Under the right conditions you can expect to see some puffs of condensation due to the adiabatic cooling of the air on the edges of the shockwave. But then only

Under the right conditions you can expect to see some puffs of condensation due to the adiabatic cooling of the air on the edges of the shockwave. But then only under the exact right circumstances (moist air, sun from behing the viewpoint, relative high pressure).
