioning residents to stay off the roads except for absolutely necessary trips.
Throughout the evening, the Ohio Department of Transportation map showed vehicles traveling below normal speeds on all the major interstates and highways.
STAY ALERT: Dayton traffic from the WHIO traffic center
The snowy weather lingered in the eastern half of the Miami Valley headed into the evening hours Friday, but by about midnight, most of the region should saw a break in the snowfall, said Kirstie Zontini, WHIO-TV meteorologist.
But it will be cold, with the high temperature on Saturday being 19 degrees.
Saturday is expected to have some leftover flurries and dusty winds, with temperature dropping to about 5 degrees during the night, said WHIO-TV meteorologist Eric Elwell.
The bad weather caused problems for motorists.
A semi-trailer overturned on Interstate 70 in Clark County and a crash involving a medic at North Dixie Drive and Frederick Pike impacted traffic in Harrison Twp.
Traffic was light on many roads across the region by early evening, as people seemed to hunker down.
Earlier on Friday, the city of Dayton had 45 trucks on the road — nearly its entire fleet — salting highways, thoroughfares, bridges, hills and major connector streets, said Fred Stovall, Dayton’s director of public works.
“We want to make sure what we call our primary 1 and 2 streets are clear so everyone can get home,” Stovall said.
Crews will eventually get to the residential streets, but that may not happen until Saturday, depending on how much snow falls and collects, he said.
The city does not plow residential streets unless they have 4 inches of snow, but it does treat them if they have ice.
Temperatures are dropping, and the rain has turned to sleet and the wet roads are icing over, Stovall said.
The storm led to the canceling or the postponement of numerous events across the region.
The city cancelled all recreation events through Jan. 13, including citywide basketball and the MLK youth World House party.
Drivers should accelerate and deaccelerate more slowly during bad weather and drive a speed reasonable for the conditions, said Sgt. Mark Bowron, traffic reporter for WHIO Radio.
Braking on icy roads takes much longer than on dry pavement, increasing stopping times from three to four seconds to eight to 10, he said.

Don’t eat the snow! A study, published in 2016, claimed that eating snow is potentially dangerous, particularly in urban areas.
Dr. Parisa Ariya, a professor at McGill University in Canada, told The Huffington Post that snow in cities can absorb toxic and carcinogenic pollutants and that the snow itself combining with those pollutants can lead to even more dangerous compounds being released.
"Snowflakes are ice particles with various types of surfaces, including several active sites, that can absorb various gaseous or particulate pollutants," she said.
Ariya, who led the study, said she did not "wish to be alarmist," but "as a mother who is an atmospheric physical chemist, I definitely do not suggest my young kids eat snow in urban areas in general."
The study examined how snow interacts with pollutants from car exhaust in the air. Findings showed that snow pulled pollutants like benzene, ethylbenzene, toluene and xylenes from the air. The amount of pollutants concentrated in the snow increased dramatically.

— Snow turns into flurries overnight, Storm Center 7 Chief Meteorologist Eric Elwell said. Total snow accumulation is expected between 2 and 4 inches for most, with isolated higher amounts closer to the Interstate 71 corridor. Gusty winds will create blowing and drifting snow overnight. Temperatures will drop in to the lower teens by morning.
WINTER WEATHER ADVISORY in effect through 10 a.m. Saturday for entire region, except for Clinton County, which is under a Winter Storm Warning until 10 a.m. Saturday.

Saturday: Clouds will linger with a chance for flurries. Highs will hold in the upper teens with wind chills near zero.
Sunday: Skies will remain mostly cloudy. Temperatures will stay cold, only reaching into the upper teens.
Monday: Cloudy with snow developing. Some accumulation possible. Highs will be in the upper 20s.
Tuesday: Skies will be mostly cloudy with frigid temperatures only in the lower teens. Gusty winds will hold wind chills between minus 10 and minus 15.

— Despite being less than 36 hours away from the upcoming storm, there is still a wide disagreement on the impact of this system.
This has led to unusually low levels of confidence in snowfall amounts. It is because of the low confidence why our friends at the National Weather Service in Wilmington have held off on issuing any winter storm watches despite some of the surrounding offices doing so.
That all being said, here is what we are concerned about — it appears the incoming cold air will likely "undercut" the warm air Friday, causing precipitation to change from rain to freezing rain. My concern is a lot of the higher-resolution models which can make up on this type of set-up are increasing the threat for icing.
On the positive side, we will have a warmer ground than in days past to start with, so the icing may be delayed through the day Friday. The negative is once we get closer to sunset and temperatures continue to drop, that icing may become much more of an issue.
Here is my other concern — even though snowfall amounts seem to be dropping on the latest models, even a few inches of wet snow onto tree limbs and/or power lines coated in ice could become another issue all together. Plus, ice underneath snow creates a unique challenge to road treatment.
Also, there are still a few high-resolution models that are sticking with the higher snowfall amounts (6+ inches), so I still don't think we can rule out higher amounts.
But for now — I am thinking 2-4 inches is most likely, but that is on top of some ice. Combine that with gusty winds developing Friday night into Saturday and the impact of this storm will be just the same as a bigger snow event.
