Current Surface Map
The data on this site are provided from the National Weather Service via the NOAAPORT satellite data service. All the images are generated using the Weather Processor (WXP)analysis package which is available from Unisys.
Weather Symbols

Frontal Location Plot
Frontal locations are denoted by bold lines in the following colors:
High and Low pressure systems are plotted with H and L and the associated pressure in millibars is displayed below the letter.

NOTE: Frontal data are only available every 3 hours so fronts may not exactly match the weather conditions. A label at the bottom left denotes what time the fronts are valid.

Pressure/Isobar Contours

The pressure contours (or isobars) are plotted as blue lines every 4 millibars and indicate positioning and extent of various pressure systems.

Surface Data Plot

The surface data plot gives the following information:
