Stormchasers capture photo and video of stunning supercell in Wyoming
Spring brings severe weather to the Great Plains and with those storms comes stormchasers. One group of chasers captured video and photos of a supercell’s amazing structure as it moved across northeastern Wyoming.
The video, taken by Basehunters, shows the motion of the swirling mass of a low precipitation supercell near Newcastle. Still imagery provides a dramatic view of the storm cell.
Check them out below.

Photos, video from 11 years ago showcase potential snow damage from coming storm
With a significant spring storm set to impact our area tonight through tomorrow, a similar storm 10 years ago today provides a reminder of the potential for damage.
From May 9 to May 10, 2003, heavy, wet snow fell on the Denver area, much of it focused over northern suburbs like Thornton. Power lines were downed and trees took a beating.
Here in Thornton we received 7 inches as did Broomfield and DIA.
The National Weather Service ‘day in history’ noted:
“In 2003…a late spring snowstorm hammered the mountains… Eastern foothills…and urban corridor. The heaviest snowfall occurred north of Interstate 70. The heavy wet snow caused damage to trees throughout metro Denver and downed power lines. About 40 thousand people along the urban corridor were without power. Storm total snowfall amounts included: 11.5 inches in Louisville… 8 inches in Boulder and Broomfield; 7 inches in Thornton…Broomfield…at Denver International Airport… And at the site of the former Stapleton International Airport; and 6 inches 4 miles east of Denver. Snowfall ranged from 4 to 9 inches across extreme southern weld County. In the foothills…15 inches of snow fell near Jamestown…9 inches at Rollinsville and Rawah…with 8 inches at Chief Hosa and atop Lookout Mountain. The snow was accompanied by thunder on the afternoon of the 9th at Denver International Airport where west winds gusted to 25 mph on the 9th and north winds gusted to 22 mph on the 10th.”
The image to the right and the photos and video were taken in the ThorntonWeather.com backyard as the storm started to come to an end.
Live updates: Thornton’s first severe weather event of the season
Springtime brings severe weather to Colorado and it is appearing very likely much of that is in store today. While the best chances will be northeast of Thornton, the potential exists for damaging winds, large hail and possibly tornadoes.
We will be monitoring monitoring the storm very closely and posting regularly to our Facebook page and Twitter feed. You can follow along in real time below. We are also on Google+ here.
For complete coverage including the latest forecasts, watches, warnings and more, please monitor our Severe Weather Briefing page.
Drive into the mountains brings stark reminders of Colorado’s September 2013 floods
We went for a drive through Estes Park and into Rocky Mountain National Park yesterday. Always beautiful but now, a bit more dramatic for other reasons.
The devastation from last year’s floods are still very visible and while much has done rebuilding, much more needs to be done. Here you can see what is left of a car after being caught in the flood on Highway 34. In the background, the collapsed hillside is seen and two construction vehicles work to rebuild the riverbank.
Piles of debris and rubble as still visible as you climb up the canyon. While some houses have been rebuilt, others remain in pieces.
Thornton’s May preview: From snow to severe storms
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 2014 we are going to enjoy a mild period with unseasonably warm temperatures and dry conditions. Long range forecasts predict a relatively ‘normal’ May.
However the month can 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.
For a complete look at what lies ahead for the month of May, check out our full preview here.
April 2014 weather recap: Warmer and drier than normal conditions
The month of April lacked much in the way of drama for northeastern Colorado. Overall temperatures were warmer than normal and precipitation and snow were lacking a bit.
April started out on the cool side and brought the first snow of the month on the 3rd. By the 8th temperatures had rebounded and we enjoyed a five-day stretch of high temps in the 70s.
A storm system and cold front cooled things down on the 13th and we saw a couple of days of light snowfall. As always the weather bounced back and Thornton recorded its first 80+ degree day of the year on the 18th.
The final four days of the month saw things turn cool again. Some light rain was seen but the bigger story was a period of unusually windy conditions.
Denver’s average April temperature is 47.4 degrees (1981 – 2010). For April 2014, the average temperature in Thornton was more than two degrees higher at 49.6 degrees. Out at Denver International Airport, the average came in a bit cooler at 49.0 degrees.
Temperatures in Thornton ranged from a high of 81.3 degrees on the 18th down to a low of 17.6 degrees on the 14th. DIA saw its warmest reading of 80 degrees on the 22nd and its coldest of 18 degrees on the 14th.
Low temperatures dropped below freezing on 11 days in Thornton. No readings below zero were recorded.
In terms of precipitation, Thornton measured 0.97 inch in the bucket. This is a good ways below the Denver April average of 1.71 inches. DIA saw more precipitation than us with a reading of 1.24 inches.
Similarly, snowfall fell short of normal in Thornton and Denver. On average the Mile High City sees 6.8 inches in April. Thornton recorded only 5.5 inches and DIA 5.6 inches.
