SQUARE [Busts] Blue = no convection Gray = unproductive convection Yellow = intercept bust Red = intercept bust amid tornado warnings CIRCLE [Linear Storms] Yellow = nothing special Purple = Lightning Orange = notable Red = funnel [not mid-level shear] DIAMOND [Supercell Structures] Orange = notable Red = funnel [not mid-level shear] STAR [Supercells] Yellow = marginal / embedded Orange = notable Red = funnel [not mid-level shear] TORNADO [Yes] Icons appear where I was when chasing, not necessarily where the storm or tornado was located. On days where more than one distinct storm was intercepted, multiple markers may be used. Otherwise, a single storm or complex that was followed a long distance may only be represented by a single marker.
