How long will the plane be delayed in thunderstorm weather?

How long the plane is delayed in thunderstorm weather can be divided into two situations:

1. If it is a small thunderstorm, the flight delay may be only a few minutes.

2. If it is a large-scale thunderstorm, the flight delay may be as long as several hours or even a whole day. In addition, if the flight has taken off but is affected by thunderstorm weather, it may wait or return at other airports, and the delay time will increase accordingly.
