An incredible amount of rain fell last Thursday evening/Friday morning across El Paso County, especially on the southeast side of Colorado Springs. Check out the rainfall graphic below, courtesy of the National Weather Service in Pueblo:
Three factors led to this rain event: ample moisture, an upper level disturbance, and upslope winds at the surface. These factors contributed to the "training" of showers and thunderstorms, meaning cells persistently moved over areas that had already seen heavy rain. The Colorado Springs Airport bore the brunt of this effect, reporting 4.97" over the two days. It seems like we couldn't buy a raindrop at the airport all summer. And here we practically made up for it in the blink of an eye. A deluge like this is pretty rare for Colorado Springs...in fact, it may be YEARS before we see experience anything like it again.
