000SXUS73 KGRR 282129RERMKGRECORD EVENT REPORTNATIONAL WEATHER SERVICE GRAND RAPIDS, MICHIGAN0525 PM EDT MON JUL 28 2025...RECORD HIGH TEMPERATURE SET AT MUSKEGON MI...A RECORD HIGH TEMPERATURE OF 91 DEGREES WAS SET AT MUSKEGON MI TODAY. THIS TIES THE OLD RECORD OF 91 DEGREES SET IN 1916 AND 1941.$$

Called it decades ago. Official response: deny, deny, downplay, inaction - "oh actually it is warming, but we can solve it by blocking out 5% of the sun." Oh, to top it off, we won't even bother telling the peasants! Wouldn't want the residents of Winnipeg, Yellow Knife or Fairbanks getting uppity about the loss of their precious sunlight.

Well, that doesn't bother me as much as lying or pretending it's not happening. Truthfully, I'm more vested in this from a scientific perspective than any political angle. I think you might have trouble convincing the residents of New Florida (i.e., the Upper Peninsula of Michigan) in 2400 AD/CE, that they were better off with 300" of snow each winter and subzero temperatures. Or the Megalopolis of Milwaukee, on the new North American Riviera, palm trees gently blowing in the breeze. Remember these places were under thousands of feet of glacial ice just 15,000 years ago! Oh, the irony of even having "Great Lakes" in a new hothouse earth. Carved from ice just 14,000 years ago. They shouldn't even exist in that paradigm!

It would be comical reading the Bastardi spin/delusion and obsession with highlighting a few cold areas, if it wasn't such a disservice to his followers. Anyways, in the real world, a top 10 hottest summer nationally is pretty much a lock, with another top 5 finish looking likely. And we are well within striking distance of making a run at the record hot summers on 1936 & 2021. But I'm sure the media will make it so we hear another 20 times about how it's a "record cold" summer in the San Francisco Bay area (it's actually not, lol).

With the ongoing heat, it wouldn't surprise me if the final tally comes in even higher. Climate Reanalyzer has 1936 & 2021 tied at +2.6F for JJA, followed by 2022 & 2024 at +2.5F. We should be around +2.4-2.5 for June & July. A hot August could get us to #1 - just imagine the meltdowns from some of these unhinged commenters on social media. The response to Tampa's all-time record high was just ridiculous. Imagine, a new national record.

JB posted this to X on Friday, so a little old. Only runs through the evening of the 23rd, but I don't have access to this real-time PRISM data - at least in a format that gives an estimated anomaly for the CONUS. At that time, we were running about 1.29F above the 1991-2020 mean, according to the PRISM analysis. Unfortunately, I'm having some trouble loading NCEI's Climate at a Glance this morning, so I don't have the exact numbers, but I think that would be close to 2.1F above the 1901-2000 average. So that would be around 10th/11th warmest July. Pretty much a statistical tie with the last two Julys.

Here were some NWS high temperatures reported yesterday in Central Florida. Clermont is a co-op with a 7 am observation time, so that 101F was from Saturday. It actually recorded a high of 103F yesterday [but which goes in the books for today]. Looks to be the highest official reading reported on xMacis. I did notice a few smaller airports around 102-104F in northern parts of the state. As you can see, the light northeasterly flow brought the coolest weather to the immediate east coast with mostly low 90s, but from Orlando west, upper 90s and some isolated 100F readings were common all the way to the Gulf coast.

Up to 10 days on the year now. Yesterday wound up warmer than expected but still fell 1F short. Next two days look like 90+, and Wednesday should be around 90 as well (depending on cloud cover and showers). Cooler and drier air pushes in on Thursday and lasts through the weekend. Highs over that stretch look like upper 70s to near 80. It doesn't look like anything crazy cold, but it should bring the longest sustained stretch of below normal temps since late May/beginning of June.

That’s the date that records began in Tampa, not the date of the prior record high.

All-time record high of 100F at Tampa:

I didn’t post anything about climate change. Posting observed temperatures and highlighting records from the recent heat wave is relevant weather related discussion. This is a weather board, no?

Why are you guys acting like this? I didn’t do anything to any of you. That is a FAKE graphic. Calling for me to banned for pointing that out? Like wtf?

Me? Are you joking? The context I provided about that chart is 100% correct. The claim that this is the “23rd lowest percentage of 90 degree days” is 100% made-up BS.

No, it’s not a legitimate trend. It doesn’t account for changing distribution of stations as I stated above. There are many more high elevation sites today that seldom or never reach 90F, so, of course the percentage of days at all sites will go down. That’s not even talking about the non-climatic biases that would have favored the older era. Maybe there were more, but that’s not the way to do that analysis.

See @bluewave and @donsutherland1 and others, he is a troll. This is the dumbest, most misleading graph produced by Tony Heller. It very well may be that there were a higher percentage of days in the Dust Bowl over 90F, but this graphic is a HOAX that is RIGGED to produce that result. It's always going to show that pattern. The distribution of stations has changed, favoring more high elevation and cooler microclimates that weren't represented much in the early decades. Moreover, time of observation changes result in an increase in 90F days, as there would often be additional days counted as a result of taking observations at 5pm or 6pm (e.g., day has high of 95F, at 5 pm, the thermometer is reset with the temperature reading 92F. The next afternoon reaches 84F, but the high is the observation temp of 92F). This is NOT an official NOAA/NCEI graphic, and NOT the right way to present climate data. Which is IRONIC since it originates from a loser (Tony Heller) who is always complaining about "corrupt" scientists. A legitimate analysis would at least make an effort at gridding the data to eliminate effects of a changing distribution of constituent stations and would apply an adjustment for non-climatic biases in the dataset. Of course, Tony never does this.

That's a misleading graphic. The distribution of stations has changed over time with more high elevation sites across the country than there were in the past. Moreover, most sites had afternoon/evening observation times before the 1960s-1990s, which results in somewhat of an overcount on metrics like these (e.g., day has high of 95F, at 5 pm, the observation temp is 92F... the next day's high is recorded as 92F, even if it might have only reached 84F).

Looks to stay pretty warm into early next week, but later in the week cooler air is set to infiltrate. August should begin on a mild note, but I would expect hotter weather to return at some point.

Currently at 8 days at or above 90F for the season at PIT. Looks like generally upper 80s to around 90 through Tuesday. We'll see if we can add some to that tally. Cooler air set to infiltrate late next week, with a milder start to August. I do expect another hot wave at some point in later August.

Widening out the view. A number of daily record high minima were observed yesterday at long term "threaded" sites... just looking her at places with 100-150+ years of record generally. There were certainly many more at cooperative observer sites and locations with shorter PORs. A number of locations saw low temperatures within 1 or 2F of record highs, and for those locations it was generally the 2nd or 3rd highest low for the date. Records: Rockford (74, tied) South Bend (74, tied) Huntington, WV (75) Paducah, KY (78) Meridian, MS (78) Jackson, MS (78, tied) Among maximum temperatures, not many records. Syracuse, New York set a new daily record of 94F. Several locations saw their 2nd or 3rd highest max temperature, but still fell well short of the record. We were competing with a 1934 heat episode that brought all-time record heat to some locations.

High temperatures yesterday across Southeast Lower Michigan. Reported highs ranged from 92 at Port Hope, Port Austin, Cass City and Linden, to 102F at Grosse Pointe Farms. The latter looks a little high, but I'm not sure of the microclimate there. The next closest (not shown) was 98F at Selfridge ANG Base. That site is on xMacis, but for some reason, the data doesn't get input until the end of the month. In fact, there are records for Mt. Clemens Area extending back to the 1800s. Weather Bureau sites, plus Uni. of Mich. (5 pm observation time) and White Lake 4 E (midnight to midnight - NWS office site): Other co-op sites, with morning observation times. Note that these go into the book as the temperatures for 7/25, but the highs occurred yesterday and the reported lows this morning:

Some much needed rainfall spreading into parts of northeastern Ohio. A number of locations have seen very little rainfall this month, with 0.18" at Burke Lakefront Airport, 0.21" at Akron Fulton International Airport, 0.50" at New Philadelphia Clever Field. Even the cooperative observer in Chardon has reported only 0.52" for the month, typically one of the wettest spots in northeast Ohio. Cleveland Hopkins International Airport and nearby Elyria - Lorain County Airport have picked up 0.79", while Ashtabula County Airport has seen 0.81".

A couple locations in far northern New York weren’t far from reaching record lows and record highs on consecutive days. Massena tied a record low of 47F yesterday, but fell 2F short of today’s record high. Plattsburgh missed a record low by 1F yesterday and missed a record high by 1F today.

Very impressive heat in southeast Lower Michigan today. Selfridge Air National Guard Base reached 98, its highest reading since 2012. 97 at Troy, Pontiac, and Ypsilanti (Willow Run). Flint and Coleman Young Airport topped out at 96. Detroit Metropolitan Wayne International Airport and Ann Arbor Municipal Airport both reached 95. Monroe reached 96, and even the traditional cool spot at Grosse Ile topped out at 95. Wonder what @michsnowfreak observed today? Looking at some backyard thermometers around Wyandotte, it looks like 97-98 was pretty common. Definitely a scorcher!
