The month of August usually brings respectable amounts of precipitation and by the latter part of the month, cooler temperatures. Mother Nature however had other plans last month keeping the heat on and the moisture at bay.
A dry, westerly flow was dominant for much of the month. While there were a few cool fronts and PM thunderstorms, these failed to amount to much at all and were a rarity.
Thornton saw 21 days of 90 degree or higher readings during the month. Only five days saw precipitation and three of those were in virtually negligible amounts.
Thornton’s overall average temperature for the month was 73.9 degrees. This makes it the warmest August since ThorntonWeather.com came online 13 years ago. The reading was a good ways above the long-term Denver average for the month of 72.5 degrees.
At DIA, where Denver’s official temperatures are recorded, it was even warmer with an average of 75.4 degrees. This put August 2019 into the books tying August 2007 as the warmest August ever recorded in the Mile High City.
One temperature record was set in Denver during the month when on the 19th, the high temperature topped out at 99 degrees. This topped the old record high for the date of 97 degrees.
In terms of precipitation, Denver averages 1.69 inches during the month of August. This year, Thornton recorded a paltry 0.18 inch during the month. Denver fared a bit better with 0.58 inches. Both were clearly far short of average and Thornton’s was the least amount of precipitation received in August since ThorntonWeather.com came online 13 years ago.
