The main purpose of this ongoing blog will be to track planetary extreme, or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉
Main Topic: U.S. November Record Scoreboard and Climatological Review
Dear Diary. It’s time once again for our monthly climatological review. Here on this site, we present monthly summaries near the 8th of each month, and each is available by clicking the link below:
I’m repeating this mantra every month:
November 2022 using 1901-2000 mean data got ranked by the National Center for Environmental Information for the lower 48 states as 85th warmest, or 44th coolest since records began being kept in 1895:
The lower 48 states finally had a colder than average month. Due to our ongoing drought, cold, snowy weather was welcome in the West while above average conditions occurred in the East. It was the coldest November in nearly four decades in portions of the West. This weather pattern is continuing into December.
Brief summary for November 2022: Most reports of record heat came from the northern tier of states early in the month. A cold shot of air produced most record chill during mid-November mainly across the West and Midwest.
Here are my two U.S. Daily Record Scoreboards updated through 11/08/2022 (data compiled from the following NCEI site):
DHMX= Daily High Max Reports. DLMN= Daily Low Min Reports. DHMN= Daily High Min Reports. DLMX=Daily Low Max Reports.
Bold red-, blue- or purple-colored months, such as January 2020 and June 2021, that have ratios of >10 to 1 daily warm low records or <1 to 10 daily warm to low records are either historically hot or cold, most of which have made news. NCEI rankings are for the lower 48 states with the warmest ranking since 1895 of average temperatures being 127 (for ties) or 128 and 1 being the coldest as of 2022. Blue colors represent cold months and red warm. Those months and years with counts close to a 1 to 1 ratio of highs to lows are colored black. All-time record hottest or coldest months and years are boldly colored in purple. NCDC rankings have been color coded (under tabs in each file) such that values of 54 to 74 are black representing neutral months or years (+ or – 10 from the average ranking of 64).
Record numbers statistically matched up well during November of 2022 with that month being the 44th coldest November on record.
November 2022 had approximately a 22 to 23 ratio of record DHMX to DLMN individual record counts, so the color I used for this month was black on the top chart.
November 2022 had approximately a 20 to 27 ratio of record DHMN to DLMX individual record counts, so the color I used for this month was blue on the bottom chart.
Due to climate change, we are seeing fewer blue colors on these Record Scoreboards with time, but November 2022 was an exception to this trend.
As stated, the ranking for November 2022 was 44, which was colored blue since it was below average.
I color rankings of +20 or -20 from the average ranking for the lower 48 states of 64 black, indicating that these are near average temperature wise. The top warmest ranking for 2022 would be 128 since rankings began in 1895.
December 2022 has gotten off to a cold start across the West but especially warm across the Southeast. This trend will continue well into December.
**Special note: It was interesting that December 2021 was the warmest on record and that conditions across the U.S. this month are trending colder than average. A lot of times I’ve noticed that if there is a big spike in temperatures one way or the other on climatological charts, the following year a near opposite spike will occur…all while an upward trend overall in the long term occurs because of climate change. Nature tries to balance systems out via the old for every action there is the opposite reaction adage.**
Here is much more detailed climatology for November 2022 as complied by NOAA:

Other Notable Events
November had several notable storms that brought severe thunderstorms and tornadoes to portions of the United States:
- On November 4-5, a tornado outbreak occurred across portions of Texas, Oklahoma, Louisiana and Arkansas. A total of 31 tornadoes were confirmed by the National Weather Service, including two EF-4 tornadoes, which brought significant damage to the region including mass power outages.
- On November 29-30, severe storms and tornadoes swept through parts of the South, downing trees, damaging homes in parts of Alabama and Mississippi. The National Weather Service confirmed 11 tornadoes during this outbreak including two EF-3 tornadoes.
On November 10, Hurricane Nicole made landfall along Florida’s eastern shore, flooding the coast and knocking out power to thousands. Nicole was the first hurricane to hit the United States in November in nearly 40 years.
On November 7-10, a winter storm brought heavy snow and strong winds across much of the West. Parts of Washington, California, Montana and North Dakota reported between one to three feet of snow.
A historic snowstorm slammed western and northern New York on November 16-20 with more than six feet of snow reported in some areas, closing roads, triggering driving bans and canceling flights. The city of Buffalo set a record for daily snowfall, with 21.5 inches on Saturday, November 19. The previous record was 7.6 inches. The State Climate Extremes Committee is investigating whether or not a new New York state 24-hour snowfall record has been set.
According to the November 29 U.S. Drought Monitor report, about 57.5% of the contiguous U.S. was in drought, down about 5.3% from the beginning of November. Drought conditions expanded or intensified across portions of the Southeast, Great Lakes, Upper Midwest and central Plains. Drought contracted or was eliminated across portions of the Northwest, northern and southern Plains, Mississippi Valley and parts of the Northeast and Hawaii.
According to the One-Month Outlook issued on December 1 from the National Interagency Fire Center, the contiguous U.S. and Alaska are expected to be near normal while the islands of Hawaii have above normal significant wildland fire potential during December.
