September outlook for Boulder

September 1, 2015 / Ben Castellani

The weather this August has been very mundane, compliments of a pesky ridge of high pressure which has held its ground across the American Southwest. As a result, August was characterized by beautiful weather, albeit hot. The monsoon plume has largely been confined to Arizona, Utah, and western parts of Colorado, keeping the Front Range relatively parched the past month. Will this trend continue into September? Read on as we examine Boulder’s climatology and consider the current state of the atmosphere to give our outlook for next month.

However, 90s will make an reappearance at some point. Read on to find out when!
