Note: "Boundary layer" above refers to the planetary boundary layer, or the layer within which the effects of friction are significant (courtesy of the NWS Glossary). The depth of this layer will vary throughout the day, typically reaching its maximum depth in the afternoon and minimum depth overnight.
A major operating system upgrade (May 19, 2025) deprecated the software necessary to create the soaring forecast. The soaring forecast will no longer be available. This tab will be removed this summer.
The soundings below show temperature (in red) and dew point (in green) at decreasing pressures (increasing heights) throughout the atmosphere. Latest Observed Sounding from Rapid City |
