For the second day in a row, the Mile High City has set or tied a record low temperature. The events certainly bring to mind the quickly approaching fall.
This morning, as measured at Denver International Airport, Denver’s temperature officially dropped to a low temperature of 47 degrees. This bests the previous record low temperature for August 19 of 48 degrees last set in 2002.
Here in Thornton we actually were a bit cooler as we dipped to 45 degrees, our coldest reading since May 30. This was also the coldest temperature on August 19 we have recorded in Thornton since ThorntonWeather.com came online in 2006.
From record heat to record cold. As measured at Denver International Airport, the temperature in the Mile High City dropped to 47 degrees at 5:17am. This tied the record low temperature for the date last set in 1960.
The month of July continued the recent trend of cool, damp weather. By the time it was said and done though, while temperatures overall were below average, precipitation fell short of normal.
Temperatures were at or above normal for the first few days allowing for a pleasant Independence Day.
The day after, however, a monsoonal weather pattern cooled things down and brought most of the month’s moisture over the following 10 days.
Ridging then built and we settled into a relatively normal period for the final two weeks although precipitation became scarcer.
Thornton saw an average temperature for July 2015 of 71.2 degrees. This was a good bit below the long term Denver average of 74.2 degrees. Out at Denver International Airport where the Mile High City’s official measurements are taken, the average for the month was 72.8 degrees.
Our temperatures ranged from a high of 96.1 degrees on the 27th down to a low of 53 degrees on the 11th. Denver saw a maximum of 97 degrees and a minimum of 52 degrees.
Denver averages 2.16 inches of precipitation during July. Thornton fell a bit short of that mark recording 1.76 inches. At the airport, only 1.06 inches was recorded.

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.
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.

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.
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 2015 we are going to enjoy a mild period with unseasonably warm temperatures but with unsettled conditions. Long range forecasts lean toward overall warmer than normal temperatures and above normal precipitation.
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.
We began the month of April in the need of moisture and while we didn’t do much to bolster our snowfall numbers, rain proved to be a big help. Temperatures were relatively stable but did end up a bit above average.
The first half of the month offered mostly dry conditions and warmer than normal temperatures. The only real exception was a light snowfall on the 2nd and 3rd of the month. Otherwise we saw virtually no precipitation for the first 15 days of April.
The latter half however saw a shift in the weather pattern courtesy of a number of storm systems that moved through. These led to cooler temperatures and some nice shots of precipitation.
A system on the 15th and 16th brought only 3.9 inches of snowfall but a healthy 1.68 inches of liquid precipitation from snowmelt and rain. We then remained mostly dry up until the 26th when another good shot of rain arrived.
Thornton’s average temperature for April 2015 was 49.0 degrees, a good bit above the long term April average of 47.4 degrees. Out at the airport, Denver saw similar readings to ours with an average of 48.7 degrees.
Temperatures in Thornton ranged from a low of 24.0 degrees on the morning of the 4th up to a high of 80.7 degrees on the 30th. Denver’s coldest reading was 27 degrees on the 3rd and its warmest came on the 30th with a temperature of 79 degrees.
In terms of precipitation, Thornton saw 2.68 inches of precipitation for the month. Officially, as measured at DIA, Denver took a very similar 2.65 inches into their bucket. Both readings were a good ways above the April average of 1.71 inches.
Snowfall failed to be anything extraordinary. Both Thornton and Denver saw 5.3 inches of the white stuff, a good bit below the average of 6.8 inches.

The month of March was relatively uneventful and lacked any sort of real weather drama. What was notable was the dry conditions and unseasonably warm temperatures that dominated for the most part.
March started out considerably colder than normal with the first five days of the month seeing temperatures around 20 degrees below normal. A light shot of snow was recorded on the fourth of the month, a reading that would be our biggest snowfall for the period.
Temperatures began to turn warmer on the sixth with above normal readings recorded through the 16th of the month. We even managed two 80+ degree days on the 15th and 16th.
Denver actually saw its earliest 80 degree reading in history on the 16th. The previous earliest 80 degree reading occurred on March 18, 1907.
Unsettled conditions interrupted the warmth on the 25th with a light snowfall and colder temperatures.
We then bounced right back to the dry, mild conditions for the balance of the month.
Thornton’s average temperature for the month came in at 44.9 degrees. This was well above the long term Denver average of 40.4 degrees. Out at DIA, the Mile High City’s reading was very similar at 45.0 degrees.
Temperatures in Thornton ranged from a high of 82.6 degrees on the 16th down to a low of 9.2 degrees on the 5th of the month. At the airport, Denver’s maximum for the month of 81 degrees came on the 16th with its lowest of 2 degrees on the 5th.
Denver officially broke two temperature records in March 2015. On March 6th the high temperature of 79 degrees broke the record high for the date (previously 76 degrees set in 2013). Also, on the 16th, the high temperature reading of 81 degrees was a record (previously 75 degrees in 2012).
In terms of precipitation, the rain bucket totals fell well short of the March average of 0.92 inch. Here in Thornton a mere 0.49 inches was recorded while Denver saw quite a bit more with a measurement of 0.79 inches.
March is historically our snowiest month but that was certainly not the case in 2015. Thornton snowfall totally only 2.8 inches and Denver was at 2.9 inches. Both were well below the average of 10.7 inches.
