Following on an August that saw seasonal temperatures but little precipitation, some are certainly hoping for a bit of the wet stuff in September. The month can bring plenty of rain and even our first snow of the season but more often than not, it is one of the most pleasant along the Colorado Front Range.
As temperatures start to drop, September usually reminds us that summer is at an end and fall is now here. Sunshine is predominant though as the month actually has the highest percentage of sun out of any month. Sunny days and clear, cool nights are the standard weather pattern for the month.
The month can bring extremes however. We will of course forever remember 2013’s devastating floods brought on by record-setting rain. Longtime residents might remember September 1971 which brought over 17 inches of snowfall.
Somewhat of a mixed bag for Thornton’s weather in August. While we enjoyed temperatures near normal without too many extremes, precipitation was lacking considerably from what we expect during the month.
The month started out toward the cool side but with days of above normal temps interspersed. For the first few weeks it appeared we would end up a good bit cooler than normal but then the heat returned for much of the last week driving up average temperatures.
Precipitation was quite disappointing with only a couple decent rainfalls during the month and a few minimal events.
Probably the most notable thing for the month was the relatively persistent haze from smoke from wildfires to our west. While it made for pretty sunrises and sunsets, it obscured our normally beautiful blue skies.
Thornton finished the month with an average temperature of 70.4 degrees. That is more than two degrees cooler than Denver’s long term August average of 72.5 degrees. As is the norm, Denver’s official measurement came in a good bit warmer with an average of 72.4 degrees.
Our highs ranged from a maximum of 94.9 degrees on the 4th of the month down to a low of 47 degrees on the morning of the 20th. Denver matched our maximum on the same date and saw a low of 46 degrees on the 20th which also tied the record low for the date.
The month saw a paltry 0.52 inches fall in Thornton’s rain bucket. Denver actually fared better with 0.93 inches. Both measurements however fell short of the August average of 1.69 inches.

Black and white of a scene in Thornton. (LE Worley)
As the calendar turns to August, the summertime heat begins to fade and that makes it easier to get out and enjoy all of the outdoor activities Colorado has to offer. From a walk in a park to afternoon thunderstorms to an abundance of wildlife, photo opportunities abound as is seen in our slideshow.
Our monsoon season typically arrives about now and that means better chances for moisture. However with limited instability, the intensity of storms are more sedate. That doesn’t mean however that the weather is any less photographic.
Slideshow updated August 31, 2018
By the end of the month some of our seasonal feathered friends will be looking to leave the state giving our last chance to see them till spring. Larger mammals are gearing up for the rut (mating season) and that can make for some intense scenes.
Showcasing images captured by ThorntonWeather.com readers as well as some of our own, our monthly slideshow covers the entire gamut of weather and nature related imagery. Sunsets, sunrises, wildlife and of course every type of weather condition are vividly depicted.

August 26 to September 1: This week in Denver weather history
Significant events on Denver’s weather history calendar get a bit less numerous as we enter what is historically a relatively quiet period of the year. That isn’t to say however that major weather events can’t occur. Our look back at this week in Denver weather history includes a massive hail storm in 1944, many events in which lightning injured people and the warmest temperature ever recorded in September.
From the National Weather Service:
19-30
In 1875…grasshoppers appeared in great numbers at 10:00 am on the 19th. Thousands landed on the ground. The streets were literally covered with them. Swarms of grasshoppers were seen on each day. All gardens in the city were devastated…and in the countryside the grasshoppers were very destructive to ripened grain. On the 30th the grasshoppers were so numerous as to almost darken the sun.
24-26
In 1910…the lowest temperature ever recorded in August…40 degrees…occurred on each of these days and on August 22… 1904. The unusually cold weather for so early in the season brought sub-freezing minimum temperatures to much of the Colorado northeastern plains.
26
In 1944…one of the most destructive hailstorms in the city in a decade caused damage estimated at nearly one million dollars. The storm occurred within a period of 10 to 30 minutes…between 2:00 pm and 3:00 pm. The hail varied in size from very small to as large as 1 1/2 inches in diameter. Hail covered the ground to a depth of 5 to 6 inches in some sections of the city. Several people were cut by broken glass. The hail and heavy rain flooded underpasses to a depth of 6 feet…and the occupants of stalled autos had to be rescued. Sewers were unable to handle the sudden amount of water and water backed up and flooded a number of basements. A few first floors of buildings were flooded. The water department had a busy time replacing manhole covers that had been displaced by the water pressure. Trees were stripped…one was severely broken…and telephone lines were downed. Roofs…windows… automobiles…awnings…and gardens were severely damaged. Flowers and gardens in some sections of the city were a total loss. Greenhouses were extensively broken with an estimated 20 carloads of glass shattered. Vegetable and truck crops in and around the city were severely shredded. The next day the American Red Cross was designated by the war agency to grant any and all priorities needed to obtain materials and supplies to replace and repair the damage. In downtown Denver…the thunderstorm produced 0.95 inch of rain and heavy hail along with sustained northwest winds to 25 mph.
In 1961…strong winds blew in the walls of a warehouse under construction in Denver. Two workmen suffered a fractured foot and body bruises.
In 2014…two men in central Denver were struck by lightning as they sat under a tree to avoid a heavy downpour. One of the men was unconscious and had no pulse when emergency responders arrived. He was immediately taken to Denver Health was listed in critical condition. The other victim suffered less severe injuries. He was treated at the scene and hospitalized…then released a few hours later.
26-27
In 1980…two heavy thunderstorms hit Arvada and Westminster… Dumping up to 1.50 inches of rain in less than an hour. At least two streets were washed out and a number of homes and cars were damaged when a creek flooded. Three homes in Arvada sustained minor lightning damage.
27
In 1910…a thunderstorm produced south winds sustained to 40 mph.
In 1961…strong thunderstorm winds and heavy rain occurred at 79th and federal blvd. In Westminster. The strong winds blew the roofs off lumber sheds onto parked cars.
In 1967…a young woman was killed by lightning while horseback riding in the suburbs just west of Denver. Her horse died several hours after the incident. A young man and another young woman were also knocked from their horses by the impact of the lightning and required hospitalization.
In 1991…heavy thunderstorm rainfall totaled 0.91 inch at Stapleton International Airport…where 1/4 inch diameter hail was measured.
In 1996…localized street flooding occurred in the Fort Lupton area when 2 to 3 inches of rain fell in 45 minutes. The roof of a community college began leaking…which caused damage to ceiling tiles. The roof was under repair from hail damage which had occurred earlier in the summer. A weak tornado (f0) was sighted near Fort Lupton. No damage was reported.
In 1999…a slow moving thunderstorm dumped 5 inches of rain in 2 hours near Dacono. A severe thunderstorm produced 3/4 inch diameter hail in Castle Rock.
In 2002…severe thunderstorms spread large hail over metro Denver. Hail as large as 2 inches in diameter fell in Jefferson County 5 to 11 miles northwest of Golden. Other large hail reports included: 1 1/2 inches near Golden and in Lakewood; 1 1/4 inches in Nederland; 1 inch hail near Elizabeth…Louviers…Rollinsville…and Blackhawk; 7/8 inch hail near Acequia in Douglas County. A thunderstorm produced a trace of rain and a microburst wind gust to 52 mph at Denver International Airport.
In 2003…lightning struck a house and sparked a fire in Arvada. Damage to the roof and ceiling was extensive.
In 2005…lightning struck an unoccupied home in Parker. The resulting fire damaged the roof…attic…and second floor bedroom. Damage was estimated at 15 thousand dollars.

Close by…heavy thunderstorm rains caused gullies…irrigation ditches…and small streams to overflow their banks near the intersection of 120th Avenue and Riverdale Road. Flood waters 1 to 2 feet deep covered the river bottom land along the South Platte River. However…no structures were threatened by the flood waters.
In 1999…heavy rain…up to 5 inches in two hours…caused east tollgate creek to jump its banks. The bike path adjacent to the creek was underwater at several locations.

If you were thinking you were feeling fall in the air the last day or two you had good reason. Temperatures this morning almost felt chilly and Denver tied the record low temperature for the date.
At 6:25am this morning, the mercury at Denver International Airport where the Mile High City’s official records are taken dipped to 46 degrees. This tied the record low temperature for August 20 last set in 1939.
Here in Thornton we were just a touch warmer with a low of 47 degrees. That was our second chilliest temperature since May 21.

The silence from the Thornton PD has been deafening. As other Denver metro area police departments posted their lip sync challenge entry, we heard nothing from the local men and women in blue. That changed today.
Set to the song “Danger Zone” by Kenny Loggins and made famous in the movie Top Gun, the Thornton Police Department brings it all from cars to motorcycles to yes, even planes.
All in all, we have to say the video is worth the wait and probably the best we have seen from any local agency. Of course we are residents of Thornton and Navy veterans so we might be biased. 😉

As summer vacations wind down and families prepare to send their kids back to school in August, Colorado weather also starts to settle down. The chances for severe weather decrease markedly during August and by the end of the month daytime temperatures are dropping quite a bit as well.
The month of July was somewhat a tale of two months in one. The first half was most notable for their unseasonably warm temperatures and relatively dry conditions. The second half saw a few days of heat but for the most part was considerably cooler and wetter.
Thornton saw an average temperature for the month of 73.5 degrees. Out at Denver International Airport where the Mile High City’s official readings are taken, the month saw an average of 75.3 degrees. Long term, the month of July sees an average of 74.2 degrees in Denver so while Thornton was cooler than that, Denver was warmer.
Thornton had its highest temperature reading of 99.9 degrees on the 19th and its coldest of 47.7 degrees on the 1st. Denver saw its warmest reading of 99 degrees on the 3rd and its coldest of 47 degrees on the 1st.
In terms of precipitation, Denver’s long term July average is 2.16 inches. Thornton easily bested that number with 3.66 inches in our rain bucket. The Mile High City fell well short with only 1.03 inches.
