A Lake Effect Snow warning remains in effect for the primary snow belt, with advisories in effect for Lorain and Trumbull counties. A wind chill advisory remains in effect for all of northeastern Ohio.
A single, intense lake effect snow band produced very heavy snowfall across the primary snow belt last night. Some locations picked up over a foot of snow overnight. Elsewhere, light snow showers and flurries were reported with limited accumulations.
Temperatures overnight fell to the low to mid single digits across the inland areas, and hovered near 10 degrees along the lake shore. Wind chills were below zero across the entire area.
Looking at the current radar imagery, there have been some changes from the overnight conditions. The single band of lake effect snow has been disrupted by a wind shift. Winds which were westerly overnight, have shifted to the west-northwest. This has caused the main band to split into weaker multiple bands. These bands are still capable of producing heavy snow, but not at the rate we saw last night.
The lake effect snow showers and squalls will continue throughout the day today as arctic air continues to pour across the unfrozen lake. There could be a little expansion of the snow this morning, but most of the heavy snow should remain confined to the snow belt. Outside of the lake effect areas, scattered lighter snow showers are possible with little accumulation. Highs today will be around 10 degrees, except in the mid teens near the lake shore.
Tonight, winds will shift to the west once again with more heavy snow possible across the snow belt. Elsewhere scattered lighter snow showers are possible. Lows tonight will range from -2 to 6 degrees.
On Wednesday, a weak disturbance will track across Lake Erie. This will cause the winds to turn to the southwest. Scattered snow showers are possible across the entire area, but the heaviest lake snows will shift into Ashtabula county eastward into northwest Pennsylvania. High temperatures on Wednesday will reach the mid teens.
Wednesday night, winds will shift back to the northwest and mid level moisture will increase. Lake effect snow will increase across much of northeastern Ohio. Lows Wednesday night will range from 6 to 12 degrees.
On Thursday, high pressure will build across the area. Lake effect snow showers will finally wind down during the morning with dry conditions expected for the afternoon. High temperatures on Thursday will climb to around 20 degrees.
The break in the snow fall will be short-lived. A storm system is forecast to move through the Ohio Valley Thursday night and Friday bringing widespread accumulating snow to all of northeastern Ohio. Stay tuned.
