Low pressure over the northern Plains states will dive southeastward into the lower Ohio Valley on Tuesday. We will see some sunshine today, but clouds will increase tonight as the storm approaches form the west.
On Tuesday, clouds will thicken up as moisture quickly spreads across the area in advance of the storm. Some light rain and snow will develop during the afternoon. Temperatures at the onset of the event will be in the mid 30s, however as the precipitation falls through the drier air beneath it, the atmosphere will cool, and this will cause the precipitation to change to all snow by late in the day.
The storm will track eastward across southern Ohio Tuesday night while intensifying. The snow will increase in intensity, becoming heavy at times overnight. Some areas could see snowfall rates of over 1 inch per hour Tuesday night as strong lift and deep moisture spread east across the region. Based on the latest model data, the heaviest snow is expected to fall south and west of a line from Cleveland to Warren. North and east of this line, the snowfall amounts will drop off sharply. Of course, any shift in the track will shift the area of heaviest snowfall.
Widespread accumulations of 4 to 8 inches are expected with isolated higher amounts possible. Areas across the far northeast could see less.
The storm will move to the Mid Atlantic states on Wednesday taking the moisture with it. The steady snow will end during the morning, but some snow showers or flurries could linger during the afternoon as the winds turn northerly.
Fair weather will return for Thursday and Friday along with moderating temperatures.
