From my news report on Jan. 11: We all know that even though Dallas/Fort Worth International Airport officially only received a trace of snow yesterday and none in the first snow event earlier this month, a moderate La Niña event can deliver major snow events across Texas. Yesterday, Austin Bergstrom International Airport had a record 1.3 inches of snow breaking the previous record of a trace in 2015. The last full moderate La Niña winter occurred in 2010-11 when the Oceanic Niño Index ranged from -1.1o C to -1.7o C, according to Climate Prediction Center records. Here is a look at those winter events: Feb. 3-4, 2011: Snow extended from South Texas into North Texas. Rolling power outages reported. Heaviest snow from Dallas to Paris to Canton – 4-8”. Austin – 1”, San Antonio – 0.4”, Richardson – 5.5”, DFW – 0.2” and 2.6” (daily records). Snow depth was 3” and snow pack on the ground. Feb. 1, 2011: Widespread sleet and snow. Graham – 7”, Richardson – 2”. DFW – 0.9” hard-packed sleet. Jan. 9, 2011: Light snow in Metroplex; 4-6” from Frisco to Greenville, Richardson – 1.5”, DFW – 0.2”. Of course, other factors, such as Arctic Oscillation, North American Oscillation and the Polar Vortex can factor in to the equation. Meantime, we all know what can also happen during moderate La Niña events. Many tend to hang around for the year. The previous one lasted three years and resulted in three consecutive hottest summers on record with the No. 1 ranking in 2011 at DFW.
