This map shows the percentage of days that a particular area had snow in North America from October 1, 2010 - March 21, 2011.


This year's decidedly un-winter-like winter brought far less snow than normal, as seen in new maps made from NASA satellite data that show the percentage of snow cover over North America.

The lack of snow brings about mixed blessings for spring: spring floods are less likely, but there will also be less snowmelt to fill reservoirs.

Data from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite was used to make the maps, which show the percentage of days in which a parcel of land was covered by snow this past winter and in the winter of 2010-11.

The deepest blues had snow cover just 10 to 20 percent of the time, while the palest blue depicts near complete snow cover for the season. Gray areas had no measurable snow.

In the winter of 2010-11, the Great Lakes, New England, the Rocky Mountains, and the Basin & Range in the West all received snow over a wider area and for longer periods of time than this past winter, as did Canada’s Alberta, Saskatchewan, and Manitoba provinces.

Most of the eastern half of the United States and southern Ontario had far less snow in 2011-12, and very little reached the South. Snowfall reached deeper into the Southwest, but was short-lived.

The overriding patterns in the atmosphere over North America during the winter were the main reason for the snow no-show.

"A major reason for the snow deficits was the persistent position of the jet stream close to the U.S.–Canadian border," climatologist Dave Robinson of Rutgers University said in a NASA statement. "This kept the cold air at bay to the north and permitted mild conditions to persist winter-long across most states. With only infrequent buckling (troughs) in the jet to the south the number and severity of winter storms was reduced — as it is the interaction of different air masses that helps spawn storms."

Information on how much snow has fallen in a given winter in a particular area is important for climatologists and hydrologists in evaluating spring flood risks and how much water will be available in a given watershed for irrigation and drinking.

"Water resource managers need this information so they can plan their reservoir heights," said Dorothy Hall, who leads the NASA team that creates the snow maps.

Forecasters with the National Oceanic and Atmospheric Administration have predicted low flood risks for areas of the country that saw devastating floods in previous years.

"For the first time in four years, no area of the United States faces a high risk of major to record spring flooding, largely due to the limited winter snowfall," NOAA said in a statement.

The agency noted that eight of 11 western states still had reservoir levels at or above the normal capacity — a residual effect of last year's thick snow pack.

Interesting, less snow, but it feels like there have been more bouts of wind, but what I noticed is on the snow days is the temp is colder than usual.

More data for the ''deniers'' to blame on faulty thermometers and weather stations!

Who can deny with such evidence?

Who can deny such evidence? Well the Governor of Texas, but he is just one of many that deny rock solid science.

OH CRAP!!! I always get into this and people deny this issue. WAKE UP IDIOTS get a flipping grip. This is REAL! I post the videos, but this is SERIOUS and for people to deny this is to deny animals the right to live!! So many are dying due to this...as well as all of the others killed due to Mankind's GREED~~~ Hugs and Thank you SOOOOOO MUCH for always posting this!!! There are so many people that say NOPE, but I have lived in So. California, it is Climate CHANGE here and this is heart hurting for me~ xxx THANK YOU SO MUCH SWEETIE!!

The sparse snow here in the Midwest is bad news, since we are already in a severe drought. Thanks Kit.

I don't need NASA or a map to inform me that there is far less snow -- I've been around a long time now, and the winters are decidedly warmer -- so let's get going and frack up the country -- what could possibly go wrong?! NOT!!!!

Oops -- thanks Kit - I hope it isn't necessary at this point in the game to post articles like this -- but I know it is -- the ignorant are always among us!

""For the first time in four years, no area of the United States faces a high risk of major to record spring flooding, largely due to the limited winter snowfall," NOAA said in a statement."

Mixed blessing that. Ever heard of the dust bowl days? Just wait until you see the breadbasket this summer. Most of which is already in drought conditions. Last year Minnesota had about 12 inches of snow, all of which melted in a day or two, so bare ground most of the winter which was also exceptionally warm, but we've had few 3 to 4 inch "storms" this year, though it rained three times in January, and although we had an exceptionally wet April last year, March for the first time had no moisture at all, not one drop, and a whole week in the 80's - also a record. And we're now in something like 16 straight months of drought conditions. South of us is worse. The topsoil will end up in California once summer hits and the winds begin blowing again. This isn't a "good" sign, far from it.

I hate to say this, Gene but perhaps that is just what it will take to make people realize our window to act is drawing to a close. The dust bowl was caused by combination of deforestation, abuse of water, and poor farming techniques. The land was reclaimed only by the Federal government instituting a policy of planting trees, control of water usage, and strict policies on farming techniques. Back then we had a man that fully understood the science and geographic phenomena that led to the causal relationships and was given the ability to act for the benefit of the public good. That man was Henry Wallace. Now we have so much negative influence by giant Mega corporate interests it's nearly impossible to get any thing done in Congress, and true leaders with the insight, knowledge and courage to act, are not in public service. The few that do have the courage of both knowledge and conviction are either ignored or their powers to act stymied by the efforts of lobbies and those in Congress beholden to those lobbies.

Hell of a way to run a country, even worse when we face such a catastrophic and impending scenarios.

If we stop wasting water on feeding animals to EAT, thereby also eliminating more Green house gases ito the atmosphere than all other contributors combined, we can SAVE EARTH and her living beings!

I've lived in Western NY all my life and survived the Blizzard of '77. When we finally were able to dig our way out of our house through the back door, my husband had to climb up to the roof to see any part of our neighborhood--and he learned that our home was no longer visible. The snow drifts had the front of our home completed buried! It took DAYS of non-stop shoveling to gain access to our neighbors --and we lived in a residential neighborhood.

We moved about ten miles north of that location a few years later, and I can't honestly say that we've ever felt the need to buy a snow blower or snow thrower. We just haven't had enough snow to justify it! Yes, things have changed dramatically. As a kid, I used to walk to school through drifts that were often waist-high, and the snow seemed to last forever. Now we have one week of sub-freezing temperatures, and then it's up into the 60's the following week! I don't know what's going on, but our climate has most definitely changed. Even here, near the Queen City of the Great Lakes, our snowfall has been rapidly diminishing over the years. I have no tolerance for deniers...

Worrying.

The US could become a dustbowl if we're not more careful of the environment.
