I live near that area. Gallatin (just northeast of Nashville) had a garage catch fire and "stuff" inside of it blew up. They don't know what caused the fire, and they don't quite know what stuff blew up yet. The fire chief basically said it was "normal household stuff that would explode when exposed to a fire." Who knows if it was propane tanks, fuel cans, etc. Still investigating.
But Gallatin also had a house under construction blow up from a natural gas leak last year, so now they've basically started an annual trend of a home blowing up once a year or so.
That's a hug pressure wave, I would think that would be a BLEVE but the tank would have to be large to do that imo. Like the sideways tanks they have at fuel depots not the 100 gallon tanks that feed a home heating system.
Assuming that radar is a Doppler radar, it basically picks up on rain and clouds, which are made up of anything from droplets to microscopic water particles. When you think about it, it's a fairly sensitive piece of equipment. I think it's plausible that a propane tank explosion could cause a brief pressure change that makes water molecules show up on the radar for a few seconds or minutes. I'm just guessing, I don't know the exact science.
