Parting Shots From Popup Cell

Daylight was waning fast as the structure of the severe-warned storm cell located in northwest Illinois continued to expand on the evening of Thursday, August 18, 2016. Knowing that my photography opportunities were fading here in Delaware County, Iowa, I decided to head back to Cedar Rapids. While southbound on Highway 13, I captured the four images posted today. Above, my vehicle was located about 1.3 miles north of 275th Street (D42) at 7:36 pm CDT. The storm was moving away and about 73 miles to the east at this time, near Stockton, Illinois. The small bright area of the overshooting top can still be seen.

A more zoomed-in view a minute later.

7:44 pm. Looking east from 325th Street at Highway 13, about 2 miles south of Ryan, Iowa.

7:46 pm. With my vehicle as a foreground element. Because of distance or a decrease in severity, the overshooting top has now disappeared from the structure. Note the thin inflow cloud at right in all four images. Nikon D7200 DSLR camera.
