Very cold air is in over the state today, and it will produce some snow. Lake effect snows will be seen today in far northeast parts of the state and just inland off the south shore of Lake Erie. In addition, we do see clouds and a little moisture setting up in far southern OH, south of US 50, and that can bring some minor snows as well. Accumulations over a dusting are not expected south (we even can see a bit of rain trying to mix in in spots), but we can see the lake snows bring slightly better snow potential.
For the weekend, a reinforcing shot of cold air is coming and we have a quick moving clipper like system that brings snows for Saturday. The lakes will enhance some of the snow up north, but we think there is potential for a coating to an inch over about 50% of the state on more insulated surfaces. If we include areas that just see snowflakes through the day, coverage of this event can increase to 70%. This is not a big snow accumulation event, but the chances of snow look better. We see better sun chances on Sunday, and it will not be as cold.
Snows are back on Monday. The northern half of the state sees better snow chances in our forecast this morning. In fact, if the current moisture projections hold, we could see several inches in spots from I-70 northward next week. We will put potential snow totals out tomorrow for the event. Coverage will be nearly 80% of areas from I-70 northward on Monday. Then Monday night through Tuesday, we see the snow intensity drop, but coverage expands to nearly 75% of the state seeing some kind of snowflake action for the period through Tuesday.
Scattered snow showers will be around with no more than 30-40% daily coverage each day from late Wednesday through Friday. This is just a cold pattern, and the cold is leading to better chances of light snow. Still, we don’t think we are looking at major snow piling up over the next 10 days. The map above is cumulative snow total potential over the coming 10 days. These kinds of totals mean that the snow will be very gradual through the period. We see scattered little bits of action here and there, more nuisance than anything else but it adds up. Temps will remain normal to well below normal through the coming 10 day period.
In the extended period, we still see nothing spectacular until we get closer to the 18th and 19th.
