Following on a cooler and wetter than normal August, the month of September arrives and one can’t help but wonder if an early fall lies in wait as well. The month can bring 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 last year’s devastating floods brought on by record-setting rain. Longtime residents might remember September 1971 which brought over 17 inches of snowfall.
Periods of monsoonal moisture contributed to rain and clouds in August 2014. Coupled with the occasional cold front, the end result was a month that saw temperatures below normal and regular daily thunderstorms.
Thornton’s average temperature for the month came in at 68.2 degrees. This was more than four degrees cooler than Denver’s long term August average of 72.5 degrees. Out at Denver International Airport it was similarly cool with an average reading of 70.6 degrees.
Temperatures in Thornton ranged from a high of 94.4 degrees on the 17th down to a low of 47.6 degrees on the 30th. Only six days saw readings of 90 degrees or higher.
Denver’s warmest reading of 91 degrees occurred on the 17th and again on the 19th. Low readings of 52 degrees were seen on four days during the month. Four 90 degree days were recorded at DIA.
In terms of precipitation, Thornton measured 1.55 inches in the rain bucket over the course of the month. This was slightly below Denver’s August average of 1.69 inches.
The airport however fared better with 2.73 inches as many of the afternoon storms didn’t really get started until they were past Thornton.

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.
All-in-all, while temperatures and precipitation rain a bit lower than average, June 2014’s weather was pretty close to what we typically expect to see. Thunderstorms made their appearances as always but we were spared much in the way of severe weather.
A series of fronts and troughs moved through northern Colorado during the month. This helped to keep temperatures down and provided thunderstorms with a bit of regularity.
Thornton’s average temperature for the month came in at 66.5 degrees. This is less than one degree below Denver’s historical June average of 67.4 degrees. The Mile High City’s average came in slightly warmer at 67.3 degrees.
Temperatures in Thornton ranged from a high of 92.1 degrees on June 3rd down to a low of 38.2 degrees on the morning of the 9th. Denver was warmer on both measurements with a maximum reading of 94 degrees on the 26th and a low of 42 degrees on the 15th.
Six days saw temperatures top the 90 degree mark in Thornton and Denver. This is below the historical average of 7.9 days of 90 degree or warmer readings we expect to see.
No temperature records were set during the month.
In terms of precipitation, Thornton had 1.59 inches fall into our rain bucket. Denver was a bit wetter with 1.82 inches. Both fell below the June average of 1.98 inches. Thornton saw eight days with measurable precipitation, Denver nine.
Denver set a daily precipitation record of 0.51 inches on the 27th. This bested the old record for that date of 0.29 inches in 1949. Thornton recorded 0.60 inches on the same day.

The month of May was a relatively benign, uneventful month in terms of the weather in Thornton. Average temperatures were right on par with normal while precipitation was generous.
We started out the month with warming temperatures and by the third we were seeing highs in the 80s. This only lasted a few days before cooler than normal temperatures settled in for a 10 day period.
It was during that period that we recorded precipitation for six straight days. This included a good shot of snow on the 11th and 12th.
Temperatures bounced back on the 18th and 19th with highs above 80 degrees but then settled down again to predominantly cooler than normal conditions for the next week. The period from the 20th to the 25th also saw a return to wet conditions.
Warmer and dry conditions returned for a few days and then we closed out the month with cooler temperatures and some more rain.
Thornton finished the month with an average temperature of 56.9 degrees. This was just a hair lower than Denver’s May average of 57.1 degrees. The Mile High City’s average temperature came in warmer at 57.5 degrees.
The hottest temperature recorded occurred on the 29th with a reading of 88.7 degrees. The coldest temperature of 28.5 degrees was on the 14th. Denver’s warmest reading was 85 degrees on the 4th and its coldest of 30 degrees was on the 12th.
In terms of precipitation, Thornton saw a healthy 4.26 inches of liquid precipitation. This was well above the May average of 2.12 inches. Similarly, Denver saw above normal precipitation with a reading of 3.51 inches.
Snow fell on two days and totaled 4.3 inches in Thornton. Out at DIA, only 1.1 inches was recorded. Average snowfall for May in Denver is 1.1 inches.

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.
Colorado’s famously highly variable weather seems to showcase itself during the month of May when a variety of weather conditions can be seen.
Winter-like temperatures and snow are possible as are mid-summer like temperatures or the more typical spring severe weather.
As the month starts out in 2014 we are going to enjoy a mild period with unseasonably warm temperatures and dry conditions. Long range forecasts predict a relatively ‘normal’ May.
However the month can bring extremes. Snow is not entirely uncommon during the month, oftentimes causing damage to newly bloomed trees. More common however is severe weather, particularly in the latter half of the month. Thunderstorms become more frequent and their associated hazards – lightning, wind, hail and tornadoes – are usual visitors.
The month of April lacked much in the way of drama for northeastern Colorado. Overall temperatures were warmer than normal and precipitation and snow were lacking a bit.
April started out on the cool side and brought the first snow of the month on the 3rd. By the 8th temperatures had rebounded and we enjoyed a five-day stretch of high temps in the 70s.
A storm system and cold front cooled things down on the 13th and we saw a couple of days of light snowfall. As always the weather bounced back and Thornton recorded its first 80+ degree day of the year on the 18th.
The final four days of the month saw things turn cool again. Some light rain was seen but the bigger story was a period of unusually windy conditions.
Denver’s average April temperature is 47.4 degrees (1981 – 2010). For April 2014, the average temperature in Thornton was more than two degrees higher at 49.6 degrees. Out at Denver International Airport, the average came in a bit cooler at 49.0 degrees.
Temperatures in Thornton ranged from a high of 81.3 degrees on the 18th down to a low of 17.6 degrees on the 14th. DIA saw its warmest reading of 80 degrees on the 22nd and its coldest of 18 degrees on the 14th.
Low temperatures dropped below freezing on 11 days in Thornton. No readings below zero were recorded.
In terms of precipitation, Thornton measured 0.97 inch in the bucket. This is a good ways below the Denver April average of 1.71 inches. DIA saw more precipitation than us with a reading of 1.24 inches.
Similarly, snowfall fell short of normal in Thornton and Denver. On average the Mile High City sees 6.8 inches in April. Thornton recorded only 5.5 inches and DIA 5.6 inches.

A scene from a new NASA video shows Colorado’s West Fork Fire in June 2013 among other area weather and climate events. (NASA / YouTube)
A stunning video released by NASA this week provides a bird’s eye view of some of the Earth’s most significant weather and climate events of last year.
Using images and movies from satellites and the International Space Station, scenes from across the globe are shown in the video titled “Earth from Orbit 2013.”
Colorado and surrounding states however will draw the most attention from many locally.
From their perch high above, imagery of Colorado’s West Fork Fire in June 2013 is seen as well as the effects of the September floods.
To our south, the drought in New Mexico is seen having taken its toll on Elephant Butte Reservoir in New Mexico. The veritable explosion of storm cells that lea to devastation in Oklahoma during a May tornado outbreak are also shown.
Below the video you will find a description of each scene and links to more imagery.
From NASA – Published on Apr 21, 2014:
A fleet of orbiting satellites monitors Earth constantly. The satellites from NASA and other space agencies give us a fresh, wide perspective on things that we can see from the ground — and things that we can’t.
A look back at Earth in 2013 from the viewpoint of orbit reveals the kind of data gathering and technical achievement that are the reason NASA puts Earth-observing satellites in space. A visualization of satellite and computer model data shows how a cloud of dust from the Chelyabinsk meteor moved around the world. NASA satellites measured the intensity of wildfires, the salinity of the oceans and rainfall around the globe — whether it was too little or too much.

Looking back at the month of March we see a period of relatively uneventful weather in the Denver area. Temperatures were near normal as was the amount of liquid precipitation, this despite the fact we saw well below normal snowfall.
The month started very cold with the first two days failing to record readings above freezing and some light snowfall. That did not last long however and four mild days followed. A weak system then moved in with a couple more shots of snow over a three day period.
Entering the second week of the month temperatures moderated and we saw some of our warmest readings of the month. Light snow on the 12th fell but did not cool things down too much.
Two more very light snowfalls occurred in the last 10 days of the month while temperatures overall remained at or above normal.
Thornton’s average temperature for the month came in at 41.1 degrees, 0.7 degrees above the Denver average for March of 40.4 degrees. Out at Denver International Airport, the Mile High City saw an average monthly temperature of 40.9 degrees.
Our warmest temperature for the month occurred on the 9th when the mercury climbed to 75.0 degrees. The coldest reading of 3.8 degrees happened on March 2. Denver’s warmest and coldest temperatures were on the same days with readings of 73 degrees and 4 degrees.
Two days, the first and the second, saw high temperatures below freezing. Low temperatures below freezing occurred on 22 of the 31 days. Denver saw similar readings.
In terms of liquid precipitation, Thornton recorded 1.06 inches. This was a bit above Denver’s March average of 0.92 inches. Denver was drier than normal recording 0.83 inches.
The near normal precipitation came despite the fact we saw much less snow than normal. March is typically our snowiest with an average of 10.7 inches of the white stuff. Thornton saw a mere 6.5 inches and Denver 6.0 inches.
