A pleasant Thursday for all, but sporadic rain showers arrive tonight
A brief period of high pressure will allow a rather pleasant Thursday across northern Michigan, with a good amount of sunshine (especially the first half of the day) and moderating temperatures back near normal. Daytime highs will mostly top out in the middle to upper 50s, but a few spots in the N. Lower will reach the lower 60s under a southwest wind. Throughout the afternoon and evening, high-level clouds will gradually increase, in response to an approaching weak disturbance from the northwest.
The above mentioned disturbance works through the region Thursday night, along with its attendant cold front, bringing the chance for scattered showers. Showers will work through the region in a west to east fashion, but many will see little in the way of appreciable rainfall. Low temperatures will bottom out in the 30s, and it is not out of the realms of possibility that a couple snowflakes mix in, but nothing that will stick.
By the end of Friday morning, the cold front will swing through, ending the shower activity. There will be a break in the action during the afternoon, before a secondary disturbance pushes through the Great Lakes towards the evening and Friday overnight period. Friday's daytime temperatures will be chillier with the cold front passage - 40s to near 50 degrees which is below normal for late-April. As like the first disturbance, the second wave will only bring scattered, light shower activity with the possibility of a few snowflakes mixing into the batch. Any lingering shower activity will push out of northern Michigan by Saturday morning.
While Saturday will be quite chilly (widespread 40s), a significant moderating trend will be on the way towards the end of the weekend and into early next week. High temperatures climb into the 50s on Sunday, with widespread 60s and 70s expected Monday and Tuesday. Dry weather under high pressure will be the theme through Monday, but chances for rain increase by the middle of the next week.
