Severe weather situational awareness system and related methods

A severe weather detection and warning method may include collecting atmospheric sounding data from at least one satellite atmospheric sounding device corresponding to a grid of localized regions, with the atmospheric sounding data including geospatial location and elevation components. The method may further include collecting weather radar data for the grid of localized regions from at least one radar station, determining a location and direction of travel of at least one moisture system based upon the weather radar data, and determining respective atmospheric instability levels for the localized regions based upon the atmospheric sounding data. The method may also include determining when the direction of travel of the at least one moisture system is approaching a given localized region having an atmospheric instability level above an instability threshold, and generating a severe weather warning indication based thereon.
