It will be warmer on Father's Day, and a deterioration in air quality is expected in the Detroit metropolitan area

It’s going to be hot! You might be thinking, “That happens in late spring and summer.” True, but it doesn’t usually get this hot, this early in the season, and for this long.

Air quality alarm

An air quality warning has been issued for Sunday for St. Clair, Livingston, Oakland, Macomb, Washtenaw, Wayne and Monroe counties. Elevated ozone levels can make the air unhealthy “for sensitive groups” such as babies and pregnant women or people with respiratory diseases.

Due to the possibility of extreme heat and the forecast of heat indices of up to 38 degrees Celsius, 4Warn weather warnings have been issued for Monday and Tuesday.

Saturday night

Saturday night will be mostly cloudy with lows in the low 10s in the Thumb, mid 10s in the northern and western suburbs and around 15 degrees in Detroit, Downriver and Monroe. East winds will be around 5 mph.

Father’s Day

Sunday will be hot and dry. An air quality warning is in effect for much of southeast Michigan. With partly cloudy skies, temperatures will reach highs of 27 degrees in Detroit and much of the Detroit metropolitan area. In communities near Lake Erie and Lake Huron, temperatures will be below 27 degrees; and further inland, Adrian will likely reach temperatures in the high 27s. Winds will be from the southeast at 7 to 14 mph, with gusts up to 20 mph.

A warm front will move through the area and keep temperatures high Sunday evening. It will be partly cloudy with lows around 21 degrees. The wind will be from the south-southwest at around 8 km/h.

Monday

A 4Warn weather warning has been issued for Monday. Expect it to be mostly sunny and hot, with a few thunderstorms possible in the afternoon and evening. Temperatures will rise to over 35 degrees, which is about 15 degrees above normal. The record high for June 17 is 37 degrees (1994). When you factor in the humidity, it will feel like it’s about 38 degrees. With mostly cloudy skies, the nighttime weather offers little relief, with lows around 21 degrees.

Tuesday

A 4Warn weather warning has also been issued for Tuesday. It will be mostly cloudy and hot. A few showers and thunderstorms are possible in the afternoon and evening. Maximum temperatures will be between 35 and 35 degrees. The heat index will be around 38 degrees. At night it will be mostly cloudy with minimum temperatures between 21 and 25 degrees.

Juneteenth

The heat wave will continue on Juneteenth. Highs on Wednesday will again be in the 35 to 40 degrees. Temperatures could approach the record high of 35 degrees at Metro Airport for the day. Lows at night will only drop to 21 degrees with partly cloudy skies.

Thursday

On Thursday, the first day of astronomical summer, temperatures will be between 35 and 40 degrees Celsius. Skies will be partly cloudy with scattered showers, but most areas will remain dry. The summer solstice will occur at 4:50 p.m. On the longest day of the year, or the day with the most hours of daylight, the sun will set at Metro Airport at 9:13 p.m. At night, it will be mostly cloudy with lows around 21 degrees.

Friday

Similar weather conditions are expected on Friday. It will be partly cloudy with highs between 35 and 35 degrees. There is a chance of isolated showers. With mostly cloudy skies, lows will be around 21 degrees.

Saturday

The heatwave is likely to continue into next weekend, with highs of around 35 degrees on Saturday. It will be partly cloudy, with the possibility of some showers.

The combination of humidity, heat during the day and warmth at night can lead to heat stress. The effects of the heatwave will be particularly pronounced in the urban core, where there is more concrete and less natural landscape.

What is a heat wave?

In southeast Michigan, a heat wave is defined as three or more consecutive days of temperatures of 90 degrees or higher, according to the National Weather Service’s Detroit/Pontiac Forecast Office. In other parts of the country, particularly in heat-prone regions, different criteria apply.

Based on this criterion, the heat wave in the Detroit metropolitan area is forecast to begin on Monday and last throughout the week.

Tips for protection in heat:

• Stay indoors or seek shade

•Ensure adequate fluid intake and avoid alcohol and caffeinated drinks

• Reduce outdoor activities or limit them to the morning and evening

•Wear light, bright clothing
