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

As we pointed out in our April weather preview, the month can bring just about any type of weather condition and we see that in our look back at this week in Denver weather history. From powerful, damaging winds to Arctic cold to heavy snowfall this has been an eventful week in the past.

From the National Weather Service:

31-2

In 1980…the second major blizzard in 5 days buried much of eastern Colorado under 6 to 12 inches of snow. Some drifts were up to 22 feet high. Hundreds of travelers were stranded. Over 3000 families were without power. Livestock losses were high. Metro Denver escaped the main brunt of this storm. At Stapleton International Airport…only 6.3 inches of snow fell over the 3-day period and north winds gusted to only 22 mph on the 1st.

31-3

In 1979…total snowfall of 6.6 inches was measured at Stapleton International Airport where north winds gusted to 31 mph on the 31st. The greatest accumulation of snow on the ground was 3 inches on the 1st.

31-4

In 1905…much rain and some snow occurred over the 5 days behind an apparent cold front. Precipitation totaled 2.00 inches. There was a thunderstorm on the 3rd. Snowfall totaled 3.0 inches on the 4th. North winds were sustained to 34 mph on the 1st and 2nd and to 30 mph on the 3rd. High temperatures during the period ranged from the upper 30’s to the lower 40’s. Low temperatures were in the upper 20’s and lower 30’s.

In 1987…a vigorous cold front produced 2.3 inches of snowfall at Stapleton International Airport where northeast winds gusted to 39 mph. The temperature dropped from a maximum of 59 degrees at mid-morning to a low of 25 degrees at midnight.

1-2

In 1963…strong winds buffeted metro Denver…while wind- whipped fires consumed grassland on the plains. A child was injured by a windblown falling tree in Castle Rock. Southwest winds gusted to 52 mph at Stapleton Airport… Causing some blowing dust. The worst fire storm burned over 25 thousand acres of grazing land in southern Weld County near Roggen northeast of Denver.

In 1984…a snowstorm with near-blizzard conditions over eastern Colorado closed many roads…including I-70 and I-76 east of Denver and I-25 between Denver and Colorado springs. At Stapleton International Airport…snowfall totaled only 2.5 inches…but north winds gusted to 45 mph on the 2nd.

In 1999…moist upslope conditions allowed heavy snow to develop in the Front Range foothills where snowfall totals included: 10 inches at Aspen Park and Evergreen; 9 inches at Turkey Creek; 8 inches at Idaho Springs and Genesee; 7 inches at Aspen Springs…Crow Hill…Intercanyon…and Lake George. In metro Denver snowfall totals included: 10 inches south of Sedalia; 8 inches in Littleton; 7 inches at Morrison; 6 inches at Highlands Ranch; and 4 to 5 inches in Northglenn…Parker and near Louisville. Snowfall totaled 4.7 inches at the site of the former Stapleton International Airport.

1-3

In 1945…snow fell across metro Denver for a total of 51 consecutive hours. While the storm was not accompanied by excessive snow…the long duration made the event a heavy snow producer. Snowfall totaled 10.7 inches in downtown Denver with 9.5 inches recorded at Stapleton Airport. North winds were sustained to 21 mph on the 1st; otherwise winds were not strong. The air mass was very cold for April. The high temperatures of 26 on the 2nd and 17 on the 3rd were record low maximums for the dates. The latter was also a record low maximum for the month. Warm weather following the storm quickly melted the snow.

In 1973…heavy snow fell at Stapleton International Airport where 8.7 inches were measured. Snow began late on the 1st and continued through early morning on the 3rd. Thunder accompanied the snow during the late morning and afternoon of the 2nd. North winds gusted to 33 mph on the 2nd and 37 mph on the 3rd. Snow only accumulated to a depth of 5 inches on the ground due to melting.

In 1977 a foot of snow fell in Boulder and Broomfield. The Denver-Boulder turnpike was closed for an hour after numerous minor traffic accidents. At Stapleton International Airport…snowfall totaled 4.7 inches and southeast winds gusted to 32 mph on the 2nd. The greatest depth of snow on the ground was only 3 inches due to melting.

In 1894…northwest winds were sustained to 42 mph with gusts to 48 mph. The warm Chinook winds warmed the temperature to a high of 70 degrees.

In 1925…north winds were sustained to 40 mph with gusts to 42 mph.

In 1957…a heavy snow storm dumped 17.3 inches of snow at Stapleton Airport. Strong gusty north winds to 31 mph reduced visibilities to 1/8 mile at times and created blizzard conditions. The 24-hour snowfall had been exceeded only twice in previous records…and the 24 hour precipitation of 2.05 inches was the third heaviest of previous record during April.

In 1959…a cold front produced strong gusty winds across metro Denver. North winds gusting to 50 and 60 mph caused some minor damage to power lines and signs and caused dust storms on the plains east of Denver. A wind gust to 49 mph was recorded at Stapleton Airport.

In 1966…northwest winds gusting to 52 mph produced blowing dust…which briefly reduced the visibility to 1 mile at Stapleton International Airport.

In 1975…the all-time lowest recorded temperature in April… 2 degrees below zero…occurred. This is also the latest below zero reading for the season.

In 1982…a strong windstorm struck all of metro Denver… Causing minor damage. Wind gusts to 127 mph were recorded at Rocky Flats south of Boulder…116 mph at Wondervu…100 mph at Jefferson County Airport in Broomfield…and 56 mph at Stapleton International Airport. The strong winds whipped up blowing dust…briefly reducing the visibility to 3/4 mile.

In 1986…heavy thunderstorms produced wind gusts to about 70 mph in Boulder. A severe thunderstorm wind gust to 62 mph was recorded at Stapleton International Airport. The strong winds kicked up thick clouds of blowing dust severely restricting surface visibility.

In 1997…a pacific storm left heavy snow in the foothills with lesser amounts across the city. Snowfall totaled 12 inches near Blackhawk…11 inches at Golden Gate Canyon…10 inches at Conifer and Crow Hill…9 inches at Evergreen…5 inches at Sedalia…and 4 inches at Castle Rock and Morrison. Only 2.1 inches of snow fell at the site of the former Stapleton International Airport. Northwest winds gusted to 21 mph at Denver International Airport.

In 1998…a major spring storm brought heavy snow to metro Denver and the foothills. Snowfall totals ranged from 12 to 22 inches in the foothills with 4 to 12 inches across metro Denver. Snowfall totals included: 22.5 inches near conifer; 13 inches in Coal Creek Canyon; 12 inches near Blackhawk…Eldora…and Genesee; 10 inches near Evergreen and Nederland; 9 inches in Lakewood; 8 inches in Broomfield and northwest Denver; and 7.0 inches at the site of the former Stapleton International Airport. Northeast winds gusted to 31 mph at Denver International Airport.

In 2002…snowfall was only a trace at the site of the former Stapleton International Airport. This was the only snowfall of the month…ranking the month…along with previous months… The 2nd least snowiest on record.

2-3

In 1955…strong west to southwest winds raked metro Denver on both days. Sustained winds as high as 37 mph with gusts to 60 mph were recorded at Stapleton Airport where the visibility was reduced to 1/4 mile in blowing dust.

In 1974…a heavy snowfall of 6.7 inches was accompanied by northeast wind gusts to 33 mph which produced some blowing snow across metro Denver. Over eastern Colorado many highways and schools were closed due to near-blizzard conditions from the storm.

In 1986…the worst snow storm of the season blasted metro Denver. Heavy snow and high winds combined to close roads… Schools…and airports. Portions of all interstate highways out of Denver were closed at times. The snow came after an exceptionally mild late winter and early spring; trees and bushes had already bloomed and leafed out. The snow and wind snapped many of these…causing power outages. Total snowfall amounts in metro Denver ranged from 1 to 2 feet with 2 to 3 feet in the foothills. Snowfall totaled 12.6 inches at Stapleton International Airport where north winds gusting to 39 mph reduced the visibility to 1/8 mile in snow and blowing snow. Most of the snow fell on the 3rd when temperatures hovered around 30 degrees for most of the day. The heavy snow halted traffic and closed businesses. A 59- year-old man was found dead from exposure in northwest Denver. The roof of a toy store in Northglenn collapsed. A 100 thousand square foot section of a greenhouse roof collapsed in Golden…destroying over a million dollars worth of plants.

In 2000…a combination of strong instability and moist upslope winds allowed for a heavy…wet spring snowstorm to develop in and near the Front Range foothills. The heaviest snow occurred in southern Jefferson County. Storm totals included: 14 inches near Conifer…12 inches near Evergreen and on Floyd Hill; 11 inches near Blackhawk…Morrison…and tiny town; 10 inches at Aspen Springs and Eldora Ski Area; 9 inches at Chief Hosa; and 8 inches at both Golden Gate Canyon and Rollinsville. Only 2.1 inches of snow fell at the site of the former Stapleton International Airport. North winds gusted to 36 mph at Denver International Airport on the 2nd.

In what may mean an end to all those frustrating and dangerous weather conditions that plague the planet, today Google announced Google Wind, a ground-breaking weather control system.  Now in use in the Netherlands, the system has brought an end to the windy and cloudy conditions in that nation.  This will surely have an impact across the globe soon.

Happy April Fools’ Day.

April marks a transition between winter and summer for most of the country but for Denver it is especially true as we can see a stunning variety of weather.

The proverbial April showers are certainly a possibility for Denver. Snow? Tornadoes? Thunderstorms? You bet – all can happen!

For good measure throw in a chance for hail and even dust storms and April gives every type of weather condition you could like – or hate.

It has been a while since we have seen any snow, more than a month in fact, but Mother Nature is going to try to fix that over the next 36 hours. Models are however trending toward a less significant event than originally expected.

For today we start out with mostly cloudy skies and can expect that to fill in by late morning and be cloudy. Temperatures will be topping out in the low to mid-40s by early afternoon. Winds will become a bit breezy this afternoon through tonight.

• Stay up to date with Thornton’s weather: Be sure to ‘like’ us on Facebook, follow us on Twitter and add us to your Google+ circles.

In terms of precipitation, some light sprinkles of rain will be possible through early to mid-afternoon. After that, coverage should increase falling initially as rain then mixing in a few snowflakes in the evening followed by a turn to all snow around midnight. Overnight temperatures will drop to near freezing.

Snow looks to continue until about 8:00am Saturday then as it warms move back to rain. By noon tomorrow precipitation will begin to ease up and late afternoon and the evening should only have a few sprinkles, maybe a few flakes of snow mixed in late.

As we mentioned, models are pointing to a more southward track for this system which means less of an impact than thought just 24 hours ago. Here in Thornton, we are likely looking at a total of 1 to 3 inches from the event. Areas to our south and west will get more.

Overnight Saturday the skies will begin to clear and temperatures will dip below freezing. Sunday rebounds nicely with mostly sunny skies and temperatures in the mid to upper 50s.

Have a great weekend and keep an eye on http://www.thorntonweather.com/ for all the latest with the coming storm.

Be sure to get out and enjoy the weather today as it is going to be the most pleasant day of the entire week. After today, unsettled conditions return and will bring cooler and wetter conditions.

For today we start out with mostly clear skies and that will be the general rule throughout other than a few more clouds later in the day. Temperatures will be warming to a very pleasant high of 66 degrees. Tonight temps dip to the mid to upper 30s and we stand a chance to see a few rain showers, mainly after midnight, as our next storm system begins to make itself felt.

As for what lies ahead after today, check out the extended forecast here.

The month of March is the start of meteorological spring and while conditions do begin warming, winter weather is certainly out of the question.  From hot to cold, snow to rain, the conditions can be very conducive to great pictures as we see in our slideshow.

March in Denver typically means frequent and rapid weather changes. The days grow longer and we start enjoying more sunshine and sometimes summer-like weather. However, on occasion arctic air masses can still force their way south into Colorado dropping temperatures quickly and markedly.

With the active wildlife, increased outdoor activities by us humans, and of course the weather, March imagery contains a wide variety of subjects and extremes.

• Slideshow updated March 30, 2017. To learn more about how to send your photo to us for inclusion in the slideshow, see below the slideshow.

Showcasing images captured by ThorntonWeather.com readers as well as some of our own, our monthly slideshow covers the entire gamut of weather-related imagery.

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.

Following a respectable bit of rain overnight, showers are beginning to end and we will start to dry out by later this morning. The dry conditions will be short-lived though as our next storm system arrives on Friday.

This morning we will see some sprinkles continue until about 11:00am or so. By then we should see the cloud cover ease and by mid to late afternoon partly sunny skies return. Temperatures will be warming up to a high in the mid-50s, just a bit below normal.

Tomorrow we return to unseasonably warm temperatures with highs well into the 60s and dry conditions. Friday and Saturday see a return to unsettled condition bringing chances for rain and perhaps, finally, some snow. See our extended forecast for more.

We had been hoping for some precipitation and we are certainly going to see it over the next 36 hours or so. Sprinkles start things off and it will be relatively quiet during the daytime but this evening and tonight we should receive a good soaking.

We start out the day with mostly cloudy skies and by mid-afternoon any sun should be pretty much done for the day. Temperatures will be on the cool side today with highs topping out around 50 degrees, about 8 degrees below normal.

As for the rain, sprinkles / light rain will be possible through the morning and first part of the afternoon. If we get enough daytime heating, a bit of thunder could be thrown into the mix this afternoon. By late afternoon and particularly this evening, we should see showers become widespread as deeper moisture arrives.

The rain will continue into the pre-dawn hours before starting to taper off. Overnight lows tonight will be in the mid-30s and winds will be a bit breezy. Right now we are not expecting to see any of this moisture fall as snow in our area, primarily due to a lack of cold air. There may be a few flakes that get mixed in though early tomorrow morning.

Have a great day!

March 26 to April 1: This week in Denver weather history

Up until a few days ago, our March had been extraordinarily dry and warm. That isn’t always the case, particularly when it comes to snowfall.  March is one of our snowiest months and our look back at this week in Denver weather history shows a number of notable snowfall events.

From the National Weather Service:

24-26

In 1959…the second major spring storm in less than a week dumped 10 to 20 inches of wet snow across northeastern Colorado. Snowfall totaled 14.3 inches at Stapleton Airport where north winds gusted to 36 mph…causing near- blizzard conditions with visibilities frequently reduced to 1/2 mile in snow and blowing snow. Many travelers were marooned when trains…planes…and buses were unable to make their schedules. Utility lines were again damaged as a result of the storm.

25-26

In 1899…a major storm dumped 13.1 inches of heavy snow over downtown Denver. Rain changed to snow around mid- morning on the 25th. Snowfall became heavy and continued until late evening on the 26th. North to northeast winds gusted to 30 mph on both days. The cold air mass plunged temperatures from a high of 55 degrees on the 25th to a low of 8 degrees on the 26th.

In 1995…a potent early spring storm produced heavy snow in the mountains…but skipped over metro Denver…before producing blizzard conditions and 6-foot drifts over eastern Colorado…causing the closure of I-70 and other highways. Only 0.7 inch of snow fell at the site of the former Stapleton International Airport. North winds gusted to 40 mph at Denver International Airport on the 25th.

In 2001…a persistent band of moderate to heavy snow showers with a few embedded thunderstorms formed in the foothills around Estes Park and spread to the southeast across Boulder and Denver and on the plains to the east of Denver. Thunder and snow was reported at Jefferson County…Centennial…and Denver International Airport during the evening of the 25th. Snowfall totals included: 7 inches at Boulder and Louisville; 6 inches at Broomfield…Niwot…and Westminster; 5 inches at Eldorado Springs…Nederland…and near Strasburg. Only 2.1 inches of snow fell at the site of the former Stapleton International Airport.

25-27

In 1904…heavy snowfall totaled 7.0 inches in downtown Denver.

26

In 1899…a major winter storm dumped 11.3 inches of snow over downtown Denver.

In 1910…west winds were sustained to 42 mph. A snow shower produced a trace of snow.

In 1935…a severe dust storm swept across the city. The dense dust blew in on a gale from the east-northeast. The dust “bank” was first visible on the northeastern horizon at about 2:00 pm. It advanced toward the city as a rolling…swirling…yellowish-to smoke-black cloud. At 2:06 pm…the cloud of dust enveloped the station. Before the storm the visibility was unlimited. At 2:08 pm…the visibility was reduced to 1/8th mile. By 2:25 pm…the visibility was increasing and was above 1000 feet at 3:10 pm. Thereafter…the sun appeared as a dim “ball of fire” at times. The dust was partially gone at 8:30 pm. During the storm…northeast winds were sustained to 32 mph with gusts as high as 35 mph.

In 1971…the highest recorded temperature in March…84 degrees…occurred. This was the highest temperature recorded so early in the season. Previously…84 degrees had not been reached until April 21st. The temperature also exceeded the previous daily record of 75 degrees set in 1960. Strong northwest Chinook winds gusting to 37 mph at Stapleton International Airport were partially responsible for causing the extremely warm weather so early in the season.

In 1985…strong winds occurred along the foothills. A wind gust to 76 mph was recorded in Boulder. A dust storm produced by the strong winds caused a 35-car pileup on I-25 north of Denver. In Denver…the high winds blew out windows in a few downtown buildings. West winds gusted to 52 mph at Stapleton International Airport.

In 1993…strong winds from high based thunderstorms blew a roof off an Englewood business onto several parked cars. The winds also caused half of a furniture warehouse roof to collapse in north Denver…ripped a mechanical shed off the roof of a building in downtown Denver…and downed power lines in Commerce City. Wind gusts ranging from 55 to 68 mph were recorded. At Stapleton International Airport… Where no thunder was heard…a microburst wind gust to 55 mph briefly reduced the visibility to zero in blowing dust.

In 1994…heavy snow fell in the foothills west of Denver and over the palmer divide to the south of metro Denver. Snowfall totaled 11 inches at both the Eldora Ski Area and at Idaho Springs. Only 1.3 inches of snowfall were measured at Stapleton International Airport where north winds gusted to 28 mph.

In 2006…post-frontal strong winds quickly dissipated the dense morning fog across metro Denver. West to northwest winds were strong and gusty from mid-morning until sunset. West winds were sustained to 37 mph with gusts to 52 mph at Denver International Airport.

26-27

In 1886…heavy snowfall totaled 7.1 inches in downtown Denver.

In 1911…post-frontal north winds were sustained to 48 mph on the 26th and to 47 mph on the 27th.

In 1931…a cold front brought snow and very cold weather to the city. Snowfall totaled 7.3 inches over downtown Denver with most of the snow…6.4 inches…occurring on the 26th… When northwest winds were sustained to 38 mph with gusts to 44 mph. High temperature of 31 degrees on the 26th equaled the low temperature of the previous day as the temperature plunged to a low of 1 degree below zero. High temperature of only 15 degrees on the 27th was a record low maximum for the date. Low temperature of 2 degrees below zero on the 27th was not a record.

In 1975…a major pre-Easter blizzard…the worst since the vicious storm of 1949…battered northeastern Colorado and left livestock losses in millions of dollars…but metro Denver escaped the main brunt of the storm and received only 5.0 inches of snowfall. North winds gusted to 38 mph at Stapleton International Airport where temperatures plunged from a high of 50 degrees to 18 degrees by midnight on the 26th.

In 1991…heavy snow fell over portions of the eastern foothills with 9 inches recorded at Lake Eldora west of Boulder. The snow spread across metro Denver…but snowfall totaled only 1.7 inches at Stapleton International Airport where north to northeast winds gusting to 31 mph on both days produced some blowing snow.

Following a relatively pleasant day Monday, we then enter an unsettled period that will last into the weekend. The good news is that we see decent chances for much-needed precipitation at different points of the week.

For today, we start out under partly sunny skies that will be with us through the morning. Then, this afternoon, cloud cover will slowly increase. Temperatures will be heading toward a high in the low 60s, a bit above the average for the date of 57 degrees.

Daytime hours will be dry then this evening we begin to see a chance for light rain showers and those same chances will stick around until Tuesday evening when precipitation chances increase. Overnight lows tonight will be in the upper 30s.

Taking a quick look at the rest of the week, cooler temperatures a bit below normal will be on tap Tuesday and Wednesday. Precipitation chances increase on both days with the best chances coming Tuesday night. Thursday we get a bit of a break with a day similar to today then our next system arrives for Friday and Saturday bringing cooler temps and more chances for precipitation.
