August 2019 weather recap: Thornton experiences very warm, very dry month

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.

Thornton’s September preview: One of our more pleasant, calm months usually

Following an August that was unseasonably warm and dry, we find ourselves heading into September hoping for relief.  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.

Get a complete look at September’s weather and more details as to what we can expect this year here.

Records tumble as Denver hits 100 degrees today

Record High Temperatures

Yesterday, Denver set a record high temperature for the month of September. We followed that up by breaking the day-old record and also breaking two others.

The high temperature today in the Mile High City, as measured at Denver International Airport, topped out at 100 degrees.

This easily tops the record high temperature for September 2 of 95 degrees set in 1983. Further, this is the hottest temperature ever recorded in Denver in the month of September, topping yesterday’s record-setting 98 degrees.

Lastly, this is the latest a 100 degree or higher reading has been recorded in Denver. The previous latest was August 16, 2002.

Thornton actually was a touch warmer today with a high of 101 degrees.

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 September 2, 2019

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.

Denver sets record high for September 1 and for the entire month of September

Record High TemperaturesIt was a hot one indeed! We knew the potential was there for record-breaking heat this Labor Day weekend and indeed it came to fruition.

Denver’s high temperature today, as measured at DIA, topped out at 98 degrees at 1:17pm.

This not only set a new record high temperature for September 1 but it also marks the warmest temperature ever recorded in the Mile High City in the month September.

The previous record high for today, and for September, was 97 degrees set in 1995.

Here in Thornton, we managed to actually be hotter than DIA, topping out at 101 degrees.

If that wasn’t hot enough for you, wait till tomorrow as we may see today’s record setting readings broken.

Denver ties record high temperature for August 19

Record High Temperatures

As expected, temperatures across the Front Range climbed toward record-setting territory today and the Mile High City tied the 21 year old record high.

As measured at Denver International Airport, Denver’s high temperature today hit 99 degrees. That tied the old record high for the date set in 1998.

Here in Thornton, we matched that 99 degree reading at 1:49pm.

July 2019 weather recap: Thornton comes in a bit hotter than normal with average precipitation

Following a cool June, summer heated up in earnest in July. Temperatures warmed as they always do in July and were a bit warmer than normal and were coupled with typical PM thunderstorms.

The first eight days of the month saw a few warmer than normal readings but nothing too extraordinary. We did also enjoy three days with some nice, wetting thunderstorms.

After that, the heat kicked on and we registered nine straight days of 90+ degree readings from the 11th to the 18th. The last two days of the period also saw our first two 100+ degree days.

We then had a bit of a break from the heat for a few days before stringing together another nine 90+ degree readings.

Thornton’s overall average temperature for the month came in at 74.7 degrees. This was above the long term Denver average of 74.2 degrees for July. Out at DIA where Denver’s official measurements are taken, it was a good bit warmer with an average of 75.7 degrees.

Thornton’s highs ranged from a maximum of 101 degrees on the 19th down to a low of 54.5 degrees on the 9th. Denver also saw its maximum of 101 degrees on the same day and its coolest reading of 52 degrees on the 10th.

Denver tied record high temperatures on the 18th and 19th of 99 degrees and 101 degrees (set in 1998 and 2005 respectively).

In terms of precipitation, Thornton saw 2.18 inches fall in its bucket while Denver notched a bit more at 2.42 inches. The Denver average for July is 2.16 inches.

Thornton’s August 2019 preview: Temperatures begin to cool, fewer storms intrude

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.

Find out more about what lies ahead with Thornton’s August weather here.

Colorado offers outdoor opportunities unlike any other state and while the summer heat settles in, photos of the amazing scenes across our state provide a view into why we love it here so much.

The weather this time of year has a pretty standard pattern of quickly warming temperatures followed by afternoon thunderstorms that can cool things down.  These storms sometimes provide a good bit of ‘excitement’ and are a prime photo subject.
