Weekend temperatures will be in the 70's, but a massive shot of chilly air will sweep in early next week with a few places perhaps setting record cold daytime highs next Tuesday.
Before that happens though, we will enjoy comfortable temperatures this weekend with 70's in the cards both Saturday/Sunday. There will also be a chance for showers or an isolated thunderstorm this weekend. A weakening cold front will approach the area from the northwest. That combined with southerly winds and a more moist airmass will be just enough to trigger showers and a passing storm or two. It certainly won't rain all weekend and there will even be a bit of sun mixed in for good measure, but if you have plans across Northern Michigan this weekend, take note that there could be a bit of rain.
All eyes then turn north to start next week as a deep trough of unseasonably cold air will develop on the west side of Hudson Bay and then drop south sending much of the Eastern U.S. into a cooler than normal weather pattern. This bubble of chilly air will center itself next Tuesday right on top of Northern Michigan preventing temperatures from really rising much at all. We may see a few lower-70's Monday, but by Tuesday daytime highs will freefall with temperatures stuck in the 50's and at best low-60's. These readings compare to near record cold mid-July high temperatures. This pattern will also be conducive to produce showers or even areas of drizzle. According to the National Weather Service, these are the current record cold high temperatures for July 15th (next Tuesday) at a few locations.

It won't last long however with temperatures rebounding late next week into the 70's.
