This was easily the most photogenic day with a squall line/whale’s mouth in years. We’ve posted some great shots from this on our social media feeds over the years, with an almost unmatched sky that looks ominous and scary. A whale’s mouth is the backside of a shelf cloud that often looks like you are being swallowed, with chaotic motion and cool outflow winds hitting you all at once. The day itself was kind of an expectations letdown as initial supercells gusted out rapidly into a squall line, but the whale’s mouth show made up for it photographically!
