Lake effect snow continues to fall across the snow belt from just east of Cleveland, northeast through Ashtabula county. The snow has become a little less intense this morning, but it remains very persistent.
A weak area of low pressure will track southeastward through the Great Lakes today, while a disturbance tracks through the Ohio Valley. Winds will shift to the southwest today. This will cause the lake effect snow to lift northward with many snow belt areas seeing a brief break in the activity. The snow will probably continue across northern Ashtabula county through the afternoon.
Elsewhere, some lighter snow showers will be possible this afternoon as the Ohio Valley disturbance approaches.
It will be cold today with highs in the mid teens and wind chills below zero.
Tonight is somewhat complicated. The low over the Great Lakes will pass to our north while the disturbance to our south move to our east. The winds will become westerly this evening allowing for an increase in the lake effect snow across the primary snow belt from Cleveland east across Lake, Geauga, and Ashtabula counties. Late tonight, a cold front will drop southward across the lake. This will cause the winds to shift to the northwest or even north-northwest overnight. The lake effect snow showers will reorganize and reorient on the northwesterly flow. This will cause the snow showers to become more widespread with many areas receiving some snow.
There could be some accumulation as the snow/water ratios will remain very high in the cold air mass. The heavier snow will likely fall across the higher terrain from just east of Cleveland, east across the primary snow belt. With the northwesterly flow, portions of the secondary snow belt from Medina county eastward to Trumbull county could also see some accumulations.
There is also some uncertainty regarding any upstream connection to Lake Huron. High resolution models indicate the Lake Huron band could produce some heavy snow over the eastern portions of the area late tonight and early Thursday.
Lows tonight will be around 10 degrees.
Scattered snow showers will continue through Thursday morning. Then high pressure will finally build across the region bringing an end to our multi-day lake effect event. High temperatures on Thursday will climb to the upper teens to low 20s.
Thursday night, another storm system will drop southeastward through the Great Lakes while a secondary system moves through the Ohio Valley. Clouds will quickly increase Thursday evening with snow spreading across the area from the southwest after midnight. Lows will be in the single digits.
Friday will be cloudy with widespread snow across the entire area. This system will lack a good moisture source, but snow/water ratios will be high. Still it looks like a fairly minor event with a general 2 to 4 inches of snow expected across the area. Highs on Friday will be around 20 degrees.
There will be another brief period of lake effect snow Friday night and Saturday, but improving weather is expected by Sunday as high pressure returns to the area.
