Metro Detroit weather: Relief from humidity ahead

Paul Gross announces exciting end to golf quest

DETROIT – So here we are, in the first week of September, and we have some of the highest humidity of the entire summer. Relief from the humidity will come in stages over the next couple of days, so stay patient. Great sleeping weather is right around the corner.

Any scattered, light, lingering showers late Thursday afternoon should end during the evening, with skies clearing after that. However, I think we’ll see a pretty solid blanket of fog developing across the area, so be aware of this possibility if you’ll be out late Thursday or early Friday morning. Lows will be in the mid-60s, or 18 degrees Celsius for our Canadian neighbors. Light southwest winds will shift to the northwest after a modest cold front crosses the area.

Early morning fog should dissipate by late Friday morning, and we should be mostly sunny by lunchtime, although clouds will increase by late afternoon. I am somewhat concerned about a stout temperature inversion I’m seeing in tomorrow’s forecast upper air soundings. Those inversions sometimes trap fog and clouds and keep them around, but I think it’s still early enough in the meteorological fall season to give us enough heating in the morning to lift the fog layer and allow it to dissipate.

Highs will be in the low 80s (28 degrees Celsius) with a northwest wind shifting to the southeast at three to seven mph.  You’ll also notice less humidity Friday. It’s still going to be humid, but not as oppressively steamy as it has been Wednesday and Thursday.

As long as that temperature inversion doesn’t mess things up Friday, it’ll be a splendid day for me to play my "Twelfth Consecutive Month of Michigan Golf." As I’ve been telling you, last summer, when I saw that strong El Nino developing and knew it would be a warm winter, I started my quest to play at least nine holes of golf for twelve consecutive months, which is quite a challenge here in the Great White North, where it snows every winter.

I’ve played every month since last October, which makes this month the completion of my quest. I’m going out in style, big time. I have been extended a gracious invitation to play a special round on the historic South Course at Oakland Hills Country Club. The South Course was designed by renowned golf course architect Donald Ross and opened in 1918.

Since that time, the course has hosted sixteen major championships, including six U.S. Opens, the 90th PGA Championship, and the 2004 Ryder Cup.

As you know, I am a huge history buff, and you can imagine what will be going through my mind as I walk down those historic fairways in the footsteps of golf’s all-time greats. Joining me for the round will be Oakland Hills member Ted Stacy, Ken Kal (Detroit Red Wings radio play-by-play announcer), and longtime friend Dave Riger (producer of Glen Haege’s "Ask the Handyman" show on WJR). It’s going to be a very special day.

Alright, back to the forecast.

Rain will develop Friday night -- hopefully after the high school football games -- with lows near 70 degrees (21 degrees Celsius), as the humidity ramps right back up. But don’t worry, it’s temporary.

Saturday means college football, including Michigan’s home game at noon. While the weather pattern is still a little murky, enough of it is coming into focus where I can try to get specific to help you plan your day.

We’ll likely start Saturday with some showers in the area, and then I think we may see a break from the rain for the late morning and early afternoon hours, which is important for tailgaters. However, a potent cold front will cross the area during the afternoon (probably mid-to-late afternoon), with a line of thunderstorms that could potentially be strong to severe. It all depends on the front’s timing. If it's later, that means the atmosphere will warm up more and becomes more unstable, while earlier is the opposite.

If you have outdoor plans (football or not), I strongly urge you to monitor the radar on the free Local4Casters app. If you don’t have the app, just search under WDIV in the app store.

Highs Saturday should reach the upper 70s to near 80 degrees (26-27 degrees Celsius). It’ll still be quite humid. Once the cold front clears the area, not only will it take the rain and storms with it and lower our humidity, it’ll also ramp up the wind, which will continue into Saturday evening from the west at around 20-25 mph.

Clearing will commence Saturday night, with lows in the mid-50s (12-13 degrees Celsius).

Sunday will be mostly sunny to partly cloudy, and you’ll definitely notice the air mass change, with highs in the low to mid-70s (23 degrees Celsius). It will be mostly clear Sunday night with lows in the low to mid-50s (11-12 degrees Celsius).

It will be mostly sunny on Monday -- a splendid day -- with highs in the mid-70s (25 degrees Celsius). Monday night will be mostly clear, with lows in the upper 50s (15 degrees Celsius).

It will be partly cloudy on Tuesday, with a chance for some showers and thunderstorms later in the day as another cold front approaches. Highs will be near 80 degrees (26 degrees Celsius).

Showers and thunderstorms are likely for part of Tuesday night, with lows in the mid-50s (14 degrees Celsius).

Wednesday will be partly cloudy, breezy and cooler with highs in the low 70s (22 degrees Celsius).

Thursday and Friday look terrific, with mostly sunny or partly cloudy skies and highs in the mid-70s (25 degrees Celsius).
