A Winter Storm Warning has been issued and expanded to include the entire Miami Valley starting at 4 a.m. Saturday through 4 a.m. Sunday.
- Winter storm moves in Saturday
- Wind gusts up to 35-40 mph late Saturday
- Arctic air sets up Sunday
Overnight: Expect cloudy and cold conditions overnight with temperatures falling through the 30s, Storm Center 7 Chief Meteorologist McCall Vrydaghs said. It will stay dry through the night with a wintry mix of snow, sleet and freezing rain approaching from the southwest by morning.
Saturday: Another winter storm arrives, with this one bringing a higher chance for mixed precipitation, with snow, sleet and freezing rain during the morning hours. North of I-70, especially north of U.S. 36, will likely start and end as snow.
A Winter Storm Warning goes into effect at 4 a.m. for the entire region.
A push of warm air will keep the threat south of I-70 for a mix of sleet, freezing rain and rain for part of the afternoon. Cold air pushes back into the evening as precipitation picks up in intensity, which should bring all areas back to snow to end the event.
Expected snowfall is 6 to 10 inches for areas north of I-70, with some locally higher totals possible.
Dayton and areas south could see freezing rain first, resulting in ice accumulations ranging between one-tenth and ¼ inch. Snow totals will be between 4 and 7 inches, whereas Butler, Warren, and Clinton counties have a better chance to see 2 to 4 inches.
One thing to note about snow totals, there might be a shift of where the most intense band of snow sets up. This could, especially in the evening, bring a quick couple of inches to uptick some of the southern Miami Valley to higher totals.
Wind will be a factor in the storm, too, with gusts ranging between 20 and 25 mph during the day and 30 and 40 mph at night. This will create blowing and drifting snow, as well as reduced visibility and possibly sporadic power outages.
Sunday: Heavy precipitation will be out of the area by sunrise. Quiet, cloudy, and very cold during the day. Arctic air moves in with high pressure bringing temperatures down into the teens during the day.
It will still be breezy, so wind chills are likely going to stay below zero all day.
Monday: The coldest morning we've seen so far will start the workweek. Temperatures will be a couple degrees above and below zero. The wind chill will be between 10 and 15 degrees below zero. Expect sun and scattered clouds with highs around 12 degrees.
Tuesday: A dry and chilly start to the day with temperatures in the single digits. Highs will reach the mid-30s. Another storm system will move in, bringing rain showers that end as snow into the night.
