30 years ago a historic storm impacted parts of the South, Mid-Atlantic, and Northeast parts of the United States. This historic event was later dubbed the Storm of the Century, Super Storm 93, or the Blizzard of 1993. It is hard to believe that this event unfolded 30 years ago March 12th-14th 1993. I remember this event like it was yesterday because my area was hit hard with this storm system.
The week before the Super Storm impacted my area temperatures were in the 60’s and sometimes in the 70’s. For my area (Southeast Tennessee and North Georgia) that was nothing out of the ordinary. In fact, it was normal to have highs in the 60’s and 70’s going into the middle of March. I can remember local meteorologists stating that the following week we would have to really watch as a potent storm system could develop in the gulf. The local meteorologists also stated that how very cold air would be in place and we could have a historic winter storm. I was 8 years old and I can remember people brushing it off. A lot of people did not believe a significant winter storm would occur in the middle of March. Normally in March my area has to worry about severe thunderstorms including tornadoes, but not a winter storm.
Around March 9th 1993 the local meteorologists were using the term blizzard. Some of the local meteorologists said we could get over 18 inches of snow. The Weather Channel said that my area alone could get 18-26 inches of snow. In addition, all meteorologists used the term thunder snow as we could hear thunder when the blizzard moved in. I had been into meteorology since age three, so I knew what a blizzard was. I was full of glee that I could experience such a historic event. I kept thinking to myself “will I really see and experience a blizzard. Will I also get to see lightning and hear my favorite sound thunder”.
Around March 10th/11th very cold air filtered into my area. The seasonable March weather was replaced with very cold temperatures. Also the low pressure system started to deepen in the Gulf of Mexico. The storm moved northeast. Late March 12th the storm system started to move in. Snowfall started to occur later that night. On March 13th I heard the thunder and saw the lightning. I gleefully jumped out of my bed and I could not believe what I was see outside of my window. The snow was coming down so hard that I could not see. Moreover, the wind was really howling. My parents where in shock as they could not believe what they were witnessing. They told me that nothing like this had happened in their lifetime. My parents told me they had witnessed flooding, very bad thunderstorms, and tornadoes, but nothing like this.
The snow kept coming down and the wind continued to howl. As power lines started to break we lost power at my house. By the nighttime the snowstorm had ended for my area. I later learned that as the storm system moved inland it produced a storm surge on the Gulf Coast. The surge was described as being like a tropical system. In the state of Florida a squall line produced damaging winds and 11 confirmed tornadoes. Some of the tornadoes were F2 or higher. The next day me and my parents had to get a yardstick to measure the snow. I observed 24 inches (2 feet) of snow, Chattanooga got 20 inches, several places in North Georgia got 18-21 inches, and Knoxville TN got 12-15 inches of snow. Some of the higher elevations in my area saw more than 26 inches.
We were without power for a few days. Due to the temperatures being very cold the snow did not melt. To keep the house warm my parents used the wood burning heater. It felt funny having to use the wood heater in March. Eventually, power was restored, but we could still not get out to go to work or school. In fact, school was shut down for the entire week. After impacting my area the storm system moved up the East Coast of the USA. The storm system would bring more than 3 feet of snow to some places in the Mid-Atlantic and the Northeast.
When power was restored we were able to see our local news stations. Local news crews showed pictures. Some of the snow drifts were more than 3 feet against buildings and homes. Several trees and power lines were down. There were several pictures of cars stuck in the snow. Eventually, warm weather returned and the snow melted. As the snow melted another problem developed and that was flooding. When the snow melted it saturated the ground. 20-24 inches of wet snow would equal 2-4 inches of rain. Indeed, many counties reported flooding. I was still in shock at what I witnessed. As the years went by my area saw many severe weather events including tornado outbreaks, which is what we normally have to worry about. My area has also seen some winter storms that produced ice or snow. But none of them rank near the top as the Super Storm of 93 did. Indeed, the Blizzard of 1993 was a historic event for my area.
When I was in college I took a lot of atmospheric, climate, and earth science classes. I would earn two science degrees. Basically, I’m a meteorologists, just not on TV. I can remember one of my professors doing an analogy of why this storm was not just historic but bad. From Mid February to Middle of March there was an active jet stream across the Mid and Upper South. This is why in late February my area was hit hard with a severe weather/tornado outbreak in late February 1993. This same jet pattern carried waves of energy over my area. A few days before the blizzard a Polar Vortex brought very chilly air all the way down to Central Mississippi, Central Alabama, and Central Georgia. In fact, some places saw record lows for the month of March. Then you had a low pressure system developing in Texas. This was nothing out of the ordinary as a lot of times these lows develop in the Gulf and move northward. This is sometimes how my area can get severe weather. But this time there was very chilly air in place.
The water temperatures in the Gulf were unusually warm for the month of March. As the wave of low pressure moved into the Gulf it started to rapidly deepen into a very strong low pressure system. The High Pressure to the north and the jet stream pulled this storm system northeastward. The warm water temps in the Gulf not only fueled this storm system but it provided it with lots of moisture. This is why there was high snowfall amounts in places like Dalton GA, Chattanooga TN, Gatlinburg TN, and etc. The warm air from the Gulf also caused warm air to stay over Florida. The storm system winds aloft provided wind shear. Severe thunderstorms developed and moved over Florida. Ingredients were favorable for several tornadoes and that is what happened. The winds around the storm’s center and wind aloft also created a storm surge on the Gulf Coast.
As the storm moved off the East Coast it found another power source for fuel and moisture. That source was the Gulf Stream. The Storm started to intensify some more. As it moved inland it produced snowfall totals over 30 inches in the Mid-Atlantic and Northeast. I remember my professor talking about this particular event for almost the entire class period. Indeed, this storm was the answer to one of the questions on an exam. Looking back on it now it is easy to see why this storm was called a Super Storm. This storm had everything in it, storm surge, tornadoes, high winds, and historic snowfall amounts.
One could argue the Blizzard of 1996 was similar to the Super Storm 93. In fact both storm systems originated in the Gulf. The Blizzard of 1996 brought freezing rain and snow to the south, but nothing like 1993. Then the storm rapidly deepened over the Gulf Stream. The Blizzard of 1996 produced 3 feet of snow in parts of Pennsylvania, and Maryland. Other places in the Mid-Atlantic/Northeast saw 20-30 inches from the storm of 1996 just like the Blizzard of 93 had done.
Here it is 30 years since the Blizzard of 1993 occurred and I remember it like it was yesterday. I don’t think i will ever forget this storm due to how historic it was. I have since studied and analyzed this storm system. I am still amazed 30 years later on how all the ingredients came together to produce the Super Storm of 1993.
