Scheduling and weather...connected?

[ArcherII]

Something that I was wondering and searched in the forum w/o luck.
The thing is I have some routes with nearly 8% of delay probability. But those are some. Maybe 4 or 5.
But, in the other hand, I have a lot of routes that have big delays (+20min) and mostly the main reason is scheduling, but it comes hand in hand with weather-induced delays.
My question is, regarding that this is quite understably and it happens IRL... Are scheduling delays in a flight induced by weather delays in a prior flight?

I don't know this will help or not, but from this:
https://www.airwaysim.com/forum/index.php/topic,24512.0.html
all the weather related delay, prior or during the flight categorized as weather delay. But, I don't don't really know, because I have some mess in delays too, over 27000mins in weather delay. So, I'm also wondering...

Just a thought. Maybe the bad weather generates a chain effect tha affects later flights. And thus the first flight (conditioned by say a thundersorm) landed 30min later than scheduled, it may had "eaten" the later flight's turnaround and departure time and so on and so forth.

This is relly importan because I spent a lot of time rescheduling my routes to rise punctuality.
