Explanation

Cold front
(blue line

with blue tri-

angles)

If a cold front moves in, the

weather remains changea-

ble and there are often rain

showers and thunder-

storms. The air tempera-

ture decreases.

Warm front
(red line with

red semi-cir-

cles)

A warm front may cause

more prolonged steady

rain, more cloud cover and

a slow rise in temperature.
