March 1 to March 7 - This week in Denver weather history
Looking at this week in Denver weather history, it is easy to see why March is known as Denver’s snowiest month. There are numerous instances of major winter storms dumping snow on the city that was measured not in inches – but feet!
From the National Weather Service:
28-1
IN 1875…6 INCHES OF SNOW FELL FROM 3:15 PM ON THE 28TH TO 1:00 AM ON THE 1ST. PRECIPITATION FOR THE TWO DAYS WAS 0.50 INCH.
29-1
IN 1896…SNOWFALL TOTALED 5.5 INCHES IN THE CITY. NORTHEAST WINDS GUSTED TO 24 MPH.
IN 1948…SNOWFALL TOTALED 5.9 INCHES IN DOWNTOWN DENVER. NORTH WINDS WERE SUSTAINED TO 15 MPH.
1
IN 1904…WEST WINDS WERE SUSTAINED TO 42 MPH WITH GUSTS AS HIGH AS 58 MPH. THE CHINOOK WINDS WARMED THE TEMPERATURE TO A HIGH OF 67 DEGREES.
IN 1906…SNOWFALL WAS HEAVY AND TOTALED 7.5 INCHES OVER DOWNTOWN DENVER. NORTHEAST WINDS WERE SUSTAINED TO 37 MPH.
IN 1940…SNOWFALL WAS HEAVY AND TOTALED 7.7 INCHES IN DOWNTOWN DENVER.
IN 1943…6.0 INCHES OF SNOW FELL OVER DOWNTOWN DENVER. NORTH WINDS WERE SUSTAINED TO 19 MPH.
Want to be an official storm spotter or maybe just want to learn more about severe weather? Here’s your chance!
We have written before about the great opportunity the National Weather Service provides by giving storm spotter training during the start of the severe weather season. That time is now here and training sessions start in the coming week and new sessions have been added since we last reported on the topic.
The storm spotter program is a nationwide program with more than 280,000 trained spotters. These volunteers report weather hazards to their local National Weather Service office providing vital information when severe strikes. Data from spotters include severe wind, rain, snow measurements, thunderstorms and hail and of course tornadoes.
Storm spotters are part of the ranks of citizens who form the Nation’s first line of defense against severe weather. There can be no finer reward than to know that their efforts have given communities the precious gift of time–seconds and minutes that can help save lives.
By completing one of these training classes you can become an official storm spotter. When severe weather strikes, you can report it by calling a special toll free number or submit your report via the National Weather Service’s website.
These are great sessions for anyone wanting to learn more about the severe weather we experience in Colorado, whether you want to be an official spotter or not. All training is free. Topics include:
Denver and Thornton's March 2009 climatological preview
March in Denver typically means frequent and rapid weather changes. The days grow longer and we start enjoying more sunshine and sometimes summer-like weather. However, on occasion arctic air masses can still force their way south into Colorado dropping temperatures quickly and markedly.
These changes are due to Marches “in between” status – elements during the month have much in common with winter and spring. In addition to arctic fronts, Pacific storms frequently move across Colorado from the west and warm moist air streams up from the Gulf of Mexico northeastward into the state. When these cold fronts collide with the warmer air masses the result can be some crazy weather.
A recent analysis of climate models shows they are falling outside acceptable scientific limits.
Last month former vice president Al Gore made a well publicized appearance before a Senate committee warning of the dangers of global warming. Lesser known is the appearance of a climatologist before a House subcommittee two weeks later that called into question the models on which anthropogenic [manmade] global warming advocates use to base their assertions on.
We include his resume as it is significant because it shows that this is someone with a deep background in climatology and a wealth of experience. When someone of this caliber discusses climate change and anthropogenic global warming we can and should take notice.
In testimony to the U.S. House of Representatives Subcommittee on Energy and Environment, Dr. Michaels testified on the little known fact that the scientific models used to predict global warming are starting to fall outside acceptable scientific limits. They have been unable to accurately predict temperature increases and when used to model historical increases, they fail as well.
February 22 to February 28 - This week in Denver weather history.
Our look back at this week in Denver weather history contains much of what you would expect to see this time of year – high winds, snow storms, and cold but also a rare February thunderstorm.
21-22

The Weather Channel's new season of Storm Stories will feature the Windsor Tornado from May 2008. This scary image was taken by the webcam of MyWindsorWeather.com as the twister tore through the town on May 22, 2008.
This Sunday, February 22nd at 6:00pm MST, the Weather Channel will premiere the new season of its series Storm Stories. Most notably, the first episode will highlight a weather event from last year that struck very close to home – the May 22nd Windsor Tornado.
For those that haven’t seen Storm Stories, it is an exciting, sometimes scary and sad series discussing significant weather events as seen through the eyes of those that experienced it firsthand. For the Sunday episode, renowned storm tracker Jim Cantore from the Weather Channel will tell the story of the twister using footage from a variety of sources, including the video most have seen from KUSA (see below).
The kickoff of the new season of Storm Stories is actually the beginning as well of the Weather Channel’s ‘Tornado Week’ in which twisters are front and center. Other episodes of note during the week:
Monday – the “Parkersburg, IA, Tornado” on May 25, 2008, killed seven people and demolished the southern half of the town; first-hand accounts are given by residents.
Tuesday – the “Greensburg, KS, Tornado” on May 5, 2008, wiped out the entire town. The story is told through the experiences of next-door neighbors who saved a mother and her baby from the rubble.
Wednesday – “Super Tuesday” tornadoes cut a swath over a wide area Feb. 5, 2008; touching stories come from people that were affected in Arkansas, Kentucky and Tennessee.
Thursday – the “Boy Scouts Tornado” hit the Little Sioux Scout Ranch in western Iowa last June, catching everyone off guard. The surviving scouts are forced to put their training to use in the midst of a terrifying situation to help keep injured scouts alive in the aftermath.
Hot or not? Are the global climate models accurate or are they full of hot air?
The science behind the theory of anthropogenic global warming (AGW), or manmade climate change, has been said to be ‘settled’. The United Nation’s Intergovernmental Panel on Climate Change (IPCC), Al Gore, and Dr. James Hansen make up a triumvirate of climate change advocates. Wielding studies, computer models, and various charts and analyses, they believe man is heading down the road to self-destruction of we do not reverse course immediately and do everything and anything to stop what they believe is an unnaturally warming climate.
We continue our analysis of not only the battle between Dr. William Gray and Dr. James Hansen but the larger issue of anthropogenic global warming. In his letter Dr. Gray raises some very interesting arguments about Hansen’s research and about the science behind the theory of AGW. Today we take a closer look at the science as Dr. Gray sees it.
February 15 to February 21 - This week in Denver weather history.
Wind, wind and more wind. Sounding like a broken record, we see that mentioned many times in our look back at this week in Denver weather history. There is of course other common weather conditions for this time of year including blizzards and arctic cold.

IN 1960…HEAVY SNOWFALL TOTALED 6.1 INCHES AT STAPLETON AIRPORT.
IN 1965…5.4 INCHES OF SNOW FELL AT STAPLETON INTERNATIONAL AIRPORT BEHIND A COLD FRONT. NORTH-NORTHEAST WINDS GUSTED TO 32 MPH. WINDS WERE STRONG AND GUSTY ALL DAY AND CAUSED CONSIDERABLE BLOWING SNOW…CONTRIBUTING TO HAZARDOUS DRIVING CONDITIONS MAINLY TO THE EAST OF DENVER.
IN 1984…A SNOW AND WIND STORM HOWLED ACROSS EASTERN COLORADO CLOSING I-70 EAST OF DENVER. THIS WAS THE SECOND BLIZZARD IN LESS THAN 4 DAYS. ONLY 0.5 INCH OF NEW SNOW FELL AT STAPLETON INTERNATIONAL AIRPORT…BUT NORTH WINDS GUSTED TO 51 MPH.

IN 1910…WEST WINDS WERE SUSTAINED TO 42 MPH.
IN 1986…HIGH WINDS BATTERED THE FRONT RANGE FOOTHILLS. A WIND GUST TO 95 MPH WAS RECORDED IN BOULDER…BUT WINDS OF 60 TO 80 MPH WERE COMMON IN AND NEAR THE FOOTHILLS. IN AURORA…AN AUTOMOBILE DEALERSHIP LOST A LARGE PLATE GLASS WINDOW. SOUTHWEST WIND GUSTS TO 44 MPH WERE RECORDED AT STAPLETON INTERNATIONAL AIRPORT. THE STRONG WINDS WARMED TEMPERATURES. A RECORD MAXIMUM TEMPERATURE OF 66 DEGREES AND A RECORD HIGH MINIMUM TEMPERATURE OF 37 DEGREES WERE RECORDED AT STAPLETON INTERNATIONAL AIRPORT.
The new exhibit will cover the entire gamut of major natural disasters including earthquakes, hurricanes, tornadoes, and volcanoes. A special ‘Colorado Connections’ section will take a look at the Colorado’s volcanic history as well as the various types of severe weather that affect the state. Drought, floods, wildfire, blizzards, climate change and tornadoes are all discussed in depth.
According the museum:
From earthquakes and volcanoes to hurricanes and tornadoes, nature’s forces have shaped our dynamic planet. Throughout history, these catastrophic phenomena have affected people around the world. Now, uncover the causes of these natural disasters and find out how people cope and adapt in the aftermath. In this captivating, interactive new exhibition all of nature’s power is on display at the Denver Museum of Nature & Science.
In addition to the exhibits, the museum has lined up a great slate of additional events including lectures on the following:
Grand Canyon Adventure: River at Risk
Storm Chasing
Natural Disasters on Other Planets
Natural Disasters in Film
Also not to be missed are tours they have arranged for:
NCAR Mesa Lab in Boulder
National Oceanic and Atmospheric Administration (NOAA) in Boulder
Dr. William Gray is a vocal opponent of the anthropogenic global warming theory and recently took issue with Dr. James Hansen of NASA's GISS.
Last week we wrote about an extremely strongly worded letter from William Gray to the American Meteorological Society (AMS) objecting to their awarding James Hansen their highest award. This letter pits two of the giants in meteorology and climatology against each other in the debate over manmade climate change and global warming.
The letter itself (available here on icecap.us) takes issue with some of the decision making processes within the AMS which is not particularly relevant to us. What is revealing however is Dr. Gray’s arguments against the global warming theory and Dr. Hansen’s research. Today we will take a look at the discussion in the letter about Dr. Hansen himself and his credentials.
For those that aren’t familiar with him, Dr. Gray is a Professor Emeritus of Colorado State University who is best known for his hurricane forecasts. He is a highly trained and respected meteorologist with decades of practical experience in monitoring the earth and its climate.
In the letter he points out that Dr. Hansen, head of NASA’s Goddard Institute for Space Studies (GISS), is not a trained climatologist nor a meteorologist. His formal background is actually in astronomy which does make one wonder how he has become one of the primary mouthpieces for anthropogenic global warming (AGW), or manmade climate change.
