The Nashville Tornadoes of March 2-3, 2020

Although life as we all know it has changed since this weather event only about a month ago, and even since just a few weeks ago when I wrote this post, we are still committed to reviewing past weather events, providing weather safety information, and generally discussing interesting meteorology topics via this blog. While we realize that life is not normal for so many of us, we hope that by continuing to blog on these important topics gives you, our readers, a sense of consistency and normalcy when everything in the world is changing by the minute.

I would also be remiss not to mention that, between the time which this blog was written a few weeks ago and the time it was pushed live to our website, yet another tragic round of severe weather impacted parts of the Southeast and Midwest on March 28. Numerous thunderstorms caused widespread wind damage and at least 30 reported tornadoes from Iowa and Illinois south to Kentucky and Arkansas. One of the largest was an EF-3 tornado which hit the city of Jonesboro, Arkansas. At least 83 homes were destroyed, and although there were 22 injuries, thankfully no fatalities were reported. The weather keeps marching on, further compounding and complicating the difficult situation of quarantine and social distancing which is already in effect due to the ongoing pandemic.

That being said, this blog post will focus on the deadly tornadoes which impacted the Nashville area on March 2 and 3, 2020.

On the evening of March 2 into March 3, deadly tornadoes marched through central Tennessee and made a direct hit on the city of Nashville. The storms were particularly deadly because some of the strongest impacts occurred after dark and during the overnight hours when most people were sleeping. At least 24 people lost their lives as a result of these storms, including at least five children under age 13. Countless others suffered injuries, and tens of thousands were left without power and suffered damage to their homes. While the most common time of day for tornadoes to occur is late afternoon or early evening, they can occur at any time of day. Let’s take a look at some of the ingredients that came together to create such a high-impact event.

March Madness – And We Aren’t Talking Basketball

NCAA March Madness officially runs from March 17 through April 7 this year, but that’s not what this blog is about! March is here, spring is just around the corner, and we are entering one of the wildest months for weather. As one of the “shoulder” or transition months between winter and spring, March is known for a smorgasbord of wild weather events. Extreme cold? Check. Extreme heat? Check. Blizzards? Check. Tornadoes? Check. Flooding? Check. Let’s take a look back at some of the most historical weather events that have occurred in the third month of the year.

Fog: A Ground and Air Transportation Hazard

Even if you are not a basketball fan, you no doubt heard the news of the passing of LA Laker legend Kobe Bryant, his daughter Gianna, and 7 other people in a helicopter crash in southern California last week. The tragic news sent shock waves across the nation. As the parent of a teenage daughter who is a basketball player nearly year-round, I found this tragedy personally very difficult to process, especially upon learning that there were teammates, coaches, and parents who were scheduled to play a game that day on the doomed flight. The children, families, and coaches left behind will be dealing with this loss for a long time to come. As I sat down to write this blog post today, I was going to write on an entirely different topic, but given the thoughts in my mind, I thought it would be timely to use the opportunity to talk a bit about the hazard that fog presents to both ground and aviation travel.

Tornado Preparedness? In December? Yep!

Hi friends. For those who might not be aware, the STM team is actually now based in two different areas – the Northeast, where we were founded, and the Southeast, where one of our team members now lives! Unsurprisingly, we now deal with very different weather-related issues. For example, at the time of this writing, I know that those of you living in New York are dealing with a winter storm all day today (December 17). On the other hand, yesterday I was able to go for a run in a tank top because the high temperature in my town was 75 degrees! Unfortunately, no location is perfect, and the southeast is known for it’s secondary severe weather season beginning in the late fall, sometimes lasting through early winter. In fact, on December 16, 2000, a powerful EF-4 tornado tore through Tuscaloosa County, killing 11 and injuring over 100. The tornado was on the ground for 18 miles, all within Tuscaloosa County. The tornado path was estimated to be 750 yards wide at its maximum intensity. Although the warnings were excellent for this tornado, the public perception still wasn’t where it should be.

NOAA Climate Analyses and Statistics

Did you know that NOAA regularly publishes articles that summarize recent weather events and the state of the climate ( https://www.noaa.gov/topic-tags/climate-analyses-and-statistics )? Generally, articles are released about twice or three times a month, and contain information about significant weather events, climate statistics for the United States for the previous month, and notes about significant studies or papers which have been published about the state of the climate. See below for details about some recent articles!

Ready or Not, Winter is Here!

December 1 is the official start of meteorological winter, although most tend to use the astronomical calendar as the official start of seasons. Check out our blog from last year for a more detailed explanation on astronomical versus meteorological winters. Regardless of the official start date of winter, it’s clear that Jack Frost has made his arrival in several parts of the country already! In fact, before anyone had even sat down to enjoy their Thanksgiving meals with their families, winter weather was creating headaches for travelers along the west coast.

Dallas Fort Worth October 2019 Tornado

While spring and summer are undoubtedly the most active times for severe thunderstorms across the United States, autumn also brings an increased risk of severe weather outbreaks. Dr. Gregory Forbes, a recognized severe weather expert, identified the second half of October and “especially November” as a notable time period for strong storm systems to develop. “In many ways, this is the counterpart to spring, when strong fronts and upper-air systems march across the United States. When enough warm, moist air accompanies these weather systems, the unstable conditions yield severe thunderstorms and sometimes tornadoes,” Forbes said. His statement came after he examined storm statistics and found six of the largest 55 known tornado outbreaks on record had occurred in the fall. Over 1,000 tornadoes impact the United States each year, and more occur in Texas than any other state.

A Look Back at Hurricane Michael

Three hundred and sixty-five days have passed since Hurricane Michael crashed into the Florida Panhandle, causing utter devastation. Michael made history as the first Category 5 hurricane (the highest category of the Saffir-Simpson scale with winds over 157 miles per hour) to make landfall in the Unites States since Andrew in 1992. It was also the first Category 5 hurricane on record to impact the Florida Panhandle.
