The NOAA National Weather Service MicroART upper air system at Great Falls,
Montana (WMO# 72776), will be decommissioned on or about May 14, 2010, and
installation of the new Radiosonde Replacement System (RRS) will begin. No
upper air observations will be provided from this office while RRS is being
installed.
Beginning May 24, 2010, or shortly thereafter, upper air observations will be
issued using the RRS and GPS Mark IIA Sippican radiosondes.
