A cold front, by its very name, has colder air behind it, but when cold air tries to oust warmer air the result will often be some nasty weather for a time.

The rain from a warm front starts lightly and becomes moderate with time but it all tends to happen slowly. Not so with a cold front. Here the sudden arrival of cold air lifts up the warm air and sets off sometimes violent showers and thunderstorms at the same time as it rains heavily.

There are often nasty squalls and almost invariably a veer of wind (NH, back in the SH). Things are often cold, wet and chaotic when cold fronts appear – sometimes without much warning. But a cold front’s weather is like a warm front’s in reverse. The rain may start heavy but it soon tails away to moderate and then light before ceasing altogether. On the whole, the weather of a cold front passes twice as quickly as that of the warm front.

What’s behind the cold front?

Eventually the sky lightens and breaks behind a great swathe of high cloud, including cirrus. Then, if it is daylight, there is a blue-sky gap before heap clouds begin to build. These may remain too small to produce showers but at other times heavy blustery showers of rain (or snow) set in. The air now feels different. It is cooler and clearer – you can often see for tens of miles (or kilometres) and you could now be in for a spell of better weather.

Sometimes this more benign spell will last for days and at other times only for hours when another depression is hard on the heels of the one just gone.

What’s good about a red sky at night?
