At about this time of year an extraordinarily beautiful event takes place when the cherry trees that line the Tidal Basin in our nation’s capitol blossom.  For those that haven’t seen it first hand, the blossoms coupled with the sights and monuments is incredible.

The entire blossom event lasts for a relatively short two week period during which bright pink blossoms cover the trees.  Wednesday, the trees reached their peak bloom period for this year and this coming weekend the event will be highlighted with the annual parade and street festival – all part of the National Cherry Blossom Festival

The history of how the cherry trees came to the capitol goes back nearly 100 years.  According to the National Park Service

The plantings of cherry trees originated in 1912 as a gift of friendship to the People of the United States from the People of Japan. In Japan, the flowering cherry tree, or “Sakura,” is an exalted flowering plant. The beauty of the cherry blossom is a potent symbol equated with the evanescence of human life and epitomizes the transformation of Japanese culture throughout the ages.

As we wait for our own trees to blossom here in Colorado, take a look at this incredible slideshow of images taken just the other day of Washington D.C.’s trees.  Thank you to Jim Schuyler for sharing the photos as well as to Justin Berk, the Baltimore Weather Examiner for passing them on to us.

From the Las Vegas Strip to the Great Pyramids, lights were turned off across the globe for one hour on Saturday as part of Earth Hour, an event to draw attention to climate change.  Sponsored by the World Wildlife Fund (WWF), nearly 4,000 cities and towns in 88 countries dimmed nonessential lighting in what U.N. Secretary-General Ban Ki-moon hoped would, “be largest demonstration of public concern about climate change ever attempted.”

At 8:30pm local time, cities including Berlin, Beijing, Copenhagen, Dubai, Hong Kong, London, Mexico City, Moscow, Paris, Sydney and Toronto dimmed downtown lights and lighting at landmarks.  Here in the United States Albuquerque, Boston, Chicago, Dallas, Las Vegas, Los Angeles, New York, Washington D.C. and many others including Denver and Boulder participated.

In the nation’s capitol, the Capitol dome went dim at 8:30pm as did the Empire State Building in New York, Central Park and the George Washington Bridge.  In London, Big Ben was darkened and in Australia the iconic Sydney Opera House saw its lights extinguished. 

Other landmarks to go dim as part of the event included the Great Pyramids in Egypt, the Vatican, Niagara Falls, the Eiffel Tower, the Acropolis, the ‘Bird’s Nest’ in China and the Las Vegas Strip.  Here in Denver, lights were turned out in the Wellington Webb Building, the City and County Building, the Human Services Building on Federal Boulevard and the McNichols Building.

Acknowledging that the event will not do anything to decrease the world’s carbon footprint, the WWF likens it to other symbolic events such as the Boston Tea Party or the protests of the 1960’s.  Organizers are hopeful the event will get the attention of world leaders who will meet in Copenhagen, Denmark in December for a summit on climate change.

In an interview on CNN, WWF CEO Carter Roberts said, “We think we are going to have 100 million people around the world sending a message that climate change is real, and we need to take action now.  The world is watching to see what America is going to do because if America acts on climate change, the world will follow.”

A Preview of Denver’s April Weather – Something for Everyone

Do April showers bring May flowers? Find out in our April 2009 weather preview!

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 good news is that sunshine and warmer temperatures are usually in abundance as the normal highs during the month move up from 57 degrees on the first to 65 degrees on the 30th. It is not unusual to have a number of days well into the 70’s and the low 80’s. We also see the normal lows move above freezing from 30 degrees at the start of the month to 39 degrees by the end. Temperature extremes can hit both ends of the spectrum with a record low of 2 degrees below zero on April 2, 1975 and a record high of 90 degrees on April 30, 1992.

Denver blizzard moves out as the digging out begins

Thornton begins digging out from the March Blizzard of 2009.
Thornton begins digging out from the March Blizzard of 2009. This image is from our webcam as the storm really began in earnest just before noon.

The sun is already beginning to shine in the wake of Denver’s biggest snowstorm of the 2008 – 2009 winter season.  The storm was also Denver’s biggest since December 2007 when a series of storms dumped more than 30 inches on the city.  While the snow brings much-needed moisture to the parched Front Range, it was a stark contrast to the 70 degree temperatures of just a few days ago. 

Here is Thornton we received 11.4 inches of snow from the storm which increases our season total to 38.1 inches.  While yesterday’s snow helps, that is still barely half of what we average in a season so much more is needed if we want to make up lost ground.

Cold and wind were also part of the story.  Thornton’s high temperature yesterday was 35 degrees but that occurred before 11:00am.  Once the storm arrived, the mercury plummetted 15 degrees and we saw temperatures in the mid-teens.  Winds are what made the storm a blizzard and we had plenty of that with gusts to 33 mph.  The cold temperatures and wind coupled to give us wind chills in the low single digits and Thornton actually recorded a maximum wind chill of 1.3 degrees below zero.

Thornton’s March Blizzard 2009 – Time lapse videos

The March Blizzard of 2009 is winding down and it gives us a chance to look at all that happened in the last 36 hours or so.  One of the neat things to look at is the 24 hour time lapse video from yesterday.  Check out the video from our two webcams:

Earth Hour set to highlight climate change

On March 28th, 1,500 cities worldwide will particpate in Earth Hour to draw attention to climate change.  See the video below for details.
On March 28th, 1,500 cities worldwide will particpate in Earth Hour to draw attention to climate change. See the video below for details.

On March 28th at 8:30pm local time, cities across the globe will participate in Earth Hour by turning off their lights for one hour.  More than 1,500 cities around the globe have committed to taking the measure to highlight worries about climate change.  U.N. Secretary-General Ban Ki-moon has asked for support for the endeavor saying,”It promises to be largest demonstration of public concern about climate change ever attempted.”

Organized by the World Wildlife Fund (WWF), last year’s event saw an estimated 50 million people worldwide participate.  Organizers hope for a much more significant event this year with a goal of 1 billion as a way to ‘send a strong message to our political leaders that we want them to take meaningful action on climate change.’

Acknowledging that the event will not do anything to decrease the world’s carbon footprint, the WWF likens it to other symbolic events such as the Boston Tea Party or the protests of the 1960’s.

I urge citizens everywhere to join us.  We are on a dangerous path, the planet is warming and we must change our ways.
– U.N. Secretary-General Ban Ki-moon

Berlin, Beijing, Copenhagen, Dubai, Hong Kong, London, Mexico City, Moscow, Paris, Sydney and Toronto are some of the international cities that have committed to participate.  Here in the United States many major cities have agreed to turn their lights out including Albuquerque, Boston, Chicago, Dallas, Las Vegas, Los Angeles, New York, Washington D.C. and more.

Colorado as well has six cities participating including Boulder, Commerce City, Denver, Fort Collins, Silverthorne, and Westminster.  Denver will darken four public buildings:  the Wellington Webb Building, the City and County Building, the Human Services Building on Federal Boulevard and the McNichols Building.

Major snowstorm starts to hit Thornton, Blizzard Warning issued

A Blizzard Warning is in effect for all of eastern Colorado, including Thornton.
A Blizzard Warning is in effect for all of eastern Colorado, including Thornton.

Thornton and Denver are preparing for what will be its biggest snowstorm of the season today as the National Weather Service has now issued a Blizzard Warning for all of eastern Colorado.  The major storm we had been watching in recent days is now arriving over the Front Range and snow is starting to fall and will become widespread by 7:00am.  Initially the snow will melt as it hits the ground but as it gets heavier, it will begin to accumulate.

March is our snowiest month and this is setting up to be a classic late winter / early spring storm with lots of Pacific moisture and a Canadian cold front dipping down from the north.  Winds are now starting to come out of the east and northeast providing the required upslope conditions that will slow the storm down and hold it over the Front Range.

Between noon and about 9:00pm the snow will be at its heaviest as will the wind which will cause significant drifting and road travel will become treacherous – the afternoon rush hour is almost certainly going to be a big mess.  Road closures are likely to happen at some point later today, particularly south and east.  Areas along the Palmer Divide, the foothills and the south metro area will have the most snow with lower amounts as you move north.  The Denver metro area can look for snowfall totals between 8 and 16 inches while there could be up to two feet of snow in areas south and west.

Remember, a Blizzard Warning means that severe conditions are expected and winds can gust in excess of 35 mph coupled with significant snowfall.  Visibilities may be reduced to a quarter of a mile or less and travel will be extremely dangerous and is discouraged.  Be sure you are prepared if you do travel and should you get stranded, stay with your vehicle – do not head out and seek help!  Going through these storms is always a major task.  We ask that you please be careful if you are on the roads and if you have folks in your area that need a bit of help digging out, lend them a hand.

Since January, Denver has had 15% of its normal precipitation and for the snow season we are at a mere 41%.  While the snow will be troublesome, we are truly in need of moisture so this is a welcome sight in some respects.

Major storm continues on path, Denver could get 12+ inches of snow

A major spring storm could bring more than 12 inches of snow to Denver and Thornton.
A major spring storm could bring more than 12 inches of snow to Denver and Thornton.

The major winter storm we have been tracking for the last couple of days continues on its path toward Denver and the Front Range and before it is over, Denver could see more than a foot of snow.  The latest computer models indicate the storm is coming a bit further north than previously thought which increases the changes for what will be a very significant snow event for us. 

Snow in the mountains tonight will begin to spread to Denver and the Front Range Thursday morning and it will last through Thursday evening and beyond.  Highlighting the significance of the storm, the National Weather Service has issued a Winter Storm Warning (see below for text of warning) for all of northeastern Colorado including Denver. 

The NWS is forecasting snow totals from 8 to 15 inches for the metro area (see image below) and from 1 to 2 feet along the Palmer Divide.  I think that may be a bit optimistic myself but there is little doubt we are in for our biggest storm of the snow season.  Areas south and west like Highlands Ranch, Parker and Golden will almost certainly experience the most snow in the metro area.  See the image below for potential snow totals.
