Why does it seem there are more big storms at night?

I have always noticed huge thunderstorms with gusting winds happen much more commonly at night than during the day; these storms often seem to last much longer too. (keeping me up!) Is there a scientific reason for this, or is it just coincidence?

Most of the time it's because thunderstorms don't start forming until well after the peak heating of the day occurs (typically around 2pm or so), because that is when the atmosphere is the most unstable and contains enough energy to break any capping environment.

Well-developed storm cells with steady surging cycles tend to 'feed' off of this heat energy and can persist into the late evening and night time hours. This is why you typically don't see thunderstorms in the morning,  although if a frontal boundary is nearby, that would be enough to maintain the needed instability around the clock for thunderstorm formation to occur.

Hope that helps.
