+    "On Monday, September 30, a number of legacy websites were permanently removed. \

 Another option for upper air soundings is `NOAA's Ruc Soundings <https://rucsoundings.noaa.gov/>`_.
 This service allows users to download virtual soundings from numerical weather
 prediction models such as GFS, RAP, and NAM, and also real soundings from the
