March 2016 weather recap: A bit warmer than normal, much wetter and snowier
The month of March 2016 in Thornton was a bit of a tale of two halves. The first, mild and dry. The second, colder and much, much wetter.
We started out with above normal temperature readings dominating the daily temperatures. In fact 12 of the first 14 days of the month saw high temperatures above average, some well above. Other than a nice bit of rain on the 7th, those first two weeks were dry as well. All were courtesy of strong high pressure staying over the region.
Things cooled down briefly for the next few days and we received a nice bit of snow on the 17th and 18th. However, warm weather returned with back to back 70+ degree days on the 21st and 22nd.
March is however our snowiest month and Mother Nature delivered a walloping reminder of that on the 23rd. Blizzard conditions arrived early in the morning and persisted through the day. Schools and businesses shuttered as did the airport and major interstates.
Cool, unsettled weather conditions finished out the month. Another, light show of snow came on the 26th followed by flurries on the 31st.
Thornton’s overall average temperature for March was 41.4 degrees. This was very close to Denver’s official measurement of 41.6 degrees as taken out at DIA. The average monthly temperature for March is 40.4 degrees.
Thornton saw a maximum mercury reading of 72.4 degrees on the 21st and a low of 13.5 degrees on the 24th. Out at the airport, Denver saw its highest reading of 74 degrees on the 11th and a low of 10 degrees on the 24th.
In terms of precipitation, rain and snow combined to bring Thornton a wet 3.21 inches. The long term average for Denver in March is 0.92 inches.
Denver’s automated system claims a mere 0.90 inches of liquid precipitation at the airport. It is clear that they had a very incorrect reading from the blizzard on the 23rd. Their climate report for the month makes the note, “the precipitation for March 23rd is too low due to undercatch from blizzard. This value is under review. This could change the values below.”
Snowfall was abundant for the month and far exceeded the average of 10.7 inches for Denver. Here in Thornton we received 30.1 inches – our second highest monthly total in 10 years. The airport lagged considerably due to their location out in the middle of nowhere with 18.4 inches.

Thornton’s April weather preview: Expect just about anything
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.
April 3 to April 9: 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:
31-3
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.
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.
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 2014…a storm system brought moderate to heavy snow to the Front Range Mountains…Foothills and Urban Corridor. Storm totals in the mountains and foothills included: 21.5 inches…8 miles north of Blackhawk; 15.5 inches near Rollinsville; 15 inches at Aspen Springs; 14.5 inches near Ward; 12 inches…6 miles southwest of Evergreen; 11 inches at Cabin Creek and 12 miles south-southwest of Georgetown; 10 inches at Winter Park; 8 inches near Conifer…Georgetown and Gross Reservoir; with 7.5 inches at Bailey and Intercanyon. In the Urban Corridor…storm totals included: 9.5 inches near Highlands Ranch…7 inches at Boulder… 6 inches near Castle Rock…with 5.5 inches at Lakewood and near Morrison. At Denver International Airport…3.4 inches of snowfall was observed.
2-4
In 1934…snowfall totaled 8.2 inches in downtown Denver from the afternoon of the 2nd through the early morning of the 4th. Most of the snow…6.8 inches…fell on the 3rd. Rain changed to snow behind a strong cold front on the afternoon of the 2nd. The cold front first appeared as a long-cigar shaped squall cloud to the north of the city. Strong north winds at sustained speeds of 33 mph with gusts to 43 mph produced much blowing dust and an abrupt fall in temperature…from a high of 68 on the 2nd to a low of 22 on the 3rd.

3
In 1872…skies were cloudy and threatening until 11:30 am when it commenced to rain and continued to rain until 3:00 pm…when it turned into heavy snow with a very brisk north wind. Snow continued all night. Telegraph wires were downed between Denver and Cheyenne…and the night report could not be sent. Precipitation (rain and melted snow) measured 0.82 inch.
In 1887…north winds were sustained to 43 mph.
In 1894…northwest winds were sustained to 41 mph with gusts to 50 mph. The warm Chinook winds on the 2nd became a Bora as the temperature warmed to a high of only 52 degrees.
In 1900…southeast winds were sustained to 52 mph with gusts as high as 61 mph.
In 1945…the temperature warmed to only 17 degrees…the all-time record low maximum for the month.
In 1968…a snow storm of unusual severity for so late in the season caused ground blizzard conditions with near zero visibility in snow at times and severe drifting of snow over portions of northeastern Colorado and metro Denver. Highways were blocked to the north of Denver and to Colorado springs. Rain at the start of the storm contributed to power and communications outages. In metro Denver…snowfall totaled 7.0 inches at Stapleton International Airport where north winds gusted to 45 mph.
In 1978…a tornado was sighted by a national weather service observer 3 miles north of Stapleton International Airport near the rocky mountain arsenal. Security police on the arsenal called it a large dust devil…but four commercial airline pilots confirmed the phenomenon as a tornado or funnel cloud.
In 1981…a snowstorm hit northeastern Colorado…dumping 6 to 12 inches of snow in the foothills and 4 to 8 inches on the plains north of Denver. Snowfall totaled only 2.0 inches at Stapleton International Airport where north winds gusted to 24 mph.

March 2016 top shots: Monthly photo slideshow
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 31, 2016. To learn more about how to send your photo to us for inclusion in the slideshow, see below the slideshow.

Mild temps, slight chance for thunderstorms Tuesday; snow possible overnight
Thornton’s Tuesday looks to be a relatively pleasant day with mild temps but with some cloud cover. We also will see a return to wintry weather tonight through tomorrow although it won’t be anything too dramatic.
For today we start with partly sunny skies and we will see a good little bit of cloud cover throughout the day, increasing in the afternoon. Temperatures will be climbing to a pleasant high of 63 degrees.
The next storm system starts making itself felt this afternoon although for the most part, its effects will be limited in our area as it will be mainly to our north. We do see a slight chance for some thunderstorms and shower activity from about 3:00pm through midnight tonight.
As temperatures drop overnight, light snow will be possible in the early morning hours through much of the day tomorrow. Accumulations will be quite light though, perhaps an inch or two for the entire event. The good news is that while temperatures will be cool for the balance of the workweek, they will rebound nicely for the weekend. Get the extended weather forecast here.
Time lapse video: Thornton’s March 2016 blizzard
It is hard to believe so much snow can fall over such a short period of time. Over just more than 12 hours Thornton received 21.7 inches – our biggest snowstorm since 2006. Our east facing webcam captured all the action from start to finish.
The video below starts at midnight on the 23rd with dry conditions. By about 2:00am rain falls but that quickly transitions to snow.
It is after daybreak that the storm gets started in earnest and the heavy snowfall almost entirely obscures the view at points. As is typical in Colorado, by mid-afternoon, we actually start to see some blue skies.
The video covers 19 hours in about 39 seconds. There are a few ‘hiccups’ in the video that you might notice. These were when we had brief power outages.
March 27 to April 2: This week in Denver weather history
With March being historically our snowiest month we would expect to see plenty of snow events this week in Denver weather history and we do indeed. Also notable however is the other extreme – that of dangerously dry conditions. We see one event, in 1963, that scorched 25,000 acres of ranchland in Weld County.

To say the storm that pounded the Colorado Front Range was a big one does not do it justice. In less than 24 hours Thornton would see blizzard conditions and our second heaviest snowfall of the previous 10 years.
