One positive to this current cold snap is that it should help the colors begin to change up North.
Frost and freeze warnings and advisories are in-effect tonight for sections of northern and Upper Michigan.
Although I haven't seen any reports of fall color up North, the first freeze always gets the leaves to change.
This image shows where the colors typically peak and when.
Notice that the color changes first in the interior western Upper Peninsula.
The last places to see the colors peak are along the lakeshore in parts of the Thumb, the west Michigan shoreline, and in the urban heat island of metro-Detroit.
After tonight's cold weather, a brief warm-up is on the way.
We will turn colder again behind a front on Monday, but temperatures will recover to near average and even above average for this time of year by the middle and end of next week.
