It 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.
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.
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.

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.

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.

Change is of course the one constant in Denver’s weather but come July, things actually get pretty consistent.
The standard formula for a day in July is a sunny morning, clouds developing in the late morning and early afternoon. Come mid-afternoon, thunderstorms are rolling off of the foothills and into the metro area and the eastern plains. These storms do occasionally reach severe status containing hail, gusty winds and heavy downpours of rain.
Unsettled would be a good word to sum up Thornton’s weather for June 2019. We experienced a series of troughs and fronts that kept things unsettled and suppressed temperatures. That however did not translate into a great deal of precipitation.
Cooler than normal temperatures were seen across much of the month. Even the later part of June saw some days with high temperatures only in the 60s.
It wasn’t even until the 26th of the month that Denver and Thornton recorded their first 90 degree day of the year. This was in fact the fifth latest occurrence of a 90 degree day in Denver and the latest since 1982.
Thornton’s average temperature for the month came in at 65.7 degrees. This made the month the second coolest June Thornton has recorded in 13 years. Denver saw a virtually identical average of 65.6 degrees. Both readings were below the long term Denver average for June of 67.4 degrees.
Temperatures in Thornton ranged from a high of 98.5 degrees of the 28th of the month down to a low of 40.7 degrees on the morning of the 10th. Denver’s highest reading of 96 degrees came on the 29th and its coolest of 42 degrees on the 10th.
Denver averages 1.98 inches of precipitation during the month of June. This year, Thornton fell short of the mark while Denver exceeded it. Here in Thornton we tallied 1.51 inches while Denver saw 2.24 inches.

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.
