With the first full month of fall here, October usually brings one of the quietest weather months in the Denver area with plenty of mild, sunny days and clear, cool nights.
October is historically the second sunniest month and conditions are generally calm.
However we also will usually see our first taste of winter during the month with the first freeze and first snowfall of the season.
Temperatures as well will start to drop and by the end of the month the average nighttime lows are below freezing.

Only five days into the month of September and the heat has records falling left and right.
Today, at 2:05pm, the temperature at Denver International Airport where Denver’s official readings are taken, reached 98 degrees. This topped the previous record high for September 5 of 97 degrees set in 2013 and 1899.
Here in Thornton we were actually warmer with a high of 99 degrees coming at 2:58pm.
Today’s record comes on the heels of record highs on the 1st and the 2nd of the month.
The 100 degree high of the 2nd was also the latest 100 degree reading ever recorded in Denver and also the warmest September temperature on record.
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.

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.

There is little doubt that looking back on the month the most notable feature was the cool, sometimes chilly, temperatures. Denver in fact saw one of its coldest on record. Precipitation for Thornton lagged but Denver itself was quite wet.
A seemingly endless series of storm systems impacted the state through the month. Overall, the first week was seasonal and dry. Temperatures then cooled for a couple of days and delivered us a light shot of snow. We rebounded with a series of 80 degree days from the 13th to the 16 before once again chilling out.
From the 18th to the 23rd, temperatures remained below normal and on the 21st we received a respectable 3.3 inches of snow. Temperatures during that period dropped to below freezing three times.
The balance of the month continued the roller coaster with a few mild days followed by cooler ones.
Thornton’s overall average monthly temperature for May came in at 51.9 degrees. This made it the coldest May since ThorntonWeather.com came online 13 years ago.
Out at DIA where Denver’s official measurements are taken, the month was comparable with a 51.6 degree average. That made May 2019 the seventh coldest May on record and the coldest since 1995.
Highs ranged in Thornton from a maximum of 89 degrees on the 15th down to a lowest reading of 29.8 degrees on the 22nd. Denver’s highest reading of 83 degrees and its coldest of 30 degrees came on the same dates.
Three temperature records were officially set in Denver. The record low for May 21st of 31 degrees was tied. Also on that day, a record low maximum of 39 degrees was set. The old record was 40 degrees set in 1891. Lastly, the low on the 22nd of 30 degrees broke the record low reading for the date of 32 degrees set in 1930.
In terms of precipitation, Denver averages 2.12 inches during the month. Thornton came close to matching that with 2.03 inches. Out at the airport, it was wetter with 3.23 inches being recorded.
Thornton saw a total of 4.1 inches of snow for the month while Denver saw a bit less at 3.9 inches. Both were well above the May average of 1.1 inches.

The month of April had the usual, inconsistent weather conditions we expect from the month. Thornton enjoyed everything from spring-like days with mild temperatures to a healthy round of snow and cold.
The month started out mild with seven of the first nine days of the month seeing above normal temperatures and pleasant conditions. A cold front and storm system moved in on the 10th though and brought about significant changes for a few days and our first snow of the month.
Warmer weather returned though and on the 20th we recorded our first 80 degree day of the year. Showers and thunderstorms on the 21st brought some much-needed rain then we dried back out for the next six days. We saw a couple more 80+ degree days then the final two days chilled things out and delivered a bit more snow.
Thornton’s overall average temperature for the month came in at 49.6 degrees. This was a good bit above Denver’s long-term April average of 47.4 degrees. Out at DIA where the Mile High City’s official measurements are kept, the average temperature was similar with 49.1 degrees.
Temperatures in Thornton ranged from a high of 81.4 degrees on the 26th down to a low of 17.5 degrees on the 11th. Denver saw a high reading of 80 degrees on the 20th and a low of 17 on the 11th.
In terms of precipitation, Denver averages 1.71 inches during April. Both Thornton and Denver fell short of that mark with 0.78 inches and 1.25 inches in their rain buckets respectively.
Snowfall in Thornton was respectable with 8.1 inches of the white stuff. Denver was well short of that with 3.5 inches. April averages 6.8 inches so while Thornton was above that, Denver was below.

Thornton, Colorado seasonal snowfall totals as of April 11, 2019. Click for larger image. (ThorntonWeather.com)
Thornton hasn’t had any truly big time snows this year but we have managed a number of respectable ones and that shows in our seasonal snow totals.
As of today, Thornton has received 49.1 inches of snow for the season. That is just slightly below our running 13 year seasonal average of 53.1 inches.
As for Denver, officially, the Mile High City has recorded 43.2 inches thus far this season as measured at DIA. The all-time seasonal average snowfall for Denver is 57.1 inches (55.3 inches 30 year average) so there is still ground to make up there to get near average.
With half of April and all of May to go, there’s still plenty of time to add to those numbers.
In case you were wondering… The average date of Denver’s last snowfall is April 27th. The latest? June 12, 1947 when a trace was recorded. The latest measurable snowfall was 0.4 inches on June 1, 2919.
The unstable, cold and wet weather that marked February continued right on into March. Once again, we saw temperatures well below normal and a good bit more than average precipitation.
While the first day of the month started things off relatively nicely, the second brought the first bout of cold. Temperatures plummeted with highs on the third only in the single digits and nighttime low temperatures below zero on the 3rd and 4th. This was coupled with a nice shot of 3.4 inches of snow on the 3rd.
We then slowly warmed up and enjoyed near normal temperatures for a brief period of time. This changed quickly and significantly with the arrival of a blizzard on the 13th. Powerful winds coupled with snow shut down schools, businesses, highways and Denver International Airport.
Calmer, drier weather then took hold for much of the rest of the month although most days continued to see temperatures below normal. The 26th and 27th did offer up our first days of 70 degree or warmer temperatures.
The month closed out with another shot of cold on the 29th and 30th and a light bit of snow.
Thornton’s overall average temperature for the month of March was 35.1 degrees. Out at Denver International Airport here the Mile High City’s official measurements are taken, they matched our temperature with an average of 35.1 degrees as well. Both were well below the historical average March temperature for Denver of 40.4 degrees.
Temperatures in Thornton ranged from a maximum reading of 74.9 degrees on the 27th down to a low of -5.0 degrees on the morning of the 4th. Denver saw its maximum of 73 degrees on the 27th and its minimum of -6 degrees on the 3rd.
Denver set a record low maximum for March 3rd when the temperature only reached a high of 6 degrees. The old record was 14 degrees set in 1978. Additionally, a low temperature reading of -3 degrees on the 4th tied the record low for the date also set in 1960 and 1978.
In terms of precipitation, Thornton recorded 1.19 inches in our bucket while Denver bested us with 1.39 inches. Both were above the long term Denver average for the month of March of 0.92 inches.
Denver’s 0.64 inches of liquid precipitation on the 13th set a daily record, easily besting the old record of 0.43 inches (1926) for the date.
Denver averages 10.7 inches of snow during the month of March. Thornton and Denver beat the average with measurements of 12.2 inches and 12.9 inches respectively.

The month of March in Denver is usually one that is welcomed heartily by residents. We begin to shake off the cold of winter with warmer temperatures and calmer conditions. That does not mean we are done with snow and cold by any means.
March usually offers healthy snowfall giving us an opportunity to add to our seasonal totals. While there is good snow potential in March, the month also typically brings much warmer temperatures.
March is historically Denver’s snowiest month and brings about 20% of our annual snowfall. Heavy, wet spring snow storms can oftentimes bring the entire month’s snowfall total in one monstrous snow.
We also start the transition to spring and severe weather season and the month typically brings our first thunderstorms of the year. Temperatures climb throughout the month and by the end our average daytime highs are near 60 degrees.
February in Colorado typically brings to an end an extended period when average temperatures are at their lowest. Winter begins to loosen its grip and temperatures get warmer but precipitation is not a particularly common event during the month.
Thus far our snow season has been relatively dismal with the seasonal total in Thornton more than 10 inches below average. In the high country, the snowpack is not faring much better. February is only our sixth snowiest month so we may not see much snowfall for the balance of the month.
