A Lake Effect Snow Warning has been issued by the National Weather Service for the snow belt areas from Cuyahoga county, east across Lake, Geauga and Ashtabula counties.
A very cold arctic air mass continues to settle southward across the region. A reinforcing cold front is currently moving across northeastern Ohio. This front has caused the winds to briefly turn to the west-southwest. This has allowed the lake effect snow showers and squalls to remain near the lake shore. Heavy squalls overnight produced several inches of snow over Lake county. The band that produced that snowfall will weaken this morning as it moves up the lake toward Ashtabula. Elsewhere, only scattered light snow showers or flurries are occurring at this time.
The forecast for the remainder of the day is somewhat complicated. The winds behind the front the is currently crossing the area will turn to the west-northwest by early this afternoon. The snow showers over the lake shore areas will become disrupted this morning, then reorganize on the west-northwesterly flow this afternoon. The snow showers should become more widespread this afternoon as the instability over the lake ramps up.
It still looks like the heaviest snow will fall across the snow belt from Cuyahoga county, east to Ashtabula county. Accumulations could be locally heavy, but will vary greatly from place to place. Elsewhere, accumulations will drop off sharply.
Temperatures today will rise to the low 20s this morning, then possibly fall a degree or two this afternoon as colder air arrives.
Tonight, a well aligned west-northwesterly flow will allow for the lake effect snow to continue. Tonight, based on the latest model data, the heavier snow squalls could shift southward a bit, impacting areas from Lorain and Medina counties, eastward to Trumbull county. It will be very cold tonight with high snow/water ratios. Where squalls persist, the snow could accumulate very quickly.
Low temperatures tonight will fall to 0 to 8 degrees with wind chills of -10 to -20. A Wind Chill Advisory is in effect for tonight and Tuesday morning for all of northeastern Ohio.
It will be very cold on Tuesday with lake effect snow showers and squalls continuing. The heaviest snow is expected to fall across the primary snow belt from Geauga county, east into Ashtabula county with lighter amounts elsewhere. Temperatures will recover little from the overnight lows. Highs Tuesday afternoon will only reach the low teens across much of the area.
Snow showers will continue Tuesday night and Wednesday as lake effect snows persist across the snow belt and a weak clipper moves across the state. Lows Tuesday night will range from -2 to 6 with highs on Wednesday in the mid teens.
