Question by Jaquline: Why is is that most severe weather occurs at night?
because here in Texas whenever there is a thunderstorm it is always at night… i don’t know about other parts of the world, but why is this?

That’s not totally true. It could be that it seems that way to you but in reality most severe weather occurs during the daytime hours as this is where the best instability is.
For severe weather to occur at night you need strong jet dynamics in place in order to compensate for weakening instability numbers due to a loss of daytime heating. However, down in your parts instability can hold longer than here in CT b/c we cool off faster and we have the stabilizing affects of Long Island Sound.
You probably get alot of non-severe t’storms at night which are probably produced by upper air disturbances, outflow from other thunderstorms or just from afternoon heating but those storms tend to die out once the sun goes down.
