Terrible Texas Twisters 

The October 20, 2019 Tornado Outbreak in North Texas

By Don Padilla
Tornadoes, (or twisters if you're a local) are nothing new to Texas. Nearly every other week during the Spring there's a tornado watch for a day or two due to a storm system moving in, but nothing serious has ever devastated North Texas in recent memory. 

Until October 20th, 2019.

I was in my house trying to ignore the storm outside while my parents were watching the Dallas Cowboys playing that Sunday night. We were given ample warnings by the National Weather Service to prepare for a strong cold front moving in, but like always we weren't worried about it. Cold fronts were common in the fall, where a mass of cold air from the north would sweep in and make contact with warm moist Gulf air mass. This often produced violent and windy storms around Texas, Oklahoma, Arkansas, and Louisiana, but it usually was never any cause for concern. 

Then, I heard the Emergency alarm go off on the T.V. A tornado warning was issued for our county due to a Tornado capable storm moving in. Tornadoes are the result of circulation from a storm system, usually a supercell thunderstorm.

A supercell thunderstorm is a large storm with rotation, usually driven by cold air that sinks to the ground and hot air that rises. If this rotation grows strong enough, it can form a Tornado, a twisting column of rotating air moving at hundreds of miles per hour. During the night, the cold front had formed several supercell thunderstorms that rotated a lot, forming the perfect storm for a particularly strong tornado that night.

An EF-3 Tornado formed in Northern Dallas, with winds up to 140 MPH, and made its way up through residential Dallas befoe hitting the northern suburb cities of Ricardson and eventually Sachse. The tornado in total managed to create around $2 Billion worth of damage, making it the costliest tornado disaster in Texas history. Miraculously, no one died or was even seriously injured during the event, mostly due to the early warning and detection by meteorologists.

As for my family and I, we were safe in Plano, just a few miles north of the tornado's path, though there was still a lot of obstructions on the road and fallen trees and plants. This was the closest I have ever been to a tornado in Texas, so it was certainly a memorable experience.

  1. Wow! I really liked your post, and I'm interested in how the meteorologists mitigated the effects of the tornado. Since there were no deaths were people told to stay inside their houses and drop to the floor? Or how did they inform the public about the impending tornado?
