The CBS News Detroit weather team has declared Tuesday and Wednesday to be NEXT Weather Alert Days, stepping up forecasts and announcements as needed.   

Metro Detroit's forecast 

Dangerous heat and humidity will combine to push heat index values well into the upper 90s and lower 100s Tuesday afternoon.

The actual high temperatures are expected to climb into the upper 90s, near 100, making Tuesday the hottest day of the week for many communities in Southeast Michigan. Residents should limit strenuous outdoor activities during the peak afternoon hours, stay hydrated, and check on vulnerable family members, neighbors, and pets.

The intense heat will continue through Wednesday, but a gradual pattern change is expected later this week. 

Increased chances for showers and thunderstorms arrive Thursday into the weekend, helping to knock temperatures back into the 80s and providing a break from the oppressive heat and humidity.
