4Warn Weather – Southeast Michigan will be under both an Air Quality Alert and a Heat Advisory Wednesday. Here’s the breakdown of each.
Heat Advisory
An upper-level ridge remains in place, funneling heat and humidity into a good portion of the country.
Many states are under heat alerts, including Michigan.
A Heat Advisory is currently in effect for all of Southeast Michigan and has now been extended until 8 p.m. Wednesday.
High temperatures both today and tomorrow will reach the mid 90s to near 100°, and heat index values will be closer to 100-105°.
Temperatures at night will only fall to the lower 70s. This will offer little relief for those without central air.
Highs on Thursday will be only slightly cooler, in the low 90s, with highs near 90° on Friday and Saturday. Sunday we’ll have more mid-80s.
We’ll see plenty of sun over the next couple of days with some additional clouds arriving Friday.
The next chance of rain will be Friday night, with chances carrying into the weekend.
Safety Tips: stay hydrated; take breaks in air conditioning or in the shade if working outdoors; check on those sensitive to the heat; stay hydrated; take breaks in air conditioning or in the shade if working outdoors; check on those sensitive to the heat; and do not leave children or pets in a vehicle for any amount of time.
Air Quality Alert
As air flows around the ridge that’s bringing us the heat, it will also direct our airflow in from the north.
Unfortunately, Canada has multiple wildfires, and the air moving in will be very smoky. An Air Quality Alert has been issued for the entire state Wednesday.
Smoke plumes will move into the Upper Peninsula this evening, into the Northern Lower Peninsula overnight, then into Mid-Michigan by Wednesday afternoon.
Smoke plumes will reach the southern state borders by Wednesday evening.
Smoke will have elevated particulate levels, making the air unhealthy for sensitive groups.
Safety Tips - Keep windows closed, run central air with high-rated filters, avoid strenuous outdoor activities, check on those with respiratory conditions, and watch for wheezing, coughing, chest tightness, dizziness, or burning in nose, throat, and eyes.
