A cold front moved through the eastern Great Lakes on Sunday, ushering in a colder, more January-like air mass. Temperatures today are much closer to where they should be for this time of the year.
The colder weather will stick with us for the remainder of the week. For most of us, it will be fairly quiet through Wednesday. The exception will be across southern portions of Ohio, northeastward through central and southern Pennsylvania where a little light snow is possible as a couple of waves of low pressure pass by to the south. The northward extent of the light snow is in question, but at this time it looks like most of the eastern lakes region will remain dry.
A clipper will drop southeastward through the Great Lakes on Thursday and Friday reinforcing the colder air and possibly providing the region with some snow shower activity. Even this looks to be fairly minor at this point in time.
With the colder air in place, it will feel much more like January, but this week is only a preview of what may be lurking ahead for next week.
Models are in fair agreement that a stronger clipper-type system will drop southeastward through the Great Lakes over the weekend, accompanied by an arctic cold front. This front will be the leading edge of what could be the coldest air so far this season.
With the arrival of the arctic air, the lake effect snow machine will likely ramp up, but the details of any potential snow events are impossible to predict this far out.
The cold weather will likely have some staying power, lasting through the end of January and into the month of February.
