A look at what the television weather people don’t tell us.
The high and low temperatures in Austin today at the National Weather Service (NWS) Camp Mabry Station, of 80 and 68 (degrees F) were 17 and 26 degrees warmer than normal, where normal is the National Weather Service’s (NWS) “normal” temperatures that are 30-year averages recalculated every 10 years. The last “normal” temperature calculations were for the 30-year period 1991 to 2020. For December 23, these NWS normal temperatures for Austin Camp Mabry are 63 and 42.
Today’s low temperature then, was 5 degrees warmer than the “normal” high temperature for the 23rd but, because of global warming, December has warmed significantly, meaning today’s low temperature was much warmer than 5 degrees warmer than “normal.”
The NWS 30-year normal temperatures for the month of December at Austin Camp Mabry from 1991 to 2020, were 66 and 44.
The NWS 30-year normal temperatures for the month of December at Austin Camp Mabry from 1961 to 1980, where we had already warmed a about 1 degree F on average globally, was 62 and 41.
So today in Austin, when one compares how much warmer it is today than before our climate changed, to a much more true “normal” from 1961 to 1980 (where Earth’s average temperature had already risen about 1 degree F), the low temperature today was six degrees (plus about another degree) warmer than the normal high temperature for today, from before our climate changed (much).
