2. Before you read a weather map, you need to learn a few map symbols.

3. An H stands for high pressure.
is a mass of cool, dry air that brings blue skies, fair weather and light winds.

4. An L stands for low pressure.
is a mass of warm, moist air that brings stormy weather and strong clouds.

5. A front is the line where air masses meet.
When warm and cold air meets, they make stormy weather.

6. A cold front has cold air replacing warm.
Blue lines show a cold front.
Blue teeth show the direction it moves.

7. A warm front has warm air replacing cold.
Red lines show a warm front.
Half circles show the direction it moves.

8. Air masses don’t move at a stationary front.
It is shown with alternating warm front and cold front symbols.

9. Weather maps have many other symbols.
Sunny Storms
Cloudy Snow
Rainy Partly Cloudy

10. So now, if you really want to know how hot it is, you know how to read a weather map.
