2020-07-29 · near Delta Arpt, Delta, Colorado

Event narrative

A peak wind gust of 59 mph was measured by the automated weather station at the Blake Field Airport in Delta.

Wider weather episode

Light west-northwesterly flow remained over western Colorado as high pressure began to amplify over the Desert Southwest. Strong surface heating resulted in marginal instability and, when paired with residual monsoonal moisture, isolated thunderstorms developed over the higher terrain. As these cells drifted into the valleys they began to collapse and produce severe thunderstorm wind gusts across portions of west-central Colorado.
