Fronts

The Fronts feature displays the lines indicating the leading edge of an air mass that is replacing another. This feature also displays pressure centers. Pressure centers are

represented by a large Red "L" for low pressure centers or a large Blue "H" for high pressure centers. Pressure centers represent an area where pressure is measured to

be either the highest or lowest relative to the surrounding area.

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. Similar

to a Low 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.
