Summer 2025 Banter Thread

[Chicago Storm]

[A-L-E-K]

Real?

 

[michsnowfreak]

Ive been looking into past heatwaves, primarily 1930s-1950s, and its insane to think how horrible it would be to live through that heat with no AC. The heatwaves were very deadly, and even many hospitals didnt have AC til the late 1940s or 1950s.

Zero tornado watches in eastern Iowa this year.

I'm in Chicago until 7/21, and I'm sure not loving this humidity. Any chance of a real cold front in the foreseeable future that will knock the DPs down to 50 or below??

Probably not until September.

Don't worry. Where we're going, the '30s-'50s dryland heat waves will look like a walk in the park. 2012 was the early warning shot.

(Take the following as an example of *what could happen*):

Ill believe it when I see it. Ive been hearing this for 2 decades now and still nothing close to rival those 1930s-50s heatwaves in terms of frequency, magnitude, and days in the 90s/100s here. In 2023 Detroit didnt eclipse 90° for the first time since 1915. Every single year in the aforementioned decades there was bad heat, some worse than others. Certainly some was dry, but not all.

But the ENTIRE point of my post was the fact that there was no AC. Ive been researching the daily newspapers and it wasnt just the occasional deadly heatwave. Each summer in those years had deadly heatwaves with the fatalities often listed in the papers. We know how bad tornadoes are for death, but in the pre-AC days the mere summer temperature was the most deadly aspect of the weather.

More development and solar farms should help us out of this mess /s

We've had not many MCS's making it east at all this summer, wonder if this might be the first summer without being affected by a derecho in years

The north-to-south temperature gradient has been too baggy.  Southern Canada warm, no big heat south.  Thus no jet dynamics to force convection and keep it going through the night.

We’ve had enough storm damage this year on this side of the state from the March 30 and May 15 events alone.  I’m not begging for a derecho here, but it seems without a better setup it’s hard to get even garden variety rains.

I think the biggest reason those records are so hard to beat is the increased humidity.  Modern agriculture with irrigation systems and a warmer GOM makes drought-driven heatwaves unlikely.  July 1995 showed you don’t always need low relative humidity to break records, but that was a much shorter event driven by an unusual synoptic pattern that was ultimately transient.  To get long-duration heat waves like the 1930s you need low RH.

105 dead in Texas with dozens missing still from the flooding. Horrific.

First we got rid of the clippers, now it looks like MCS are going extinct as well lol

Hoping for some rain today. Tomorrow will mark 21 days since the last meaningful drop of rain for my house. Wednesday June 23rd we had some good rain and nothing but showers off in the distance since

I dont disagree. My point was that we aren't seeing those high temps be matched or exceeded anytime soon.

Looking like another whiff. No rain and pretty much every day in the 90s for three weeks straight. Excited for our next dust storm warning.

I don't know how this myth keeps coming up. Recent summers have been hotter and more humid at Detroit. This is objective data, not opinion. Note data discontinuity in 1959 is responsible for much of the cooling in the 1960s and 1970s. Data for 1934-1958 from City Airport, and from Metropolitan Wayne International Airport since 1959. Data source for all hourly readings is Iowa Environmental Mesonet, and for the mean average temperatures is xMacis.

Wish they kept the same observation site since 1934
