DFW RECORDS ITS FIST 100 DEGREE DAY FOR THE SUMMER OF 2021

Yesterday, the temperature officially reached 100°F at DFW Airport for the first time in 2021. This is pretty late in the year for a first 100 degree day, but not as late as the latest which was none in 1906 and 1973. The average first 100 degree day is usually on or around July 1st. We average 20 days a calendar year of 100 degrees or greater. The hottest temperature ever recorded at DFW is 113°F on June 26th and 27th of 1980, our hottest summer on record. In fact, temperatures of 110°F or greater are exceedingly rare and have only occurred 12 times in our history. Five of those occurrences were during the summer of 1980. We have only hit 110°F or greater twice during this century, once in 2000 and once in 2011.

The heat will continue the rest of this week and into next, but there are long range signs that the heat will be somewhat transient, and there may be a cool down and more rain headed our way. We will have to see how that plays out. Regardless of the heat this week, it still looks like the temperature anomalies will be too great to overcome so that July will be a slightly below normal month.
