According to the American Meteorological Society Glossary of Meteorology, a heat burst is a "localized, sudden increase in surface temperature associated with a thunderstorm, shower, or mesoscale convective system, often accompanied by extreme drying."
Indeed, several Mesonet weather stations just northwest of Mobridge, SD (including the Mahto SDSU and McLaughlin+Trail City RWIS stations) recorded sudden increases in temperature and decreases in humidity, along with spikes in wind gusts from 10 pm Friday to 1 am Saturday morning. Notably, the Mahto station rose ~15 degrees in 20 minutes peaking at 96 degrees at 11 pm, and gusted to 62 mph just before at 10:55 pm. Showers falling into the right environment led to this fairly rare phenomenon. See the slides below for more details.
