Cold & lake effect on Friday, with widespread snow arriving by Saturday
Winter is back in full force and doesn't let up throughout the extended period.
Lake effect snow continues throughout parts of Friday, but a shifting wind direction towards the west will diminish coverage and intensity over a centralized location by the afternoon. This should cut down overall totals during the day, but a light accumulation here or there in the lake effect snow belts still remains. One thing for all across northern Michigan - temperatures remain below normal for early February, topping out in the 10s. The northwest to west breeze puts wind chills near 0 degrees all day long.
Developing low pressure in the northern Plains begins to spread light to moderate snow into the region Friday night, and will also become lake enhanced under a west-southwest flow. For those closer to Lake Michigan, light to moderate snow throughout the night will lead to a couple more inches of accumulation. Lows in the single digits to lower 10s.
The above mentioned low pressure tracks nearly overhead on Saturday, leading to widespread snow across the N. Lower, and it will pile up in spots. With the system passing nearly overhead, lake enhancement bands will be hard to pinpoint down as winds will be shifting directions all day long. Expect travel to be slow and visibility to be reduced throughout the day - winter headlines are likely for at least parts of the viewing area as 2-7" appears to be the general theme. For the E. Upper, impacts appear less at this time, but light snow will still fall at times. Temperatures do climb slightly on Saturday, topping out in the upper 10s to lower 30s.
A reinforcing shot of cold air trickles in on Sunday, leading to more lake effect snow chances.
