11.1.15 Weather Forecast
The Weather Forecast data provides Surface Analysis and City Forecast
information for current and forecast weather conditions. The Surface Analysis
forecast shows frontal lines indicating weather fronts and the direction they are
moving. High and Low pressure centers are noted with a large H or L. A Cold
Front is a front where cold air replaces warm air. A blue line with blue triangles
will point in the direction of cold air flow. A Warm Front is where warm air
replaces cold air. A red line with red half moons will point in the direction of
the warm air flow.
