Upon further analysis - apparently it wasnt as extreme as I thought. The nighttime lows really did the lifting from late June thru July, but not the entire summer. June High/Low: +2.3F / +2.1F July High/Low: +1.2F / +2.6F August High/Low: -0.9F / -1.4F December High/Low: +1.8F / +2.2F January High/Low: -2.4F / -3.0F February High/Low: -2.4F / -1.4F

Very interesting...here its BY FAR most noticeable in summer. Winter mins still tank on clear nights. The only thing that holds them up is an overcast Great Lakes night, often accompanied by snow showers, while west of Lake MI will be clear and cold. Theres no comparison between summer and winter mins.

My friend in Long Island said it was the most comfortable August he could remember. Here, the last week of August saw the traditional cold spots of SE MI dip into the upper 30s to low 40s. I dont care that they are the usual cold spots...its very impressive to have that on multiple nights in August. This is August 30th:

Detroit tied with 2 other years for 7th most days with mins of 70°+ (24) but tied with 10 other years for 44th most days of 90°+ (14). You can see it was the nights that did the lifting.

Im seeing double

Agree. Summers unbearable humidity was basically condensed into a 2 month stretch from approximately June 20 - August 20 or so. With a break in early August. It was way more muggy nights than hot days. There were 14 days of 90+ at DTW, which is 1 more than normal, and a max of 95.

We didnt see extreme high temps here, but the warm muggy nights were placing the summer higher into the hottest summers list, but the last week of August was the 7th coldest on record for Detroit, plummeting the summer out of the top 20 hottest.

Ive been saying since April 2014, we will never see another 2013-14 again in our lifetimes, referring to sensible weather. It wasnt just the snowiest winter on record. The combo of snow + cold + snow depth + wind had never been seen in the record era, and not even close.

Last week of August was 7th coldest on record at Detroit which plummeted the hot summer ranking out of the top 20.

Not only have there been numerous days in the 40s in most areas but there have also been several in the upper 30s in the traditional cold spots of SE MI. Very impressive for August. This mornings low of 50 was a bit suspicious at DTW. It is the 4th low of 50 this week but today was the coldest morning. Every other nearby station was well in the 40s, including thermometers near the airport. I haven't noticed any discrepancies in DTW temps lately, so hopefully its just an unfortunate one off. Other lows this morning included 44 at Ypsilanti (right outside DTW), 43 in Monroe, 39 in White Lake and 38 in Ann Arbor. Even Detroit City was 47 for their coldest Aug temp since 1986 (you know the DTW number is suspicious when nearby YIP is 6° colder and even DET is 3° colder).

Its already been dry here in August. But honestly I dont care. As long as it gets more active in winter im fine. Definitely want to avoid any late heat. I am amazed how the color is picking up so early. The last week, Detroit has now had a low of 58, 55, 50, 50, 53, 50 with most suburbs in the 40s multiple times including several around 40 in the traditional cold spots. The forecast low tonight is 48 Detroit with 40s everywhere else, then some 50s, and the more 40s later in the week. With low humidity, sunny days, and 2+ consecutive weeks of cooler than normal nights, the color will continue to expand.

I remember. Don't think we see that kind of heat later in September this year though.

I also have a feeling the trees are really going to start taking off with these cool nights. Its not at all uncommon to see some stressed color by now, but I've been noticing many trees starting to get some color the last few days.

We had a 100% chance of rain today and I didnt see a drop

After a warm, humid summer where the persistant warm, humid nights, not extreme hot days, were what made their mark....We are now in a stretch of a what will be about 10 days straight of unseasonably cool nights, several of them flirting in record low territory, so to say that summers back is broken is an understatement. The trees are starting to get some color as well.
