A Front: When two opposing air masses (armies) meet
there can be large temperature differences on either side of the front
when a front passes there is often a change in wind direction and temperature
5
Cold front
Occurs when a colder air mass overtakes a warmer air mass.
The cold front moves faster than the warm air and pushes it upwards
Results in heavy rain and violent thunderstorms
Cold fronts are big bullies!

Results in clear to partly cloudy skies and occasional light rain.
A face off! A stare down!
