Rick Bly, NWS observer in Breckenridge, said July brought above-average precipitation to the area, with 2.54 inches having fallen by early Friday afternoon. The average is 2.32 inches. In the past year, there were only three months of above-average precipitation. April was 14 percent above normal and October 2009 was also above normal. “We’ve had a concerning lack of moisture,” Bly said. “So it’s good that we’re getting caught up a little bit here.”[…]
Bly said that on July 29, Breckenridge received 1.13 inches of rain — a rare occurrence. “I’ve been keeping records for about 35 years, and I think over an inch in precipitation (has fallen) in less than 24 hours less than a dozen times in all those years,” he said.
