Hefty Line In Lean Conditions

These lines of storms, though not severe, were vigorous enough to produce billowing cumulus on Friday afternoon, July 26, 2013. The line of cumulus stretched for nearly 225 miles (bottom radar image) from southeast Iowa to south-central Wisconsin. The curious thing about this was their formation in not-so-ideal conditions. Temperature was 75 degrees F, dew point 56 degrees and relative humidity 52%--more like early autumn. The top image looks east around 3:26 PM along County Home Road about .8-mile east of Highway 13 and about 3.6 miles west of the town of Whitier, Iowa. The middle image also looks east, around 3:36 PM on Prairie Chapel Road, about .4-mile east of County Road X20 (Whitier Road), and about one mile northeast of Whitier in eastern Linn County.
