It may take 30 seconds for the initial data to load
If you keep getting 0 UTC analyses by accident...

Latest version is 12-February-2008: Op20 data are now read from grib2 files. (Unfortunately, this is slower than reading from the old grib files.) See change details (in another window) for more information. (To get the new code, restart Internet Explorer, or for Firefox/Mozilla/Netscape, hold down the shift key and click reload.)

The new URL for this page is http://rucsoundings.noaa.gov/plot_soundings.cgi?...
The new URL for non-java soundings is http://rucsoundings.noaa.gov/gifs/
(The old URL's will continue to work for the forseeable future.)

Latest Bak40 analysis is valid at 10:00 UTC.
Latest Op40 analysis is valid at 10:00 UTC.

For information on interpreting these soundings, please see the following:
  		• The NWS Publication The Front from Feb 2004. (The web site has been updated a bit from what is shown in the article, but this is an excellent reference for pilots nonetheless.)
  		• Tutorial on upper air polot from UNISYS
  		• Tutorial from Texas A & M

    (If the display does not work for you, you can still access the old version for a while, but let me (Bill.Moninger@noaa.gov) know so I can fix the problem.)
