This Week In Denver Weather History

February 19 to February 25: This Week in Denver Weather History

Damaging winds are not uncommon along the Colorado Front Range, particularly this time of year when strong Bora and Chinook winds can rage. We see a number of such events in our look back at this week in Denver weather history. Also making an appearance are a number of notable snow and cold events.

From the National Weather Service:

17-19

In 2006…a cold spell resulted in 4 temperature records. Low temperatures of 10 degrees below zero on the 17th… 13 degrees below zero on the 18th…and 4 degrees below zero on the 19th were record minimums for those dates. The high temperature of only 7 degrees on the 18th was a record low maximum for the date. Light snow fell on the 17th…but totaled less than half an inch at Denver International Airport.

18-19

In 1954…a vigorous cold front produced north winds gusting to 56 mph and a trace of snowfall at Stapleton Airport on the 18th. Strong and gusty winds to 55 mph persisted through the next day and caused some blowing dust.

In 1955…a storm dumped heavy snow across metro Denver. At Stapleton Airport where north winds sustained to 28 mph produced some blowing snow…snowfall totaled 8.8 inches.

18-20

In 1913…post-frontal snowfall totaled 6.9 inches in downtown Denver over the 3 days. Most of the snow fell on the 19th. Northeast winds were sustained to 21 mph with a measured extreme velocity to 24 mph on the 18th.

In 1924…light snowfall totaled 4.6 inches over the 3 days. This was the only measurable snowfall of the month. High temperatures plunged from 45 degrees on the 18th to 17 degrees on the 20th. Low temperatures dipped from 31 degrees on the 18th to only 8 degrees on the 20th. Northeast winds were sustained to 24 mph on the 19th.

In 1953…a major blizzard dumped 10.6 inches of snowfall at Stapleton Airport. Strong north winds at sustained speeds of 25 to 35 mph with gusts as high as 44 mph frequently reduced visibilities to 1/4 mile in blowing snow during the day of the 19th. The strong winds caused much drifting snow…making accurate snowfall measurements almost impossible. Precipitation from the storm totaled 1.13 inches. The 1.01 inches of precipitation on the 19th was the greatest calendar day and 24 hour precipitation ever recorded in the city during the month of February.

In 1987…large amounts of new snow fell in the Front Range foothills. The foothills received 10 to 20 inches of new snow with 4 to 8 inches on the adjacent plains. On the 19th…flight delays occurred at Stapleton International Airport where snowfall totaled 4.2 inches and east winds gusted to only 18 mph on the 19th. Schools were closed in the foothills above Boulder.

In 1899…northwest winds sustained to 42 mph with gusts to 45 mph warmed the temperature to a high of 56 degrees… The highest reading of the month that year.

In 2007…this was the last day of 61 consecutive days with snow cover of 1 inch or more in Denver. This second longest period of snow cover on record began with the blizzard on December 20-21…2006…when 20.7 inches of snow fell at the site of the former Stapleton International Airport where official snow measurements were taken. Additional snowfall during December…January…and February prolonged the event. Snow depth on the ground was measured to the nearest inch once daily at 6:00 am MST.

19-20

In 1937…post-frontal heavy snowfall totaled 8.4 inches over downtown Denver. Most of the snow…6.6 inches…fell on the 20th when north winds were sustained to 16 mph with gusts to 18 mph. The temperature dipped to a low of 9 degrees on the 20th.

In 1939…post-frontal snowfall totaled 5.4 inches in the city. The snow covered streets and highways with a coating of ice as the temperature fell from 36 degrees at 2:00 pm on the 19th to a low of 4 degrees at 3:00 am on the 20th. Many motorists were marooned for several hours. Northeast winds were sustained to 24 mph on the 19th.

North winds at sustained speeds of 20 to 30 mph with higher gusts persisted throughout the day…producing much blowing snow. East of the city…winds gusting 40 to 80 mph caused blizzard conditions and produced drifts 2 to 4 feet high.

In 1981…a vigorous cold front at midday produced strong northeast winds at 20 mph with gusts to 30 mph and billows of blowing dust reducing the visibility to 3 miles during the afternoon. Even stronger winds from the north at 25 mph with gusts to 45 mph in snow and blowing snow reduced the visibility to 1/4 mile during the evening. Snowfall totaled only 2.6 inches at Stapleton International Airport.

20-21

Thronton’s weekend continues warm trend, brings slight chance for showers at the end

Friday, February 17th, 2017 5:08am MST

The unseasonably warm weather we have been experiencing is going to continue Friday and through the weekend. We will see more clouds and Sunday brings a slight chance for showers but overall warm, calm conditions will be the main features.

For Friday we will have mostly sunny skies with a few clouds due to some upper level moisture. Conditions will be dry and calm. Highs today will reach the mid-60s and then we will dip to the mid-30s overnight.

Increasing mid and upper level moisture leads to a good bit more cloud coverage Saturday. We will however remain dry and see temperatures once again reach the low to mid-60s. Saturday night into

Sunday morning lows will drop to around 40 degrees. Sunday starts out calm with a good bit of sun but then clouds will increase. There will be just a slight chance for some rain showers from late morning / early afternoon through Sunday night. Highs Sunday will again be in the low to mid-60s.

Have a great weekend!

Denver sets record high temperature for February 16, third high temp record of the month

Thursday, February 16th, 2017 4:53pm MST

Record High TemperaturesFor the second day in a row and the third time during February 2016, the Mile High City set a daily high temperature record.

At 2:59pm Denver International Airport topped out at 75 degrees.  This easily bested the previous record high temperature for February 16 of 70 degrees set in 1970.  Here in Thornton we matched Denver’s high with 74.7 degrees coming at 2:35pm.

Yesterday Denver’s high temperature reading of 67 degrees broke the high temperature for that date (previously 66 degrees in 1986).  On February 10th, Denver reached 80 degrees making it not only the warmest reading for that date but also the warmest February temperature ever recorded.

Record-setting warmth on tap for Thornton’s Thursday

Thursday, February 16th, 2017 4:58am MST

The stage is set for us to set our third record high temperature this month. High pressure is dominating the scene right now and with clear skies the mercury is going to climb.

We start out the day with clear skies and those will continue throughout the day. Temperatures will be climbing from morning lows in the 30s to a high around 73 degrees. The record high for today’s date is 70 degrees set in 1970 and that is virtually certain to fall. Otherwise, look for overall conditions to be dry and calm.

Tonight mostly clear skies will be above and we will cool to overnight lows in the mid-30s.

Our live weather gauges will allow you to keep an eye on the rising mercury.

Wednesday, February 15th, 2017 5:04am MST

Following a chilly start to the day we will be warming up quite nicely. Temperatures will be well above normal as we enjoy a spring-like day.

We start out the day with clear skies and other than a few, high clouds there will be sunshine throughout. Temperatures start out below breezing but then we will be warming up to the mid-60s. Average for the date is 46 degrees so we will easily be above that. Winds will be relatively light and out of the south.

Overnight tonight the skies remain clear and temperatures will drop to the mid-30s.
