A cold front will cross the area today accompanied by scattered, mainly light, snow showers and flurries. As the cold front moves east of the area tonight, winds will shift to the northwest and conditions will become increasingly favorable for lake effect snow showers.
The lake snows will really begin to kick in on Saturday as colder air at the surface and aloft spread southeastward across the area. The snows could be disrupted for a time by a disturbance that will cross the region Saturday afternoon. This feature will cause the winds to shift around and, in turn, cause the snow bands to become disorganized. However, winds will quickly realign out of the northwest behind this system later Saturday night and into Sunday.
Some locally heavy snow squalls will be possible Saturday and Saturday night with several inches of accumulation possible.
The snow showers will gradually taper off on Sunday, but it will remain cold through the weekend.
Early next week, a strong storm is forecast to track from the Mississippi Valley, northeastward to the Great Lakes. This system will bring a variety of weather to northwestern Pennsylvania including rain, snow, and wind.
