Parts of northern Michigan are coming off one of the stormier days of the year so far Sunday.
Low pressure with quite a bit of cold air aloft crossed into an unstable air mass across Lower Michigan Sunday with thunderstorms quickly blowing up Sunday afternoon with some of them quickly becoming severe.
Trees were knocked over on a home and a vehicle with people inside just northeast of Gaylord with fortunately only minor injuries reported. Trees and power lines were also blown over in the Houghton Lake/Prudenville areas in Roscommon County. These storms were prolific hail producers with many areas seeing penny to nickel size hail. We had a report from Big Rapids that quarter size hail fell for about 6 minutes Sunday afternoon as the thunderstorms passed through there. While a few tornado warnings were issued, as of Monday morning no confirmed tornadoes were reported to have touched down over Northern Michigan.
While the rain and storm threat has ended for the time being, Northern Michigan will be stuck in the backwash behind this system much of this week with cooler than normal temperatures for the remainder of July right on into the first couple days of August. Our normal high should be around 80F but instead we will generally remain in the upper-60's to low/mid-70's much of the week with the cooler weather across the Eastern U.P. and right along the beaches of the Great Lakes.
Monday will be dry with 60's and a brisk north wind. Beginning Tuesday through the rest of this week there will be a small chance each afternoon for a few spotty showers/thunderstorms to develop in the afternoon heating as temperature aloft remain chilly. Any showers or storms will be tied directly to heating in the afternoon and will dissipate once the sun sets.
