patterns.
The location of clouds, precipitation, wind speed and direction,
temperatures and air pressure can all be shown on a weather map.
Weather maps can be used to predict future weather.

Warm Front: A warm front indicates a warmer air mass is moving in the
direction toward which the semicircles are pointing. The warm front is
drawn at the leading edge of the warm air mass. A warm front can also bring
precipitation especially in the region where the warm front is approaching.
Cold Front: A cold front indicates a colder air mass is moving in
the direction toward which the triangles are pointing. The cold
front is drawn at the leading edge of the cold air mass. When the
cold front passes the temperature drops and the rising air along
the front can bring precipitation especially in the region where the
cold front is approaching.
