Dry

Rain and clouds for a few days

A warm air mass gets trapped between two cold air masses
What happens when two cold air masses meet
They ban together the air temperature drops as the warm air mass becomes occluded or is prevented from reaching the ground as the warm air mass rises and cools clouds gather in rain or snow may fall
What is it called when cold and warm air masses meet and neither one can move
A stationary front
In a stationary front warm and cool air meat
Water vapor in the warm air condenses into rain, snow fog or clouds
