While extremely sporadic, there were a couple reports into the weather office this morning of frost early Friday.
We are at least a month away from the "normal" first frost of the season in our coldest spots but a few areas around Grayling did report some. A viewer wrote in with a low of 31F about 8 miles east of Grayling with another viewer calling in some frost on their picnic table south of Grayling. A few other chilly spots were Roscommon down to 33F, Raco in the Eastern U.P. At 35F and Kalkaska at 36F.
Still, these were the exceptions rather than the rule and most overnight lows were in the upper-30's or low/mid-40's across Northern Michigan.
Temperatures will climb into the low/mid-70's Friday afternoon with ample sunshine all day long.
The next chance for showers/thunderstorms arrives Saturday. Just about everyone in the viewing area will see rain at some point Saturday, but it will not rain all day long. A cold front will drop in with rain/thunderstorms likely across the U.P./Straits region first in the 6 a.m.-noon timeframe Saturday morning.
Northern Lower Michigan from the Straits south to highway M-72 will see rain in the 8 a.m.-3 p.m. window and locations south of M-72 between 2 p.m. and 8 p.m. Saturday afternoon/evening. Severe weather is not expected but a few storms could have heavy rain, small hail and some gusty winds. Highs Saturday will be in the mid/upper-70's although closer to 70F across the U.P.
Dry weather returns Sunday with high temperatures in the low-70's.
