An upper level disturbance will move across the region this evening. This feature is responsible for the widespread snow shower activity that is currently impacting the region. The snow showers will continue into tonight while gradually diminishing from west to east as drier air overspreads the area.
Snowfall amounts should be fairly light, except across the snow belt areas from northeastern Ohio to southwestern New York where some lake enhancement could augment the snowfall, producing amounts in excess of 4 inches in a few isolated locations.
Snow showers will linger across the eastern areas Thursday morning, but most locations should eventually see some sunshine as high pressure briefly builds across the region. This high pressure system will control the weather into Thursday night.
Then, another developing storm system in our active weather pattern will move from the upper Mid West into the lower Great Lakes Thursday night. Clouds will increase from west to east Thursday night as this system approaches.
The storm will strengthen and move east across Ohio Friday and into Pennsylvania on Friday night. Rain and snow will spread across the area from west to east on Friday. At this time, the best chance of accumulating snow will be across lower Michigan and western New York, with a mix of rain and snow expected across northern Ohio and northern Pennsylvania. Further south, mainly rain is expected.
As the system moves to our east on Saturday, precipitation will end, with dry but chilly weather expected for the second half of the weekend.
