How Many 100-Degree Days Will Dallas Face This Year?
We Asked Three North Texas Meteorologists To Guess How Many 100-Degree Days Dallas-Fort Worth Will Be Forced To Endure In 2021. Heres What They Said. The 2021 summer has arrived in North Texas, and one thing is already sure: Its already hot as fuck outside! As residents here, were all supposed to be used to steaming summers here in Dallas. Granted, some summers are worst than others. For some Dallas residents, the crunch of unsweet tea-colored grass underneath their shoes could bring back flashbacks to the summer of 1980, a record-breaking high-temperature summer  and one of the deadliest heat waves in history  that saw the region endure 69 total days at over 100 degrees, 42 of which came consecutively and 28 of which even topped the 105-degree markers. More recently, the summer of 2011 was similarly brutal  and in some ways worse. That years August was the hottest month on record in Texas history, and the entire year actually saw more 100-degree days than the summer of 1980, with 2011 actually boasting a round 70 days over the 100-degree mark. Furthermore, 2011 broke the 1980 record for highest average low temperature, checking in at 78.9 degrees to 1980s 76.7. In order to find out, we asked some local meteorologists to send us their estimates for how many 100-degree days we will have in 2021. Heres what they had to say. David Finfrock (NBC 5)  Estimated 100-degree days: 12. Explanation: Our Texas summers with the greatest number of 100-degree days occur when it is very dry. Humid conditions like we have experienced recently because of the heavy spring rains arent as conducive to really high temperatures. For that reason, I think we will have below the average number of 100-degree days this summer. The average is now 20. But I am guessing we will probably see no more than a dozen 100-degree days this summer. So my number is 12. Of course, because of the high humidity, there will be many more days than that feel hotter than 100  Evan Andrews (FOX 4)  Estimated 100-degree days: 25  Explanation: This one is easy, since Im not a big fan of extended forecasts. Thats mainly because I dont consider it forecasting. Its just playing the odds, based on patterns from the past. For example, the odds said a La Nia winter was going to be warm  and then February happened. No one forecast such a cool wet May back when spring started in March, either. As a matter of fact, the prediction in March was for a very warm and dry spring. And, while La Nia is gone, the only pattern seen so far is the huge hot high out west. If you look at the [recent] prediction from the climate prediction center for summer, that seems to be what is taking the odds in their forecast. Persistence! My prediction of more normal 100-degree days  lets go with 25  is actually based on the fact that the sensor they use at DFW [International Airport] has been running higher than most other Metroplex sites lately by a degree or two! That raises the odds, Id say! Very scientific.  Jeff Ray (CBS 11)  Estimated 100-degree days: 16  Explanation: I think the active hurricane season lends a hand here, as well as the persistent high-pressure dome over the southwest. I believe the hottest weather holds off until the end of July into August; thats when we usually have a run of 100-degree days. I wanted to go real low  12  but I have to take in this sudden appearance of dry conditions and the general warming trend over the last decade. Im staying under the normal of 20, though. Ill go with 16.
