Objectives:
Explain how data is collected for weather maps and forecasts.
Identify the symbols used in a weather station model.
A meteorologist is a person who studies the weather.
They measure the temperature, air pressure, winds, humidity, and precipitation. They use this information to make weather maps. These maps help us forecast the weather.
When conditions indicate that severe weather might occur, the National Weather Service issues advisories.
Severe weather is considered:Thunderstorms, tornadoes, floods,
blizzards, and hurricanes.
A station model is a group of meteorological symbols on a weather map that depict weather information for a location.

Isobars are lines joining places on a map that have equal air pressure. Isobars can show how fast the wind is blowing. If they are close together the wind is stronger.
Isotherms are lines joining places that have the same temperature.
Meteorologist cannot always predict the weather accurately, because weather conditions change.
