The episode as NWS GLD wrote it up.
During the late afternoon a severe thunderstorm moved south across western Yuma county into central Kit Carson county. Near Joes estimated 80 MPH winds snapped three to four inch diameter tree branches. The high winds caused rain to be driven in between the windows and the wall into the house. Intense, heavy rainfall from the storm also led to flash flooding near the same location, where at least a foot of water was flowing over a low point in the road. In Joes the storm blew down several trees approximately twelve inches in diameter. Later the storm produced an estimated 65 MPH winds at Stratton.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
