This page is a useful bookmark for past “famous” tornadoes, supercells, and other storms in the United States and Canada. The list was procured by how impactful the storms were to civilization, how abnormal they were for the area, or how memorable they were to storm chasers.
Each case comes with documentation, a proximity sounding from unmodified RAP and ERA5 reanalysis, (see disclaimer), and storm-centered NEXRAD imagery. Data are valid at the time nearest the climax of the event (e.g., when a tornado was reported, or when the most well-known photographs were taken).
This archive sparks the question, “why did this happen?” Similar environments make similar storms, but a storm’s environment isn’t just skew-Ts and hodographs. If you’re wondering “how did this sounding do that?“, remember to check for boundaries, cell mergers, and chaos!

A series of two EF4 tornadoes, one of which was extremely long-tracked, that quickly became colloquialized as the “Quad-State Tornado”, though surveys found a significant break in damage. This tornado family killed 65 people, leveled large portions of multiple towns along its path, and along with another tornado this day, stirred controversy over workplace preparedness.
Neither RAP nor ERA5 will not perfectly represent the observed environment.
In general (especially prior to 2021), RAP has a bias toward warm, dry surface conditions and weak low-level shear, especially on drier days. ERA5 has a bias toward cool surface temperatures and weak buoyancy. Soundings were not adjusted for observed surface variables or storm motions.
Certain artifacts are inevitable. RAP soundings will often display saturation aloft that masks otherwise drier profiles near convection. RAP may also feature unrealistic low-level moisture distributions, such as high surface dewpoints in otherwise dry boundary layers. ERA5 soundings are occasionally marked by an incongruent disconnect in the low-level thermodynamic profile.
