The extreme polar conditions from the past couple of days have been slowly spreading the east. Along with that, the core of this arctic air mass has also begun to shift east.
In its wake, more moderate temps in the 30s will begin to push up into the Great Lakes by the end of the week. For the first time in roughly 61 hours, temperatures finally worked its way past the below zero range and sat in the single digits above zero for part of the afternoon.
A storm system developing in the plains states will roll into the Great Lakes later in the day on Friday and continue into Saturday.
This system will begin to push milder air from the south northwards and into the Great Lakes forcing the bitterly cold air mass to the east by Friday. Highs should return back into the low to mid 30s by Friday.
However, the moisture associated with this storm could produce a combination of snow at night and a rain/freezing rain/sleet combination during the day on both Friday and Saturday.
Slightly colder temps will slide into the region at the end of the weekend with highs in the 20s for the first half of the week.
A fast moving clipper type storm will produce some light snow Monday night into Tuesday.
