Using XM WX Weather and Audio
Understanding Fronts
The Fronts show lines indicating the leading edge of an air mass. This feature also shows pressure
centers.
Indicates a low-pressure center. A low-pressure center is an area where the measured
pressure is lowest relative to the surrounding area. Moving away from a low-
pressure center in any horizontal direction results in increased pressure. Winds flow
counterclockwise around low-pressure centers in North America.
Indicates a high-pressure center. A high-pressure center is an area where the measured
pressure is highest relative to the surrounding area. Moving away from a high-pressure
center in any horizontal direction results in decreased pressure. Winds flow clockwise
around high-pressure centers in North America.
Understanding City Forecasts
City forecasts appear as standard weather symbols. The forecast is viewed in 12-hour increments for
