What would you say that the most impressive temperature records for each month are in the United States? These are the most impressive readings considering the location, rather than the highest or lowest readings.
Here are ones I can think of:
High: 98 at Zapata Texas on 1/5/1997. I just went with this one, but there are a lot of other runners up.
Low: -27 at New Market Alabama on 1/30/1966.
High: 85 at Eureka California on 2/17/1930. This was the warmest reading recorded at Eureka between 12/1/1886 and 9/20/1983. It is still the 4th warmest reading in ~132 years. Runner up would probably be 100 at San Antonio Texas on 2/21/1996.
Low: -30 at Salt Lake City on 2/9/1933. There are a lot of contenders here, but this one really stands out and there haven't been any close readings outside 1933.
High: (tie) 101 at Grant Nebraska on 3/21/1910 and 90 at Edmore North Dakota on 3/22/1910.
Low: -50 at Snake River Wyoming 3/17/1906. It was the second coldest reading ever recorded here.
High: 100 at Fargo North Dakota on 4/18/1980.
Low: -34 a Bergland Michigan on 3/31/1923 or 4/1/1923 or -30 at Humboldt Michigan on 4/1/1923 (depending on when the Bergland reading was recorded).
High: 112 at Maple Plain Minnesota on 5/31/1934.
Low: 1 at Landmark Idaho on 5/23/1944. Impressive because of the lateness in the month.
High: I'd go with the 128 at Lake Havasu on 6/29/1994, but I'm skeptical of the reading. I might go with Richardson Alaska on 6/16/1969.
Low: 31 at Cleveland on 6/11/1972. This was the coldest reading anytime between 5/16 and 10/3.
High: 121 at Steele North Dakota on 7/6/1936.
Low: 17 at Tropic Utah on 7/2/1902. This one seems legitimate, but incredible. Nearby Loa hit 19. Tropic's 7/2/1902 reading was the coldest temperature recorded anytime between 5/22 and 9/26. Loa's reading was the coldest temperature recorded anytime between 5/26 and 9/10. Tropic Utah has only seen three other July frost in 125 years and the 17 is way out of the ordinary.
High: 120 at Ozark Arkansas on 8/10/1936
Low: 5 at Bowen and Hegben Dam Montana on 5/24/1910. At Hegben this is within one degree of the September record and 3 degrees colder than the May record.
High: 126 at Mecca California on 9/1/1950. The desert southwest usually has high readings usually more common early season, but the September 1950 heatwave was in a league of its own.
Low: (tie) 1 at Rock Springs Wyoming on 9/18/1965 and 1 at at Gordon Nebraska on 9/25/1926.Rock Springs reading is 4 degrees colder than the record low in October and 2 degrees colder than the record low in April.
High: 97 at Fargo North Dakota and Moorehead Minnesota on 10/11/2015.
Low: -12 at Modena Utah on 10/30/1972. This is 5 degrees colder than the November record and 7 degrees colder than the March reading. This was the coldest reading anytime between 2/28 to 12/10.
High: 101 at LAX on 11/1/1966. This is 4 degrees hotter than the July record and 3 degrees warmer than the August record.
Low: There are lots of contenders here, but I went with 1 at El Paso Texas on 11/29/1976. Only three January temperatures were colder and none in February or December. The -38 at Eagles Nest might be a good runner up as were several locations out west in 1955 and 1985.-53 at Lincoln 14NE, MT on 11/16/1959 is another contender for runner up.
High: 58 on 12/5/1934 at Fairbanks Alaska. In the lower 48 1939 has some runners up, but none really compare to the 58 reading at Fairbanks.
Low: It's a tough choice, but I went with -48 at Mamaba Washington on 12/30/1968. Record lows in January are -42 and the record low in February is -40.
Any disagreements with the above? What are some other contenders?
