Snow and VERY COLD AIR!

It has been a pleasant day across most of Ohio today, and at times interesting. The whole state is in the 40s, with isolated rain, SLEET, AND SNOW showers, despite temps in the 40s. Here, just outside of Cleveland, it went from mostly sunny and 45 to light snow and about 40, then back to partly skies with temps around 43, all in about 20 minutes. These showers are popping up because we are slightly unstable, with temps a couple thousand feet up below freezing, but at the surface where the sun is out we are in the 40s. Tonight a strong cold front will be coming through. The southern 2/3 of Ohio may see a rain (maybe mixed with snow) shower, while the northern portion of the state will see a period of snow, adding up to a couple inches possibly because the snow will be enhanced a bit by Lake Erie. The front will also bring with it strong winds. Winds are already gusting to 35MPH, and those gusts will only increase tonight and tomorrow, and could reach 55MPH at times. Along with winds and snow, the front will bring in the coldest air of the season. Temperatures on Sunday will start in the 10s and possibly end up in the lower single digits, especially in NW Ohio. These will combine to bring wind chills to well below 0 from tomorrow morning through Monday morning across all of Ohio. Expect wind chills, especially in inland northern Ohio Monday morning to be close to -20. Those types of wind chills are dangerous to be outside in, so expect some school closings/delays Monday morning.
Although there ice on Lake Erie, there will be a moderate Lake Effect event on Sunday and Sunday night in the Snow Belt. The strong, warm winds and temps above freezing for several days have really acted to break up the ice and push it out over mainly northern Lake Erie, and the warm temps have really thinned out the ice, so with a lake/850MB temp differential of -25+, degrees C, even with some lake ice and dry air in place there will be lake effect snow showers, and possibly squalls. I don't think the snow totals will exceed 10" anywhere in the Snow Belt, but there will probably be a lot of reports of 4-7" across the Snow Belt. The snow should be really winding down by Monday morning.
Forecast Details: Tonight: Snow north, scattered rain/snow mix south. Windy. Up to 3" of accumulation north. Wind gusts to 50+MPH. Colder. Low 8-15 NW half of Ohio, and 15-28 SW half of Ohio. Sunday: Lake Effect snow showers NE, partly cloudy elsewhere. Windy and COLD. Temps falling into the single digits northern Ohio and into the lower teens southern Ohio. Wind chills as low as -15 by evening. Wind gusts as high as 50MPH. 3-6" of snow in the Snow Belt.
Sunday Night: Lake Snows starting to wind down, but 1-3" is possibly in the Snow Belt. Mostly clear outside of Snow Belt. Lows -3 to +3. Wind chills between -15 and -21 northern Ohio, and -12 and -15 southern Ohio. We could have a wintry system to deal with on Tuesday, more on that later.
