Metro Detroit weather: Lovely summer day before storms take over

Thursday highs in mid 80s with mostly sunny skies

Highs will be in the mid 80s and without the humidity -- a great summer day! In fact, a south wind blowing at 10 to 15 mph will provide a nice breeze to keep us comfortable.

DETROITGood Thursday afternoon!

If you need a summery day with no rain, today is your day -- and you’d better take advantage of it, because you may not get another one for a week.

We’ll have mostly sunny to partly cloudy skies for most of Thursday, with some increase in the cloud cover late in the day into the evening.

Highs will be in the mid 80s and without the humidity -- a great summer day! In fact, a south wind blowing at 10 to 15 mph will provide a nice breeze to keep us comfortable.

By all means try to get that lawn cut today, because you may not have a chance to cut it again for a while.

Today’s sunset is at 9:14 p.m.

Thursday night will become mostly cloudy, with a few showers possible later at night (our evening plans will be fine). Lows will be in the upper 60s and are indicative of the increasing humidity overnight. A south wind will move at 8 to 12 mph.

Rainy Friday

Scattered showers Friday morning will increase to even more showers and possible thunderstorms Friday afternoon, and especially Friday night.

Any thunderstorm Friday could produce strong wind gusts, and a near-record amount of moisture in the atmosphere means that torrential downpours are likely as well. Highs will be in the upper 70s to near 80 degrees.

Weekend forecast

Showers and possible thunderstorms are likely on Saturday, but probably will be more abundant in the afternoon than in the morning. Highs will be in the low 80s.

Sunday is actually a bit of a question mark, but in a good way.

Two computer models shove a persistent front farther north than they indicated yesterday, so we’ll be dealing with it more next week. If that verifies, we may get away with some dry weather for the first half (or more) of the day, before more showers and storms return.

However, other models keep the front farther south and, thus, keep a higher chance of rain around. It’ll be interesting to see how this plays out. If the first models win this forecast battle, then we’ll see highs easily reach the mid 80s on Sunday. If the second set of models win, then we’ll barely touch 80 degrees. Regardless, it will be humid.

By the end of the weekend, we’ll easily see one to two inches of rain. Any areas that receive a more persistent line of storms could see two to three inches. Rivers will be rising, so be aware that flooding may become a possibility.

No relief in sight

Put simply, this unsettled pattern will possibly persist all the way into next weekend.

There is a suggestion among the models that shower and thunderstorm activity could be more scattered Monday through Wednesday, and then become more widespread again after that. It’s looking like a rough go with the weather for the Rocket Mortgage Classic ... stay tuned.
