July 9 Storm

Severe Thunderstorm Watch 348 was issued by The Storm Prediction Center (SPC) for the eastern half of Iowa on Thursday morning, July 9, 2020.

The Thunderstorm Outlook posted at 11:51 am CDT showed similar prospects, and prospects looked good for an intercept with severe weather advancing east into northeast Iowa by the early afternoon. My son-in-law accompanied me on this intercept, and we headed north on Highway 13.

1:45 pm. Sky to the north growing dark. We are northbound on Highway 38, about 1.8 miles south of Greeley, Iowa in Delaware, County.

1:49 pm. Northbound on Highway 38, about .9-mile north of Greeley in northern Delaware County.

1:49. Nearer to wind farm on Highway 38.

2:26 pm. Stationary on 10 Street, about a tenth of a mile east of C Avenue (Highway 187) at the  Fayette/Buchanan county line. Image looks northwest at approaching storm. Storm was moving right-to-left in image.

2:27 pm. Panorama looking west from spotting position on 10th Street.

2:46 pm. Shelf cloud in distance while southbound on C Avenue (Highway 187), about 2.9 miles north of US Highway 20. Storm was moving right-to-left in image and across our path.

2:47 pm. Similar capture. Nikon D7200 DSLR camera.

2:58 pm. Westbound on US Highway 20. A brief but intense rain squall made driving past this semi rig very difficult--and dangerous! The severe weather was moving on east in the north so we returned home. This image is a GoPro Hero 4 video frame capture.
