A "front" is the boundry between two air masses which differ in pressure and temperature. The lighter,warmer air gets pushed up the wall of the other air mass. As the air rises, its water vapor cools below the temperature at which it can remain a gas. It condences into tiny droplets of fog which grow in size until they fall to earth as rain or snow, depending on the temperature.

I hope you know something about weather fronts.
The warm front is a boundary where warm, moist air on the surface is pushing colder air and riding over the colder air. This often leads to steady rains as the overriding warm,moist air cools and drops precipitation to the time the warm, moist air is on the surface.
The cold front is the reverse process; cold, dry air is pushing under warm, moist air and pushing it along. Often, this process causes showers and thunderstorms to occur in front of the transition of air masses at the surface.
A stationary front can occur where there is not consistent movement of two air masses. This can lead to showers and rain along the frontal line.

Those lows and highs,
They sink and rise.
The air begins to move and flow.
It circulates
At different rates,
And that creates the winds that blow.
The highs are nice,
They bring fair skies, (ah ha!)
But a low will often bring you clouds or rain.
And when they bump,
They form a front.
A changing of the weather in between.
As the highs and lows push and shove, the weather front begins to move! And if a front moves into town, it means a storm may just come down!

You can't get rain without a cold front meeting a moisture-saturated warm front. In winter the tropics are still pushing up moist air, so we get snow. Don't blame the Canadians for the snow in the U.S.

Hi. A mass of air that is hot can meet a mass of air that is cool. The boundary is called a FRONT. Usually results in rain.

It will cause the water vapor to condense.
