That is where there is maximum day-time heating. Fuel for the thunderstorms. A cap builds during the heat of the day when the cap breaks storms form

Storms are driven by the latent heat released by water vapor turning into liquid water (rain or hail). During the day, the heat of the sun causes evaporation that increases the amount of water vapor, but it is usually too hot even at altitude for the formation of large drops of rain so you normally just get cloud buildup but sometimes afternoon storms if the humidity is high enough.

Once the heating effect of the sun is removed, the atmosphere cools and more condensation happens, powering the storm. Once the storm gets going, it can move according to the topography of the land, feeding off moist air. In some places this means the storm can arrive quite late at night, having started maybe 200km away.

Because the land doesn't change shape, storms follow pretty much the same path each time they form, so you get patterns. In your area it would seem the pattern is night storms. Where I live, they tend to arrive around sunset and be gone within an hour.

Most storms happen at night due to the way storms develop. The atmosphere is usually capped off which means there is a layer of warmer air in the upper atmosphere thus preventing air to rise and cause thunderstorms. During the day the conditions get worst and worst because the sun is usually out heating the ground all day. Once the ground is heated enough then the air starts to rise and clouds and thunderstorms form.

Another reason could be because when a bunch of supercells form they usually merge together as the day goes on and form a big line that can travel across multiple states. So the storm could be just out of your general area all day but could travel to your area and usually since they do not develop until late afternoon take that much time to actually reach you.

I had to read the contribution of the two other answerers to understand your question. You are talking about thunderstorms, right? A storm is usually defined as a wind superior to Beaufort scale 10. The amusing point is that when Hollywood tries to show storm at sea, it's always lightning and thunder. While thunderstorms may bring strong wind gusts as sea, it never last more than half an hour or so, and never a concern for seafarers. Deep frontal lows, on the other hand, can blow for days and build a terrible sea. I have seen such at sea where, if it wasn't for the spray generated by the wind tearing off the crest of the waves, the sky would be blue.
Regarding the thunderstorms at night, you've already got your answer, it is because of the heat build-up during the day. Mind you, it also depends on the climate; it is seldom that in my nordic Norway the heat is such that it still fuels the thunder cells at night. We get them mostly just before night fall.

Why Do Storms Happen

Because the sun makes the clouds during the time when its sunny so it can make the clouds, and then when the sun goes down and the clouds get at the heaviest is when the rain begins. I dont know if that was the best explanation, but thats how i say it and it would take to long to explain.

let me say this in a simple way,
when the sun evaporates water, the clouds get to full of water, then let go at night
