Periodic showers and storms will accompany increasingly humid conditions across northern Michigan. Except for today, the better chances for rain will be at night, including both Wednesday night and Thursday night. Some fog will enter the equation as well. The warmest temperatures are expected Wednesday and Thursday, and in northern lower Michigan.
Heat and humidity will steadily build throughout the week, peaking Wednesday and Thursday. Although scattered showers and thunderstorms could slightly alter the exact high temperatures, the heat will still pose a risk—especially to sensitive groups and those without adequate hydration.
After a break for much of Wednesday, showers and thunderstorms will return Wednesday night. There is a growing potential for severe storms Wednesday evening and night. Damaging wind gusts and large hail are the main concerns. Be sure to stay up to date on the forecast as we come closer to this Wednesday.
Additional thunderstorms are expected Thursday afternoon and night. There is potential for heavy rainfall, damaging winds, and hail. Be sure monitor the forecast this week for the latest details.
