  1. Reading a Weather Map To find the weather map go to: http://www.weather.com/maps/maptype/currentweatherusnational/index_large.html

  2. Daily Objectives 2/25 • Complete the “Reading a Weather Map” Worksheet. • Understand weather symbols to read and interpret a map. • Predict future weather patterns. • Do you have colored pencils?

  3. Cold Front Symbol Information Cold, dry air replaces warm air. Following a cold front, temperatures drop dramatically. Precipitation can occur along the front line. Including thunderstorms.

  4. Warm Front Symbol Information Warm moist air replaces cool dry air. Following a warm front, temperatures increase. Light precipitation can occur along the front line.

  5. Stationary Front Symbol Information A stationary front occurs when a warm or cold front stops moving. Noticeable temperature and wind shifts occur when traveling across the front line. Once the stationary front starts moving again, it becomes warm or cold.

  6. Occluded Front Symbol Information Occurs when a cold front catches up to a warm front. A cold front travels faster than a warm front. Changes in temperature, humidity, and winds occur with passage of an occluded front. (See diagram to the left.)

  7. High Pressure Symbol Information Winds flow clockwise around a high pressure system. High pressure is usually associated with little cloud coverage.

  8. Low Pressure Symbol Information Winds flow counter-clockwise around a low pressure system. Low pressure is usually associated with cloud coverage and areas of different weather depending on placement of the fronts near the low pressure. (See information on the left.)
