| Episode narrativeepisode_narrative | Diurnally driven afternoon storms on Sunday, July 20th, 2025, developed within an unstable environment with CAPE values over 3000 J/kg and 40 to 45 kts of effective shear. Despite this unstable and decently sheared environment, several factors limited the severe weather potential, including weak low-level flow, a warm layer aloft, and an overall lack of forcing. This led to disorganized storms that remained below severe limits. The weak flow and low-level instability did allow for the production of a few funnel clouds in western Iowa, but these remained aloft and posed no threat to lives or property. |The primary impact from these slow-moving storms was heavy rainfall over already saturated ground from the morning's events. One storm developed directly over the Des Moines metro area and slowly drifted southward, dropping an additional 1 to 2 inches of rain on top of the 3 to 4 inches that had fallen early in the day. Drainage systems were quickly overwhelmed, producing street and building flooding in Des Moines and West Des Moines, particularly in areas near the Raccoon River. Fortunately, this flash flooding was short-lived and waters receded by the late evening. |
