Upgraded – National Weather Service issues Winter Storm Warning as storm approaches

A Winter Storm Warning will go into effect Thursday morning.  Thornton may see 5 to 10 inches of snow out of the system.
A Winter Storm Warning will go into effect Thursday morning. Thornton may see 5 to 10 inches of snow out of the system.

The National Weather Service has upgraded what was a Winter Storm Watch to a warning and is now forecasting 5 to 10 inches of snow.  Everything seems to be aligning for Thornton and the rest of the Denver metro area to see its first winter storm of the season.

Most of the computers models are coming together with a solution that will pass a low pressure system across southern Colorado.  This solution sets things up for a significant winter weather event with accumulating snow across most of northeastern Colorado.

The Winter Storm Warning will go into effect at 9:00am Thursday and run through 6:00am Friday and is for snow and blowing snow.  Snow will gradually start Thursday morning in the pre-dawn hours and then increase in intensity before noon.  Throughout the day and into early morning Friday the snow will continue. 

Accumulations from 5 to 10 inches are possible with some isolated areas receiving more.  The snow will be joined with gusty winds to 35 mph and bitter Arctic cold temperatures that will send wind chill temperatures plumetting. 

Tomorrow morning’s commute may be a bit messy depending on the timing of the start of the snow.  The afternoon rush hour may be a doozy.  The one possible consolation will be that the snow is likely to of the relatively dry type that we see this year so shoveling shouldn’t be too bad. 

The cold that is accompanying this storm is the other notable aspect.  Thursday will see a high temperature around 23 degrees – nearly 30 degrees cooler than today.  Further that high temperature will be achieved around midnight.  After that the mercury will fall to around 16 degrees by 6:00pm with wind chills into the single digits.

Overnight lows Thursday night will be near zero.  Friday sees little in the way of improvement in terms of temperature with a forecast high of only 15 degrees.  As the clouds clear out late Friday that will allow for even colder nighttime temperatures Friday night with the mercury likely dipping to below zero.

As this storm hits conditions will likely become hazardous for travel and residents should be prepared.  For more information on what you can do to get ready and protect your family, be sure to check out the links below for our series on Winter Weather Preparedness.

From the southern United States to the mid-Atlantic and New England a major winter storm has had a wide impact in recent days.  Some areas of the south recorded their first Christmas snow in decades and as the storm moved further northeast it turned into a major blizzard.

Snow fell as far south as Jacksonville, Florida over the holiday and areas further north recorded moderate snowfall.  Huntsville, Alabama saw 6 inches of snow; Raleigh, North Carolina saw 8.5 inches and Gatlinburg, Tennessee recorded 8.0 inches.

Those totals are minimal however to what is being deposited on a large area from New York City to Boston.  Central Park has reported 13 inches and Brooklyn 17.5 inches.  In New Jersey Atlantic City reported 19.0 inches while Foxboro, Massachusetts has seen 11.5 inches.

Travel across the northeastern U.S. came to a standstill as travel by road, rail and air was impacted.  Thousands of flights into and out of the area were canceled as airports in New York and New Jersey shuttered.  Airlines at Denver International Airport were impacted by the storm and its ripple effect.

The nor’easter was imaged this afternoon by NOAA satellites that provided a birds-eye view of the area before and after the storm. 

A furor erupted when the National Football League announced it would postpone the game between the Philadelphia Eagles and Minnesota Vikings and move it to Tuesday.  The league cited concerns for fan safety however many were quick to point out that it is highly unusual for the NFL to postpone a game based on snow of any amount. 

Pennsylvania Governor Ed Rendell told FOX, “It’s an absolute joke. We’re becoming a nation of wussies.”

December 26 to January 1 - This week in Denver weather history

Winter wind in Colorado can be quite nasty oftentimes reaching damaging levels and we see numerous occurrences of that in our look back at this week in Denver weather history.  Also notable are storm system just a few years ago in 2006 and 2007 that dumped a good amount of snow on the Denver area.

25-26

In 1904…after a warm Christmas Day with a high temperature of 50 degrees…a late day cold front plunged temperatures to a low of 7 degrees…produced northeast winds sustained to 40 mph with gusts to 54 mph…and produced 5.2 inches of snow overnight for a late white Christmas.  The maximum temperature on the 26th was only 16 degrees.

25-31

In 1980…temperatures were unusually warm during the week between Christmas and New Year’s.  High temperatures for the week ranged from the mid-50’s to the mid-70’s.  Four temperature records were set.  Record highs occurred on the 26th with 68 degrees…the 27th with 75 degrees…and the 30th with 71 degrees.  A record high minimum temperature of 41 degrees occurred on the 27th.

26 

In 1877…heavy snow fell during the early morning and totaled nearly 6 inches.  Precipitation from melted snow was 0.58 inch.  After the snowfall…a number of sleighs were seen on the city streets.
 
In 1879…after a morning low of 4 degrees below zero… The temperature climbed to a high of 57 degrees in the city.
 
In 1907…west winds were sustained to 40 mph.  The Chinook winds warmed the temperature to a high of 62 degrees.
 
In 1949…west winds gusted to 50 mph at Stapleton Airport.
 
In 1998…intense…but localized…downslope high winds developed near Wondervu in the foothills southwest of Boulder.  Winds frequently gusted to 100 mph with a highest reported wind gust to 104 mph.  West winds gusted to only 43 mph at Denver International Airport.

As all the good little boys and girls rush to open their Christmas presents this morning most were asleep and missed Santa’s flight over Thornton and the Mile High City.  The good folks at NORAD in Colorado Springs however were able to capture video of St. Nick as he made his rounds.

Santa’s annual trip across the globe covers hundreds of thousands of miles.  From the North Pole to each of the seven continents and billions of presents delivered Santa Claus’ 2010 trip went off without a hitch. 

For 55 years the good men and women at the North American Aerospace Defense Command (NORAD) have tracked St. Nick on his annual journey and this year their cameras captured him as he visited Denver.  Check out the video below.  To see more pictures and videos of his trip check out our Santa Tracker page.

More than 45% of nation covered in snow while Thornton remains dry

Last year a pre-holiday snowstorm covered Thornton in a blanket of white ensuring we had a white Christmas. This year the color will be brown for the Front Range but a sizeable chunk of the United States will have snow on the ground for the holiday.

From North Dakota to Minnesota and Iowa, a major winter storm dumped nearly two feet of snow on the upper Midwest two weeks ago.  The sheer weight of the snow was enough to collapse the Metrodome in Minnesota and send the Minnesota Vikings scrambling to find someplace to play football.

A new storm in recent days has brought flooding rains to California, Nevada, Arizona and Utah while the higher elevations in those states plus western Colorado see extraordinary snowfall.  Over a five day period many areas were finding that even a yard stick isn’t tall enough to record the snow that has fallen.

Thursday brings a slight chance for some precipitation but there will little if any accumulation from it.  Those in Denver wanting a white Colorado Christmas will need to head for the hills. Some of the extraordinary snowfall totals recorded over the last few days include:

GOTHIC                               82.0
CRESTED BUTTE 6.2 N                  77.5
COAL BANK PASS                       48.0
RED MOUNTAIN PASS                    44.5
MOLAS PASS                           41.0
SILVERTHRONE 10 E                    32.0

Denver’s white Christmas history – Not as common as one might think

Don't bet on a white Christmas in Thornton - the historical odds aren't very good.
Don't bet on a white Christmas in Thornton - the historical odds aren't very good.

As Christmas gets closer everyone always wonders if we are going to get the proverbial white Christmas. Unfortunately, if you look at Denver and Thornton weather history, the chances arent all that good but it also depends on what you define as a white Christmas.

December just isnt that snowy of a month, ranking as only the fourth snowiest (behind March, November and April) so historically we have a bit of a disadvantage.  There have however been some very white Christmases in our history and it is fun to look back.

Clear skies over Thornton provide prime lunar eclipse viewing

Late yesterday afternoon the weather didn’t look like it would cooperate and allow viewing of the rare winter solstice lunar eclipse but in the end Mother Nature was generous.  Some thin, high clouds cast a bit of a ‘fog’ over the start of the event but those cleared and the view was extraordinary.

According to Geoff Chester of the US Naval Observatory, the last time a total lunar eclipse coincided with the winter solstice was on December 21, 1638.  That is the only other time since the birth of Christ that the conjunction of the two events occurred.  For those that live long enough, it won’t be a 372 year wait for the next one however.  Chester says December 21, 2094 affords the next chance.

From start to finish the event lasted about 3 1/2 hours with totality lasting a period of 72 minutes.  At its peak at 1:17am MST the moon was cast in a burnt orange color as the shadow of the Earth enveloped it.

Lunar eclipses unto themselves are not particularly rare events.  Two total lunar eclipses will occur in 2011, one in June and another in December.  North America sky watchers however will not be able to see the June event and only part of the December one.  The next total lunar eclipse visible in North America occurs on April 15, 2014.

December 19 to December 25 – This week in Denver weather history

December 19 to December 25 - This week in Denver weather history.

Cold and snow dominate our look at the week leading up to the Christmas holiday.  Certainly the infamous Christmas Eve Blizzard of 1982 is the one event that most long-time resident will remember as it was truly one for the history books.  Also notable was a cold front that moved through in 1988 that dropped temperatures well below zero and was responsible for at least five deaths.

17-24

In 1924…a prolonged cold spell occurred after mild temperatures during the first half of the month.  Most low temperatures dipped below zero with the coldest reading of 15 degrees below zero occurring on the 24th. The high temperature of only 5 degrees on the 18th was a record low maximum for the date.

18-24

In 1998…a vigorous cold front with north winds gusting as high as 38 mph at Denver International Airport on the 18th dropped temperatures from a high of 51 degrees to a low of just 6 degrees before midnight.  The arctic air mass that settled over metro Denver produced intermittent light snow and a week-long protracted cold spell that caused low temperatures to plunge well below zero for 6 consecutive nights.  The coldest temperature was 19 degrees below zero on the morning of the 22nd.  High temperatures climbed only into the single digits on 4 consecutive days…from the 19th through the 22nd.  At least 15 people…mostly homeless… Were treated for hypothermia at area hospitals.  The bitter cold weather was responsible…either directly or indirectly… For at least 5 fatalities.  Three of the victims died directly from exposure.  The cold weather also caused intermittent power outages.  Following the cold snap… Thawing water pipes cracked and burst in several homes and businesses…causing extensive damage.  Only one temperature record was set.  The high temperature of only 7 degrees on the 19th set a record low maximum for the date.

19

In 1913…post-frontal heavy snowfall totaled 8.5 inches over downtown Denver.  North winds were sustained to only 16 mph.
 
In 1994…an intense pacific storm system and associated cold front moved across Colorado early in the day.  Strong downslope winds buffeted the Front Range eastern foothills. The highest wind gust recorded was 92 mph at Rocky Flats in northern Jefferson County.  Most of the wind gusts during the day ranged from 63 to 86 mph with lighter gusts of 40 to 58 mph on the northeast plains.  The strong winds downed power lines and poles in south Lakewood…causing power outages to 2400 homes.  Other small power outages and surges occurred across metro Denver.  Northwest winds gusted to 43 mph at Stapleton International Airport.

“Double Rainbow Guy” video makes YouTube’s top 10 of 2010

Video of a double rainbow shot by a man living near Yosemite National Park has been named one of YouTube's top videos of the year.
Video of a double rainbow shot by a man living near Yosemite National Park has been named one of YouTube's top videos of the year.

Rainbows are certainly one of Mother Nature’s most beautiful weather-related phenomena.  One man’s excited reaction to a double rainbow became a YouTube hit earlier this year and has now been named the sixth most popular video of 2010.

Shot from near the man’s home in one of the nation’s premier parks, Yosemite, his sheer elation to the rainbow invites reactions ranging from laughter to tears from those who have watched it. 

Published on YouTube on January 8th the video has been watched more than 21 million times since and led to the “Double Rainbow Guy” making an appearance on the Jimmy Kimmel Show.

In a blog entry announcing “The Moments that Defined YouTube in 2010”, the service said the video became “one of the most beloved memes of 2010.”

The weather-related video ranked as number six on the list of top 10 most-watched YouTube videos falling behind the popular video of Greyson Chance singing Paparazzi and an Old Spice commercial.  The double rainbow video did beat out the infamous video of Justin Bieber surprising a young fan and a trailer for the latest Twilight Saga movie

We of course think that the video we shot while storm chasing in southeastern Colorado deserves an honorable mention.  😉
