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.

A new Pentagon report says that climate change is an “urgent and growing threat to our national security” and blames it for “increased natural disasters” that will require more American troops designated to combat bad weather. Some studies have questioned whether such a trend exists. Says the Pentagon report released Wednesday, “Global climate change will have… Continue reading Climate change ‘urgent and growing threat’ to national security: Pentagon→

The month of June was a rather eventful one with wetter than normal conditions starting things out and temperatures coming in quite a ways above normal. Further, the month lived up to its reputation as Colorado’s severe weather month with numerous notable thunderstorms and a good bit of tornado activity.
The month started out warm and dry but on the 3rd a cold front moved in cooling things down and bringing healthy shots of rain. On the 4th and 5th Thornton saw more than a half inch of rain on each day.
To our north, the 4th brought extreme weather in the form of an EF-3 tornado near Berthoud and multiple, smaller tornadoes in the Simla area to the southwest.
We then dried out a bit and warmed up but on the 9th another cold front arrived. Like the previous system, cooler temperatures and a decent shot of rain followed.
In the first 18 days of the month, Thornton saw 14 days with measurable precipitation. That however chanced for the latter third of the month as we dried out and warmed up significantly. There were still days with thunderstorms but the bulk of them seemed to just miss Thornton for the most part.
Such was the case of the 24th when extreme weather hit to our south. While we saw just a bit of rain, other areas near central Denver recorded far more and an EF-1 tornado struck from northeast Denver to northwest Aurora.
Overall Thornton’s monthly average temperature for June 2015 came in at 69.0 degrees. This was a good ways above the long term June average for Denver of 67.4 degrees. Out at the airport, the Mile High City’s official average reading was 69.5 degrees.
Temperatures in Thornton ranged from a high of 94.3 degrees on the 21st down to a low of 50.5 degrees on the morning of the 6th. Denver’s highest reading of 94 degrees came on the 30th and its lowest of 51 degrees on the 3rd.
In terms of precipitation, both Thornton and Denver recorded identical amounts in their rain buckets. The 2.53 inches of precip bested Denver’s June average of 1.98 inches by a good bit. In all, Thornton saw 16 days of measurable precipitation while Denver recorded 13.

June 6, 2015 – An amazing June sunset in Thornton. (Michelle Jones)
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.

The first quarter of the year started out dry but April started to signal a turn toward wetter conditions and the month of May certainly followed through on that. Not only was it a very wet month, it was also much cooler than normal.
A seemingly endless series of disturbances moved through the state almost from the first day through the last day of May 2015. We started out dry but the third of the month began the wet period with five straight days of precipitation. That was capped off by a decent shot of snowfall on the 10th of the month.
After that we did dry out for at least a few days before the wet weather returned on the 15th, albeit with lesser amounts of precipitation overall. By the time the month was over, 18 of the 31 days had seen measureable precipitation in Thornton.
Temperatures were quite cool for the month with the average in Thornton coming in at 52.2 degrees. This was nearly five degrees below Denver’s May average of 57.1 degrees. As measured at Denver International Airport, the Mile High City officially saw an overage of 53.0 degrees.
Thornton’s mercury readings ranged from a high of 87.3 degrees on the 31st down to a low of 27.8 degrees on the morning of the 10th. Denver saw its warmest reading of 85 degrees on the 31st also and its coldest reading of 27 degrees occurred on the 9th and 10th.
In terms of precipitation, the numbers help to showcase just how wet of a month it was. Here in Thornton we recorded 6.40 inches of liquid precipitation, far above the long term Denver average for May of 2.12 inches. Officially, Denver also saw above normal precipitation although not by near as much as they recorded 3.76 inches.
That reading was not enough to push May 2015 into the books as one of the top 10 wettest Mays. However, the airport’s outlying location as compared to historical measurement sites is probably the only reason why. As Thornton’s measurement and those of other station’s shows, we were far wetter than what DIA saw.
Snowfall in May is not unusual and Thornton saw 5.1 inches from one storm on the 9th and 10th. Out at the airport 4.0 inches was recorded. Both were a good bit above the May average of 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.
