I was highly amused to read the description of how a heat burst happens here:
http://www.washingtonpost.com/blogs/capital-weather-gang/wp/2013/06/11/stunning-late-night-heat-burst-in-nebraska-99-degrees-at-5-am/ because it invokes the momentum of an atmospheric packet, something that I don't think any of our weather discussions has ever brought into our explanations. Also note how the explanation proceeds as a logical-causal fait accompli, there is no physics or math involved in the explanation, just a narration of a sequence of physical causes. -- rec --
