how can you tell when a weather change is coming
Vienna has pretty warm summers this I know because I am in Vienna at present and can tell you that Winter can be pretty cold too.
One way you can tell is if you can't feel cold air during the summer (that happened to me) and it is either low or you may have a leak. Mostly you can't feel cold air and that means it needs to be refill it. Careful during the summer, it can crack and leak from overuse.
if you mean weather then I can tell you that Wales have winter, spring, summer and autumn. If that's not what you meant then maybe a more specific question would help you get the correct answer :-)
meteorologists tell the weather by looking at the sky because of the clouds. Every cloud could tell the weather. Different types of clouds tell different weathers.

Thunder storms occur when hot air and cold air run into each other. Therefore one way of predicting them is if you notice a cold front has come during warm weather, or a warm front during cold weather.
