Just came to edit my post but you beat me to it lol. The 86゚ dewpoint was Marshall. I am not familiar with that station so I cannot say, but I am familiar with Monroe. There was one day I think a week ago or so that Monroe had dewpoints touching 80 when every other station was below 70. To be honest I kept checking the Monroe dewpoint yesterday just to see how high it would go lol, knowing it is not correct, and I expected higher than its peak of 85゚. The highest "official" dewpoints at the nearest first order stations to Monroe were 78° at Toledo and 77° Detroit. Still, I have a very hard time believing that Marshall dewpoint. Whenever a station is many degrees higher than anywhere surrounding it, it's a red flag. The closest stations to Marshall- Battle Creek Kellogg, Battle Creek/Kalamazoo, and Jackson, had peak dewpoints of 79, 80, and 79.
