A strong cold front has now moved to the east of the area, allowing arctic air to spread southeastward across northeastern Ohio. Temperatures are falling, and will continue to fall throughout the day, reaching the upper teens by sunset.
Snow showers are developing across the area at this time, and this activity will continue through the day. It will also be quite breezy today with wind gusts in excess of 40 mph possible at times.
For tonight, a Lake Effect Snow Watch is in effect for Cuyahoga, Lake, Geauga and Ashtabula counties.
A secondary cold front will drop southward across northeastern Ohio late tonight. Once this front passes, winds will become well aligned out of the west-northwest. The colder air flowing over the unfrozen waters of Lake Erie will create extreme instability. Snow bands will intensify overnight with heavier squalls developing across the snow belt areas after midnight. Some locations could even hear a rumble of thunder. Lows tonight will drop to the low teens.
Monday will be breezy and cold with snow showers and squalls likely. Significant accumulations are possible across the snow belt. The snow will be dry and powdery, so significant blowing and drifting can be expected. Highs on Monday will only climb to the upper teens.
It will be very cold, with snow showers and squalls continuing Monday night and Tuesday. Additional significant accumulations are possible across the snow belt. Lows Monday night will range from 2 to 8 degrees with highs on Tuesday in the low teens. Wind chills Monday night and Tuesday could drop below -15.
From tonight through Tuesday, the heaviest snow is expected to fall from the Cleveland area, eastward into northwestern Pennsylvania. Some locations will pick up more than a foot of snow in this area. Lighter amounts are expected elsewhere across northeastern Ohio.
The cold and snowy weather will persist into Wednesday before high pressure builds across the area ending the lake effect snow.
