W e close out July with very little change in the overall flow of the weather.
Cool low pressure sits over James Bay (south end of Hudson Bay) where it has been parked much of this week. Pinwheeling around this low are occasional weak disturbances that cross over Northern Michigan inducing very sporadic showers or thunderstorms.
This pattern set up shop Monday and will finally relax some by the middle of the weekend when showers will come to an end. Many of us have not had a drop of rain all week long especially in Lower Michigan west of US-131 where Lake Michigan has kept things more stable close to the lake preventing much if any showers there. Further inland though showers are possible each afternoon through Saturday along with parts of the Eastern Upper Peninsula.
In the short-term for Thursday, the better chances for showers and a possible thunderstorm will be tied to the Eastern U.P. with very little expected in Lower Michigan. We expect a few showers to develop after 1 p.m. along the M-28 corridor and then slowly push south with time this afternoon/evening into Chippewa/Mackinac counties. Nothing extensive is forecasted and by mid-evening these showers will quickly come to an end.
High temperatures Thursday across the viewing area will range from 66F at Sault Ste. Marie to 78F at Big Rapids.
