You are yet to point out any bias in my posts. I agree with you that everyone doesn’t care about the warming. But if you want to make a decent forecast of any kind, then you need to understand how these significant and frequent baseline temperature jumps have been influencing the sensible winter weather. Since the sensible weather at any given global climate era in Earths long history has been a function of the baseline temperature regimes of those eras. You mention bullying. But it’s Ironic that you have used the most harsh language and displayed an angry demeanor with anyone that disagrees with you on these forums. I respectfully disagree with some posts and provide data as to my thinking. All you seem to do is hurl insults. What you call lecturing is a discussion of the actual weather we have been experiencing. But I will chalk this up to not actually meeting in person and perhaps is a bit of a keyboard warrior schtick on your part. I would bet we could have some more civil conversations if I met you at one of the conferences. Since sometimes people get the wrong idea without actually meeting in person. As to last winter, I was anticipating the mismatch as early as last October. So the NYC temperatures verified to the warm side of past mismatch instances. But I pointed this out this in my early season analysis. The winter average temperature in NYC this past season was close to the average before the baseline jumps of recent decades. So it wasn’t anywhere near as cold as some of the great winters were prior to the baseline jump in 15-16.

Yeah, but it also goes beyond the opposite SST pattern in 13-14 to what we have today. That winter was also the function of a colder climate era before the big baseline temperature jumps in 15-16 and 23-24. So even a complete reversal of the Pacific pattern at some point in the future probably wouldn’t yield an outcome as cold or snowy. Plus the Northern Hemisphere cold pool during the winters have become so small, that the 500mb ridges would be more expansive and troughs smaller than 13-14. We would need a major volcanic eruption to ever see a repeat of winters like 1975-1976, 1995-1996, 2009-2010, 2010-2011, 2013-2014, and 2014-2015. This is why I don’t like using those analogs since they were products of much colder background states. Last December I didn’t think that some talk of a 2013-2014 ABNA style pattern repeating would be supported by this warmer climate. This turned out to be correct.

I posted it for the general continuing theme of at least some stations experiencing measurable rainfall on the weekends. They haven’t done an official update yet so that is their most recent chart showing the long term pattern in general across the region. If the smaller local was included, then it would show the continuation. A few spots picked some measurable rainfall that weekend along with more last weekend. But the amounts were very light indicating no washout. Data for July 5, 2025 through July 6, 2025 Click column heading to sort ascending, click again to sort descending.

The best beach days continue to be during the week. The next 95°-100° warm up looks like it will be Thursday and Friday with more rain chances again next weekend. But the one good thing is that there have been very few weekend washouts.

You seem to have a very selective memory when it comes to posts and discussions in these various threads. What usually happens is that I discuss a forecast and pattern and add perspective to my post. I discuss how the individual forecast period or pattern relates to the greater pattern on the whole. Including weather history in the post adds an extra dimension which helps to explain and bring the pattern to life for the reader. But you and some other posters will frequently respond with a post like your local area is different and it isn’t warming like the other areas are. Then I dig into the weather history for your local area and show that the pattern and trend is pretty much the same as other areas are. It’s you and other posters trying to claim that you live in an area which somehow seems to be defying the rest of the world’s trends or that it’s all just UHI. If you didn’t try to claim that your area is somehow different from the other areas that I am discussing, then these threads wouldn’t keep going off topic. Since local weather and climate patterns are driven by broader global ones. It isn’t fair that you are trying to shut down a discussion that stems from a comment that you made. Look, I get it that some people don’t enjoy the fact that the earth is warming. So it’s a natural defense mechanism to not acknowledge it. But this narrow perspective is incomplete and leads to less reliable forecasts based on climate states and patterns which no longer exist. The other issue is that some posters view weather and climate through a political prism. This inevitably leads to a distorted perspective since a political belief is separate from issues dealing with the natural world like weather and climate. You will notice that I never bring up politics or policy perspectives. This is due to the fact that I am not really a political person. So you have to understand that recognizing the fact that the world is warming and it’s affecting our sensible weather on many levels doesn’t mean that I am advocating for any specific policies or programs. Since it’s up to each individual what types of policies they they want which is outside the scope of these threads.

The WAA actually peaked around 8-10 pm for the day with +20°C 850s arriving late. So we got that combined with downsloping and drying. It allowed the earlier low max at ISP to hold at 79°. That was the 3rd warmest low max ever at ISP.

Looks like a strong sea breeze especially South Shore. The 95°-100° heat potential later next week will probably be focused more in NJ. This doesn’t look as widespread or as warm as the late June record 100° to 105° warmth. So especially for spots like JFK, the late June heatwave will remain the strongest of the summer so far.

It’s good that they have a continuous record at Ann Arbor since it shows a similar long term trend is Wayne County. The NCDC takes into account station moves like Detroit compared to the rest of the county. As you said, January has seen the slowest warming since 1895. But December and February have warmed at a faster pace. This makes sense since the falls have also been warming. So it takes longer for winter to get started and the winters across the U.S. are getting shorter with more warming in February. December +4.3°/Century January +2.0°F/Century February +5.1°F/Century

We have only had one October really amplified MJO 5-6 during each multiyear La Niña going back to 2010. October 2024…+2.76…October 2020…+2.81….October 2017…+3.35….October 2010….+2.88. The other La Niña years surrounding these in each group had a weaker October MJO in 5-6 like in 2022, 2021, 2016, and 2011. So the more amplified October years featured La Niña +PNA mismatches. With the exception of last year, these were very snowy winters. But the WPAC pattern and Pacific Jet never relaxed last winter like all the previous mismatch winters did. This is what I was pointing out last year why I mentioned early on that there were competing influences which didn’t exist during the other winters. So not to expect the same type of outcome. So this would be a first time occurrence if the MJO 5 peaked again this October in the +2.76 to +3.35 range. Seems like it’s some type of fall forcing event which affects the winter PNA during La Ninas. It’s why my guess a few months back that this 25-26 winter will be warmer than last winter was with the PNA averaging less positive than last winter did. But since the snowfall was so low last winter, it wouldn’t take much for one decent snow event to surpass last seasons snowfall totals from around Philly to Boston. Plus it’s possible that we could get a least one winter month with a decent +PNA like we saw in January 2022 even though the PNA was strongly negative in December tilting the whole winter -PNA. That was largely driven by the MJO 8. January 2022 was the last winter month around NYC which was both cold and snowy especially Long Island. We have also seen very impressive 500 ridges in Canada since the 2023-2024 El Niño generally boosting the +PNA. So we’ll have to wait for the October verification this year to know if it will be like past multiyear La Ninas following the mismatch winters like we had in 2024-2025. Always have to leave open the possibility of a first time occurrence with back to back mismatch events. But this hasn’t happened yet since 2010.

Narrowly focused into the Bay Area in an otherwise sea of warm across the Northern Hemisphere this summer.

It’s part of the record subtropical ridge expansion this decade across the Northern Hemisphere.

Yes. I get the humor involved. Not trying to rain on anyone’s parade. Just taking note of the pattern and where it has gone in the recent past with these persistent base states across the mid-latitudes.

I like to use the PDO as a marker or gauge of what the 500mb pattern is doing. Since it’s being driven during the 2020s by these extreme 500 mb ridges across the Pacific leading to similar ridging across the U.S. across the Atlantic. So the strong -PDO is more indicative of the record warm SSTs than the cold ones in the old days. Sometimes during the cold season we see an October -PDO peak like in 2024 and 2021. Then a rebound heading into both winters. But it’s a signal that a very strong subtropical 500mb ridge may occur in the following months. While we had the strong -PDO mismatch last December, there was a very strong subtropical ridge from near Hawaii right into the Western Gulf. So last December was the 4th warmest on record for the CONUS. Back in 2021 we had the October -PDO peak which rose off those lows into December. But it was a signal that the 500 mb ridge driving the -PDO was very robust. This is when we had the record breaking Aleutian Ridge that December leading to the 2nd warmest December on record for the CONUS.

The 90° reading for JFK at 10pm was pretty impressive. The all-time 10pm record high at JFK was 95° set back on July 5th 1999. So anytime we are near 90° this late into the evening people notice since it close to the record values. This allowed the record low max at ISP set earlier in the day to hold. A 79° low for anywhere in Suffolk County is very impressive. You can see it beat the previous record by +4°. The warmest low max ever at ISP was 81°.

The record WPAC warm pool and cooler waters east of the Dateline have been driving these stronger EWBs. So the actual Nino 3.4 SSTs aren’t that important. It’s the SST difference driving the La Niña background. This was the strongest early July EWB near the Dateline since 2022 but not quite as strong.The RONI also tries to approximate this difference which keeps this persistent La Niña background going whether the actual Nino 3.4 is closer to neutral or below -1.

Pattern persistence. So we get cooler and more clouds during the weekend with shower or drizzle chances. The best beach days have been during the week especially for the heat like we just experienced last few days. The next heatwave with 95° to 100° potential will be next Thursday and Friday. Models showing cooler and showers clouds chances again for next weekend also. Gets back to the stuck weather patterns which have become so common over the last decade.

The marine heatwaves were caused by the record 500mb ridge stalling in place creating clear skies and light winds allowing the seas to rapidly warm below.

The only thing consistent about Ann Arbor’s winter temperatures since the late 1800s has been a steady warming trend. December is up +4.3° with Jan at +3.2° and February +6.1°. The snowfall has seen a nice increase over this period as you pointed out. This could be a function of the warming winters holding more moisture while still being sufficiently cold enough to increase the snow. It’s one of the benefits of living in a colder region. But this benefit isn’t held by other less warm regions which have seen a steady decrease in snowfall with their rising temperatures. But relative to other parts of Michigan which can really cash in on lake effect snows, the SE corner was never a particularly wintry part of the state compared to areas further north. But at least places like Ann Arbor have seen a decent improvement relative to the old days which didn’t see as much snow.

We could see some stronger MCS activity in the day 6-10 period. But these have been finding a way to miss our area in recent years. Either to the north or south. But eventually we will get one here.

Only 1.41” for July here just to the east of KHVN with the lawns quickly turning brown with all the heat.

The SMQ average max dew point this July so far is a record breaking 74.8°. This is the same average this time of year as Norfolk, VA. Just boost the average max around 1° and this is normal for Miami in July. https://mesonet.agron.iastate.edu/plotting/auto/?_wait=no&q=76&network=NJ_ASOS&station=SMQ&season=jul&varname=dwpf&agg=max&year=1893&w=bar&hours=0-23&_r=t&dpi=100&_fmt=png

Yeah, it may be a struggle getting much below 70° around NYC. This current streak above 70° is the 17th longest 70° streak in the strongest UHI zones combined with the higher dew points and general warming. So LGA is currently at 12 days through the 16th. The top 10 starts at 19 days with #1 at 44 days back in 2020.

Yeah, it looks like a brief dip in the dewpoints Fri-Sat snd again on Mon. So this could cause a break in the 70° minimum streak since early July especially outside NYC. But it will be interesting to see if the more urban sites keep the streak going.

My old neighbor used to be an airline manager back in the days before security was as tight as it is today. He was lying on the beach in curaçao and a cute little kitten came up to him on the beach. It wouldn’t leave him so he brought it back with him on the plane and it lived with him in Long Beach.
