Severe Weather Sunday Night and 72 Hour Rainfall Reports

Synopsis:   An upper level disturbance tracking across the northern plains combined with a moist and unstable atmosphere to produce scattered strong to severe thunderstorms on Sunday night into Monday morning.  The hardest hit areas generally occurred from McPherson County eastward into northern Brown and Marshall Counties where sporadic tree and property damage occurred.  Eureka saw some of the worst damage with more numerous trees and branches down.  Several outbuildings were heavily damaged or destroyed, and several residences also sustained minor to moderate roof and siding damage.  The strongest wind speeds in and around Eureka were estimated to be 70 to 80 mph.  For a listing of severe weather reports, click HERE.   

In addition to the severe weather, another round of heavy rainfall also impacted portions of northwestern and north-central South Dakota.  Combined with the rainfall on Friday and Saturday, the 72 hour precipitation amounts across the NWS Aberdeen forecast area generally ranged from 2 to 4 inches across Corson County, to just a few hundredths across far east-central South Dakota including the I-29 corridor (see graphic below).  A tabular listing of received reports is also listed below.
