From The Longmont Times-Call (Charlie Brennan):
Boulder County has gone entirely yellow.
On the map of the U.S. Drought Monitor, that’s not a good thing, as it equates to “abnormally dry.”
As lawns and grasslands across the Front Range plunge further and further into such aridity that green is a faint memory, a swath of yellow — one step short of “moderate drought” — now sweeps down on the U.S. Department of Agriculture’s map from north-central Colorado toward the southeast, enveloping all of the thirsty Boulder-Denver metro area.
As recently as Aug. 2, much of Boulder County was already in the “abnormally dry” classification, but a sliver of east Boulder County had not yet merited that designation. No more.
“It has indeed been a dry summer for Boulder (and for Denver and Fort Collins),” meteorologist Matt Kelsch said in an email…
Typically, Boulder County’s precipitation for June, July and the first half August is 2.04 inches, 1.91 inches and 0.87 inches, respectively, for a total of 4.82 inches in that 2 ½-month stretch.
In the particularly parched summer of 2016, the precipitation recorded for that period was a 2.37 in June, then a mere 0.61 for July and 0.24 so far in August. That’s a total of 3.22, or, about two-thirds of average.
“It’s even worse when you consider that nearly half of June’s rain fell on June 1st,” Kelsch said. “Since June 1st, there has not been a single day that produced at least a half-inch of rain.”
