Metro Detroit weather forecast: 'The Calm Before the Warm'

Enjoy these comfortable days and nights before the heat arrives


Gorgeous sunshine, pleasant temperatures, and low humidity made for a spectacular Hump Day, and we’ll do it all over again on Thursday.  By the end of the weekend, however, many of you will be longing for these “good ol’ days”…

Wednesday night will be mostly clear and very comfortable…open the windows and enjoy some terrific sleeping weather.  Lows in the mid 50s (13 degrees Celsius).  Sunset is at 9:08 p.m.

Mostly sunny and a little warmer on Thursday, with highs in the mid to upper 70s (25 degrees Celsius).  A light east wind will help the standard lake breeze develop during the afternoon, so shoreline areas near the big lakes will be cooler.  Thursday’s sunrise is at 5:57 a.m., and Thursday’s sunset is at 9:08 p.m.

Mostly clear Thursday night, with lows in the mid 50s (14 degrees Celsius).

Partly cloudy Friday morning, then becoming mostly cloudy at some point during the afternoon with scattered showers and thunderstorms popping up.  Not everybody will necessarily get a shower or storm, but all of us are at risk.  Highs in the mid 70s (24 degrees Celsius).  I’ve already received an e-mail today about whether or not to rent a tent Friday evening for a graduation party, and I’ll tell you what I told him:  it’s always better to err on the side of being prepared…I would get the tent and rather be safe than sorry.  Even if you don’t get any rain, you’ll know that you were prepared in case it did rain, which takes that stress off of you…and is much better than the opposite scenario (not renting a tent, and then rain developing over your party).

Partly cloudy Friday night, with lows in the low 60s (17 degrees Celsius).

Partly cloudy and hot on Saturday, with highs in the mid 80s (30 degrees Celsius).

Mostly clear Saturday night, with lows in the mid to upper 60s (19-20 degrees Celsius).

Mostly sunny and hot Sunday, Monday and Tuesday, with highs generally around 90 degrees (32 degrees Celsius), and overnight lows generally around 70 degrees (21 degrees Celsius).

We stay hot on Wednesday, with highs in the upper 80s (31 degrees Celsius), but thunderstorms are possible.

Relief from the heat and humidity should arrive either Thursday or Friday.

Hot Weather Tips

Rather than wait for the heat wave to arrive before sharing these tips with you, I thought it would be a good idea to give them to you ahead of time.

  • Heat stress on the human body occurs when our internal temperature rises.  Obviously, if you have air conditioning, this won’t be too much of a problem for you.  However, those without air conditioning may find the going tough when the heat arrives.  If you can spend time at a relative’s or friend’s house, by all means start planning now to do that.  Or spend some of the day at air conditioned venues like shopping malls and theaters.  Another thing to do is take a cold shower or soak in a cold bath…that will very effectively bring down your core body temperature and make you feel more comfortable.  If you have a fan, just wetting yourself with a washcloth and standing or sitting in front of the fan will cool you off, as that breeze evaporates the water off your skin and makes you feel cooler.
  • If you have air conditioning, make sure that your furnace filter is clean so the furnace motor can run more efficiently and do a better job of pushing that cooler air through the house (I’m going to change my furnace filter tonight).
  • You have no idea how much hotter your place gets from sunshine coming in the windows.  Close your blinds and drapes during the daytime…that shade makes a huge difference.
  • If temperatures at night are comfortable, let that cooler air in through the open windows while you sleep, and then shut the windows and blinds/drapes as soon as you wake up so the rapidly rising outdoor temperatures don’t warm up your place earlier than they otherwise would.
  • If you are elderly or are in poor health, know your limits.  Heat stresses the body, so don’t overexert yourself.  Make sure to stay hydrated with water and sports drinks, and avoid alcohol (most people don’t realize that alcohol further dehydrates you).
  • Finally, if it’s too hot for you, it’s too hot for your pets.  Make sure they have shelter from the heat, and plenty of clean, cool water to drink.
