Winter in Colorado brings some of the best ski conditions in the world but in areas outside ski area boundaries, avalanches are a very real danger. One group of skiers was lucky enough to survive an encounter with a collapsing wall of snow Sunday and captured the event on video.
Brothers Edwin and Davis LaMair were skiing near Vail Sunday in two separate groups. With a helmet mounted webcam running, Davis watched in horror as an avalanche on a nearby slope engulfed his brother.
“Holy sh**! That’s Edwin in an avalanche,” Davis exclaimed to his friends.

The map on our Northeastern Colorado River Heights and Flood Status page was not working due to changes in the feed from the Advanced Hydrologic Prediction Service. The page has now been updated and incorporates an interactive map. It also displays river heights and flood status for locations across northeastern Colorado. You can find the page in the Almanac menu at the left.

We noticed our Record Weather Event page that is fed from data from the National Weather Service was not working properly. This was due to some changes by the NWS. We have fixed this now and you can always check to see what recent record-breaking weather we have experienced by selecting the Denver / Boulder office from the drop down on the page. The page itself is under the Almanac / National Weather Service menu on the left.

Some much-needed behind the scenes work. The computer that powers all of our weather equipment – the station software, radar, lightning detector, website, etc – was on its last leg. It served us well for 5 years and it was time to go. This weekend we replaced the computer with a brand new one with far more computing power. The upgrade will allow us to continue to bring you the best local weather information and news in Thornton.

Due to changes in the way the U.S. Geological Survey formats its data, we updated our earthquake pages. The new pages now use a Google map to display recent temblors. We also have two earthquake pages now: One for quakes within a 500 mile radius of Denver, and one for all earthquakes globally. You can find the pages in the Almanac menu on the left.
7/14/13
Changes to our Live Weather Gauges page. Gauges are a bit bigger and easier to read, we added a wind rose, the scrolling text display now shows the forecast and at the bottom you can select different units of measure.
6/27/13
We changed our west facing webcam orientation pointing it a bit more vertical. This will allow a better view of the skies above while still maintaining perspective of nearby trees.
9/2/12
We’ve updated our monthly tables for Denver’s “Normals, Means & Extremes” and “”Top 10″ Precipitation & Temp”. You can find them under the Almanac menu on the left then go to Climatology & Records. You can also click here.
Some time ago we added a WeatherNation TV page that allows you to view broadcasts from the network live on our site. Now we have added a National & International Video News page with the latest from NDN’s providers including CBS, AP and many more. It is available under Area Information to the left and then select Video News.

The National Weather Service changed their forecast pages and that necessitated changes of our page as well. While the basics are the same, we took the opportunity to do a bit of an upgrade. The page will automatically display the forecast for Thornton as always but now there is a dropdown menu that allows you to easily grab the forecast from more than a dozen other cities across Colorado. Click here to check it out or select ‘NWS 5 day forecast’ from the Forecasts menu on the left.

We already have a number of ways to view current weather conditions locally and from across the globe – see the Live Conditions menu at the left. One new page we added expands on that and provides conditions from Denver area METAR stations. METARs are permanent weather stations, oftentimes located at airports, that report current conditions in a standardized format (click here for details). Our METAR page reads data from locations like Denver International Airport, Rocky Mountain Metropolitan Airport, Buckley Air Force Base and a number of other locations and provides their reported weather conditions in an easy to view format. You can access it from the Live Conditions menu on the left or by clicking here.

Our Lightning Detection Center pages are among our most popular during severe weather season. We have just added a new page that uses StormVue NGX to display lightning activity. Using Flash, the display gives you the ability to zoom in and out, set alarms, choose what type of strikes to display and much more. You can check it out here or find it in the Lightning menu to the left.

For anyone that reads our news section or views or Facebook page, you are well aware of our fondness for satellite imagery. The ‘eyes in the sky’ can provide an amazing view of weather and disasters. We have added two new pages that allow you to view some of the most amazing imagery:
The NOAA Environmental Visualization Laboratory Image of the Day provides images on a wide variety of topics from weather to climate. We have a new page that allows you to easily view the IOTD. You can find it here or in the Almanac menu to the left.
NASA satellites and spacecraft of course take amazing imagery as well, many of which are curated by the Earth Observatory. We now feature the Natural Hazards and EO Image of the Day on a special page. You can find it here or in the Almanac menu to the left.
Santa Claus begins his whirlwind trip around the globe tonight to deliver toys to all the good little boys and girls! For more than 50 years the North American Aerospace Defense Command (NORAD) has tracked Kris Kringle on Christmas Eve and helped to ensure he completes his journey safely.
ThorntonWeather.com is pleased to be able to provide live Santa tracking from NORAD right here on our site!
For many, the holiday season isn’t complete without a chill in the air and snow on the ground. Here in Denver we historically enjoy a better chance of experiencing the proverbial white Christmas than many places in the nation.
However, how the Mile High City fares in experiencing a white Christmas does depend on your definition of one.
If it means having actual snowfall on Christmas Day the chances aren’t that good. But, if simply having snow on the ground suffices, the chances improve considerably.
Earth is seen by humans in lunar orbit for the first time during Apollo 8. (NASA)
It was Christmas Eve in 1968 when three brave astronauts, the first humans to leave Earth orbit, circled the moon. As the 45th anniversary of that event approaches, NASA has released a video that recreates the iconic Earthrise image that has captivated the world since.
Using imagery obtained from its Lunar Reconnaissance Orbiter, the video released by NASA yesterday allows viewers to see Earthrise as it was first witnessed 45 years ago.
Audio from the Apollo 8 mission provides commentary from the astronauts as they conducted routine observations – until the spacecraft oriented itself to allow them view the planet. The astronauts then scramble to get cameras in place to capture the event.
Colorado’s famously inconsistent weather appears to be on full display this month. Just two weeks ago we were setting records for cold. Today we broke a record high temperature and tied the record high minimum.
At 12:59 p.m. the temperature at Denver International Airport reached 68 degrees. This broke the old record high temperature for December 18 of 66 degrees last set in 1979.
Additionally, Denver’s low temperature was 40 degrees. This tied the record low maximum for the date set in 1917.
The average high for December 18 is 42 degrees and the average low is 17 degrees.
Here in Thornton we were just slightly cooler as the mercury here topped out at 67 degrees at 12:44 p.m. Our low dropped to 39 degrees.

A powerful winter storm system struck parts of the Middle East on Friday to the delight of some residents but causing havoc in other locations where snow is a rarity.
In Cairo, Egypt snow fell, reportedly for the first time in 112 years, covering parts of the city in a light blanket of white.
Parts of Israel saw heavy snow totaling up to three feet. Jerusalem Mayor Nir Barkat told The Times of Israel, “We’re facing a rare storm the likes of which we’ve never seen.”
The local meteorological agency said it was the worst snowstorm seen since at least 1953.

Last month a tornado outbreak visited death and destruction across multiple states in the nation’s midsection. Security camera footage just release by a homeowner in Illinois whose house was destroyed captures the destruction as it happens.
Over 100 tornadoes spanning seven states were reported on November 17. While the actual number of twisters was likely lower due to duplicates, it was an extraordinary tornado outbreak, particularly given how late in the year it occurred.
The tornado that struck Washington, IL on that fateful day has been determined to be an EF-4 on the Enhanced Fujita Scale.
This week a YouTube user by the name of ‘athlon770’ released security camera footage of the event.
From four different cameras , the video shows exterior views as the tornado approaches and the wind starts throwing debris. In the climax, the inside of the home virtually explodes as it takes a direct strike from the twister.
Following the video, the user adds still photos of the aftermath. It is truly a devastating scene.
In a video from Greenpeace, global warming has taken its toll on Santa Claus and the North Pole.
Global warming has prompted Santa Claus to issue an urgent appeal to children to help save his home in the Arctic. In a new video from the radical environmental group Greenpeace, the jolly old elf hardly looks like himself as he announces, “I bring bad tidings.”
With labored breaths, Santa says, “For some time now melting ice, here, at the North Pole has made our operations and our day to day life intolerable and impossible and there may be no alternative but to cancel Christmas.”
The timing of Greenpeace’s video is arguably not the best.
The Arctic sea ice minimum, reached in September, saw a 49% increase over the previous year. That represents an increase of 653,000 square miles giving Santa and the reindeer quite a bit more snow and ice to play on and use to prepare for Christmas.
Thornton, Colorado temperatures during the December 2013 cold spell.
Thornton’s December 2013 Arctic blast has come to an end as the mercury finally climbed above freezing today. For nearly seven straight days we saw temperatures below 32 degrees.
Soon after noon on Tuesday, December 3 the cold front arrived along the Colorado Front Range. The mercury would plummet quickly from a high that day of 55.9 degrees and drop below freezing at 1:56 p.m.
It wasn’t until 9:12 a.m. this morning when the temperature finally climbed above 32 degrees, the rising temperatures being pushed higher by Chinook winds. In all, sub-freezing temperatures were recorded for 6 days, 19 hours and 16 minutes straight.
Looking at how the event ranks in comparison to historical Denver cold spells, it falls short of making the list of top 10 longest periods with maximum temperatures below freezing.
Number 10 on the list is a nine day streak that ended on December 25, 1983. The top spot goes to a 14 day period that ended on November 29, 1880.
Snowfall was relatively minimal however as is often the case when temperatures drop so far. Thornton measured 2.4 inches and Denver 3.1 inches.
The table below shows the high and low temperatures for Thornton and Denver during the cold spell.
