A current CONVECTIVE SIGMET forecast indicating thunderstorms implies that there is a significant level of storm activity, which can often make it difficult to see the thunderstorms themselves due to the presence of large, overcast cloud layers associated with them. These cloud layers can obscure the visibility of the storms, making them challenging to detect visually. This indicates that pilots should proceed with caution, as the turbulence and severe weather related to these thunderstorms can still affect flight safety, even if the storms are not directly visible.

While thunderstorms being visible or mild might suggest manageable flying conditions, a CONVECTIVE SIGMET warns of potentially severe conditions that require careful attention. Likewise, indicating that thunderstorms will dissipate shortly does not align with the nature of a CONVECTIVE SIGMET, which usually signals ongoing severe weather events rather than their rapid decline.
