This Week In Denver Weather History

August 2 to August 8: This week in Denver weather history

On first glance our look at this week in Denver weather history appears to be less eventful than many we have looked at previously. However, the severity of the events that appear on the historical weather calendar this week are enough to make you stand up and pay attention. While August is typically a pretty quiet weather month, it is clear that severe weather can certainly strike and Thornton is mentioned in more than one significant event.

From the National Weather Service:

2

In 1878…the high temperature reached 100 degrees in downtown Denver.

In 1911…an apparent dry microburst produced sustained west winds to 42 mph.

In 1973…hail to 3/4 inch diameter was reported in Boulder.

In 1986…a major outbreak of severe thunderstorms occurred along the Front Range. Thunderstorms developed explosively. Some places were hit by large hail twice. Two inch diameter hail broke car windows on I-25 west of Brighton…and up to 1 1/4 inch hail broke windows in Thornton. Baseball size hail damaged several planes near Watkins. Funnel clouds were sighted around Aurora. Hail over 1/2 inch in diameter covered the ground 3 to 4 inches deep at Hudson northeast of Denver. Most of the hail fell north of metro Denver…but 3/4 inch diameter hail was measured at Stapleton International Airport. Total damage from the hail storms this day was estimated at over 10 million dollars.

In 1991…late afternoon thunderstorms produced heavy rain across metro Denver. Two feet of water covered parts of I-25 in southeast Denver…while one foot of water covered parts of U.S. Highway 285 in Englewood. Thunderstorm rainfall totaled 0.50 inch at Stapleton International Airport.

In 2001…severe thunderstorms producing heavy rain and hail… Either washed out or damaged several County roads in the Watkins and Bennett areas.

July 2015 weather recap: Cooler than normal temps, a bit drier than average

Sunday, August 2nd, 2015 4:32am MDT

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.

Thornton’s weekend to offer seasonal temps, pleasant conditions

Friday, July 31st, 2015 5:47am MDT

We close out July and begin the month of August with pretty typical weather for this time of year.  Temperatures are going to be right near average and there will be a few chances for thunderstorms.

For Friday, we start out with sunny skies followed by a few clouds arriving by late morning.  The afternoon may bring some isolated thunderstorm activity.  Look for afternoon highs to reach around 89 degrees.

Saturday will see a few clouds but overall mostly sunny skies will rule.  Temperatures will be similar to today and we are not expecting any storm activity.

The weekend closes out on Sunday with weather conditions much like today.  Temperatures will be a couple of degrees warmer.  Mostly sunny skies start things off and the afternoon brings a slight chance for thunderstorms.

Have a great weekend and of course monitor http://www.thorntonweather.com/ for all the latest.

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.

  • Slideshow updated July 31, 2015

Recreationalists head outdoors and take advantage of urban, suburban and rural opportunities.  As they do, our abundant wildlife that is found just about anywhere comes into focus.

A pleasant, seasonal Thursday for Thornton

Thursday, July 30th, 2015 5:03am MDT

Not much change in our weather for today from what we have seen recently.  Temperatures will be a few degrees warmer than yesterday and conditions will be quite nice overall.

We start out the day under mostly sunny skies.  Some increase in clouds will be seen after noon but plenty of sun should remain.

Temperatures will be climbing to right near the average for the date of 90 degrees.

Thunderstorm activity should remain south and east of us.  However we can’t entirely rule out some isolated activity in the evening.

Keep an eye on current conditions with our real-time weather gauges here.

This Week In Denver Weather History

July 26 to August 1: This week in Denver weather history

Weather can be deadly – we are all well (hopefully) aware of that.  Looking at this week in Denver weather history we are reminded of that and the tragedy that weather can bring to our state.  We see numerous cases of lightning causing death and injury but no one incident highlights the dangers of weather more than what occurred on July 31, 1976.  The Big Thompson Flood was Colorado’s worth weather-related disaster and claimed 144 lives.  More details on all these events are below.

13-5

In 2008…a streak of 26 consecutive days of 90 degrees shattered the previous record of 18 consecutive days established in 1901 and 1874.   Ironically…no new single day record high temperatures were set in the month of July. In August however…a record of 104 degrees was set on the 1st…and another record of 103 degrees was set on the 2nd. In addition…a record low min of 70 degrees was set on August 2nd.

18-2

In 1987…a streak of 16 consecutive days of 90 degrees ranked 4th on the list of hot streaks.  The record of 24 consecutive days was established in the summer of 2008.

26

In 1891…a thunderstorm produced sustained northeast winds to 44 mph with gusts to 60 mph and 0.16 inch of rain.

In 1894…a thunderstorm produced sustained southwest winds to 36 mph with gusts to 58 mph…but only 0.04 inch of rain.

In 1910…the high temperature reached 100 degrees in downtown Denver.

In 1959…a Denver man was stunned while standing by a car that was struck by lightning.  He was treated for burns and shock at a local hospital.  Thunderstorm winds gusted to 55 mph at Stapleton Airport.

In 1983…two heavy thunderstorms hit the northern and western suburbs.  The first drenched Northglenn with an inch of rain in 30 minutes.  The second storm dumped an inch or more of rain in Idaho Springs and Evergreen.  The heaviest rainfall… 2.90 inches in an hour…caused minor street flooding in Golden.

In 1984…heavy early morning thunderstorms drenched the foothills southwest of Denver.  Rainfall to 1 1/2 inches in just 30 minutes occurred between Evergreen and Conifer.  In nearby turkey creek canyon…1.80 inches of rain was recorded in 35 minutes.

In 1985…a long rope-like white tornado touched down 5 miles east of Erie and stayed on the ground…mainly over an open field…for 18 minutes.  However…the twister damaged a few cars on I-25 and injured 3 people from broken glass.  The storm flipped over a van…blew out car windows…and ripped a highway sign.  It also blew an outbuilding off its foundation.  A tornado also touched down briefly 8 miles north of Bennett.  No damage was reported from this storm.

In 1988…a 9-year-old girl was slightly injured by lightning in Parker.

Slightly cooler than normal temps, calm conditions for Wednesday

Wednesday, July 29th, 2015 5:27am MDT

Thornton is set to enjoy a rather pleasant summer day today similar to yesterday.  We continue to be under the influence of a ridge which will give us pretty stable conditions.

We start out with mostly sunny skies and those will last through the day.  Just a few more clouds will form as the day progresses.

Temperatures will be warming to a high in the mid-80s, a bit below the average for the date of 90 degrees.

There is just the slightest chance for some thunderstorms along the Front Range this evening.  However, if any form they are expected to be few and far between and not offer much more than gusty winds.

Stuck in the office? Use our webcams to keep an eye on the sky outside.
