A Lake Effect Snow Watch has been issued by the National Weather Service for the snow belt areas from Cuyahoga county, east across Lake, Geauga and Ashtabula counties.
An arctic cold front has now moved east of the area and much colder air is spreading across northeastern Ohio. Scattered snow showers are already developing in the cold westerly flow, and this activity will increase through this afternoon. Temperatures will fall to the upper teens by late this afternoon.
It will be windy today as well with gusts in excess of 40 mph possible.
Tonight, a secondary cold front will move southward across the area. Winds will become better aligned out of the west-northwest as colder air at the surface and aloft spills southward across the lake. Instability over the lake will become extreme and snow bands will organize and intensify. Some of the heavier squalls could produce thunder and lightning. It will be breezy with areas of blowing snow. Lows tonight will dip to the low to mid teens.
On Monday, the lake effect snow showers and squalls will continue with the heaviest snow expected to fall across the snow belt areas east of Akron and Cleveland. Again, there could be a rumble of thunder in some of the heavier squalls. There will be areas of blowing snow as well. Highs will only rebound to the upper teens.
It will be very cold Monday night and Tuesday with lake effect snow continuing across the snow belt, with scattered snow showers possible elsewhere. Lows Monday night will fall to 0 to 8, then rise to the low teens on Tuesday. Wind chills during this time frame could drop below -15.
The snow showers will gradually taper off Tuesday night or early Wednesday as high pressure builds back across the area. It will remain cold however with lows Tuesday night ranging from -2 to 6, and highs on Wednesday in the mid teens.
