  1. Wow, in a stunning reversal from the high heat and humidity, Saranac Lake dropped to 34F, tying its daily record low set in 1914. The all-time record July monthly record low in the Saranac Lake threaded record is 29F, set on July 8, 1919. At the airport site, the all-time record low is 32F, which has been set on more than one day, last on July 28, 2001. The all-time observed record low for the month of July in the state of New York is 25F, which was set at Allegany State Park, in Cattaragus County, on July 8, 1963. Edited to remove the reference to Millbrook... I assumed that was a CRN site since xMacis labels it a "WBAN" station and not a "COOP" but it isn't and the temperature data for yesterday appears to be incorrect there. It obviously wasn't 87/32 there yesterday. Lol.
  2. Upper 50s looking likely tonight. Brief cooldown with heat returning on Wednesday. 8” of Reddit rain nowhere to be found.
  3. Wow, that is insane! Is that an 83F dewpoint? Wtf? That is a wet bulb of 85F or 86F, not this WBGT meme, but bona fide wet bulb. A wet bulb of 95F (35C) is deadly if you are out in it for any extended period of time (even inactive and in the shade), maybe even somewhat cooler than that. Definitely take proper precautions in those conditions.
  4. With how much rain there's been of late, I'd say that's a good thing. I hope it continues weakening. Doesn't look like a big rainmaker at this point in any event, although there are still some areas of embedded heavier downpours where I guess a quarter to half inch could fall.
  5. See this kind of rhetoric is unnecessary. The NCEI trend for Southeast Lower Michigan is in close agreement with the Ann Arbor and Detroit data, with the exception that the mean temperature is somewhat below those sites (since the district as a whole is somewhat closer), even without any adjustments for discontinuities (location change) or changes in equipment or time of observations. Maybe a case could be made that the January trend is a little inflated, but all of these sites still show warming in January. And for the annual change, it's quite close to NCEI's numbers. It should be noted that there is NO time of observation bias in the Ann Arbor data - unlike most cooperative observers, they have maintained a consistent evening observation time. Of course, there's none in the Detroit data either (consistent midnight-midnight day, per Weather Bureau standards), but there are a couple of important site changes.
  6. Heck, it aligns almost perfectly with the Detroit threaded record. A touch colder in the early decades, but not surprising considering given the siting/location of the Detroit City record in that era. In recent years, it has shown somewhat less warming, although the broad trends align VERY closely.
  7. I don't CHERRY PICK anything. I also am not opposed to using raw data to show broad trends, but it's important to be mindful of the possible biases in the data being presented. How is noting a bias in the data being biased? As far as any problem with the Ann Arbor data, I'm not seeing it. It's right in line with the rest of southern Michigan for data from the late 1880s - 1890s period, which is freely accessible from NCEI.
  8. I think the biggest surprise for me was how few 70F+ dewpoints there were in 2016 despite that being a scorching summer (hottest on record at Detroit). Only 9 hours at this point at Detroit, and 1 hour at Pittsburgh. Also, somewhat surprising, through yesterday's date, 2016 was 1F cooler than this summer to date at Detroit. It's been 10 years so my memory is getting a little fuzzy, but it must have been an all out torch from here on out that year.
  9. Saw a post from the Southeast Regional Climate Center about 70F dewpoint hours and decided to take a look in the Great Lakes region, and WOW. Record hours of 70F dewpoints pretty much across the board. Nuts.
  10. The dew lovers must really be liking these trends. Eventually may just be wall to wall 70F dewpoints all summer long?
  11. Here's how Boston is doing for hourly observations with a dewpoint at or above 70F for the season to date: Currently, in 4th place behind 2024, 2013 and 1984, with 188 hours. I wonder how many 70F dewpoint hours have been lost this summer due to some of the ASOS issues? In 2004 & 1951, there were 0 hours with a dewpoint at or above 70F at his point in the season.
  12. Here is Pittsburgh for the summer to date. Wow! Second only to 2005, with 253 hours with a dewpoint at or above 70F so far this season. The average is a hair under 50 hours, although the average is clearly pushed up by anomalously humid years like this one, 2005 & 1949. The median is clearly below the arithmetic mean. By contrast, there were no 70F dewpoints in 1960, 1967, 1975, 1971 or 1976 by this point in the summer. More recently, only 1 hour of 70F+ dewpoints had been observed at this point in 2016 (kind of surprising, as that was a fairly hot summer) and only 3 hours in 2023.
  13. Got this idea from the SERCC X/Twitter account (see post below)
  14. For a more evidence-based analysis, NCEI shows January has warmed at a rate of about 2F/century on average in the whole of Southeast Michigan. Why the divergence between your numbers? None of them, except the Ann Arbor data is from a single site. According to your analysis (I didn't independently verify), the Ann Arbor data is exactly flat over the last 100 years. But reviewing the data, the time of observation moves from 5 pm to early morning. There is also a bias from the switch to MMTS, both of which are corrected in the NCEI data. The other sites are all amalgamations of distinct stations. Toledo and Detroit go from rooftop stations in downtown [and, in the case of Toledo, very near Lake Erie, which has a warming influence in the winter] to suburban (DTW) or even downright rural (TOL) airport locations, with proper siting on the ground.
  15. You are something else. I love how you always do what you accuse me and @bluewaveof doing. Let me try to understand this: Co-op data good when it shows less warming, co-op data bad when it shows more warming? Am I doing this right? And you always claim I ignore data I don't like but are CONSTANTLY doing the same: "The data is suspiciously cold." My man, this is data collected by the University of Michigan. At least the older data collection was probably handled by the earth sciences department. Are you saying the University of Michigan doesn't/didn't know how to properly collect temperatures and precipitation? It's funny because if I doubt an old record high temperature that's way out of line with surrounding observations, you accuse me of doing this. Now, you are out here complaining about old temperature records from a top public research university. In the hierarchy of things, I always give the most weight to records collected by the Weather Bureau/NWS at first-order sites, followed by universities, experimental farms and state/national forests and parks, since these are the sites that were manned by meteorologists, agronomists, or park rangers [i.e., people with an earth science background]. You also like to go on about cherrypicking start dates (1960s & 70s). I like to use these as a baseline since the data is more consistent [i.e., fewer station moves and less biases] and more relevant to current trends. But you say its cherrypicking. But now, you throw out the observations from the 1800s because you don't like the trend, and insist on showing the trend from 1920s? How is that not considered cherrypicking? Warming since 1880, significant warming since 1960/1970 - oh, but we must only consider the trend from exactly the 1920s, where there is little warming?
  16. Additionally, a number of locations were within a degree or two of record high minimum temperatures. If not for the scattered convection, there probably would have been more records. Rain seems more effective at cooling than nighttime in 2025.
  17. Wow, looks like 95F at Portsmouth, New Hampshire. Some of the highest temperatures observed during the recent heat wave in New England:
  18. Has anyone heard anything about tropical remnants coming next week? I saw a post on Reddit talking about some models showing up to 8 inches of rain from Invest 93L?
  19. Just knew we were due for a good rain bomb.
  20. All I'm saying is the normal is 1F higher than the mean (which I explicitly demonstrated above by comparing the two). Why? I don't know. Doesn't seem to be the case anywhere else, so that's why I was speculating it may be piloting a new method of calculating normals to factor in warming climate. Other than that, I have no more to offer on the topic.
  21. I'm saying the normal was raised by that amount above and beyond what the mean of the 30-year average was observed to be. Not that the normal was increased by that amount relative to 1981-2010. It increased by the amount of the observed increase, plus an extra degree or two at those locations. Other stations also had smaller extra bumps. I don't think this was done elsewhere. Generally, the normals line up with the calculated mean.
  22. I just posted two examples above, where the normal is 1F and 1.9F above the 1991-2020 mean.
  23. You can see this phenomenon in the 1991-2020 normals for Cleveland and Toledo. You can see they tack on an extra ~1F to every month at Cleveland and extra ~2F to every month at Toledo. Must be some sort of program they are planning on rolling out nationwide with the 2001-2030 normals. I guess they think if they just jack up what is normal, people won't notice how abnormal it is? If that was the goal, it doesn't seem to be working too well - as it is still almost always above normal at those locations, just not by as much as other locations nearby.
