Cold air continues to park over the state today. Winds out of the west/southwest this morning never really are able to moderate temps a whole lot today, and we actually look for lake effect snow to become more and more of an issue as the day wears on along the southern shores of Lake Erie. However, the rest of the state away from the lakes and south will be dry today. Clouds will mix with sunshine while the cold air stays. Then tonight and tomorrow the lake snows will interact with a minor low that moves across Michigan into Ohio overnight. Snows in the NE quadrant could be in the 2-5 inch range overnight tonight, and by sunrise tomorrow, we could see 60% coverage of some light snow over the state with minor accumulations. .
The minor snow bands continue off and on tonight through tomorrow, but will have coverage limited to only about 30% of the state at any given time. Additional accumulation will be limited to mostly lake effect areas, with the rest just flurries from time to time.
At midweek, we have a mostly dry day for Wednesday. But our next clipper system looks to arrive Wednesday evening, coming in from the northwest. The best snows will be overnight Wednesday night into Thursday. 1-4 inch snows are likely in a band 60 miles either side of a line from Van Wert to Athens. By Thursday noon, the action is basically gone. Coverage of snow will be roughly 70% of the state, with totals under an inch seen around the heavier snow band we mentioned above. The map above shows cumulative snow potential for everything from later this afternoon through Thursday evening.
Friday should be mostly dry with no frontal action moving in. There can be a few flurries in over the region here and there as cold air stays parked right no top of us. But, by Saturday we have good, strong southwest winds back, and that will help temps bounce a bit for the weekend. Temperatures Saturday and Sunday should max out in the upper 30s and to near 40.
We have a minor system moving across the southern half of the state overnight Sunday into early Monday. Precipitation can be a mix of rain and snow from I-70 southward, and we can see a few hundredths to .15” of liquid equivalent. Coverage will be 80% of the area south of I-70, and the northern half of the state sees basically nothing. Northern areas get their minor bit of rain ending as snow Monday night into early Tuesday. A few hundredths to .3” with 90% coverage north of I-70. Cold air returns behind that system. We actually see more snow showers in for Tuesday afternoon and Wednesday with minor accumulation
In the extended period, we continue to see a significant front arriving late on the 21st into the 22nd. This system has the best moisture with it along and ahead of the front, meaning we should see predominantly rain, then changing over to and ending as snow. There should be good coverage over the state. Behind that, we are dry through Christmas weekend, with snow trying to develop out of an upper level low coming through the great lakes Christmas night into the 26th.
