A slow moving front will be the focus area for heavy to excessive rainfall and a threat for flash/urban flooding across the northern Gulf Coast and Southeast U.S. through this weekend.

Three wet microbursts were identified within a squall line that moved through the Sioux Falls area during the early morning hours of June 11th. A microburst is essentially an area of strong surface winds which are accelerated to the ground from aloft in a thunderstorm, and a wet microburst is that which is accompanied by falling precipitation. For a more extensive review of the damage, please see our damage survey. The following image displays the locations damage across the city, as well as the tracks of the three microbursts, represented by the orange, purple, and red rings. The orange and purple tracks likely extended further into central portions of the city, but cannot be identified due to limited radar coverage.
These reports are summarized in this table, which lists the damage sustained, the estimated wind speed (if available), and the latitude and longitude of the damage.
