46th Hottest June On Record

The NOAA web site says June. 2018 was third warmest on record in the US.

The un-tampered NOAA data shows that afternoon temperatures were 30th warmest, and not much above average.

 

The percent of days above 35C (95F) was 46th highest. Pretty close to average.

But minimum temperatures (which have been going up rapidly since the year 2000) were second warmest.

The average daily temperature range plummeted to record lows around the year 1990, and has remained there.

So what is causing minimum temperatures to go up since the year 2000?  I don’t know, but since the year 2000, NOAA has lost almost a third  of their June station data.

Moorhead, Mississippi is a good example of a station which is showing cooler June afternoons and warmer June nights.

    I dare say that UHI at the station sites also has an affect.

      I would say the same.
      It would be worth looking to see about stations that were rural having things built around them plus looking to see if there was a greater loss of rural stations than urban ones.

        + to see if there was a greater loss of high altitude stations
        than low altitude stations
        (and wether other stuff was used for the overall built+fundament)
        as different material can store energy in different(and longer)ways over night.

        • Gator says:

          There has been a loss of “cool biased” stations. When deciding which stations they would stop using, they leaned heavily on urban, coastal, and low altitude stations for reporting. This video is a great visual of what they did, and when…

            Read comment number 5 from sledge.
            Sounds interressting

          • Gator says:

            Yes the stations are still there, they are still recording temperatures, but they are dismissed because they do not show enough warm bias. Climate gerrymandering.

            That’s like ignoring crime-witnesses
            because of the color of their skin
            ((or like the censoring by facebook,youtube,
            twitter etc when you dare to oppose the leftie global gender agenda.))
            Always the same dirty tricks of the same elitists people trying to make the fake look real
            and the real look fake by controlling what is said by creating a fake PC open air mental asylum noone is allowed to leave(Hotel California style).

            Integrity was and is always the first victim of
            marxism-killed by a poison wrapped in best intensions.

      And most Snowflakes live in Big UHI cities (and have a car and a house with air conditioning).

  2. feathers says:

    I think the average min temps are going up across the country because of (1) massive urban sprawl-and-crawl which creates an urban heat island effect for a much larger area, and (2) CO2 is plant food which is greening everything that is not paved which retains humidity and keeps temps from dropping overnight.

    I know the two points appear to contradict each other but they are not mutually exclusive.

  3. Johansen says:

    They get rid of 300 stations, but yet continue to compare the data like nothing has changed?? If you did that in accounting, without adjusting the prior periods, stakeholders and a thousand lawyers would tear you to pieces…

    I don’t think moving/missing stations accounts for the decreasing maximum and/or increasing minimum temperatures.

    1) Start with the GHCN daily data files here:
    ftp://ftp.ncdc.noaa.gov/pub/data/ghcn/daily
    2) From the 105K+ stations in the tar, use only those stations with at least 5 valid summer and winter TMIN and TMAX entries from 1910 to 2017.
    3) Calculate average temperatures of the 330 stations identified by step 2 and feed the results to Tony’s PullingBackTheCurtain the program.

    This produces a fixed station station TMIN/TMAX averages from a high % (>95 per station) valid temperature set. The results closely match the “all USHCN” station graphs that Tony posted. I can change the station filter criteria and drastically change the number of stations used, which changes the resulting mins and maxes by a degree F or two, but, the min/max years and overall trends remain the same.

    If the temp has not been going up, what is the explanation for charts such as this:

    • Gator says:

      Birds are constantly changing migratory patterns based upon multiple factors. The Earth warms and cools naturally, and will continue to do so right up until the end.

      I have also seen reports of birds moving further south in the past decade. Birds, like any creature, will look to expand territories in order to survive. They will move further north, south, east and west given the opportunity.

    • arn says:

      Mammots went extinct because of increase of temperatures-
      more than 4000 years ago.
      What does this proove??
      (of course there is an alternative BS SJW theory blaming -off course -mankind(overkill theory) as some people are so stupid to claim that mankind all over the world started to hunt down one and the same species-and not just an average one but one that is extremly dangerous and hard to kill-so hard that ancient tools etc made from mammoth ivory are hard to find because they used to hunt less dangerous animals and took the ivory from dead mammoths)

      And of course you will find an increase in birds moving to the north after the harsh cold winters of the seventies are no more.
      Especially those species that can travel a hundred miles a day
      and react to changes from one day to another.

    • Hivemind says:

      If you mean the temperature graph inset in the main graphic, NOAA, UK Met Office and AUS BOM all post graphs showing warming prominently on their web pages. The trouble is that they are “homogenised” data, ie post-fraudification (I know that’s not a real word).

      They make it extremely hard to find the original “raw” data. The only one that I know of that even allows it is NOAA, but you have be really serious to find it.

    Higher mins and lower maxes have been a God-send for the Corn Belt. Means plenty of rain and close to ideal growing conditions, resulting in huge crops and more grain than we know what to do with.

    100+ degree heat can sharply reduce the corn crop. We seldom have many 100 degree days in the Corn Belt anymore, like we used to in the 1930’s or even 1980’s.
