This is the topic for discussion of contrail effects on thunderstorms and other similar phenomena.
The most important thing is that thunderstorm anvils create vast amounts of cirriform clouds, which can be a favourable region for persistent contrail formation. That's why some people tell something like "they spray before storms".
An interesting example. 8 June 2013 was quite a stormy day in Europe, and Moldova was affected too. Cb tops reached the altitude of 12 km, forming dense cirrus. The satellite image and the photos prove it.
Inverse relationship: Cirrus and Altostratus clouds can be a sign of warm air advection in upper troposphere. It can act like a stable layer, weakening new Cumulus congestus and Cumulonimbus clouds and even suppressing storm development.
