Metro Detroit weather forecast: Cooler temps ahead?

Paul Gross breaks down rainfall totals


DETROIT – Monday night’s rainfall came in pretty much as expected, and all of us got a good soaking. I think we can safely say that we’ve put a pretty good dent into our drought conditions, although some of us have definitely received more rain than others.

Here are the top five rainfall totals from last night’s event, as well as how much total rain we’ve had since late last week:


Now that we have a lot of standing water and wet ground, this, combined with at least partial clearing and very light wind overnight, has us primed for some fog development after midnight. If you’ll be up and out early Wednesday, be aware that this could be dense fog in some areas. Lows will be in the mid to upper 60s (that’s 19 degrees Celsius for our Canadian neighbors).

Once the early morning fog dissipates on Wednesday, expect partly cloudy skies. Then an approaching surface trough (sort of a cold front that didn’t graduate from cold front school) will trigger some scattered afternoon showers and thunderstorms. Some of us won’t get a drop, but be aware that some will.

Highs Wednesday will be in the mid 80s (29 degrees Celsius). Winds will be southwest at 5 to 10 mph.

Wednesday’s sunrise is at 6:43 a.m. and Wednesday’s sunset is at 8:30 p.m.

It will become partly cloudy Wednesday night with some late-night fog still possible. Lows will be in the mid to upper 60s (19 degrees Celsius).

Thursday will be partly cloudy with only the very slight chance for an isolated pop-up afternoon thunderstorm. Highs will be in the mid to upper 80s (30 degrees Celsius).

Thursday night will be mostly clear with lows near 70 degrees (20 degrees Celsius).

It will be partly cloudy on Friday with highs in the upper 80s (31 degrees Celsius).

Friday night will be mostly clear  with lows in the low 70s (21 degrees Celsius).

Alright, let’s now talk about the weekend cold front.

Tuesday's models are handling its speed differently than they did Monday, because they are suggesting a deeper-than-expected upper level trough of low pressure, which is slowing things down. What this means is that we may get through the majority of Saturday’s daytime hours without a thunderstorm. But you still need to monitor for a late-afternoon storm.

Highs appear to be in the mid to upper 80s (30-31 degrees Celsius) depending upon how much cloud cover we have.

There’s a better chance for showers and storms Saturday night, with lows in the low 70s (21 degrees Celsius).

Showers and thunderstorms will probably start our day on Sunday, but should end by late morning, with skies becoming partly cloudy during the afternoon. Highs will be near 80 degrees (27 degrees Celsius).

Then get ready for a stretch of spectacular -- truly gorgeous -- late summer weather. Expect partly cloudy to mostly sunny skies Monday through Thursday, with highs ranging from the mid 70s (24-25 degrees Celsius) on Monday to the low 80s (28 degrees by Thursday).

Overnight lows should range from the upper 50s to low 60s (14-16 degrees Celsius). Best of all, humidity should be low.
