Colorado’s famously highly variable weather seems to showcase itself during the month of May when a variety of weather conditions can be seen.
Winter-like temperatures and snow are possible as are mid-summer like temperatures or the more typical spring severe weather.
As the month starts out in 2022 we are going to enjoy some much-needed precipitation. Long range forecasts however portend a potentially drier than normal month.
The month can certainly bring extremes. Snow is not entirely uncommon during the month, oftentimes causing damage to newly bloomed trees. More common however is severe weather, particularly in the latter half of the month. Thunderstorms become more frequent and their associated hazards – lightning, wind, hail and tornadoes – are usual visitors.
April can be a tricky month weather-wise with everything from mild temperatures to snow to severe weather being possible. The good thing about that is that it provides plenty of chances for great photos!
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!
Throw in our usual wildlife plus the wide variety of birds that return to the Centennial State for the spring and summer and there is a lot going on.

What is missing in the slideshow above? Your photo!
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.
To share you images with us and get them included in the slideshow just email them to us or share them with ThorntonWeather.com on any of the various social media outlets. Links are provided below.
We knew it was going to be extraordinarily warm and blustery today, particularly for April. The numbers bear it out as Denver set a record high temperature for the date, one that also tied for the second warmest April reading on record.
As measured at Denver International Airport, the Mile High City topped out at 89 degrees. That bests the previous record high for April 22nd of 88 degrees set in 1989. The reading was also the second warmest April temperature recorded in Denver history coming in second to a 90 degree reading on April 30, 1992.
Here in Thornton we were just a hair cooler with a high of 88 degrees.

Of all the weather types associated with thunderstorms – hail, tornadoes, floods, etc – lightning is usually the most dangerous. In the United States there are an estimated 25 million cloud to ground lightning flashes each year and each one is a potential threat to life and property.
During the past 10 years there has been an annual average of 39 lightning fatalities in the United States. Last year, 23 people lost their lives due to lightning.
Colorado is ranked # 2 in lightning related deaths (2001 – 2010) so the danger this presents to life and property is very significant for us. It is interesting to note though that Colorado ranks only 32nd in the number of cloud to ground strikes over that same period. Which means, in short, we have fewer strikes than many other states and yet more deaths.
This highlights the fact that, quite frankly, folks here in Colorado are not aware of the dangers lightning presents and they do not take proper steps to protect themselves. One of the great things about Colorado are the outdoor activities we all enjoy, but there comes a time when we need to head indoors.

During the spring and summer months in Colorado, a wide array of severe weather can strike. Tornadoes may grab all the headlines, but straight line winds and hail can do a great amount of damage in their own right – and they are more common.
Straight line winds are winds out of a thunderstorm and are classified as severe when they hit 58 mph. These winds can reach tornado and hurricane force and as a result, cause property damage and can injure and even kill animals and humans.
These winds are usually the result of air cooling rapidly due to precipitation or evaporation. As the cooler air is heavier than the surrounding warmer air, it rushes downward, accelerating toward the ground and spreads out as it hits, much like pancake batter being poured onto a griddle.
There was definitely a chill in the air this morning and the data shows it was record-setting.
As measured at Denver International Airport, the official low for the Mile High City hit 10 degrees this morning. This easily bests the previous record low for the date of 15 degrees set just two years ago in 2020.
Here in Thornton, we weren’t quite as cold with a low of 13 degrees.
We will warm up some today but temperatures will remain well below normal and we will again be dealing with blustery winds.
The 2008 Windsor Tornado highlights the very real danger twisters present in Colorado. Do you know when to do when one strikes?
One fact that may surprise those new to Colorado is that we are actually on the western edge of the infamous Tornado Alley. This large swath of land comprises much of the nation’s midsection and is a unique place as the United States sees more tornadoes than any other place on earth. In fact, tornadoes have been recorded in all 50 states including Alaska and Hawaii.
Closer to home, Colorado sees our share of these storms. In fact, one metro area county – Weld County – holds the distinction of being the “tornado capital of the world.” With 252 tornados from 1950-2011, no single county in the nation has had more tornadoes! Adams County is number two in the state and isn’t far behind with 156 over that same period. Granted these numbers are skewed a bit simply due to the sheer size of those counties, but it does serve to highlight the real danger that tornadoes present.
One common myth is that tornadoes don’t strike metropolitan areas. This has been disproved many times including here in Colorado in 1981 when an F2 tornado struck Thornton. Image courtesy the City of Thornton archives.
The most well known tornado outbreak in the metro area occurred on June 15, 1988. Five tornadoes resulted in seven injuries and damage in excess of $15 million.
The greatest threat for tornadoes occurs during late spring and early summer when you have a combination of heat and moisture in the lower atmosphere. Here in Colorado, tornadoes are frequent from May through August with June being the most active month.
Colorado ranks 10th in terms of the number of tornadoes with 1,911 events from 1950-2011. One good thing is that our high altitude and drier air do make it harder for the monster supercells that spawn the biggest tornadoes to form. Most of our tornadoes are small and short lived. Further, thanks to the wide open spaces of the eastern half of our state, many strike sparsely populated areas. This is reflected in the fact that we rank 38th for tornado related deaths.
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
For 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.
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.
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.

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.
