SURFACE PRESSURE

This feature displays pressure isobars and pressure centers. The isobars connect
points of equal pressure. Pressure readings can help determine weather and wind
conditions. High pressure areas are generally associated with fair weather. Low
pressure areas are generally associated with clouds and the chance of precipitation.
Isobars that are packed closely together show a strong pressure gradient. Strong
gradients are associated with areas of stronger winds. Pressure units can be
displayed in Millibars (mb) and Inches of Mercury (in).
