Detroit Golf Club gets four days in with almost no wind, highs climbing toward 90, and a rain threat that has shrunk with every update. Saturday is still the possible wet day, but it is no longer the washout it looked like on Monday.
The models agree with each other more than they usually do at this range. Sunny and dry Thursday, hot and still Friday, unsettled air arriving Saturday. Where they split is Sunday timing, whether the showers land on the early groups or drag into the afternoon.
Thursday: Round 1 Weather
Thursday, July 30 is the cleanest scoring day on the board. Full sun, a high near 89, and a north breeze that tops out around 10 mph with gusts to 16 early before it settles down. Rain chances near zero.

Friday: Round 2 Weather
Friday morning may be the calmest six hours of golf of the week. Wind runs 1 to 4 mph with gusts of 4, which is not really wind, under heavy cloud and building heat that peaks at 90 in the afternoon. The shower risk that looked like a problem earlier in the week has faded to 11 percent, so the second round is the softest test of the four.

Saturday: Round 3 Weather
Saturday, August 1 is the only day that can genuinely reshape this tournament, and even it has been backing off. Rain risk climbs from 18 percent in the morning to 39 percent for the late groups under a completely grey sky, with the heat holding at 88 and humidity that makes it feel worse than the number reads. Wind stays beside the point, gusting no higher than 13 out of the east-southeast.

Sunday: Final Round Weather
Sunday is damp at both ends and still not windy. The early groups head out into a 27 percent rain chance and a grey sky, then the clouds break for the closing stretch even as the shower risk ticks back up to 32 percent. A high of 86 with a feels-like near 90 makes the finish the muggiest stretch of the week.

Betting and DFS Outlook
Wind is not really going to be a factor this week in Motown. The strongest gust anywhere in the four-day forecast is 16 mph on Thursday morning, and Friday’s morning wave gets gusts of 4.
What is left is moisture. Saturday and Sunday both carry real rain chances; the greens were going to hold anyway, and that points the scoring defense toward length off the tee and wedge play into receptive targets rather than scrambling. The wave edge barely exists, though the Friday morning draw is the single calmest window on the board if you want one. The item actually worth pricing is delay risk on Saturday afternoon, which can bunch tee times and shove part of the third round into Sunday morning. But that’s impossible to really guess at, and you’d be throwing darts blindfolded.
