March 2014 weather recap: Month saw near normal temperatures and precip, below normal snowfall.

Looking back at the month of March we see a period of relatively uneventful weather in the Denver area.  Temperatures were near normal as was the amount of liquid precipitation, this despite the fact we saw well below normal snowfall.

The month started very cold with the first two days failing to record readings above freezing and some light snowfall.  That did not last long however and four mild days followed.  A weak system then moved in with a couple more shots of snow over a three day period.

Entering the second week of the month temperatures moderated and we saw some of our warmest readings of the month.  Light snow on the 12th fell but did not cool things down too much.

Two more very light snowfalls occurred in the last 10 days of the month while temperatures overall remained at or above normal.

Thornton’s average temperature for the month came in at 41.1 degrees, 0.7 degrees above the Denver average for March of 40.4 degrees.  Out at Denver International Airport, the Mile High City saw an average monthly temperature of 40.9 degrees.

Our warmest temperature for the month occurred on the 9th when the mercury climbed to 75.0 degrees.  The coldest reading of 3.8 degrees happened on March 2.  Denver’s warmest and coldest temperatures were on the same days with readings of 73 degrees and 4 degrees.

Two days, the first and the second, saw high temperatures below freezing.  Low temperatures below freezing occurred on 22 of the 31 days.  Denver saw similar readings.

In terms of liquid precipitation, Thornton recorded 1.06 inches.  This was a bit above Denver’s March average of 0.92 inches.  Denver was drier than normal recording 0.83 inches.

The near normal precipitation came despite the fact we saw much less snow than normal.  March is typically our snowiest with an average of 10.7 inches of the white stuff.  Thornton saw a mere 6.5 inches and Denver 6.0 inches.

Thornton’s April weather preview: Just about anything possible

Thornton's April weather previewApril 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.

March along the Colorado Front Range can be a very pleasant time as temperatures climb with the approach to and arrival of spring.  However the month is also Denver’s snowiest and wintry weather is not unusual.  This variety of conditions will be reflected in our March 2014 slideshow below.

  • Slideshow updated March 31, 2014

Showcasing images captured by ThorntonWeather.com readers as well as some of our own, our monthly slideshow covers the entire gamut of weather-related imagery.  Sunsets, sunrises, wildlife and of course snow are vividly depicted.

Throughout the month we will gather the images sent to us via email or shared with us via our various social media outlets and post them in the slideshow below.

Before and after: NASA satellite imagery shows effects of Washington state landslide

As many as two dozen people were killed on Saturday, March 22, 2014 when a massive landslide swept down a rain-soaked hill near Oso, Washington. NASA satellite imagery taken before and after the event shows the extent of the event.

Using the ‘sliders’ on the image below you can compare how the area looks normally (left) versus how it looked after the landslide (right).

From NASA:

On March 22, 2014, a rainfall-triggered landslide near Oso, Washington sent muddy debris spilling across the North Fork of the Stillaguamish River. The debris engulfed numerous homes, resulting in the deaths of at least 14 people. As of March 25, authorities reported that 176 people were still missing.

The slide left an earthen dam that blocked the river, causing a barrier lake to form. The Operational Land Imager (OLI) on Landsat 8 acquired this image of landslide debris and the barrier lake on March 23, 2014. An image of the same area acquired on January 18, 2014, is shown for comparison.

As water backed up, it raised fears of a potential flash flood. On March 23, water began to flow around the north side of the dam. However, as of the afternoon of March 25, a flash flooding watch issued by the National Weather Service remained in effect for parts of Snohomish county.

According to Durham University geologist Dave Petley, the landslide was a reactivation of an earlier landslide that caused problems in 1988 and 2006.

Video: Dust devil strikes during controlled burn at Rocky Mountain Arsenal

A prescribed burn at the Rocky Mountain Arsenal quickly got out of control when swirling winds struck.Performing prescribed burns is an important way to clear brush and renew wildland and are often done without any excitement. Mother Nature had other plans last week however as whirling winds propelled a fire beyond its containment lines at the Rocky Mountain Arsenal National Wildlife Refuge.

The amazing video of the event on March 14 was taken by a firefighter from South Metro Fire and showcases how quickly weather conditions can change and how even when well-planned, fires can quickly get out of control.

The fire is seen burning through the grasslands of the refuge when swirling wind develops – a common phenomenon caused by the heat quickly rising from the fire. Soon the fire begins to rage and tumbleweeds and burning debris are sent flying in a circular path.

Thomas Rogers, the man behind the camera, said on YouTube the fire burned an additional acre as crews backed off to gain the upper hand.

Refuge Manager David Lucas said on Facebook, “What we saw and how we reacted is exactly what we want out of our fire crews — well planned with plenty of on-site resources to manage contingencies, safety first, and well trained folks who got after it quickly.”

Enjoy the Equinox!

Every year, there are two equinoxes. One is in March; the other is in September. In 2014, the March equinox falls on March 20, 2014. On the equinoxes, the sun shines directly on the equator and the length of day and night is nearly equal. Seasons are opposite on either side of the equator, so the March equinox is called the spring (or vernal) equinox in the northern hemisphere. But in the southern hemisphere, it’s known as the fall (autumnal) equinox. What do equinoxes look like from space? The Spinning Enhanced Visible and Infrared Imager (SEVIRI) on EUMETSAT’s Meteosat-9 captured these four views of Earth from geosynchronous orbit. The images show how sunlight fell on the Earth on December 21, 2010 (upper left), and March 20 (upper right), June 21 (lower left), and September 20, 2011 (lower right). Each image was taken at 6:12 a.m. local time. Notice how on March 20 and September 20, the terminator — the divide between day and night — is a straight north-south line, and the Sun is said to sit directly above the equator. Equinox means “equal night” in Latin, capturing the idea that daytime and nighttime are equal lengths everywhere on the planet.

Announcing Tony’s Takes Photography

I have always been a shutterbug ever since my parents gave me my first SLR one Christmas when I was in high school.  It wasn’t until recent years however that I began to hone the craft and now I have launched Tony’s Takes Photography.

Certainly I have no illusion of becoming a professional photographer or having the skills of one.  This is purely a hobby for me.  However I think I do a pretty passable job and decided I would like to share my images.  Up until now that has been confined to this website and on social media with friends and family.

Over at Tony’s Takes (www.tonystakes.com) I will be sharing the images I capture.  These will usually be focused on the subjects which interest me most – extreme weather, landscapes and wildlife.  Certainly some of these photos will make their way here as always but that will be the primary spot where I post them.

Don’t worry though.  Weather is still a passion of mine andThorntonWeather.com will be staying around as always and remaining your one and only spot for truly local Thornton weather news and information!

You can find Tony’s Takes Photography at any of the links below and I would truly appreciate you spreading on the work:

Video: Los Angeles news anchors scramble under desk during earthquake

Location map of the epicenter of the magnitude 4.4 St. Patrick's Day earthquake in Los Angeles.A magnitude 4.4 earthquake struck the Los Angeles area Monday morning in the pre-dawn hours. While a relatively minor quake, it was strong enough to rattling residents and send morning TV news anchors under their desks.

According to the US Geological Survey (USGS) the quake was centered 6 miles west of Beverly Hills and at a depth of 5.3 miles. Occurring at 6:25 a.m. local time, a light aftershock of magnitude 2.7 was recorded at 7:23 a.m.

Residents stretching from Mission Viejo to the south and Oxnard to the north reported feeling the initial temblor. Beyond waking residents that were still sleeping and grabbing the attention of those already awake, initial reports indicate no significant damage.

Television stations were in the middle of their morning broadcasts when the quake hit.

KTLA news anchors Chris Schauble and Megan Henderson reacted quickly announcing that they were feeling the quake. The two acted appropriately and dived under their anchor desks for the short duration of the quake.

Video from the station shows the overhead lights shaking and Henderson noting that dust or ceiling material was falling down.
