This Week In Denver Weather History

August 7 to August 13: This week in Denver weather history

As we get further into the month of August severe weather is less common. It can however still strike as we see in our look at this week in Denver weather history. Everything from torrential rains to massive hail and even a tornado have been reported.

From the National Weather Service:


In 1948…a brief west moving tornado was sighted 3 miles north-northeast of Stapleton Airport. The white funnel silhouetted against a gray cloud background was very narrow…nearly vertical…and estimated at nearly 5 thousand feet high. A dust cloud formed on the ground around the funnel. No damage was reported.

In 1952…a thunderstorm wind gust to 52 mph was recorded at Stapleton Airport.

In 2014…severe thunderstorms produced large hail across western and southern parts of metro Denver. Near Centennial and Golden…hail up to quarter size was reported. Near Bennett…a peak thunderstorm wind gust to 65 mph was also reported. At Denver International Airport…a peak wind gust to 46 mph was recorded.


In 1874…swarms of grasshoppers invaded the city. Millions of them were seen cruising through the air. The insects were apparently picked up by a thunderstorm gust front and carried into the city. The grasshoppers had ravaged crops in surrounding counties for the last month.

In 1878…the highest temperature ever recorded in Denver…105 degrees…occurred at 3:20 pm. This temperature was equaled on July 20th in 2005.

In 1969…the temperature reached 100 degrees at Stapleton International Airport.

In 1976…in Thornton…a 13 year old boy riding a bicycle was struck and killed by lightning.

In 2000…lightning struck three homes in central Arapahoe County east of Denver. Damage was estimated at 47 thousand dollars.

In 2003…hail to 1 inch in diameter pelted Denver. Hail to 7/8 inch was measured in Boulder.

In 2008…heavy rain also caused flash flooding over south Denver and its nearby suburbs. Heavy rain…from 2.5 to 4 inches…fell in less than 90 minutes. Firefighters rescued 20 people as the water quickly rose along creeks…flooded roadways…and stranded motorists. Three people had to be rescued along Cherry Creek when the bike path flooded.

In Evergreen…a man suffered minor injuries when he was struck by lightning. It entered his finger…traveled down his body… And exited his foot.

In 2013…heavy rain caused localized flash flooding in Aurora. An undergound parking garage at an apartment complex was inundated with 3 to 4 feet of water. Flash flooding forced a road closure at East Mississippi Ave. and Alton St. Also… several people had to be rescued when three vehicles stalled in floodwaters at Alameda Ave. and Havana St. The stationary thunderstorms dumped 2.75 inches of rain in less than 45 minutes. In addition…large hail…up to one inch in diameter… was reported north of Roxbourough State Park. At Denver International Airport…just a trace of rainfall was observed.


In 1979…heavy thunderstorm rains on each of three consecutive days dumped a total of 2.22 inches of rain at Stapleton International Airport. The heaviest rain… 0.95 inches…fell on the 9th. Small hail to 1/8 inch diameter fell on the 8th.


In 1875…clouds of grasshoppers were seen flying through the air on the prevailing winds during each day.


In 1900…a thunderstorm produced west winds sustained to 47 mph with gusts to 55 mph…but only 0.01 inch of rain.

In 1902…a thunderstorm produced no rain and north winds sustained to 52 mph with gusts to 60 mph.

In 1934…heavy cloudbursts in the foothills near Kittredge and at the head of Mount Vernon creek caused flash flooding on both Bear Creek and Mount Vernon Creek at Morrison… Which resulted in 6 deaths and much property damage. The highway in Mount Vernon canyon was destroyed by the flood waters.

In 1981…3/4 inch hail fell at Kittredge near Evergreen in Jefferson County.

In 1987…3/4 inch hail fell in Boulder and 9 miles northwest of Castle Rock.

In 1995…lightning struck a 16-year-old counselor in the back of the head while he and a friend were standing under a tree at the singing river ranch…7 miles west of Evergreen. He stopped breathing…but his friend was able to summon help and they were able to revive him. He was hospitalized for a few days and released.

In 1998…brief…weak tornadoes (f0) were sighted near Bennett and Roggen. No damage was reported. Hail as large as 1 inch diameter fell in Franktown with 3/4 inch diameter hail measured near Castle Rock. Thunderstorm winds gusted to 61 mph near Roggen.


In 2006…mid and high cloudiness overnight on both days resulted in two temperature records. The low temperature of 71 degrees on the 9th was a record high minimum for the date. The low temperature of 68 degrees on the 10th equaled the record high minimum for the date first set in 1936.


In 1924…0.01 inch of rain fell over downtown Denver. This along with the 0.01 inch of rainfall on the 4th was the only rainfall of the month…making this the driest August on record in the city.

In 1962…the high temperature reached 100 degrees at Stapleton Airport.

In 1970…hail stones to 1 inch in diameter were reported in the Fort Lupton area.

In 1972…dry thunderstorm microburst winds gusting to 46 mph briefly reduced the surface visibility to 3/4 mile in blowing dust at Stapleton International Airport.

In 1978…lightning struck two men in Aurora…killing one and injuring the other.

In 1982…a tornado was sighted near Castle Rock and remained on the ground for 10 minutes. Wind gusts to 60 mph were reported in Castle Rock. No damage was reported.

In 1994…heavy thunderstorm rains caused flash flooding on Lena Gulch in west metro Denver. Damage was estimated at 50 thousand dollars. Lightning struck a house in Westminster…causing a small attic fire.

In 1996…strong thunderstorm winds toppled a tent at a company picnic in Westminster. Five people received minor injuries when the tent collapsed. Two cars nearby were also damaged by flying debris. A weak tornado (F0)…first sighted near Denver International Airport…traveled east to near Bennett and Strasburg. No significant damage was reported.

In 1998…heavy rain caused flooding and flash flooding problems over southwest metro Denver. An observer in Lakewood measured 3.26 inches of rainfall in an hour. Several streets were flooded in central Lakewood.

In addition…a trailer park along Lena Gulch in Wheat Ridge was evacuated due to high waters. One inch diameter hail fell near Roggen.

In 1999…thunderstorm-producing tornadoes…damaging straight line winds…heavy rain…and hail hammered metro Denver. In the city…small hail and heavy rainfall…up to 2.50 inches an hour…caused a 20-foot by 50-foot section of the roof to collapse at a furniture warehouse. Damage to the warehouse was estimated at 1 million dollars. Heavy rain also flooded several underpasses with up to 3 feet of water…which resulted in a number of stalled vehicles. In Fort Lupton…a tornado bounced across the area. Spotty damage was reported along a 5-mile path as trees…power poles…and lines were downed. In addition…an empty semi-trailer was overturned onto another vehicle northeast of the town. Thunderstorm winds gusted to 81 mph south of Fort Lupton.

Cooler temps, chances for showers for Thornton’s weekend

Friday, August 5th, 2016 5:27am MDT

The three-day period starts out much cooler than what we have seen lately, in fact offering our coolest temperatures in more than two months. We will then warm up each day for the balance of the weekend but remain cooler than normal.

For Friday we have yet to see much in the way of shower activity other than a few sprinkles. Off and on shower activity can be expected throughout the day and into tonight. Skies will be cloudy and temperatures will be topping out in the low 70s, readings we haven’t seen since the end of May.

The low pressure system will gradually shift east Saturday leading to a return of some sun and warmer temperatures. Partly sunny skies will be above with highs in the low 80s. Showers and thunderstorms will be a possibility for the afternoon.

The weekend closes out Sunday with a seasonal kind of day. Temperatures will be reaching the mid to upper 80s with a good dose of sun above. The afternoon brings a typical chance for thunderstorms.

Have a great weekend!

Cold front to bring much cooler weather to Thornton Thursday

Thursday, August 4th, 2016 5:30am MDT

A break from the heat is finally here. A cold front, now pushing through, will offer up temperatures nearly 20 degrees cooler than recent days.

We start out the day with partly sunny skies and that is what will be above throughout the day. This morning we will see some breezy winds as the front works its way through.

Of course the biggest effect of the front is going to be cooler temperatures. Look for today’s high to top out at ‘only’ around the 80 degree mark, much cooler than the mid-90s we have become accustomed to lately.

There isn’t a great deal of moisture with the system but we do see a slight chance for thunderstorms after about 6:00pm. Chances increase after midnight tonight and we do actually have a decent chance to see rain from then into Friday morning.

Enjoy the change!

July 2016 weather recap: Thornton sees near normal temps, below average precipitation

Wednesday, August 3rd, 2016 10:54am MDT

While the month of July seemed hot and dry, statistics show that only one of those two conditions held true.  We definitely saw a big time lack of precipitation but temperatures averaged out to near normal.

High pressure was the dominate feature for the month leading to overall dry conditions.  We started out cooler than normal and somewhat wet for the first two days of the month. That however changed quickly.

From the 3rd through the 17th of the month, Thornton saw temperatures largely remain above normal.  Only two days during that period saw precipitation and both were minimal amounts.  We saw our hottest temperature of the year to date and our only 100-degree temperature reading of the year on the 10th when the mercury topped out at 100.4 Degrees.

On the 14th and 15th of the month, we had a brief respite from the heat as temperatures were a bit below normal.  However, we then put together a string of 12 straight days of 90 degree or hotter readings.

The 28th and 29th then broke the streak with temperatures in the mid to upper 80s.  The month then closed with two days of above normal readings.

Thornton’s overall average temperature for the month came in at 74.7 degrees.  This is just above the long term Denver average for July of 74.2 degrees.  Out at DIA where the Mile High City’s official measurements are taken, the average for this July was much higher at 76.2 degrees.

Temperatures in Thornton ranged from the aforementioned 100.4 degrees on the 10th down to a low of 54.6 degrees on the morning of the 9th.  Denver’s official high for the month was 102 degrees on the 10th and its low of 51 degrees came on the 12th.

In terms of precipitation, Denver averages 2.16 inches during the July.  Thornton fell far short of that with a paltry 0.55 inches of rain in our bucket.  The airport, while receiving nearly double our total at 1.09 inches, was well short of average as well.

This Week In Denver Weather History

July 31 to August 6: This Week in Denver Weather History

How does 42 degrees sound right about now? That mark is one of the highlights of this week in Denver weather history. It was the low temperature recorded twice in our past and the coldest July temperature on record. Many more notable events have also occurred.

From the National Weather Service:


In 2008…a streak of 24 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.


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.


In 1956…96 percent of the total precipitation for the month of July occurred over the last five days of the month. Heavy thunderstorms produced 4.00 inches of rainfall at Stapleton Airport. This amount of precipitation in 5 days or less had been exceeded only 3 times in previous record. The last time had been in December of 1913 as snow. Considerable property damage occurred across metro Denver from flooding.


In 1873…the all-time lowest recorded temperature in July… 42 degrees…occurred. The same temperature also occurred on July 4…1903.

In 1874…during the late afternoon rain and hail fell for 5 minutes followed by brief heavy rain. Pieces of solid ice of irregular shape fell upon the roof of the station. The hail stones measured 1 1/2 inches in diameter. Precipitation (rain and melted hail) was only 0.16 inch.

In 1889…the high temperature climbed to 100 degrees in downtown Denver.

In 1919…heavy thunderstorm rainfall totaled 2.59 inches in downtown Denver during the evening. Rainfall was 1.90 inches in an hour…a new record at that time.

In 1961…over an inch of rain in a short period of time caused flooding of streets and basements in Denver. Rainfall totaled 1.30 inches at 11th and Lincoln in central Denver.

In 1964…the temperature reached 91 degrees in Denver…making this the 27th day of the month that the temperature reached 90 degrees or more. This is the all time record for 90 degree days in a month in Denver.

In 1972…one inch diameter hail fell in Hudson northeast of Denver.

In 1976…during the evening hours extremely heavy thunderstorm rains produced flash flooding in Big Thompson Canyon which killed 144 people between Estes Park and Loveland. No significant weather occurred in metro Denver at the time.

In 1987…1 inch diameter hail fell in Lakewood and 3/4 inch hail fell near Louisville. Southeast Boulder County was drenched with 1.25 inches of rain in just 20 minutes.

In 1993…thunderstorm winds damaged a chimney of a home near Parker.

In 1996…a weak tornado (f0) was sighted 12 miles east of Denver International Airport. No damage was reported.

In 1998…heavy monsoonal thunderstorm rain triggered a mud slide in Blackhawk. The mudslide blocked Main St. and caused an estimated half million dollars in damage to a casino. Heavy thunderstorm rain…up to 3 inches in an hour…caused a flash flood along Buffalo Creek. Portions of County Road 126 just south of the town of Buffalo Creek were washed out. The flood waters nearly washed away the bridge as mud and debris slammed into the structure. Hail to 1 3/4 inches in diameter fell near Idaho Springs.

In 2004…severe thunderstorm winds toppled a 65-foot blue spruce tree in Parker. The tree landed on a home damaging the roof and gutters. The downed tree poked dozens of holes into the shingles.

In 2013…severe thunderstorm winds… with gusts estimated to 80 mph…downed power poles which caused scattered outages in and around Byers…Bennett and Strasburg. Some property damage was also observed. Near Byers…aluminum siding and roofing was peeled off sheds. Large hail…up to one inch in diameter… was reported north of Bennett. At Denver International Airport…a peak wind gust to 40 mph was observed from the northeast.


In 1888…heavy rain in the mountains and foothills caused flooding on clear creek in Golden. The high waters also washed away portions of the railroad tracks in the canyon between Idaho Springs and Golden.

In 1901…the temperature reached a high of 100 degrees in the city.

In 1902…the high temperature climbed to 100 degrees in downtown Denver.

In 1914…a thunderstorm produced 1.00 inch of rainfall in just 21 minutes and north winds sustained at 43 mph with gusts to 50 mph. Rainfall totaled 1.17 inches.

In 1938…the temperature climbed to a high of 100 degrees in downtown Denver…which is the record maximum for the date. The temperature was also recorded on this date in previous years.

In 1976…flight operations at Stapleton International Airport were suspended for 90 minutes when the airport tower radar was knocked out and water reached a foot deep on some taxi ramps after 1.50 inches of rain fell in one hour. Heavy rain also caused minor flooding in east Denver and Aurora where lightning damaged the roof of a home and injured the owner. One young man was swept down a flooded ditch…but was rescued by firemen. A number of rafts were floated in flooded streets. Thunderstorm rainfall totaled 1.71 inches at Stapleton International Airport.

In 1978…a tornado damaged a house and broke a power pole 5 miles northwest of Parker. A microburst wind gust to 52 mph briefly reduced visibility to 1 mile in blowing dust at Stapleton International Airport.

In 1985…heavy thunderstorms roared through the southern and western sections of metro Denver…producing large hail and heavy rain. Lightning hit a recreational vehicle trailer causing it to burn. There was a lot of street flooding over western suburbs where rainfall totaled over 2 inches in some areas. One inch diameter hail was reported in Littleton and near Evergreen. Hail piled 4 to 6 inches deep at Tinytown in the foothills southwest of Denver.

In 1990…a small rope-like tornado was spotted in open country 15 miles southeast of centennial airport. No damage was reported from the twister.

In 1992…pilots reported a funnel cloud near the construction site of the new Denver International Airport. A few minutes later…a tornado was reported near Bennett. The tornado remained on the ground for about 18 minutes and was visible from the national weather service office at Stapleton International Airport. Thunderstorm wind gusts to 70 mph were reported near Bennett and Watkins with a wind gust to 60 mph at Brighton. Two men were injured when struck by lightning. A young man sustained serious injuries when struck by lightning while jet skiing on Cheery Creek Reservoir. A man received only minor injuries when struck by lightning while golfing in Westminster.

In 1994…heavy thunderstorm rains in the foothills west of Denver caused the closure of the Virginia Canyon Road north of Idaho Springs by rocks and debris.

In 2001…a 34 year old man on the South Platte River bike path in Denver received minor injuries when lightning struck a nearby tree. Lightning…coupled with strong thunderstorm winds…knocked out electrical power to about 10 thousand homes and businesses in Golden.

In 2006…strong thunderstorms hit southern metro Denver. A severe thunderstorm wind gust estimated to 71 mph knocked down a tree in Aurora near Cherry Creek. Lightning sparked a fire in a home near lone tree and struck a transformer at an RTD light rail station at Interstate 25 and Yosemite Street. Heavy thunderstorm rainfall forced the closure of Arapahoe Road between Holly and Quebec streets due to high water. Flooding was also reported near Park Meadows Mall and Greenwood Village. Heavy rainfall also caused flooding in Highlands Ranch…lone tree…and Parker. Water up to 6 inches deep was reportedly running over the roads.


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 1972…one workman was killed and another injured when a strong gust of wind destroyed a partially completed apartment building in south Denver. Hail to 1 3/4 inch diameter fell in Golden.

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.

Wednesday offers hot temps, chance for storms late

Wednesday, August 3rd, 2016 5:22am MDT

One more hot day then we expect to see some relief. Today will bring some of the hottest temperatures of the week with some storm activity expected but later than normal.

We start out with mostly sunny skies to be followed by a slow increase in cloud cover as the day progresses. Temperatures will be climbing toward a high in the mid-90s, well above the average for the date of 89 degrees. Some scattered thunderstorms may be seen this evening.

Looking ahead, we continue to track a cold front expected to arrive tomorrow and bring a change in the overall pattern. Temperatures Thursday and Friday should drop into the upper 70s and then warm back up close to normal for the weekend.

Above normal temperatures, slight chance for storms Tuesday

Tuesday, August 2nd, 2016 5:14am MDT

The same weather pattern we have been seeing lately continues today and tomorrow. However, we do continue to expect a change toward cooler conditions for the latter part of the workweek.

For today we start out with mostly sunny skies that will last for the morning and the early afternoon. There will be a little bit of moisture to work with so from mid to late afternoon into this evening we see just a slight chance for thunderstorms. Temperatures today will be climbing into the low to mid-90s.

Looking ahead, tomorrow offers conditions similar to today, perhaps even a bit warmer. After that, we expect a cold front to arrive bringing much cooler mercury readings Thursday and Friday along with better chances for precipitation. More details in the extended forecast.

Thornton’s workweek starts off mild and dry

Monday, August 1st, 2016 6:11am MDT

With drier air now in place, we see our small chances of storms disappear on Monday – not that they have been bringing any precipitation to us anyway.

Sunny skies start things off then we will see a few clouds as the day progresses but overall a healthy dose of sun will be with us. Temperatures will be climb to a high in the low 90s and we aren’t expecting any storm activity.

Looking ahead, Tuesday and Wednesday are expected to continue the heat with minimal chances for storms. However, a trough looks to dig in later in the week and that should provide not only cooler temperatures but better chances for precipitation.
