Top weather story of 2008 – The Windsor tornado

May 22, 2008 started like most other spring days in Colorado.  That Thursday morning had dawned with relatively mild temperatures and a touch of humidity in the air.  That moisture in the air was a warning sign as moist air from the Gulf of Mexico was entering the state and a signal of the potential for severe storms.  No one knew though just what was in store for a small town in northeastern Colorado.

As temperatures rose in the morning, the moist air near the ground mixed with fast moving dry air aloft and created conditions ideal for supercell thunderstorms and tornadoes.  Hail began to fall around 11:20am near Platteville, a harbinger of things to come.  As the weather situation became much more excited and confused, reports of a twister on the ground near Gilcrest at 11:29 rolled in.

A classic wedge tornado had formed and was moving to the north-northwest at a leisurely 30 mph wreaking havoc and destruction all along its path.  Examiner.com soon posted a special report at 11:30 warning of the twister and showing its expected path.  It narrowly missed the town of Milliken, dumping baseball sized hail on it instead.  The twister was now a full mile wide with winds in excess of 136 mph and at 11:57am, the storm struck Windsor, home to 16,000 Coloradoans.  By the time it was done with the town, it had claimed one life, destroyed 80 homes and damaged nearly 770 others.

For a total of nearly 45 minutes the storm carved a 35 mile long path of devastation and all along its path it left the evidence – houses with nothing but a foundation left, power poles snapped like matchsticks, semi-trailers overturned like toy cars, mangled pieces of metal and shards of wood.

Tornadoes in Colorado are not uncommon with an average of 60 per year, although most do occur on the eastern plains in more rural areas.  The storm was only the second deadly tornado in Colorado in the last 10 years (the Holly tornado in 2007 being the other) but it served to highlight that the Front Range is on the western edge of Tornado Alley.  Weld County is in fact Colorado’s own tornado capital having had more twisters than any other county since 1950.

When it was over, Coloradoans showed their sense of community in helping the affected areas.  The Red Cross immediately went into action as did the state government in calling out the National Guard to help.  Donations poured in and other relief agencies provided food and shelter to those left homeless.  While the Windsor Tornado was an example of the worst of Mother Nature, the storm also showed us the best of mankind.  No other weather event comes close to being Colorado’s biggest weather story of 2008.

Below is some amazing raw video from 9News of the tornado as it moved north.

Strong winds hit Thornton and the Front Range

High winds hit the metro area on Tuesday morning.
High winds hit the metro area on Tuesday morning.

High winds have hit the Front Range with gusts exceeding 80mph in some areas.  These winds are extremely gusty and have the potential to cause damage and can make driving conditions difficult.  

A High Wind Warning remains in effect for much of the Front Range and foothills until 8:00am (see area map below).  While Thornton is not in the warning area, we have received our fair share as ThorntonWeather.com recorded a 51mph gust earlier this morning.  In the near term, west winds of 15 to 30 mph gusting to 45 mph are expected all along the I-25 corridor.  Gusts as high as 75 mph will occur near the base of the foothills and areas in northern Jefferson County, Boulder County and Larimer County in particular will receive the highest winds. 

These winds will cause blowing dust and drivers on north-south roads need to be wary as the cross winds could cause a loss of control.  It would not be surprising to hear of accidents with light weight or high profile vehicles this morning.  Power outages are of course a possibility as well. 

From the National Weather Service, here are some of the recorded gusts across the Front Range:

December 28 to January 3 – This week in Denver weather history

December 28 to January 3 - This week in Denver weather history.
December 28 to January 3 - This week in Denver weather history.

This week in Denver weather history is very interesting for a couple of reasons.  First is the two year anniversary of the holiday snow storms of 2006 as it was from December 27th to the 28th that the second major storm in a week buried the city even further in a blanket of snow.  Second, we see many occurrences of high winds, some damaging, which reminds us that the winds we have been experiencing and will continued to experience this week aren’t all that unusual. 

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.

26-28

IN 1979 A HEAVY SNOW STORM DUMPED 6 TO 10 INCHES OF SNOW OVER THE METRO AREA AND 15 TO 20 INCHES AT BOULDER WITH UP TO 2 FEET IN THE FOOTHILLS WEST OF BOULDER.  HEAVY SNOWFALL TOTALED 6.0 INCHES AT STAPLETON INTERNATIONAL AIRPORT WHERE NORTH WINDS GUSTED TO 21 MPH.  MOST OF THE SNOW… 4.8 INCHES…FELL ON THE 27TH.

27-28

IN 1997…HIGH WINDS COMBINED WITH FRESH SNOW FROM A PREVIOUS STORM CAUSED HIGHWAYS TO BECOME SLICK FROM DRIFTING SNOW AND NEAR WHITEOUT CONDITIONS IN LOCALIZED GROUND BLIZZARDS. STRONG WINDS BLEW SNOW ACROSS THE RUNWAYS AT CENTENNIAL AIRPORT…WHICH GLAZED OVER AND FORMED AREAS OF ICE.  TWO PLANES WERE DAMAGED WHEN THEY SLID OFF THE RUNWAY WHILE LANDING.  NO INJURIES WERE REPORTED.  NUMEROUS ACCIDENTS ALSO OCCURRED ON I-25 AND I-70 AS ICE FORMED UNDER THE SAME CONDITIONS.  A ROLLOVER ACCIDENT WHICH INJURED 4 PEOPLE ON STATE HIGHWAY 93 NEAR THE ROCKY FLATS ENVIRONMENTAL TEST FACILITY WAS ALSO ATTRIBUTED TO THE HIGH WINDS.  THE HIGH WINDS CAUSED AN OFFICE BUILDING AND SHOWROOM UNDER CONSTRUCTION IN GOLDEN TO COLLAPSE. THE LARGEST WALL WAS 180 FEET LONG AND 28 FEET HIGH. SOME HIGH WIND REPORTS INCLUDED:  86 MPH AT GOLDEN GATE CANYON…72 MPH NEAR CONIFER…AND 70 MPH AT JEFFERSON COUNTY AIRPORT AND THE NATIONAL CENTER FOR ATMOSPHERIC RESEARCH ON THE MESA NEAR BOULDER.  WEST-NORTHWEST WINDS GUSTED TO 53 MPH AT DENVER INTERNATIONAL AIRPORT ON THE 27TH.

As we continue on what has been a relatively dry season thus far, cold and dry are the key words to remember when it comes to January. The month is the coldest of the year and the second driest as well. Just how cold can January get? The record low temperature for each day of the month is at least 10 degrees below zero.

White Christmas for half the country as travel woes continue

Old Man Winter brought a white Christmas to much of the northern half of the United States which may be a blessing or a curse depending on your point of view.  Images released by the National Operational Hydrologic Remote Sensing Center  show that many areas that wouldn’t normally expect snow are covered in a blanket of white this Christmas.

Much of the country west of the Continental Divide will have snow or rain Christmas Day.  Areas of the Sierra Nevada and southwestern Colorado will be measuring the snow in feet.  Salt Lake City is expecting 4 to 8 inches while here in Denver we remain dry and will actually have a pretty mild day. 

In the northeast they will have a cold and blustery holiday.  Lake Erie and Lake Ontario will generate some lake-effect snows from Pennsylvania through New York and into northern New England. 

The latest cold blast to hit the nation has caused travel woes across much of it.  In Chicago, 500 flights were canceled on Tuesday stranding many travelers, some of whom won’t be able to reach their destination until today.  100 flights were canceled at O’Hare Wednesday but delays improved as the day went on.  Sadly the weather did have a more serious toll as between Tuesday and Wednesday at least 30 people were killed in crashes on rain- and ice-slickened roads across the nation’s midsection. 

Out west in Washington and Oregon, residents and government officials were wishing for a return to their normal rainy weather as they were unprepared for the snow that has fallen in recent days.  In Portland, Oregon many side streets were impassable without chains or four wheel drive.  Wednesday more snow fell followed by rain which most likely will add to the problems when it freezes tonight.

Washington Governor Chris Gregoire declared a statewide winter storm emergency saying, “A number of counties and cities are struggling to meet the problems posed by this month’s onslaught of snow and winter weather.  Snowfall has reached record or near-record level in 30 of the state’s 39 counties.”  Her proclamation will allow state agencies to support local operations including the activation of the National Guard. 

Active weather watches and warnings on Christmas Day.Here in Colorado, much of the western slope is under various types of winter weather advisories.  A Winter Storm Warning covers the western half of the state and Blizzard and Avalanche Warnings cover some areas south of I-70.  Needless to say, Christmas Day travel in the high country will be greatly impeded by these storms.  

Good weather along the eastern part of Colorado has allowed Denver International Airport to operate normally for the most part.  However, some delays were experienced for flights heading to other parts of the nation affected by the winter weather.

Dreaming of a white Christmas? The chances are slim

What are the odds of a white Denver Christmas?  Not very good.
What are the odds of a white Denver Christmas? Not 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.

CNN meteorologist calls manmade global warming theory ‘arrogant’

It would seem that the debate on global warming and manmade climate change isn't over yet.
It would seem that the debate on global warming and manmade climate change isn't over yet.

CNN weather anchor Chad Myers appeared on Lou Dobbs Tonight earlier this week and he had had some pretty stark comments on manmade global warming.  Calling the theory ‘arrogant’ and declaring that the data on which it is based short-sighted and faulty, Myers adds his voice to a growing chorus of dissenting opinions on the impact man has on the climate and is on the heels of last week’s news of 650 international scientists announcing their disagreement with the manmade global warming claims of the United Nations.

To think we could affect weather all that much is pretty arrogant.

– Chad Myers, CNN Meteorologist

Myers continued:

“Mother Nature is so big. The world is so big. The oceans are so big. I think we’re going to die from a lack of fresh water or die from ocean acidification before we die from global warming, for sure. But this is like you said, in your career; my career has been 22 years long. That’s a good career in TV. But in talking about climate, it is like having a car for three days and saying this is a great car. Yes, it was for three days, but maybe in day five, six and seven it won’t be so good. That’s what we’re doing here. We have a hundred years worth of data, not millions of years that the world has been around.”

This was a pretty interesting exchange.  Check out the video below.  You can also find a transcript here.

December 21st to the 27th - This week in Denver weather history.

Our look back in Denver weather history for Christmas week includes a number of very notable events.  One is the two year anniversary of the Holiday Blizzard of 2006.  Most notably though is the 26th anniversary of the Christmas Eve Blizzard of 1982.  More information on these and other significant events is below.  For more on the Christmas Eve Blizzard of 1982, be sure to check out an article we wrote about it.

From the National Weather Service:

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.

What are the chances the weather will kill you?

What are the odds that a weather event will be your undoing?  Image courtesy WeatherGeekStuff.com.
What are the odds that a weather event will be your undoing? Image courtesy WeatherGeekStuff.com.

In an interesting piece from the National Safety Council, they outline many of the unnatural ways you could die and what the chances are that they would actually happen. The good news is that weather most likely won’t kill you. The bad news is there are lots of other ways that you have a better chance of dying from. 

Over your lifetime, the NSC calculates you have a 1 in 22 chance (YIKES!) that you will die from something other than natural causes. Motor vehicle accidents are probably the most common way with a 1 in 84 chance you will die in a crash. Hmmm. I think I will walk home – at least then my chances jump to 1 in 267! 

As for the weather and other disasters…
  • Your chances of being struck by lightning and dying? 1 in 81,949. Pretty slim odds there. You are more likely to drown in your own bath tub (1 in 11,079). 
  • What about earthquakes, the one natural disaster that scares me more than any? 1 in 103,004 chance you will die in a temblor. That’s about the same as dying from overexertion (1 in 119,098). I guess maybe I am relatively safe from those after all, especially since I don’t live in California anymore!
  • What about the chances of dying in a major storm? Not looking too good there – a 1 in 4,361 chance you will die that way. Talk about Mother Nature’s wrath!  That’s about the same chance as you dying from choking on your dinner (1 in 4,411). 
  • Flooding can be a concern in some areas of the nation. You have a 1 in 317,595 chance of dying that way. You have a better chance of dying from electrocution from a live power source than that (1 in 36,297). 
  • All in all, the statistics say that you have a 1 in 1,749 chance of dying from some force of nature, about the same odds of dying from assault with a sharp weapon (1 in 1,817). 
I suppose those aren’t too bad of odds, especially when contrasted with every day dangers such as driving a car like we mentioned above. Other every day dangers that give you a good chance of taking a dirt nap? You have a 1 in 1,456 chance of dying in an uncontrolled building fire. Heading to the hospital? You have a 1 in 1,437 chance of dying from medical / surgical complications. That mean, neighbor dog? You have a 1 in 115,489 chance that it or another dog will kill you. 
 
In the end, weather probably shouldn’t worry you too much.  Do you have a weather or natural disaster fear?  Let us know!  Leave a comment below!
