Coldest October-April On Record In Over A Century

[This post has been corrected. There was a calculation error in the original version. I wrote some new code this morning to allow date ranges across annual boundaries.  The problem was that the code uses 0-11 as month numbers, and the NOAA data uses 1-12, so there was a month shift which affected the last year (2019) differently than the other years.]

Since the beginning of the water year (October-September) most of the US has been cold.

Afternoon temperatures since October 1st have been the coldest in the last century.

Nighttime temperatures were also well below average, for the second year in a row.

It was most likely the wettest October-April on record, but I won’t have statistics for that for a couple of weeks.

This destroys the argument that record rainfall is associated with warm air. And NOAA had the forecast exactly backwards, predicting warmth and drought.

    I would not be surprised if the wettest extends into May at the rate things are going. This years battleground between the cold and warm appears to be set up to hang over the US for longer that usual.

    can you imagine what the temps would have been if not for all the rooftops and roads?

    Let me wonder about this.
    After being very busy, solar activity has been declining. In the 1990s, Penn and Livingston concluded the trend would change to weakening. More recently, some Russians using periodicity concluded the same. Check–SC 23 and 24 have been the weakest since the early 1900s.
    Svensmark and Shaviv have been developing the theory that declining solar activity induces more cloud cover and is a cooling force.
    Check– Tony’s charts show recent and distinctive cooling.
    As well as what seems to be increasing preciptitation.
    The DMI reports that the last two melt seasons in the north were unusually cool with a high albedo. One more such season may indicate a new trend.

    The task now is to present Mother Nature’s story to a raving mob.
    On of the saddest stories following the fall of the Berlin Wall and the collapse of formal Communism happened in Canada.
    Upon his revelation, a very old and long-time Communist was quoted as saying:
    “They lied to us.”

    Saw my first Red breasted Grosbeak at my seed blocks this morning. My Indiana bird book shows them as being seasonal nesters throughout the state but I have never had a pair stick around here for the summer. They have always stopped by and taken advantage of the seed and then moved on.

    We have two pairs of red bellied wood peckers and a pair of red headed woodpeckers plus Hairy and Downy woodpeckers that are nesting near by and visit my seed blocks every day.

    During the winter we always have several cowbirds that frequent the feeder but when the weather warms they don’t show.

    NOAA predictions are nearly perfect. This one just added to their excellent score.

    It reminds me of the Seinfeld episode in which George decided to always do the opposite of what he thinks he should do. The NOAA should write their prediction and then just before they send them to press, reverse them. It would be easy. Even I can do it: “Weather outlook favors cooler temperatures for much of U.S.” See? Easy peasy.

    So I guess you’ll just ignore that Roy Spencer, a scientist who’s often associated with climate “skeptics”, has a chart, based on satellite data, that flat out shows that April was extremely warm.

    • Gator says:

      No little man, April was slightly warmer when compared to the extremely cold period that ended when that chart began. Try looking up something called an “interglacial”, and then study something called “el nino”.

      Thank God the left found a use for idiots, or you would have no purpose in life.

    • rah says:

      I think this time I’ll just ignore your stupid comment.

    • billtoo says:

      didn’t he also have a reading of -0.02 (essentially normal) for USA48 for february?

    • DM says:

      Mr. Sir, you compared an apple with an orange. The UAH average is global. Tony’s average is only for the U.S..

      • Mr Sir says:

        DM, if you look at the graph, it mentions that the Continental United States was 0.50 degrees Celsius above the 1981-2010 average in April.

        • Gator says:

          the Continental United States was 0.50 degrees Celsius above the 1981-2010 average in April.

          In other words, it was cooler than it was in the 1930’s, and far cooler than it was during the MWP. We are well aware that you doomers and haters of poor brown people constantly lie through omission.

          Why are you here little man? Your lies are refuted each and every time you come trolling. So what is your end game skippy?

  8. Lawrence Miller says:

    I have been seeing reports of unusually cold April weather world wide, when I saw Spencer’s +0.44 anomaly it was a shock as I was expecting something quite the opposite, if you look at the North American figure of +0.38 for April from this same chart and you read elsewhere that the April temperatures in the US were the coldest in 20 years, you start to question things, why do we just blindly accept this so called Satellite data? I hope someone will test this, compare this with ground based data, I would not be surprised if someone has tampered with this ‘satellite’ data. If the +0.44 data is correct, it then appears to contradict the theory of cosmic rays creating more clouds during a solar minimum.

    • Gator says:

      Satellites suffer from UHI, just like all other temp data. AFAIK, nobody sufficiently adjusts for this massive change, which is why you hear from time to time that night time temps are increasing.

  9. anon says:

    Fact checking…

  10. Greg says:

    Lawrence I was wondering the same thing. I want to see unadjusted measured surface temperature records for the past 12months. It seems like many places have had cold whether, but then all the average temperature comes out reading as one of the hottest. Even UAH with Christy and Spencer leading.

  11. Curtis Scoville says:

    Hi Tony.
    I’m trying to counter efforts by local governments here on Vancouver Island, BC to officially declare climate change an emergency, much like our federal Liberal government is trying to do in the run up to our Oct 2019 federal election. Could you do a video for your Canadian followers like me, especially those of us on the Left-Coast? I’m looking for data on Canada that goes back to 1880 and was published prior to 2000, much like the US Temp Anomally graphs you’ve shared. Alternatively, can you recommend the most trustworthy sources for Canadian climate (weather) data?
    Curtis.
