Review of La Nina Winters Past and Present and Future Concerns
The current moderate La Niña has not had a huge effect on the past winter season in Dallas-Fort Worth.
Now that we are in a lull of events affecting our sensible weather elements, let's examine the just completed winter with data from the National Weather Service.
Since the start of meteorological winter Dec. 1, Dallas/Fort Worth International Airport received 6.07 inches of rain, compared to the normal value of 7.34 for a deficit of 1.27 inches.
The last top-10 driest La Niña winter occurred in 2008-09 with 1.81 inches of rain, different from several of the wettest winters during La Niña: 2017-18 (No. 1 wettest), 2011-12 (7th) and 2000-01 (8th).
Regarding temperatures, La Niña normally contributes to the warmest winters on record with 2016-17 leading the way in the No. 1 spot, followed by 1999-2000 and No. 10 warmest in 2008-09.
Finally, eyebrows may be raised on any anticipation of a scorching hot summer following a moderate La Niña event, such as those in 1956 (48 100-degree days), 1985 (28 100s), 1998 (56 100s), 1999 (33 100s), 2000 (46 100s), 2008 (30 100s), 2010 (29 100s) and 2011 (all-time No. 1 with 71 100s).
