Metro Detroit weather: Another stormy pattern looms on the horizon

Storm chances increase later this week

DETROIT - What a day. Abundant sunshine, temperatures between 75 and 80 degrees (24 to 27 degrees Celsius), and comfortable humidity made this a perfect summer afternoon. 

But don’t let your guard down…another stormy pattern appears to be setting up, and will likely impact the late-week and weekend period.

But before we get to that, tonight will be another fantastic sleeping night, with mostly clear skies, calm air, and lows dropping into the low 60s (17 degrees Celsius) in our Urban Heat Island, and into the upper 50s (15 degrees Celsius) in suburban locations.

From a sky cover standpoint, Tuesday will be identical to what we experienced today.  Temps will warm into the mid 80s (30 degrees Celsius), with a light southeast wind. 

Tuesday’s sunrise is at 6:13 a.m., and Tuesday’s sunset is at 9:06 p.m.

Mostly clear Tuesday night, with lows in the mid 60s (18 degrees Celsius).

Storm chances increase mid-week

Partly cloudy on Wednesday, and it’ll be a close call as to if we’ll destabilize the atmosphere enough to generate any scattered late afternoon or early evening thunderstorms. Of course, Wednesday evening is the big International Champions Cup soccer game at Comerica Park, and let’s just say that a thunderstorm wouldn’t exactly enhance the viewing experience. 

I’ll definitely keep a close eye on things over the next forty-eight hours. Highs Wednesday in the upper 80s (31 degrees Celsius), and you’ll notice the humidity starting to come up again.

IF any late afternoon or evening thunderstorms pop up on Wednesday, they should fade pretty quick around sunset, leaving us partly cloudy for the remainder of the night. However, it’ll be warm and muggy, with lows near 70 degrees (21 degrees Celsius).

Mostly cloudy, warm and humid on Thursday with a better chance of showers and thunderstorms.  Highs in the upper 80s (31 degrees Celsius).

Weekend storm chances in SE Michigan

As for the Friday through Sunday period, the models aren’t very clear on the specifics, but it appears that we’ll have periodic shower and thunderstorm clusters crossing the area. I don’t think it’ll rain all day each day, but we’ll have to wait a few days for the computer models to get a better handle on the timing of some of the meteorological features I need to monitor. 

Weekends are as important to me as they are for you, so I’ll definitely watch the developing model trends, and update you each day through the week. I’ll do the best I can to salvage at least part of the weekend for you…but no promises at this point.
