Grand Rapids, Mich. – Michigan starts the week with late-September warmth, but October will quickly bring a cooler turn by midweek. Drivers along I-196 and U.S. 131 can expect clear skies and smooth commutes through Wednesday, but residents should prepare for fall-like changes as temperatures dip later this week.
According to the National Weather Service in Grand Rapids, Monday and Tuesday will stay sunny with highs near 81 to 82 degrees. Winds remain light, but gusts up to 18 mph could develop by Tuesday night, especially east of the city. Wednesday brings the first real taste of October, with partly sunny skies and highs topping out near 75 before dropping into the 40s overnight.
The warm, dry stretch means excellent travel conditions across Kent and Ottawa counties, but health officials advise caution for those sensitive to ragweed pollen, which remains elevated in the dry air. Farmers across West Michigan may benefit from the dry spell, with clear skies aiding in crop harvest.
By Thursday, cooler highs in the upper 70s settle in, paired with partly sunny skies and clear nights. Friday looks similar, but another cooldown may arrive over the weekend, with temperatures falling closer to 80 and cooler evenings signaling the shift deeper into fall.
The next chance for unsettled weather does not appear until early next week, but forecasters caution that patterns can shift quickly as October begins. Residents should monitor updates in case of developing advisories.
