The Climate Lottery: Fall 2019 Contest

The Climate Lottery is a forecast contest free to play by giving your picks in an e-mail or in this post’s comment section. No prizes will be given out for the contest, which is for educational purposes only. The main purpose for the contest is to make people interested in National Center for Environmental Information climate products. The special account that I have set up for the contest is guywalton10@gmail.com. This time I will make a personal pick, following along with any players.

The National Center for Environmental Information ranking numbers for average temperatures of the lower 48 states for Fall 2019 will be posted on or shortly after December 7th, 2019 which will be the official “Climate Lottery” numbers of the contest. Any subsequent changes by NCEI after their initial posted rankings will not be valid for the contest…but those ranking numbers will change with time.

The winning Climate Lottery numbers for Summer 2019 (JUN, JUL, AUG)  were 65/99/113 with a Power Ball number of 101 for the season. 

Hello again to all weather and climate geeks out there. Summer 2019   turned out to be an well above average season, temperature wise, for most of the United States. If you wish to play “The Climate Lottery” pick one number between 1 and 125 (with 1 representing the coldest possible ranking and 125 being the highest possible ranking) for September, October, and November 2019. Also, pick a “Power Ball” or overall ranking number for Fall 2019 between 1 and 125. The Power Ball ranking will serve as a tiebreaker for any close picks between contestants. Your picks are NCEI rankings for average temperatures across the lower 48 states. Since 2019 is the 125th year that the National Center for Environmental Information has been ranking years since 1895 all months for 2019 will have a warmest ranking of 125. The year 2019 would be the 125th year. Those rankings for 2019 will have a range from 1 to 125 with the coldest ranking being the number 1.

Please give your picks to Guywalton10@gmail.com before October 5th, 2019. If you wait until just before October 5th to make your picks you can make an educated guess as to what the ranking for September will be (and, also a heads-up guess for October). All data can be found at the National Center for Environmental Information site noted here: https://www.ncdc.noaa.gov/temp-and-precip/us-maps/1/201702#us-maps-select

The Power Ball (or overall National Center for Environment Information) number for Summer 2019 for the lower 48 states was 101, which was well above the average ranking of 62.5, for the lower 48 states. In the Climate Lottery game, I’ve defined each individual lottery number as rankings for each month for the lower 48 states, Power Ball numbers as those for each season, and Mega Ball numbers as those for each year. 

Chances for an entire season of below average temperatures are becoming much less likely across the lower 48 states due to carbon pollution. The whole point of these posts is to demonstrate how skewed temperatures have become towards warmth due to climate change. Of course, as far as the globe goes, the larger an area that is compared to average, the more likely that area is to be above long term averages. What has happened, so far, this decade is yet more proof of the climate lottery game being loaded for warmth in the United States. Balls coming out of the Climate Lottery hopper are likely to have high numbers, but we saw some low numbers scattered about the country going down to a statewide basis this summer. 

Here’s a breakdown of the National Climatic Center’s ranking numbers by state for Summer 2019, which was ranked as 13th warmest (or a Powerball ranking of 101):

The Southeast had a warm spring while the wet Midwest remained chilly. The West had near average conditions.

The following is a breakdown of each month for Summer 2019. Each chart shows “Climate Lottery” numbers for each state (or rankings) from a scale of 1 to 125.

In June the overall ranking for the lower 48 states was 65 (out of 125): 

Most of the Plains and Midwest were slightly below average due to what was a very wet spring. It took a lot of incoming solar radiation to dry wet ground, resulting in relatively cooler conditions from what I can gather. June was the coolest month of the summer.

In July 2019 the overall ranking was 99 for the lower 48 states (out of 125):

Most states saw relatively warmer averages except in the far West during July.

In August 2019 the overall ranking for the lower 48 states was 113 (out of 125):


Every area of the country was warmer than average except for the Midwest. Arizona, New Mexico and Texas had their second hottest August on record. August 2019, overall, was the hottest month of the summer, a average temperature wise.

The following are the rankings, so far, for individual months or “climate lottery number picks” for the 2010s:

The average ranking for 2019 is 62.5 since the coldest ranking would be 1 and the hottest 125. I have color coded all rankings for this post at or below 42 blue and all those at or above 82 red with rankings + or – 20 from the mean value of 62 black. With time, the rankings for each individual month, season and year will change as more data becomes available from NCEI. Also, for reference, the annual or “Mega Ball” numbers are shown on the chart. The mega ball number for 2018 was 111 meaning that 2018 was the thirteenth warmest year on record for the lower 48 states. 

Seasonal or Power Ball rankings for winter are those for DEC/JAN/FEB, spring are MAR/APR/MAY, summer JUN/JUL/AUG, and fall SEP/OCT/NOV. Also, keep in mind that NCEI rankings for seasons are not merely an average of rankings of individual month of a season or year as was the case for Summer 2019- 65/99/113 P.B. 101:

Notice that since the start of 2010 only four out of thirty-nine seasons have been well below average or “blue.” Twenty-eight out of thirty-nine seasons since 2010 have been “red” or above average. Summer 2019 added another tally to the red total. Indeed, the Climate Lottery hopper is very much loaded for above average temperatures for the lower 48 states looking at recent history. Yes, the “casino of climate averages” is cheating causing the “house of warming” due to carbon pollution to win just about every season.

 I hope that everyone will have a great fall.
