July 2025 General Discussion

[Torchageddon]

This is a torrid day, I was out at 8am walking for a few mins and I was yet hot. Among the most humid mornings of 2025. By 11 it was already 31 hum of 39. Point of 32C - I add 3C to whatever value so I may have a 35C/95F day coming up. Strong storms fore by eve. Body temperature rising

Not even scraps make it here, but of course just enough outflow debris to prevent any action this afternoon.

DP in the 40s but can’t go outside because AQI in the 180s.

Wow those are some low dews for July.

Looking like a break from the 70 degree dews here for tomorrow.  Looks like dews should mix down to near 60 in the afternoon, which is great for the corn belt in mid July.

Looking further ahead 80 degree dews are coming the week after next from the looks of things.

Went to the Tigers game last night. Humidity was just oppressive. Temp was 82 with a dew of 73. Not comfortable at all. And it really shows the difference between slightly humid and huuuuumid.

Another of meteorological summer, another month of relentless rain for 2025 (especially some days of biblical rainfall)

In between the "relentless rains," Dayton has done quite well with heat. Today was the 11th 90F+ reading of the season. Dating back to 1955 (71 years), that amount has only been exceeded through today's date (July 12) in 5 years (1966, 1988, 1994, 2012, and 2020).

Through yesterday, the mean temperature was 6th highest in the threaded record. A little weird that they use the warmer, low elevation Miami Conservancy District building records for 1943 & 1944, instead of the higher elevation airport site.

At the airport site, it has been the warmest since 1935, outpacing both of those years. Today's heat should help these numbers somewhat. The forecast calls for generally warm and summery weather conditions over the next several days, with highs forecast in the upper 80s tomorrow & Monday, near 90 on Tuesday and Wednesday, upper 80s Thursday, and perhaps cooling to the middle 80s by Friday.

Hot one today in the Eastern Lakes. The high reached 93 degrees at Erie, 1 degree shy of the record set in 2005 & 1936. Cleveland officially topped off at 92 degrees, 2 shy of the record set in 1936. However, it reached 95 degrees at Burke Lakefront Airport. May have been a record if the official station was downtown as in 1936. A stout southerly, downsloping flow brought some of the warmest temperatures to the lakefront. Certainly, not cooler by the lake today!

Could be a little smoky around Chicago tomorrow.  A pretty good batch of smoke over the Twin Cities currently, with visibilities down to as low as 3 miles at MSP. PurpleAir gauges are showing AQI generally in the 150-200 range. Should push east tomorrow, but could make its way into northern Illinois per the HRRR.

On Monday, another plume of smoke reaches the Twin Cities with degraded air quality and visibility restrictions. The initial batch settles over Michigan. While total smoke particulate quantities aren't super high, the smoke that will be present will be trapped near the surface. So it should be a hazy day with somewhat degraded air quality around Detroit, Toledo and Grand Rapids.

Speaking of Cleveland, yesterday was the 21st straight day with a low temp at or above 65, setting a new record.  Will be interesting to see how long they can stretch this as there are no lows below 65 in the forecast for the next 7 days.

Wow, very impressive. All of the higher streaks of my graphic are from downtown. Up to 22 days now. Today will certainly bring this up to 23 days, and the current forecast would suggest it reaches at least 29 days.

These climate posts suck so bad

[Brian D]

Smoky day yesterday, and last night. Smell got real bad last night. Still here this morning, but thinning out until the next batch. 

[OrdIowPitMsp]

Smoke quickly exiting the area with a SW flow. AQI down from 185 to 101

[luckyweather]

was in Lake Geneva today, sky is milky white with the wildfire smoke, hints of burning plastic outside. bleh

[Torchageddon]

I knew there was a high aqi, saw the milk sky too but wanted to cycle. As soon as I stepped foot out there, my sniffer catching the stench of rank plastic and ash, I nope'd and turned right back inside. First this year and 3rd time in my life I surrendered to air.

I had my bedroom window open last night and woke up hacking.  I get more sensitive to this crap as I get older.

Yesterday marked the beginning of an upcoming stretch of relentless rains. The next 1-2 weeks are looking to be a wash. Shades of July '92.

Today's 12z Euro run doesn't show any dry days at all until July 26th. 

Beyond the 10-day, TWC/WUnderground has rain and storms all the way through at least the 28th of this month. Brutal.


NWS doesn't have any dry days in sight through next weekend.
