Did you feel a very slight chill in the air this morning? It was very pleasantly cool and in fact, record-tying.
As measured at Denver International Airport, the city’s official low temperature dipped to 47 degrees. This breaks the record low for the date set in 1978.
Here in Thornton, we weren’t quite as cool with a low of 50 degrees. That was our coldest August 5th reading in the past 20 years that Thornton Weather has been operating. The previous low for the date was 53.9 degrees in 2015.
Editor’s note: This story originally reported Denver’s low as 48 degrees, per the National Weather Service. They then revised the number to 47 degrees and the story was updated accordingly.
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 heat has been on throughout the summer and continued today as Denver set another record high.
As measured at Denver International Airport, the Mile High City’s official high temperature today came in at 102 degrees. That breaks the old record high for the date of 100 degrees set in 1878.
Here in Thornton, we bested Denver slightly with a high of 103 degrees.
Following on a record setting high, the nighttime brought little relief and set another warm weather record.
As measured at Denver International Airport, the Mile High City’s low temperature for July 27 was only 74 degrees. This breaks the previous record high minimum for the date of 72 degrees set in 1931.
Notably, this reading is also the third warmest minimum temperature ever recorded in Denver. The warmest is 77 degrees recorded on July 3, 1881.
Here in Thornton, we did not stay near as warm at night with a low of 64.2 degrees.
No rest from the summer heat for the Mile High City as Denver sets a record high for the second day in a row.

The month of June typically sees springtime severe weather reach its height of activity in northeastern Colorado.
This affords the opportunity to capture extraordinary images of amazing weather phenomena from monstrous supercell thunderstorms to heavy rain, hail and even tornadoes.
Slideshow updated June 17, 2026
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. June brings some very dynamic weather and the photos are a great way to see the stunning variety.

Our monthly photo slideshow is going to feature images that we have taken but more importantly images that you have captured. The photos can be of anything even remotely weather-related.
Landscapes, current conditions, wildlife, pets, kids. Whimsical, newsy, artsy. Taken at the zoo, some other area attraction, a local park, a national park or your backyard. You name it, we want to see and share it!
Images can be taken in Thornton, Denver or anywhere across the extraordinary Centennial State. We’ll even take some from out of state if we can tie it to Colorado somehow.
We’ll keep the criteria very open to interpretation with just about any image eligible to be shown in our slideshows.
What do you win for having your image in our slideshow? We are just a ‘mom and pop’ outfit and make no money from our site so we really don’t have the means to provide prizes.

The City of Thornton has announced that it has replaced the old CodeRed emergency alert system with a new one called “ThorntonReady Emergency Alerts.” We highly recommend all residents sign up for the new system immediately.
With the system you can choose exactly which types of events you want to be notified about – civic alerts, weather advisories, weather warnings, etc. Additionally, you control how you want to be notified whether by phone call, text, email or all of them.
We found that they wanted to alert users with an entire gamut of alerts, many which don’t really warrant a middle-of-the-night phone call. However, the ability to be notified about the more common advisories is a nice touch and helps to keep you informed.
For us, we opted out of calls for advisories although being geeks we don’t mind the texts or emails. For calls, we chose only tornado warnings. If you are in an area where appropriate, we would suggest also opting in for calls for flash flood warnings. See attached screenshot of our choices.
Should you desire, you can also add information about your household that could be seen my emergency responders should an emergency arise. These include other members of the household, special health requirements, pets and more.
We chose not to add the personal information at this time as we are somewhat suspicious of what that information could be used for and who it may be shared with beyond first responders.
This service is crucial to ensuing you are notified about dangerous conditions at your home. Please do sign up.
Extreme weather can occur during in month in Colorado we well know. June however is when traditional spring severe weather arrives in the state oftentimes with hail, damaging wind and tornadoes.
Over 40 percent of the tornadoes that occur in Colorado happen during the month of June. Far more common are thunderstorms with hail and wind, each responsible for extensive damage each year.
While severe weather is common, so too are brilliantly sunny and mild days as we close out spring and enter summer. If you are looking for cold, it isn’t likely but it is possible as the Denver area has seen freezing temperatures and yes, even snow, during the month.
