Just a wild guess. For a heat burst to occur a thunderstorm has to weaken over an area of dry air. The atmosphere is extremely fluid (much less viscosity than water) and in constant motion. The earth spins under the air dragging lower layers along (friction) while upper layers are moving from the earth spinning and temperature differences between the Equator and Poles. A thunderstorm is hot air rising and feeds off hot air masses next to the ground. A storm is moved by higher level winds moving the air masses (guiding winds, jet stream, etc.) The thunderstorm (or left over shower) suddenly moving over the dry air mass runs out of power (storms feeds on rising warm air). I’m betting the dry air mass is a cooler dry air mass which would suck down air and move it out from its center (cold air sinks, warm air rises) and helps the motion of the falling air in the dying storm. Late at night the air and ground temperatures will equalize briefly causing very still winds which would explain why this unique condition of sinking moist air wasn’t blown away at that particular time. All the spinning, blowing, shifting motion of the air would usually blow away conditions creating a heat blast during other times of day. Even though hot air almost always rises just the right combination of still winds, dry cool air, and a top heavy moisture laden tube of air (thunderstorm) could force the moist air to the surface creating heat as it is evaporated. (That’s why sweating works. Heat is given up to the air during sweat evaporation.)
Cliff notes: Big ol mess of water fell and turned to air and when it does that it gets hot. Don’t happen so much.

I have never heard of these before reading this thread but it made me think of a night fishing my best friend and I had fishing the CCA tournament several years ago. Back in our hey days of fishing these tournaments we would go out and start at midnight, especially when you could still keep the big black drum. This particular night we fished Ft Sumpter. We got there around 12:30am and anchored up. There was a vey light breeze and it was pretty comfortable, probably in the low 80’s. Typical summer night. It started getting warmer and warmer until I had to shed my shirt. Now it was around 2:30 am and we were both sweating like we sitting in a sauna. It got very uncomfortable. Felt just like when you are standing in the hot sun and the heat just jumps on ya and you can’t get away from it. Those that fish in the creeks at low tide on a hot summer day in boats with no shade know the feeling. That is what it felt like. We couldn’t focus on fishing and contemplated returning to the dock when all of the sudden, a good breeze kicked up and cooled things right down. It was the strangest night of fishing I have ever had and I have done a lot! That was the only time I have ever experienced that. We still talk about that night and this thread has me wondering if we went thought a heat burst. We probobly had thunderstorms the previous afternoon and early night. Things that make ya go hmmmmmmm!
Too much time, too little fishing. That’s my observation.

Had one hit us when we lived in Kansas. It went from the low 70’s to high 90’s in about 15 minutes late at night. If I remember correctly it went from calm to windy as well. The plains get some incredible weather in the spring.

Do these heat bursts sometimes smell real bad and seem to follow you when you try to walk out of them?
