Texas Weather Swings from Extreme to Extreme in 2019
Weather went from extremely wet to extremely hot and dry across most of Texas in 2019, according to the Texas State Climatologist.
Dr. John Nielsen-Gammon said the weather turned from record-breaking rainfall in the spring to being among the driest and hottest summers on record. The jet stream migrated north, away from Texas, and tropical thunderstorms didn’t deliver in the summer months either, as temperatures continued a 1-2 degrees warmer long-term trend.
“A lot of the state picked up rain in June, after a very wet spring,” he said. “But then it started getting dry.”
A large swath of the state from the Lower Rio Grande Valley to Midland and Lubbock, the Hill Country up Interstate 35 to Dallas and much of East Texas has received less than 1 inch of rain since July 1, he said.
Some parts of the state, including around Beaumont and parts of the Panhandle, remained relatively wet. But Nielsen-Gammon said those areas are scattered.
“The monsoon season in West Texas was below normal with some parts receiving 2-3 inches, but it was spotty,” he said.
The state averaged 1.9 inches of rain total in July and August so far, which would make 2019 the third driest period behind 2000 and 2011 if no further rain fell, he said.
Nielsen-Gammon said the lack of moisture has allowed temperatures to climb.
“It’s been warm too,” he said. “The average temperature for the first 18 days of August has been the hottest on record for much of West Texas and some coastal areas. Temperatures have been in the top five hottest everywhere else except north central and northeast Texas.”
Nielsen-Gammon said 95 record high temperatures had been set, and 88 high temperature records had been tied at reporting stations around the state in August.
The drought monitor shows 22% of the state is in drought and 45% of Texas is abnormally dry, he said.
Texas A&M Forest Service Outdoor Burn Ban monitor showed 132 of 254 counties were prohibiting fires of any kind as of August 20. The agency’s Keetch-Byrum Drought Index, which measures drought and fire potential, has continued to climb around the state.
Nielsen-Gammon said some areas, including the Panhandle and parts of southwest Texas, have “opportunities for rain” in the near future, but that he expects neutral weather conditions to persist into the fall.
“There are no indications of an El Niño or La Niña pattern, so it will be a flip of the coin on weather,” he said. “It shouldn’t be exceptionally dry or exceptionally wet.”
