Looking at the Michigan roundup from yesterday, a number of locations saw temperatures climb at or above 90F, including as hot as 92F at Auburn 2NE. Unfortunately, the urban chill island of Detroit could only muster a disappointing 86F. Going to be another one of those summers, where @michsnowfreak is bragging about the lack of 90F heat, whilst complaining about urban heat islands, all the while rural areas where nobody lives rack up plenty of 90s. In order for Detroit to record some readings in the 90s, it looks like some rural parts of the State will need to reach well into the mid 90s, even upper 90s. Maybe a tall ask.

Its going to be another one of those summers (and falls and winters and springs) where @TheClimateChanger spends hours and hours scouring xmacis and ncdc to find the most random, middle-of-nowhere location that he can plug into his latest cherry picked post.

Its crazy, Ive lived in MI my entire life and I always thought Alpena, Standish, Saginaw etc were hours away from Detroit. But apparently, they are rural suburbs of Detroit . The actual metro-Detroit suburb temps for that day were all in the same range, 84, 85, 86, 87. The warmest temp found was 88F at White Lake, 40+ miles NW of DTW. I just want accurate readings- readings in line with nearby areas. But I guess you want the official station to come in 2-4F warmer than everywhere else.

Picked up a total of 1.20" rain yesterday, 0.58" of which came from the evening shelf cloud thunderstorm. Definitely the best thunderstorm we have had in a long while. I saw some incredible pics from more open areas, but i was at home so wasn't able to see the cloud expand over an open area in all its glory.

63, cloudy and a NW breeze at 1pm. Hard to believe whats lurking.

You should be very pleased with my Michigan round-up then! You are the one who has thrown out comparisons to White Lake, Flint, Saginaw, and Ann Arbor in the past - all of which were warmer than DTW in my summary, some by several degrees.

Good thing I just bought new tires yesterday. I was trying to get in front of a small cell in front of the main line of storms that was rotating and had a nice wall cloud on it when the gust front from the line caught me from behind.  I mean wind went from 0 to 70 or 80 in a flash. This damn tree came down about 50 yards in front of me as I was going about 45mph. I think my old 10 year old tires would've probably killed me lol. Lots of really big trees, limbs, fences, sheds some roofs and barns blown down between Lapel and Muncie. Really strong microburst downdraft through that area as the trees weren't "blowing" sideways it was the wind blowing the trees actually down towards the ground. You could feel the wind coming down like a hammer. Temp went from 85 to 66 in about 90 seconds. One of the weirdest things I've ever been caught in.  I drove home and put my underwear in the washer 

Got up this morning and we got another 3 in and its still raining. This area is flooded pretty bad.

 

Wow, you're really getting killed by the rain. We had 1.31" yesterday/this morning.  We also had a downburst. Lots of trees and powerlines down in about 1 x 4 mile area. I purposely drove into it as I close to it when I saw it on the velocity scan. A tree came down across the road I was on about a minute after I passed it. Here is part of my dashcam video. The first part is the shelf cloud (sped up slightly) and the last part is driving into it. No audio at first and the last couple minutes is me driving into the abyss, to which the video doesn't do justice. Most of the time, I could only go about 10 MPH.

This is exactly what I and others mean about cherry picking. You are picking one random day where temps were 1-2F warmer at those locations than Detroit. I can assure you it wasnt close to 90F here the other day. Everyone in THIS immediate area maxed at 85 or 86. Detroits annual temp runs about 0.5-1F warmer than Ann Arbor, 2-2.5F warmer than Flint/Saginaw, and 3.5-4F warmer than White Lake. It does not mean there wont be days where DTW is cooler than the others. 

But my point stands. If DTW (or any site really) temps are in line with all other locations in the immediate area, I have no issue. My issue is when one random site runs 2-4F warmer than anyone else nearby with no clear reason it should (ie marine influence would be an example of an exception). Thats why the NWS ensures first order sites are properly maintained and calibrated. Its no secret that you WANT sites to run falsely warm, so when they dont, you resort to posts like this.

I'm not cherrypicking anything. Just looking to learn more about the DTW urban heat island. Those temperature variances strike me as primarily a function of elevation and latitude. Urban heat island may add a small component. White Lake is several hundred feet higher in elevation and, as you said, 40 miles northwest. FNT and MBS are way to the north, and FNT is also a few hundred feet higher in elevation. Even Ann Arbor gains elevation, although it might be small if along Allen Creek. Of course, if the station is near the creek, it would likely be in a particularly cool microclimate for radiational cooling conditions.
