Summary:
A large-scale trough entered the west coast of North America yesterday, increasing moisture across Colorado. The moisture transport came from the west, rather than the southwest, signaling that the monsoon is waning quickly. Favorable dynamics associated with the trough brought widespread light-to-moderate rainfall across the High Country yesterday, mainly along and west of the Continental Divide. Low-level dry air kept heavy rain out of the forecast, so no flash flooding was observed. From CoCoRaHS observers, the following counties were the “big winners” regarding rainfall reports:
Gunnison County: 0.65 inches
Mesa County: 0.48 inches
Garfield County: 0.36 inches
Moffat County: 0.28 inches
Montrose and Delta County: 0.26 inches
Eagle County: 0.25 inches
