Mauna Kea Data:

• CSO weather log - since UT 0:00 (or since the last antenna computer reboot), time is UT
  
• Tau now (brown cow).
  
• Tau plots.
  
• UKIRT weather data - if you leave this up it will update by itself (time is HST) - at JACH
  
• JCMT weather data, latest reading: at JACH (also self-updating) or alternately at CSO, time is HST
  
• JCMT weather log - since midnight, time is HST

Other Data and Satellite images for Hawaii:

• GOES 10 water vapor image (8km resolution)
  
• Hawaii GOES-10 IR image (4km resolution)
  
• Hawaii GOES-10 12 micron image (4km resolution)
  
• Hawaii GOES-10 visual image (1km resolution)
  

From NOAA Environmental Modeling Center:

• Hawaii Upper Air (12km resolution) 84-hour Forecast
  The "700mb Height and RH" tab, showing the height (in meters) of the 700mb surface and the Relative Humidity, is probably of most interests in prognosticating the summit weather.
