Low pressure will move through the Tennessee Valley today and into the Mid Atlantic states tonight. Clouds associated with this system have overspread the area, but the precipitation should stay to our south. The clouds will likely thin out a bit this afternoon allowing for some partial sunshine, especially across the northern areas. High temperatures today will be in the mid to upper 30s.
As the storm moves to the east of the region tonight, high pressure will build across the area bringing clearing skies. Overnight lows tonight will fall to the mid 20s.
The high will move to our east on Thursday as a clipper-type system moves southeastward into the Great Lakes. A mild southwesterly flow of air between these systems will develop across northeastern Ohio. This will help temperatures to rise into the 40s. A few rain showers are possible during the afternoon as the clipper moves closer to the area.
The clipper will pass by to our north Thursday night, dragging a cold front eastward across the area. Scattered rain showers will likely change to snow showers Thursday evening with snow showers continuing overnight. Some light accumulations are possible. Overnight lows Thursday night will fall to the upper 20s.
On Friday a secondary cold front will cross the area ushering in a colder surge of air. Snow showers are likely across the entire area as the cold front moves through. Conditions over the lake will become quite unstable and lake effect snow showers and squalls will develop across the snow belt during the day. Temperatures will rise to the mid 30s during the morning, then fall during the afternoon.
Lake effect snow showers and squalls will continue Friday night and Saturday, especially across the snow belt. Lows Friday night will be around 20 degrees with highs on Saturday in the mid 20s.
The snow showers will persist downwind of the lake through at least Sunday morning before high pressure can build across the area.
