DETROIT – Our weather has been relatively quiet so far today, but that’s going to change later.
A scattered shower is possible late afternoon or evening, but I think a lot more people will be dry than wet for outdoor plans, including at Comerica Park. Still, you need to be prepared for rain just in case you’re one of the unlucky ones. At this point, it appears that the better chance to get one of these showers is north of 8 Mile but, again, this will be scattered activity -- not everybody will see a shower.

Tonight, however, a more substantial line of showers and storms will develop and track across the state, and there is some potential for severe weather with these storms. One key will be a warm front draped from east to west across the southern part of the state. Based upon all of the forecast soundings I’ve been looking at this afternoon, it appears that the better chance for stronger storms is south of the front where the air will be warmer and more unstable, which makes it easier for violent updrafts to develop and create strong storms. The probability of seeing a tornado is very low.
However, damaging wind gusts and marginally severe hail are possible if the storms become robust enough. Thunderstorms are still possible north of the front, but it appears that there may be a strong temperature inversion developing there tonight, which could prevent the stronger wind gusts aloft from reaching the surface. But you need to remain alert even north of the front just in case.
The maps below show how my RPM model projects the timeline for these storms, and remember that you can follow all of tonight’s developing weather on the awesome radar display on the FREE Local4Casters weather app. Just search under WDIV in the app store.
Hopefully, the main line of storms will hold off until after the Tigers game. Don’t hesitate getting to your cars once the game ends (and check our app’s radar in between innings to see what’s going on).
Overnight lows will be crazy due to the front splitting our area. Those of you around and south of I-94 will likely remain in the low 60s (that’s 16° Celsius for our Canadian neighbors), while those of you north of M-59 will only be in the 40s (7° Celsius)!
While there may be some lingering showers first thing Tuesday morning, those should end rather quickly, leaving us with cloudy skies for the balance of the day. Again, it’s going to be a crazy temperature day: You folks that start the day south of the front in the warmer air will see temps drop through the day. Those of you north of the front starting your day already in the cooler air will see nearly steady temps all day long. The two temperature maps below show you the expected temperatures around the time you leave for work and come home later in the day.
Tuesday’s sunrise is at 6:35 AM, and Tuesday’s sunset is at 8:28 PM.
Gradual clearing Tuesday night, with lows in the upper 30s (4° Celsius).
Mostly sunny on Wednesday, with highs in the upper 50s to near 60° (15° Celsius).
Increasing clouds Wednesday night, with showers developing, late. Lows near 40° (4° Celsius).
Rain showers are likely on Thursday, with highs in the upper 50s to near 60° (15° Celsius).
Rain showers gradually diminish Thursday night, with lows near 40° (4° Celsius).
Partly cloudy on Friday, with highs in the low 60s (16° Celsius).
The upcoming weekend is a little tricky right now, but I expect Saturday to be the better of the two days, with partly cloudy skies and highs in the low 60s (16° Celsius).
There’s a chance of showers on Sunday, with highs in the upper 50s to near 60° (15° Celsius). However, I don’t have much confidence today in the computer models’ handling of the Sunday upper air pattern, so stay tuned -- this could change.
