Following on yesterday’s record-setting performance, the mercury once again rose to levels never before seen on this date.
At 12:53pm the station at Denver International Airport reported 82 degrees. This easily bested the previous record for October 28 of 80 degrees last set in 1994.
Here in Thornton we were actually a bit warmer reaching 83 degrees at 3:34pm.
At this time it is certain that October 2016 will go into the record books as one of the 10 warmest Octobers in Denver history. Where it ends up on the list is yet to be determined but it is likely to be around the fourth or fifth warmest.
For the second time this month, the Mile High City broke a record high temperature. The new mark beats a reading that had stood for 50 years.
At 3:23pm today the mercury at Denver International Airport topped out at 83 degrees. This easily bests the previous record for this date of 80 degrees last hit in 1966.
Here in Thornton we were just a notch cooler with a high of 82 degrees.
This is the second time this month Denver set a record high. The first came on October 15 with a reading of 85 degrees that beat the previous mark of 83 degrees.
We may not be done setting records either. The record high for tomorrow is 80 degrees as well, set in 1994 and years prior. Right now the forecast calls for us to reach that same temperature although cloud cover may prevent that from happening.
What will this winter have in store for Thornton? Forecasters at the Climate Prediction Center have released their outlook and for the Front Range, it doesn’t hold much in the way of clues.
The CPC does show odds favor above average temperatures for much of Colorado for the period from December through February. In terms of precipitation, the agency gives equal chances of near average, well above average, or well below average precipitation for most of the state. The one exception is the southern third of Colorado which they peg at having above average chances of a drier than normal year.

October 20, 2016 – Forecasters at NOAA’s Climate Prediction Center issued the U.S. Winter Outlook today, saying that La Nina is expected to influence winter conditions this year. The Climate Prediction Center issued a La Nina watch this month, predicting the climate phenomenon is likely to develop in late fall or early winter. La Nina favors drier, warmer winters in the southern U.S and wetter, cooler conditions in the northern U.S. If La Nina conditions materialize, forecasters say it should be weak and potentially short-lived.
“This climate outlook provides the most likely outcome for the upcoming winter season, but it also provides the public with a good reminder that winter is just up ahead and it’s a good time to prepare for typical winter hazards, such as extreme cold and snowstorms,” said Mike Halpert, deputy director, NOAA’s Climate Prediction Center. “Regardless of the outlook, there is always some chance for extreme winter weather, so prepare now for what might come later this winter.”
Other factors that often play a role in the winter weather include theArctic Oscillation, which influences the number of arctic air masses that penetrate into the South and create nor’easters on the East Coast, and the Madden-Julian Oscillation, which can affect the number of heavy rain events in the Pacific Northwest.
The 2016 U.S. Winter Outlook (December through February):
Wetter than normal conditions are most likely in the northern Rockies, around the Great Lakes, in Hawaii and in western Alaska
Drier than normal conditions are most likely across the entire southern U.S. and southern Alaska.
Temperature
Warmer than normal conditions are most likely across the southern U.S., extending northward through the central Rockies, in Hawaii, in western and northern Alaska and in northern New England.
Cooler conditions are most likely across the northern tier from Montana to western Michigan.
The rest of the country falls into the “equal chance” category, meaning that there is not a strong enough climate signal in these areas to shift the odds, so they have an equal chance for above-, near-, or below-normal temperatures and/or precipitation.
Drought
Drought will likely persist through the winter in many regions currently experiencing drought, including much of California and the Southwest
Drought is expected to persist and spread in the southeastern U.S. and develop in the southern Plains.
New England will see a mixed bag, with improvement in the western parts and persistence to the east.
Drought improvement is anticipated in northern California, the northern Rockies, the northern Plains and parts of the Ohio Valley.
This seasonal outlook does not project where and when snowstorms may hit or provide total seasonal snowfall accumulations. Snow forecasts are dependent upon the strength and track of winter storms, which are generally not predictable more than a week in advance. However, La Nina winters tend to favor above average snowfall around the Great Lakes and in the northern Rockies and below average snowfall in the mid-Atlantic.
NOAA produces seasonal outlooks to help communities prepare for what’s likely to come in the next few months and minimize weather’s impacts on lives and livelihoods. Empowering people with actionable forecasts and winter weather tips is key to NOAA’s effort to build aWeather-Ready Nation.
Our unseasonably warm and dry weather of recent months has continued right into October and culminated with a record high for the date.
At Denver International Airport, where the Mile High City’s official measurements are taken, the high temperature today topped out at 85 degrees. That bests the previous record high for the date of 83 degrees set in 2014.
Here in Thornton, we came close to Denver’s mark with our high of 83.5 degrees coming at 1:35pm.
Looking ahead, we’ll see similar high temperature readings tomorrow. We will then start to cool down as a system moves through from the Pacific Northwest. Get the forecast here.
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. Given the lack of precipitation of the last few months though, we certainly would welcome some moisture.
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.

The month of September was overall a pleasant one however that came at a price. A very distinct lack of precipitation led to dry conditions, a trend that had started earlier in the summer.
High pressure was the general rule for the month and that helped to ensure that any significant weather potential was steered away from the state. A few troughs and cold fronts mixed things up but in the end, we only saw precipitation on three days during the month and the amounts were negligible.
Thornton’s average temperature for the month came in at 63.7 degrees. This was just slightly above Denver’s long term average for September of 63.4 degrees. Out at the airport where Denver’s official measurements are taken, it was a good bit warmer with an average of 66.0 degrees.
Temperatures here ranged from a high of 91.6 degrees on the 5th of the month down to a low of 39.8 degrees on the 24th. DIA recorded a maximum of 93 degrees, also on the 5th, and a low of 37 degrees on the 10th.
In terms of precipitation, Thornton saw a measly 0.05 inches fall into our rain bucket. The airport fared far better with 0.28 inches. However, both measurements were well below the September average for Denver of 0.96 inches. The reading in Thornton would have been low enough to tie for the third driest reading in Mile High City history.

Wildlife is still quite active along the Front Range and flowers will hold on to their petals for at least the first part of the month. Then of course there is the weather which you never know what to expect. Thunderstorms, heavy rain, and even snow are a possibility.

Our August weather was a bit of a mixed bag by the two biggest standards. On one hand, it was cooler than normal which was nice. On the other, we saw less than half the amount of precipitation we normally see during August.
August typically is when the monsoon kicks in and we see healthy doses of precipitation. This year however, the monsoonal flow was regularly disrupted by troughs digging in from the north and west.
August 2016 top shots: Monthly photo slideshow
We certainly started the month hot with three days of temperatures near or above 95 degrees. Things then cooled down for a few days as the first trough moved through. Warmer temperatures then returned with readings not too far off of normal for the next two weeks. The final 10 days or so of the month then saw cooler conditions with the majority of days recording readings below normal.
Thornton’s overall average temperature for the month came in at 69.5 degrees. That was three degrees cooler than Denver’s long term average of 72.5 degrees. Out at the airport where Denver’s official measurements are taken, the airport split the difference with an average of 71.2 degrees.
Temperature ranged from a high of 97.2 degrees on the third of the month down to a cool 46.7 degrees on the 25th. Denver saw a maximum of 97 degrees on the 9th and a low of 47 degrees on the 25th. Thornton saw 14 days with highs at or above 90 degrees while Denver recorded 15.
Officially, one temperature record was made. On the morning of the 27th the mercury at DIA dropped to 48 degrees typing the record low for the date.
In terms of precipitation, Denver averages 1.69 inches during the month of August. Thornton saw only 0.76 inches in our rain bucket. The airport fared even worse with only 0.22 inches making the month the eight driest August on record in Denver.

Following on what was a cool but dry August, some are certainly hoping for a bit of precipitation. The month can bring plenty of rain and even 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.

As the calendar turns to August, the summertime heat begins to fade and that makes it easier to get out and enjoy all of the outdoor activities Colorado has to offer. From a walk in a park to afternoon thunderstorms to an abundance of wildlife, photo opportunities abound as is seen in our slideshow.
Our monsoon season typically arrives about now and that means better chances for moisture. However with limited instability, the intensity of storms are more sedate. That doesn’t mean however that the weather is any less photographic.
Slideshow updated August 31, 2016
By the end of the month some of our seasonal feathered friends will be looking to leave the state giving our last chance to see them till spring. Larger mammals are gearing up for the rut (mating season) and that can make for some intense scenes.
