A cold front brought a round of strong to severe storms into East Texas over the weekend.
Along with high winds, frequent lightning and even reports of tornadoes, heavy rain flooded the region. That heavy rain built in along that slow moving, strong cold front from the west. With this front, storms continuously moved over the same paths, called training, causing flash flooding.
Tyler set a new daily record for rainfall on Sunday, with 5.09 inches (for December 27). Total, for the whole weekend, Tyler recorded 5.10 inches. Longview had 3.09 inches and Lufkin recorded 1.77 inches for the weekend.
So far, since the start of 2015, Tyler has recorded a total of 67.77 inches of rain. Despite a dry summer, this is 22.5 inches above average. Last year, by this time, we had only received 34.16 inches, so we have almost doubled last years rain totals.
These well above average rain totals can be contributed to El Nino. During an El Nino event, the temperature of the water in the tropics increases and causes changes to temperature and precipitation trends across the globe.
For East Texas, under an El Nino, we typically have above average rainfall, especially during the winter and spring, like we've seen this year.
While 2015 draws to a close in the next few days without anymore measurable rainfall in the forecast, under El Nino, we can anticipate above average rainfall to continue throughout the winter overall.
