Interesting fact: mammatus clouds have often been associated with approaching tornadoes. In fact, this is a common misconception. While mammatus clouds do form on most tornadic thunderstorms, they form on many thunderstorms in general (including non-tornadic) and there is no known direct correlation between tornadoes and mammatus clouds. Mammatus clouds are often best seen after a thunderstorm has passed. Also, as mammatus clouds form on thunderstorm anvils, which are much larger than the part of the thunderstorm where the worst weather happens, it may well happen that you see mammatus clouds without actually being impacted by the thunderstorm.

Fun fact: contrary to popular conspiracy theories, mammatus clouds are not a recent phenomenon and were first described in 1894 by William Clement Ley.
