  1. WEATHER FORECASTING

  2. What affect does the weather have on the world? • What are you going to wear today? • Do I need to leave early to get to work? • Why do farmers pay attention to weather? • Is our baseball game going to be cancelled today? • Can we go to the beach today? • Do I have to water the lawn today? • Can we go on our field trip today?

  3. What helps Meteorologists Predict the weather? • Computers • Satellites • Climatology • Trends (study patterns of weather from previous days or even years) • Weather can be predicted up to about 5 days and after that it is more of a guess due to all the different atmospheric pressures that change and bring different weather

  4. Air Pressure Symbols • High and Low Pressure Systems • A blue "H" means a center of high pressure (usually calm, sunny weather). • A red "L" means low pressure (which can mean storminess). Most fronts extend from low-pressure centers.

  5. Cloud Cover Symbols • If the circle is empty the skies are clear. • The circle is white if it’s cloudy. • A line within the circle or a half-filled circle means "partly cloudy."

  6. Forecasting MapsWhat do you look for? • Look at all the symbols on the map and determine the weather pattern associated with them. • Look at the directions of the fronts moving through an area. • Try to determine whether there is low pressure or high pressure in the area. • Now, put them all together and determine the weather!
