The month of July continued the recent trend of cool, damp weather. By the time it was said and done though, while temperatures overall were below average, precipitation fell short of normal.
Temperatures were at or above normal for the first few days allowing for a pleasant Independence Day.
The day after, however, a monsoonal weather pattern cooled things down and brought most of the month’s moisture over the following 10 days.
Ridging then built and we settled into a relatively normal period for the final two weeks although precipitation became scarcer.
Thornton saw an average temperature for July 2015 of 71.2 degrees. This was a good bit below the long term Denver average of 74.2 degrees. Out at Denver International Airport where the Mile High City’s official measurements are taken, the average for the month was 72.8 degrees.
Our temperatures ranged from a high of 96.1 degrees on the 27th down to a low of 53 degrees on the 11th. Denver saw a maximum of 97 degrees and a minimum of 52 degrees.
Denver averages 2.16 inches of precipitation during July. Thornton fell a bit short of that mark recording 1.76 inches. At the airport, only 1.06 inches was recorded.
