Dangerous heat, poor air quality again on Tuesday in Metro Detroit

High temps to feel like middle, upper 90s on Tuesday

Here is the weather forecast for Metro Detroit.

DETROITGood Tuesday morning!

It’s our second day in a row under an air quality alert, also known as an Ozone Action Day, in Metro Detroit.

There was not much relief from the heat overnight. Temps start in the middle 60s to near 70 degrees with mostly clear skies as you head out.

The humidity has been creeping up and will continue to do so today and tomorrow. So, it will be hot and humid with very difficult breathing air for some.

The real trouble starts as the sun begins to warm us up quickly.

Today’s sunrise was at 6:14 a.m.

Air quality diminishes on days like today, because we have sun, warm air, light wind, and stagnant pollution at the surface. The chemical reaction in that combination creates ozone levels that can cause harmful health effects.

People and businesses should take action to reduce emissions of pollutants. Other than the universal sound of air conditioners running today, we won’t see or hear much with sun and clouds and highs near 90 degrees. There’s enough humidity to kick the heat index temps up five or more degrees, feeling more like the middle and upper 90s.

Listen to your bodies and stay hydrated. Our main concerns are for those who must work outside today.

Winds will be on the lighter side today, moving WSW at 5-11 mph.

Our North Zone is included in a marginal risk category for severe weather for storms moving in from the north later tonight. Those in the Thumb may see a few storms capable of damaging winds and dangerous lightning with downpours later tonight.

Tonight’s sunset is at 9:05 p.m.

Scorching hot Wednesday

Wednesday will be another scorching hot day with a steady and warming wind moving SW at 10-20 mph, gusting to 30 mph. That wind will aid in warming us into the low 90s, and hopefully mixing the air enough to eliminate the air quality alerts.

Early afternoon temps will feel closer to triple digits, creating that dangerous heat -- so don’t overdo it.

Next, our concerns go from the steamy weather Wednesday to storms possible with a passing cold front late in the day. The Storm Prediction Center has Metro Detroit in a marginal risk category for severe weather, which is the weakest risk category. Still, storms will fire in the heat of the day in a line moving northwest to southeast, primarily between 2 p.m. to 7 p.m. Wednesday, and possibly into the evening.

Not everyone will see storms or get a free lawn watering, but we should all keep an eye to the skies late in the day Wednesday.

Temps drop some

Thursday and Friday will still be quite hot, just not as humid. These look like classic beach or pool days if you’re thinking about making some fun summer plans. Highs will be near 90 degrees both Thursday and Friday with breezy conditions and manageable mugginess.

The weekend is showing signs of scattered showers both afternoons, but neither appears to be a washout. Saturday will be warmer with more sun in the upper 80s. Sunday will stay in the middle 80s with partly sunny skies and a spotty shower or two.
