Denver sets record low maximum temperature for April 13

Monday, April 13th, 2020 5:42pm MDT

Record Cold Temperatures

A second cold temperature record of the day has fallen.

The high temperature in Denver as measured at Denver International Airport only reached 25 degrees today. That breaks the previous record low maximum for the date of 27 degrees set in 1933. Here in Thornton we were just a touch “warmer” with a high of 26 degrees.

This follows on a record low temperature that was set this morning. Additionally, there is a good chance we will break the record low temperature tomorrow morning for April 14th as well.

Severe Weather 101 – Watches, Warnings and More

Monday, April 13th, 2020 6:15am MDT
Last year's Windsor tornado highlighted just how dangerous weather in Colorado can be. Are you and your family prepared? Do you know what the watches and warnings all mean?

The 2008 Windsor tornado highlighted just how dangerous weather in Colorado can be. Are you and your family prepared? Do you know what the watches and warnings all mean?

We’ve all seen TV or Internet news of a weather related watch or warning being issued. But, how many really know what they mean? There is a pretty big difference between the two and it is important to be aware just what it means to you so you can take the appropriate precautions.

Dozens of weather related fatalities occur every year in Colorado, many simply out of ignorance. Taking the time to be aware of the conditions around you and taking appropriate action will keep you from becoming a statistic.

Naturally you can get information on current advisories from television as local stations usually do a good job of “crawling” them on the screen when they are issued. This works well if you have a TV available but if not, the radio would be a secondary source. The Internet and the National Weather Service’s website are a great one when at a computer.

The problem with relying on news media or the Internet is that their ability to warn you of a developing weather situation is dependent on your monitoring them.  Severe weather can strike without little warning.  How will you know if severe weather is about to strike if you don’t have the TV or radio on?

Your first line of defense – NOAA All Hazards Radio

NOAA Weather RadioFor just about anywhere, a special radio that picks up the NOAA’s All Hazard Radio broadcasts is the way to go and provides information from the source. Oftentimes simply called a weather radio, we highly recommend every household have one of these.

These radios are relatively inexpensive and allow you to be immediately notified of official National Weather Service warnings, watches, and forecasts as well as other hazard information like earthquakes, avalanches, chemical spills, and even AMBER alerts.  In fact, with these radios, you will be notified at the exact same time the news media is made aware giving you a head start on preparing for a developing situation.

To learn more about these devices and what you should look for when buying one, click here.

A high-tech alternative – Cell phone weather apps

Many people now have smartphones that allow for downloadable apps and weather-related ones are among the most popular.

All of these applications have a number of weather related features in common.  All provide current conditions for either the location the user is in now or for saved locations and all provide some sort of radar.

Most can be configured to sound an alert when the National Weather Service issues a watch or warning.  While they are no substitue for a weather radio, these apps provide you with immediate notification no matter where you are at.

Denver sets record low temperature for April 13, more records may fall

Monday, April 13th, 2020 6:10am MDT

Record Cold Temperatures

Our spring cold and snow has claimed one record today and may very well break another before the day is over.

As measured at DIA, Denver hit a lot temperature of 15 degrees this morning. That easily breaks the previous record low temperature for the date of 17 degrees set in 1933. Here in Thornton, our low dipped to 16 degrees.

Additionally, the record low maximum for April 13th is 27 degrees, also set in 1933. It is quite possible that we will fail to get that warm and thus set another cold temperature record today.

Tomorrow’s record low is 15 degrees (1933), and with overnight temperatures tonight forecast to dip that low, there is yet another record that may fall.

Thornton’s workweek starts off with very cold temps, a bit of snow

Monday, April 13th, 2020 5:34am MDT

The wintry weather that arrived yesterday will continue today. Once again, temperatures will be well below normal and light snow can be expected throughout the day.

Cloudy skies will be the rule through the day today. High temperatures will once again top out only in the mid to upper 20s, well below the average high for the date of 61 degrees.

As for snow, look for light snow to fall all day and through much of tonight. Light accumulations of an inch or two may be seen between now and tomorrow morning.

Tonight, overnight lows will drop into the mid-teens.

Severe Weather Awareness Week in Colorado gets started

Sunday, April 12th, 2020 8:00am MDT

In 1981 a tornado ripped through Thornton and caused major damage. Last year, funnel clouds were spotted across much of the area. Image courtesy City of Thornton archives.

As is customary, Colorado Governor John Hickenlooper has declared this coming week Severe Weather Awareness Week.  This is an opportunity for the public to get reacquainted with the dangers severe weather presents in Colorado.

Tornadoes, lightning, hail, severe wind and flooding are very real hazards that Coloradans face every year during severe weather season.  It is important that you know what to do to protect you and your family.

Just eleven years ago in what was Denver’s weather story of the year, we suffered through a period of unusually severe weather including a tornado that ripped through the Southlands Mall.

Twelve years ago on May 22nd an EF3 tornado raced north through Weld and Larimer counties resulting in one fatality near Windsor and causing several injuries and destroyed or heavily damaged hundreds of homes.

And of course in 1981 Thornton was the site of the worst tornado to ever strike the Denver metro area.

Tornadoes may get all the press but other severe weather can be damaging and deadly.

Just seven years ago, late summer flooding caused millions of dollars of damage across northeastern Colorado.  It was 44 years ago that thunderstorms brought a raging torrent of water down the Big Thompson and caused one of Colorado’s worst natural disasters.  Ten years ago hail struck the Thornton area causing damage to homes and vehicles.

In conjunction with the National Weather Service’s statements on Severe Weather Awareness Week, ThorntonWeather.com will be publishing our Severe Weather 101 series.  Each day this week a weather hazard will be discussed in depth and we will outline protective measures you can take to keep yourself and your family safe.  Please be sure to check back every day to read these important message.

Thornton’s weekend starts off mild, will end with cold and snow

Friday, April 10th, 2020 4:55am MDT

Two seasons in one weekend for us. We start out mild and pleasant but the three day period ends with much colder temperatures and accumulating snow.

For Friday, mostly sunny skies will be above for the majority of the day. High temperatures will reach the low 70s. Late afternoon brings us just a slight chance for a passing rain shower. Tonight, skies will be clearing with overnight lows around 40.

Saturday starts out nice but cloud cover will be increasing as a cold front gets closer. Highs will reach the upper 60s. By evening, we will see some light rain showers develop and continue after dark.

Overnight Saturday night into Sunday morning, temperatures are going to be dropping and rain will change over to snow. Lows will drop to around 20 degrees.

Sunday brings a return of wintry weather with light snow expected, mainly before noon but some activity lasting into Sunday night. Total accumulations of 1 to 3 inches will be possible. Daytime highs on Sunday will likely not even reach the freezing mark.

Enjoy the warm before the storm and keep an eye on our Winter Weather Briefing Page for the latest.

April 5 to April 11: This week in Denver weather history

Wednesday, April 8th, 2020 5:49am MDT

This Week in Denver Weather History

An incredibly busy week on the Denver weather history calendar as we see below.  Thunderstorms, blizzards, tornadoes, hurricane force winds and more have all been seen during this week in Denver weather history.

From the National Weather Service:

2-5

In 1918…snowfall totaled 12.4 inches over downtown Denver. Most of the snow fell on the 3rd and 4th. Temperatures were in the 20`s and 30`s. Northwest winds were sustained to 24 mph on the 2nd.

3-6

In 1898…snowfall totaled 8.7 inches in downtown Denver over the 4 days. Northeast winds were sustained to 48 mph with gusts as high as 60 mph on the 3rd.

In 1983…a prolonged heavy snow storm blanketed the area along with very cold temperatures. The greatest amounts of snow fell in the foothills where 24 to 42 inches were measured. A foot of snow fell in Boulder. Snow fell for 50 consecutive hours at Stapleton International Airport on the 3rd through the 5th with a total snowfall of 8.8 inches and a maximum accumulation on the ground of 6 inches on the 5th. In Denver…the mercury failed to rise above freezing for 3 consecutive days…on the 4th…5th… And 6th…for the first time ever in April. Five daily temperature records were set from the 4th through the 6th. Record low temperatures of 12 degrees occurred on the 5th with 7 degrees on the 6th.

The haze was the result of a huge wind storm that kicked up dust and sand from the Gobi desert in Mongolia and China during the latter half of March. Westerly winds aloft transported the dust cloud across the Pacific Ocean and over the western united states…depositing some of it on Colorado.

In 2009…a blizzard developed over the northeast plains of Colorado. Most of the urban corridor was spared from the blizzard…with the exception of eastern Adams and eastern Arapahoe counties.

Cross-winds blew several empty semI-trailers on their sides along I-70 and I-76 east of Denver. Peak north wind gusts included: 60 mph near Bennett and Keenesburg…59 mph near Brighton… And 53 mph at Denver International Airport. Over the Palmer Divide south of Denver…the high winds combined with heavy snow to produce blizzard conditions. Snowfall accumulations ranged from 3 to 8 inches over eastern Douglas and western Elbert counties. Snowfall totals included: 8 inches at Sedalia…4 inches near Castle Rock… And 3.5 inches near Franktown.

5-6

In 1939…3.0 inches of snow fell in downtown Denver. North winds were sustained to 34 mph on the 5th and to 26 mph on the 6th. The strong winds caused considerable drifting of snow. Several highways leading into the city were closed during the height of the storm due to poor visibility. Streets and highways became coated with ice in places.

In 1957…heavy snowfall totaled 6.6 inches at Stapleton Airport where north winds gusted to 46 mph. This was the second heavy snow event in less than 4 days.

In 1969…winds gusting as high as 50 to 60 mph caused only light damage along the eastern foothills. The strong winds contributed to the spread of a forest fire near Boulder. Sustained winds of 25 mph with gusts to 53 mph were recorded in Boulder. Southwest winds gusted to 38 mph on the 6th and 44 mph on the 7th at Stapleton International Airport.

In 1980…high winds howled along the foothills each day. A wind gust to 72 mph was recorded in Lakewood. The strong winds blew a camper top off a pickup truck in Denver. At Stapleton International Airport…west winds gusted to 41 mph on both days.

Thursday to offer up one more day of unseasonably warm weather

Wednesday, April 8th, 2020 4:57am MDT

Thornton is set to enjoy another pleasant, spring day today with mercury readings above normal and lots of sun. Tomorrow we enter a cooler and somewhat unsettled period that includes the potential of snow for the weekend.

Today starts off with sunny skies and we will see more of the same throughout the day with nary a cloud in sight. High temperatures will top out right near the 70 degree mark, about 10 degrees above normal.

Tonight, mostly clear skies will be above with lows dipping to the mid-30s.

For the extended period, a series of disturbances will be mixing things up. Temperatures will be closer to normal for the next few days with some chances for rain. The first part of next week is going to see things turn colder and bring chances for snow. See the extended weather forecast here for more.
