Calm, cool conditions for Thornton’s Friday and weekend

Friday, February 5th, 2016 5:15am MST

We are on track to enjoy a relatively seasonal three-day period. Temperatures will fluctuate a bit though as the effects of yesterday’s front linger and another weak disturbance moves through late Saturday.

For Friday we start out with a good bit of cloud cover but that will ease through the morning leading to mostly sunny skies by this afternoon. Conditions will be calm, winds light. Temperatures will remain chilly as the trough that moved through works its way east. Look for highs today in the mid to upper 30s.

Saturday looks to be the warmest day of the three-day period. Mostly sunny skies will be above as we head for a high in the mid to upper 40s.

A weak front moves in and that will impact things just a bit on Super Bowl Sunday. We’ll still have plenty of sun though but temperatures will cool to the low to mid-40s.

All in all a pretty nice weekend as we gear up for a Denver Broncos victory!

Thornton’s February weather preview: Month usually brings warmer temps, drier conditions

Thursday, February 4th, 2016 3:48pm MST

Thornton and Denver, Colorado February Weather Preview.February in Colorado typically brings to an end an extended period when average temperatures are at their lowest. Winter begins to loosen its grip and temperatures get warmer but precipitation is not a particularly common event during the month.

Probably one of the biggest question marks is whether or not we will see some help with the snow situation.  While mountain snowpack is not in too bad of shape, Denver’s seasonal snowfall to date is well below normal. February is only our sixth snowiest month so it may not provide much help on the precipitation month.

Temperatures however do usually see a nice rebound during the month. Average high temperatures climb from an average of 44 degrees at the start to 50 degrees by the end of February.

January 31 to February 6: This week in Denver weather history

This Week In Denver Weather History

January 31 to February 6: This week in Denver weather history

Winds can be a blessing and a curse this time of year.  Chinook winds can help warm what is otherwise a normally chilly season.  They can also cause a great deal of damage as they pick up speed as they come roaring across the Front Range.  While we have been lucky thus far this year and not had damaging wind events, looking back at this week in Denver weather history one can’t help but think that maybe it is just a matter of time before they strike.


In 1888…a protracted warm spell lasted a week.  Maximum temperatures ranged from 62 degrees on the 29th to an all time record high for the month of 76 degrees on the 27th.  Daily record high temperatures of 76…69…and 71 occurred on the 27th…28th…and 30th respectively. Record high minimum temperatures of 47 and 34 occurred on the 26th and 27th.


In 1951…a major storm dumped 10.1 inches of snowfall at Stapleton Airport.  Most of the snow…8.3 inches…fell on the 29th.  Cold arctic air accompanied the snow.  Several temperature records were set…including record low maximum temperatures of 4 on the 28th and 4 below zero on the 29th and record low temperatures of 12 below zero on the 29th and 24 below zero on the 31st.  Temperatures were below zero for 45 consecutive hours.


In 1883…a major winter storm dumped 19.3 inches of snow on downtown Denver.  Most of the snow…12.2 inches…fell on the 31st.  This was the heaviest snowfall to hit the city in years.  Temperatures plunged from a high of 52 degrees on the 29th to a low of 13 degrees on the 31st. Precipitation from the storm totaled 2.23 inches.  The 1.22 inches of precipitation on the 31st was the greatest calendar day and 24 hour precipitation ever recorded in the city during the month of January.


In 1908…an apparent strong cold front plunged temperatures 45 degrees in 24 hours from 47 degrees at noon on the 30th to only 2 degrees at noon on the 31st.  North winds were sustained to 30 mph on the 30th.  Snowfall was only 0.8 inch on the 31st.

In 1965…a major storm dumped 10.4 inches of snow over metro Denver.  After 5 inches of snow fell in Boulder… Strong Chinook winds developed…warming the temperature 25 degrees in 90 minutes.  Wind gusts to 97 mph were recorded on Table Mountain in Boulder.  Winds gusts to 53 mph were measured in downtown Boulder where some damage occurred.  Minor wind damage also occurred in western suburbs of Denver.  West winds gusted to 51 mph at Stapleton International Airport on the 31st.

In 2005…a winter storm brought heavy snow to the Front Range foothills.  Storm totals included:  17 inches at Aspen Springs…13 inches 7 miles southwest of Boulder and at Lake Eldora…12.5 inches near Blackhawk…11.5 inches at Rollinsville and near Nederland…11 inches near Evergreen and Golden and at Gross Reservoir…and 10 inches at Cabin Creek.  Lesser amounts of snow fell over the city.  Only 1.9 inches of snow were measured overnight at Denver Stapleton.  North winds gusted to 30 mph at Denver International Airport…where freezing fog during the early morning of the 30th reduced the surface visibility to as low as 1/8 mile.  Light rainfall… Rare in January…totaled 0.06 inch at Denver Stapleton on the early morning of the 30th.


In 1985…a cold front on the 29th produced a protracted cold spell as arctic air remained entrenched across metro Denver. While the only daily temperature record set was a low maximum reading of 2 degrees on February 3rd…minimum temperatures plunged well below zero on 9 consecutive days. The coldest readings were 15 degrees below zero on January 31st and 14 degrees below zero on February 5th.


In 1876…hurricane force winds caused some damage in Boulder.

In 1951…the low temperature plunged to 24 degrees below zero.

In 1933…snowfall was 0.2 inch in downtown Denver.  This was the only measurable snowfall of the month and resulted in 0.01 inch of melted snow…the only measurable precipitation of the month.

In 1964…high winds blew down a sidewalk cover where a building was under construction…injuring a young woman. Three men were injured when a brick wall at a construction site toppled on them.  All were treated for face…leg…and neck injuries.  A west-northwest wind gust to 47 mph was recorded at Stapleton International Airport.

In 1969…high winds struck Boulder with gusts to 115 mph recorded at the National Center for Atmospheric Research and 83 mph in downtown Boulder.  Schools were closed because of danger from flying debris.  Some damage and minor injuries occurred.  Northwest winds gusted to 35 mph at Stapleton International Airport.

In 1985…bitterly cold weather froze pipes and cars and forced some schools to close across metro Denver.  Minimum temperatures dipped to as low as 15 below to 20 below zero across metro Denver.  The low temperature was 15 below zero at Stapleton International Airport.

In 1963…high winds struck metro Denver.  The strong Chinook winds reached 101 mph in Littleton…80 mph in Denver…and 90 mph at Rocky Flats.  Among the hardest hit areas were Boulder where buildings under construction were blown down…porches and roofs blown off buildings…and power lines damaged.  Damage totaled 100 thousand dollars in Boulder alone.

In other areas…utility lines were damaged and many signs…antennas…and road markers were blown down.  At Stapleton Airport…west winds gusted to 44 mph on the 31st and 66 mph on the 1st.  The Chinook winds warmed maximum temperatures to 65 degrees on the 31st and to 70 degrees on the 1st.


In 1963…warm weather that began with the strong Chinook winds on the 31st and 1st continued through the 8th. Maximum temperatures through the period ranged from 52 degrees on the 2nd to 76 degrees on the 5th…which was a new record high for that date.


In 1899…a protracted cold spell lasted almost two weeks. Low temperatures plunged below zero on all days but February 9th with a reading of 6 degrees.  The coldest low temperature of 22 degrees below zero on February 6th was a record low for the date.  Low temperatures of 20 degrees below zero occurred on both February 11th and 12th… But only the 11th remains as the record minimum for the date.  High temperature of only 5 degrees below zero on February 11th was a record low maximum for the date.  High temperatures climbed to only zero degrees on both February 2nd and 3rd…but were not records.

Intermittent light snow or flurries fell during the period.  The most snowfall…2.0 inches…occurred on February 2nd.


In 1904…northwest winds were sustained to 51 mph with gusts to 60 mph.  The Chinook winds warmed the temperature to a high of 55 degrees.

In 1907…west winds sustained to 42 mph warmed the temperature to a high of 59 degrees.

In 1932…the temperature rose from a low of 8 degrees at 7:00 am to the high of 58 degrees at 2:30 pm.  The biggest jump occurred from 16 degrees at 8:00 am to 42 degrees at 9:10 am.

In 1951…the lowest recorded temperature in February…25 degrees below zero…occurred.  The same temperature was also reached on February 8…1936.

In 1963…west-southwest winds gusted to 66 mph at Stapleton Airport where the strong Chinook winds warmed the temperature to a maximum of 70 degrees.

In 1970…snowfall of 0.3 inch contained only 0.01 inch of melted snow.  This was the only measurable snow and precipitation for the month…making it the driest and least snowiest February on record.  Snowfall also was only 0.3 inch on February 22-23…1992…equaling the least snowiest February.

In 1980…high winds occurred in the foothills.  Wind gusts to 75 mph were reported at Wondervu.  Northwest winds gusted to 32 mph at Stapleton International Airport.

In 1995…a short blast of early morning winds near the foothills produced a gust to 64 mph at Rocky Flats in northern Jefferson County.  Winds gusting to 59 mph in Lakewood downed a few tree branches in residential areas. West winds gusted to 37 mph at Stapleton International Airport where the warm winds kept the temperature from falling below 43 degrees…setting a new record high minimum for the date.  The temperature climbed to a non-record high of 63 degrees.


In 1934…light Chinook winds warmed temperatures to record levels on both days.  Record maximum temperatures reached 73 degrees on the 1st and 74 degrees on the 2nd. West winds were sustained to 18 mph on the 1st.


In 1996…cold arctic air plunged temperatures below zero for more than 35 consecutive hours from late on the 1st until sunrise on the 3rd.  The temperature warmed to only 1 degree below zero on the 2nd after a record low of 16 degrees below zero.


In 2011…a frigid arctic airmass settled into Front Range urban corridor. At Denver International Airport… Overnight low temperatures…from the 1st to the 3rd… Were 13 below zero…17 below zero and zero respectively. The icy temperatures caused pipes to crack and burst following the freeze. In Loveland…firefighters responded to more than a dozen water pipe breaks…most in fire sprinkler systems at businesses…apartments and assisted care facilities. At CU Earth Science Library in Boulder…more than 1000 books and several costumes for an upcoming production were damaged. At the county courts administration building in Jefferson County…a steady stream of water from a crack on the 5th floor… Went unnoticed on the 3rd and flooded all the floors of the administration wing overnight. As a result…much of the office equipment…furniture and carpet sustained water damage. A burst sprinkler line caused minor damage at the Platte Valley Medical Center in Brighton. The icy temperatures forced to closure of several school districts as well.


In 1985…the most bitter cold spell of the winter season brought sub-zero temperatures to metro Denver.  Daily low temperature records were broken at Denver.  The usual cold weather problems struck including stalled vehicles…jammed traffic lights…and frozen water and sewer lines.  At Stapleton International Airport…the high temperature was only 2 degrees above zero on the 1st…setting a record low maximum for the date.  Low temperatures reached 13 below zero on the 1st…12 below on the third…and 14 below on the 5th.


In 1989…one of the century’s worst doses of winter weather ravaged the entire state.  Bitterly frigid weather moved into metro Denver on the 1st as snow buried many sections of the state.

In metro Denver where 3 to 6 inches of snow fell…blowing snow and resultant poor visibilities caused a 46-car pile-up on I-25 in the middle of the city on the 4th.  During the period…2 to 3 hour delays were common at Stapleton International Airport where snowfall from the storm totaled 4.3 inches and northeast winds gusted to 30 mph on the 1st.

Intense cold accompanied the storm. Temperatures in Denver stayed below zero continuously for the best part of 3 days (3rd…4th…5th)…for a total of 69 hours.  This is the fourth longest sub-zero period on record.  Wind chill temperatures reached 50 degrees below zero.  The mercury dipped to 24 degrees below zero on the 5th…setting a record for the date.  This was the city’s coldest temperature in over 26 years.  Low temperatures dipped below zero on 8 consecutive days (2nd-9th).  High temperature of 9 degrees below zero on the 4th was a record low maximum for the date…as was the high of 5 degrees on the 5th.  Extensive damage occurred when pipes and water lines froze and broke.  Thousands of cars failed to start. On the 3rd…a 57-year-old woman died of hypothermia in an Arvada park.  Eighteen high school students were treated for hypothermia after a 2-hour ride through Jefferson County in an unheated bus.  At least 2 cases of frostbite were reported; there were undoubtedly many more.


In 1883…a protracted cold period occurred when low temperatures dipped below zero for 9 consecutive days. Low temperatures ranged from 22 degrees below zero on the 4th to 2 degrees below zero on the 1st and 6th.  High temperatures ranged from 10 below zero on the 3rd to 23 on the 9th.  Several temperature records were set that still stand today.  Record lows of 18 below and 22 below zero occurred on the 3rd and 4th.  Record low maximum readings of 2 below and 10 below zero occurred on the 2nd and 3rd.  The high of only 10 below zero on the 3rd is the coldest maximum temperature ever recorded in Denver.


In 1890…west winds were sustained to 44 mph with an extreme velocity of 45 mph.  The Chinook winds warmed the temperature to a high of 66 degrees.

In 1970…high winds caused scattered damage along the foothills from Golden north.  A garage in Boulder was demolished.  Broken windows and roof damage were reported in Golden.  Wind gusts from 60 to 100 mph were recorded in Boulder.

In 1990…a narrow band of heavy snow fell in the foothills southwest of Denver.  Up to 6 inches piled up at Waterton Canyon with 5 inches around the town of Deermont…both along the South Platte River in Jefferson County.  Snowfall was only 1.6 inches at Stapleton International Airport where north winds gusted to 30 mph.

In 1995…the second morning in a row of strong winds raged in the foothills and adjacent lower elevations.  Winds gusted between 70 and 85 mph in the foothills and 45 to 50 mph on the plains.  A tree was blown onto high voltage power lines in a west Denver suburb.  The fence that the wire landed on caught fire…but did no damage to the surrounding structures.  A southwest Denver man was injured when a wind gust blew him and the front door he was holding off a porch.  West winds gusted to 45 mph at Stapleton International Airport.  The strongest winds occurred in Georgetown where a gust to 100 mph overturned a pick-up truck camper on I-70.  The driver sustained only minor injuries.

In 2001…high winds developed briefly in the Front Range foothills.  A spotter at Georgetown lake measured a peak wind gust to 90 mph.

In 2008…lightning struck a home in Englewood during an electrically charged snowstorm.  A gas meter at the home was hit by lightning and burst into flames.  The unusual thunderstorm produced a combination of snow and graupel. The graupel was up to one half inch in diameter.  Total snow accumulations ranged from 1 to 4 inches across the southern Denver suburbs.  Snowfall was only 0.6 inch at the former Stapleton International Airport.


In 1894…6.2 inches of heavy snowfall were measured over downtown Denver.  East winds gusted to 25 mph on the 2nd.

In 1999…a powerful Chinook windstorm struck the foothills and adjacent plains.  Several locations registered wind gusts in excess of 100 mph…including: 127 mph atop sugarloaf mountain…120 mph at Lafayette…119 mph at Wondervu…104 mph at coal creek…103 mph at the Rocky Flats Environmental Test Facility and 100 mph in Louisville.  The damage associated with the windstorm was extensive.  Thirty 70-foot-tall power poles were damaged… Including several that supported high voltage lines transmitting electricity directly from generating plants. The combination of downed power poles…power lines…and trees resulted in outages for about 10 thousand residents. In Lafayette…power poles were sheared off for a mile and a quarter.  The power outages primarily affected residents in Boulder…Broomfield…Lafayette…Louisville… And Fort Lupton. In addition to the outages…high winds ripped apart several roofs in Boulder…including the roof of the Boulder County jail.  At Jefferson County Airport… Several planes were overturned and some hangars damaged or destroyed.  Damage to the airport alone was estimated at 100 thousand dollars. In southern Jefferson County… Localized ground blizzards reduced visibilities in blowing snow to less than 20 feet along U.S. Highway 285…resulting in several accidents. In Pine Junction a downed tree damaged a nearby residence…when it crashed onto the roof. In Bailey…a downed tree crushed a vehicle parked in the resident’s driveway.  Total damage estimates for the windstorm reached 3 million dollars…making it the fourth costliest on record at the time in Colorado.  Other peak wind gusts include:  97 mph at Boulder…93 mph at the National Center for Atmospheric Research Mesa Lab in Boulder… 88 mph at Nederland…86 mph at Aspen Springs…and 83 mph at Blue Mountain near Coal Creek Canyon.  West to northwest winds gusted as high as 46 mph at Denver International Airport.

January 2016 weather recap: Average temperatures, just a bit drier than normal

Thursday, February 4th, 2016 7:42am MST

January 2016’s weather was notable for only one thing – its lack of anything notable.  All in all the month failed to produce anything particularly dramatic.  While it was just a bit dry, it wasn’t by much and temperatures came in right near normal.

Only three periods of snowfall occurred during the month.  The heaviest of these was on the 7th and 8th but it only amounted to a few inches.  High and low temperatures failed to produce any extremes either.  We had a few mild days but also lacked extreme cold with no days dipping below zero.

Thornton’s average temperature for the month came in at 30.5 degrees.  This was just slightly below Denver’s long term January average of 30.7 degrees.  Officially, the Mile High City’s average was warmer than ours at 31.8 degrees.

Temperatures in Thornton ranged from a high of 68.5 degrees on the 30th down to a low of 1.1 degrees on the morning of the 1st.  Denver saw a maximum of 65 degrees on the 30th and a low of 5 degrees on the 10th.

In terms of precipitation, we recorded 0.34 inches in Thornton.  Out at the airport, Denver was wetter with 0.50 being recorded by their bucket.  The January average for Denver is 0.41 inches.

While we did see some snow during the month, no single storm was extraordinary and monthly totals came in below normal.  Average for Denver during the month is 7.0 inches.  Thornton saw 5.3 inches of the white stuff while Denver was just a bit behind at 4.6 inches.

Thornton’s Thursday remains chilly, brings more clouds

Thursday, February 4th, 2016 5:44am MST

The chill from our last storm lingers today but we should see highs right near the freezing mark. A weak system is approaching though and that will lead to increasing cloud cover and bring a slight chance for snow this evening and overnight.

We start out with clear skies but clouds will be increasing through the morning and early afternoon. Winds will be out of the south and generally light. Not much progress will be made on all that snow cover as today’s highs will top out at about 33 degrees.

The trough that moves in tonight will have minimal impact on us but it does bring a slight chance for snow from 6:00pm through the early morning hours tomorrow. There isn’t much moisture with the system though so any accumulations will be light – a trace to a half inch or so in our area.

Wednesday sees the sun return, cold temperatures linger

Wednesday, February 3rd, 2016 5:26am MST

Our most recent snowstorm has moved out leaving a blanket of white in its wake. While we will see the sun and blue skies return today, cold temperatures will also be lingering.

Partly clear skies start things out but clouds will be clearing as the day progresses and by late morning we will have mostly sunny skies above. Single digit mercury readings start the morning as we experience our coldest reading since New Year’s Day. We will be warming up but not quite making it to the freezing mark. Look for highs today in the upper 20s.

Looking at the balance of the week, gradual warming will be the primary feature. A few chances for light snow occur Thursday and Saturday night. Neither of these will amount to much though. Get the complete extended forecast here.

Thornton receives biggest snowstorm since 2012; Time lapse video captures it

Tuesday, February 2nd, 2016 3:27pm MST

And that is pretty much a wrap. Thornton totaled 12.2 inches snowfall from the two day storm.

That is our biggest single snowstorm since February 3-4, 2012 when we received 13.8 inches. Not too shabby!

Main streets and highways are mainly just wet right now, slushy in a few spots. Temperatures tonight are going to be dropping into the single digits though and that is going to make for some very slick roads overnight and tomorrow morning. If you venture out, be sure to be careful!

The video here comprises the past 27 hours as seen from our east webcam compressed to about 53 seconds. Enjoy!

As one of our coldest months, January can be a good month to hibernate inside and avoid the outdoors.  But, like any month in Colorado, photo opportunities abound as our monthly slideshow demonstrates.

Snow is not normally dominant in the month but when it does fall, it can create a beautiful blanket of white.  Throw in the amazing sunrises and sunsets we receive in the middle of winter as well as wildlife and a host of other subjects and the imagery can be quite beautiful and stunning.

  • Slideshow updated February 1, 2016

Our monthly photo slideshow is going to feature images that we have taken but more importantly images that you have captured.  The photos can be of anything even remotely weather-related.

Landscapes, current conditions, wildlife, pets, kids.  Whimsical, newsy, artsy.  Taken at the zoo, some other area attraction, a local park, a national park or your backyard.  You name it, we want to see and share it!

Images can be taken in Thornton, Denver or anywhere across the extraordinary Centennial State.  We’ll even take some from out of state if we can tie it to Colorado somehow.

We’ll keep the criteria very open to interpretation with just about any image eligible to be shown in our slideshows.

What do you win for having your image in our slideshow?  We are just a ‘mom and pop’ outfit and make no money from our site so we really don’t have the means to provide prizes.  However you will have our undying gratitude and the satisfaction that your images are shared on the most popular website in Thornton.

Storm to start winding down Tuesday morning

Tuesday, February 2nd, 2016 6:34am MST

February has certainly started out with a bang as a significant winter storm has struck. The prolonged event however is coming to an end this morning and conditions will be improving.

Early this morning roads were snowpacked and slippery but certainly not impassasble. Students are undoubtedly happy campers though as all area school districts are closed for the day.

Here in Thornton, as of 4:00am, we had recorded 10.5 inches total snowfall from the event. Some additional accumulation can be expected this morning but things have already started to ease and will truly taper off after about 8:00am. A few flurries will be possible during the day with things ended entirely by mid-afternoon or so. The Winter Storm Warning remains in effect until noon.

It will remain cold today with a high only in the mid-20s. Couple the cold temperatures with wind gusts in the teens and it will be uncomfortable outside. Skies will begin clearing this evening and that is going to lead to bitter cold temperatures overnight and early tomorrow morning. Look for overnight lows around 7 degrees with wind chill temperatures dipping below zero.

Live social feed: Significant winter storm to close January, begin February

Monday, February 1st, 2016 5:35am MST

ThorntonWeather.com on Facebook, Google+ and TwitterA significant winter storm is bearing down on Colorado and the state is blanketed with watches and warnings. The system has the potential to deliver our biggest snowfall of the 2015 / 2016 season thus far.

The National Weather Service has said 6 to 12 inches will be possible between Sunday night and Tuesday morning. Areas north of I-76 like Thornton will likely be at the lower end of the range but even at that it would be a healthy shot of snow.

Throughout the period we will of course be monitoring the system and posting regularly to our Facebook page and Twitter feed.  You can follow along in real time below.  We are also on Google+ here.

For comprehensive look at the storm, please monitor our Winter Weather Briefing page.
