Cold air in today as moves across the state and sets up in southeast Ohio by this evening. Temps are below zero this morning in parts of NW Ohio Still, though, the story is what happens in terms of snow tomorrow.
Snow moves back into northern Ohio tomorrow morning and continues through the day. Models are at odds over this system, with one model saying 1-3 inches or perhaps slightly more in far northwest Ohio down to US 20. The other goes crazy, bringing 8-12 inch snow totals all the way down to US 30. The interesting thing is, the model that is usually overzealous on snow is the one being conservative, and the one that has the poorest track record at catching heavy snow events is the one that is going over the top. The answer likely lies in the middle. We look for snow to be in the 5-8 inch range from in NW Ohio 40 miles either side of US 20, and then lesser totals as you go south from there. This is truly a northern Ohio event, with nothing but flurries for your Friday south of US 30. This forecast is a step up from our previous discussions, but likely does no go as far as some other forecasts you may here today. In either case, gear up, because there will be some northern snow of some kind in the next 48 hours. A second wave of action comes for Saturday and Sunday, binging another 2-4 inches to the entire state of Ohio.
Next week is drier, with bitter cold air in for Monday. Subzero temps are likely over almost all of the state north of I-70. After that cold start to the week, we have temps moderate a bit Tuesday, before clouds and colder air returns for Wednesday. High pressure dominates next Thursday and temps climb again on Friday. We do have some scattered light snow showers possible overnight Friday night into early Saturday, mostly over the northeast quarter of the state. On Saturday, we turn colder and drier again.
The extended pattern is more active again, with 3 systems in 5 days. One on the 18th brings rain mixed with snow, and liquid equivalent precipitation of a quarter to half inch. On the 20th we see half to 1 inch of moisture coming through (liquid equivalent) and on the 21st we can see 1-2 inches of liquid, potentially coming as mostly snow. Then we are dry and cold through the 23rd.
