Metro Detroit Climate: Nearing 90° Friday
DETROIT – Dew points fell in the upper 50s to the lower 60s (15 to 16 degrees Celsius) as a drier air mass temporarily moved south. These lower dew points allowed for a commensurate drop in temperature, and most of us (mostly outside of our Urban Heat Island) dropped into our 60s (18-20 degrees Celsius) overnight.
We finally begin our Friday with mostly sunny skies, then it will be partly cloudy. Temperatures that afternoon should climb into the upper 80s (31 degrees Celsius), which, when combined with higher dew points that return as the more humid air mass creeps north, creates the chance for a single shower or late afternoon thunderstorm brings. Most high-resolution models this morning give the storm initiation time as approximately 5:00 p.m. to 6:00 p.m., with activity subsiding at 8:00 p.m. So most of us are not getting the much-needed rain and we should be fine at Comerica Bank Free Prix Day on Belle Isle. On the flip side, I have a friend who is getting married at 5:30 p.m. in an outdoor ceremony so things are more optimistic from her point of view! Except for the heat, of course. But she can withstand the heat as long as it doesn’t rain. The winds today will be weak and will generally blow from either the northeast or the east, at a speed of 4 to 8 miles per hour.
Today’s sunrise is at 5:57 a.m. and today’s sunset is at One After 909 (that’s 9:10 p.m. if you’re not a Beatles fan).
On Friday nights mostly clear to partly cloudy, with lows in the mid to upper 60s (19 degrees Celsius) and calm air.
Partly cloudy in the first half of our Saturday, then an approaching cold front on Saturday afternoon triggers isolated thunderstorms into the evening. In the storms with the heaviest downpours, a stronger gust of wind cannot be ruled out, but I do not expect a large-scale storm. Damp highs in the mid to upper 80s (30.5 degrees Celsius). If you’re heading to the Grand Prix, be sure to keep an eye on our real-time radar in the Local4Casters app, the nation’s best weather app. If you’re one of the few who don’t have it, just search “WDIV” in the App Store… it’s right there and best of all, it’s free!
We can still see a few isolated showers on Saturday night, with lows in the mid-1960s (18 degrees Celsius).
On Sunday then partly cloudy to mostly sunny, with pleasant humidity and maximum values up to the mid-80s (30 degrees Celsius) … a terrific day at the Grand Prix!
Mostly clear Sunday evening, with lows in the low 60s (16 to 17 degrees Celsius).
An upper level disruption crossing the state on Monday could trigger some showers and thunderstorms, so your flag may get wet if you hang it up on flag day. Highs in the mid-80s (29 degrees Celsius).
Finally – relief!
We finally get some relief from the heat, as a cooler air mass is moving in for Tuesday and Wednesday, with mostly sunny skies on both days and highs in the upper 70s (26 degrees Celsius). That’s what I’m talking about now! Night lows are also becoming much more pleasant, so we can also get nice sleeping weather out of the deal.
But then we heat up again
Thursday is mostly sunny, and the heat returns when the highs go back to the mid-80s (30 degrees Celsius).
On Friday it is partly cloudy, an approaching cold front brings some thunderstorms with it … we take the rain. Highs in the mid-80s (30 degrees Celsius).
For the time being, the next weekend looks spectacular, with pleasant humidity, highs around the 80s (28 degrees Celsius) and mostly sunny skies. Stay tuned!
