Anyone want to discuss heat bursts (which are caused by decaying T-storms)? Well, I'm making a thread just for that.
en.wikipedia.org/wiki/Heat_burst
In meteorology, a heat burst is a rare atmospheric phenomenon characterized by a sudden, localized increase in air temperature near the Earth's surface. Heat bursts typically occur during night-time and are associated with decaying thunderstorms.[1] They are also characterized by extremely dry air and are sometimes associated with very strong, even damaging, winds.
Although the phenomenon is not fully understood, the event is thought to occur when rain evaporates (virga) into a parcel of cold, dry air high in the atmosphere, making the air denser than its surroundings.[2] The parcel descends rapidly, warming due to compression, overshoots its equilibrium level, and reaches the surface.[3]
Back in May 20, last year, a decaying thunderstorm brought a temp spike to 86°F at 3 AM in Greenville:
