Earliest 92°F Day on Record!
Title says it all - today was the fourth earliest 90°F+ day on record and the earliest 92°F by some five days. The GHCN record for us stops at 1937 so I can't actually capture the 92°F on May 15th, 1924 (which is the closest 92°F+ occurrence to today).
The y-axis shows the month fraction. 5.0 = May 1st; 5.5 = May 15th and so on. On the x-axis we just have each year.
Let me know if you have any questions!
Edit: The +/- x days denotes one standard deviation in the data. Realistically three standard deviations occur regularly so we could probably go +- 6 weeks but then the text is irrelevant anyways. Also, no world in which we would get a first 92°F day on July 30th or later in the 21st century. Do with that what you will, just take that bit of text with a grain of salt!
Edit 2: This graphic is created by me, myself, and I; there is no guarantee for accuracy (though I would like to think it is!) and this is not affiliated to anyone else. The data comes from GHCN-daily https://www.ncdc.noaa.gov/cdo-web/datasets/GHCND/stations/GHCND:USW00023185/detail and is visualized via Python.
