Metro Detroit weather: Tons of sun Wednesday with temps in the 70s

Mostly clear with patchy fog Wednesday night

By Paul Gross - Meteorologist

DETROIT - What a day! Abundant sunshine and low humidity have made Wednesday the perfect late spring day, as temperatures rise into the upper 70s (26 to 27 degrees Celsius) with light and variable winds.

The light winds will allow a Lake Huron lake breeze to develop, so parts of the Thumb closer to the lake will be cooler Wednesday afternoon.

Wednesday's sunrise was at 6:05 a.m., and sunset is at 8:56 p.m.

It will be mostly clear Wednesday night, with just some patchy fog. Lows will be in the mid-50s (14 degrees Celsius) with calm air.

Clear skies Wednesday mean that we'll be able to see a prime pass overhead of the International Space Station. Just look low in the west-southwest at 10:18 p.m. and you'll see a bright "star" fade into view. The "star" will then take the next six minutes to travel to the northeast, where it will fade from view. Remember that our hometown astronaut, Drew Feustel, from Lake Orion, is aboard and will be looking down on us.

It will be mostly sunny Thursday with highs in the low to mid-80s (28 to 29 degrees Celsius). Thursday night will be mostly clear with lows in the upper 50s (15 degrees Celsius).

Friday will be mostly sunny with highs in the mid-80s (30 degrees Celsius).

The Holiday Weekend

As mentioned yesterday, a more humid air mass will overspread the Great Lakes this weekend, so this will make the atmosphere more unstable.  We’ll have mostly sunny to partly cloudy skies both Saturday and Sunday, with random pop-up thunderstorms possible each afternoon.  Since a weak upper level disturbance will cross Michigan on Saturday, there’s a chance that any storms that pop up that afternoon will be more numerous than on Sunday.  Expect muggy highs both days in the mid 80s (30 degrees Celsius).

Expect more of the same on Memorial Day, although there’s probably a smaller chance for a pop-up storm in the afternoon.  Highs again in the mid 80s (30 degrees Celsius).

READ: What exactly is a pop-up storm anyway?

You’ll likely be outside for some of the upcoming holiday weekend, so here are a couple of important reminders.  First, since there’s a thunderstorm chance each day, check the customizable radar page in our FREE app if you have outdoor afternoon plans, such as at Volvik Championship at Travis Pointe Country Club in Ann Arbor, or the Movement Electronic Music Festival on Hart Plaza.  It’s the best way to stay ahead of the weather.

Also, since we’ll have plenty of sun, don’t forget the sunscreen!  We’ve just come out of a long winter and cold April, so we have no tan base, and can burn very easily if exposed to too much sun. There’s a reason we meteorologists call the Friday before Memorial Day weekend “Don’t Fry Day."

Next Week

Summer-like conditions continue all the way through next week, with highs remaining above 80 degrees (27 degrees Celsius).  Expect a lot of sun Tuesday and Wednesday, with more pop-up storms possible Thursday and Friday.
