Part 1

Use the data on the weather map from July 4, 2006 to create a weather map and a weather forecast for the next day. Include the locations of fronts, highs, lows, and precipitation.

Use these forecasting tips to create the weather maps:

• If there is a lot of water vapor in the air and a cold front is approaching, precipitation is most likely on its way, too.

• A change in air pressure means there will most likely be a change in weather. Falling air pressure generally means rain. Rising air pressure generally means clearing skies.

• Air masses and fronts generally move west to east.

Use these tips to create a written forecast:

• Write as if you are a weather forecaster explaining the forecast to a viewing audience.

• Explain the weather maps.

• Describe changes in pressure, temperature, and precipitation.
