  Note Universal Time is used for these forecasts, also labeled GMT. (subtract 7 from UTC to get PDT or 8 to get PST)
  SLP stands for Sea Level Pressure.
  The 36km domain maps cover the Pacific and Western US and Canada; the 12km domain maps show more detail over the Northwest. The 4km domain maps used show the Sound in detail, now to see just the sound, scroll down to "subdomain" and pick your chart. The 4km domains are only initialized at 12 UTC, and may not be available for your desired forecast time. If the 4km domain is not available, try "subdomain" under the 12km domain.

  The forecasts are initialized at 0 or 12 UTC, (1700 or 0500 PDT), and the "Forecast Hour" is relative to that time.

  Find your desired "product." Select your desired forecast hour and plot, hit "submit selection" and see what you get! The correct PDT for the forecast is given at the top of the map.

  These maps are beautiful and informative. The download time is worth it.

• Maps of pressures and winds, and more around Washington - (If your browser does not show the data, click on a location and a box with data will appear.)

• Western Washington Surface Readings
  Map of Surface Readings From UW Atmospheric Sciences. See how the weather is changing across the area. Helps visualize the pressure gradients

  The numbers are the Farenheit temperature and the pressure in tenths of a mbar difference from 1000 mbar. So, for example, a reading of  58   166  means 58 degrees F and 1016.6 mbar pressure.

• Observations for the past 12 hours.
  The UW gives lists of observations for many stations, arranged by time. Pick "current", or a number of hours ago in their box, then hit "go."

  NOAA now has a fancier web based scheme for getting readings at specific sites.

• Current Weather at Sea-Tac from the National Weather Service. This page contains links to other NWS information.
