Blizzard of '66

One of the most severe blizzards on record to impact the Northern Plains occurred 50 years ago between March 2-5 of 1966.  The blizzard was particularly memorable for its long duration, as well as for its very heavy snowfall totals of  20 to 30 inches in some locations and wind gusts exceeding 70 mph at times.  Snowfall totals reached as high as 38 inches, with drifts 30 to 40 feet high in some locations. 

Nine people were killed across North Dakota (5) and Minnesota (4) on account of the blizzard, another 10 people died in South Dakota. A few of the fatalities were from overexertion from shoveling snow, while other deaths occurred as a result of becoming disoriented while out in the treacherous blizzard conditions.  In addition, tens of thousands of livestock perished in the storm. 

Transportation became impossible, with schools and businesses shut down across the area, and power and telephone service outages which lasted for many days.  

The iconic photo of North Dakota DOT employee, Bill Koch (below), standing next to a set of power lines, was taken by fellow ND DOT employee Ernest Feland on 9 March 1966. This photo and many others which were taken by Bill and Ernest in the days following the storm are available in the North Dakota State Historical Society and NOAA/NWS archives. 

 

Meteorological Synopsis

An intense "Colorado Low" weather system lifted into eastern South Dakota early on March 3, 1966, and slowly progressed into central Minnesota on March 4.  These type of weather systems are capable of producing very heavy precipitation, as abundant moisture can be transported northward ahead of the strong low pressure systems.  With cold enough temperatures, heavy snow and very strong winds often occur to the northwest of the track of the low pressure system, as was the case with this blizzard.  

Snow began in southern North Dakota during the morning of March 2, and spread northward into March 3.  At Fargo, the visibility remained one quarter mile or less for over 30 consecutive hours from March 3-5, coinciding with strong northerly winds gusting frequently over 40 or 50 mph. 

Unlike many of the "killer blizzards" which had previously occurred in the Northern Plains [Schoolhouse Blizzard, 11-12 Jan 1888; Armistice Day Blizzard, 11 Nov 1940; and Ides of March Blizzard, 14-15 Mar 1941], temperatures were relatively mild during much of this blizzard.  At Fargo, temperatures held steady in the 20s during the start of the blizzard, falling into the teens during the height of the blizzard, when winds were strongest and visibility lowest.  By the time the blizzard was winding down, temperatures had dropped into the single digits. 

At Grand Forks, 27.8 inches of snow was measured, with the heaviest snow falling on March 4, when 17.0 inches fell.  For Grand Forks, the 17.0 inches on March 4 set a record for most snowfall during one calendar day, while the 27.8 inches for the blizzard as a whole still remains the heaviest event total snowfall on record in Grand Forks.  

Finally by later on March 5, the low pressure system began to move away, with winds subsiding, and colder subzero temperatures moving into the region. Below is the surface weather map valid at 12 a.m. on March 4th, 1966.

Frequently Asked Questions About SkyWarn

What is SKYWARN?
    

  • Skywarn (formed in the early 1970s) is the National Weather Service (NWS) program of volunteer severe weather spotters. Skywarn volunteers support their local community and government by providing the NWS with timely and accurate severe weather reports. These reports, when integrated with modern NWS technology, are used to inform communities of approaching severe weather. The focus of Skywarn (and of the NWS) is simple...to save lives and property.

    Since the mid 1990s, the WSR-88D (Doppler Weather Radar) has provided valuable information to area forecasters...with better detection of severe storm phenomena and more accurate and timely warnings. However, even with the advance in technology... "ground truth" is still a very important part of the warning process. "Ground truth" is what is actually occurring. Is the storm tornadic? Is it producing large hail? How about damaging winds? Most of the "ground truth" is provided by trained storm spotters (through Skywarn)...or the "eyes of the NWS."

     Who Are SKYWARN Severe Weather Spotters?
     

  •  SKYWARN spotters across North Dakota and Minnesota consist mainly of amateur radio operators, emergency response officials, and trained public responders. The vast majority of those involved are volunteers who provide this valuable public service. These Spotters donate their time and equipment to help us (the NWS) get warnings out to the public, and to get public reports of severe weather back to the NWS ...by any means possible.

    Spotters are generally self-activating... meaning they pay attention to the latest Forecast, Convective Outlook, and Watch or Warning... then they observe and report on the occurrence of severe weather from wherever they may be located. 

    How can I get involved?
      

  •  Every year the National Weather Service in Grand Forks conducts both "basic" and "advanced" spotter training classes. Individuals are taught the basics of thunderstorm development, storm structure, what constitutes severe weather, and how to report this information. Advanced classes consider more extreme storm features to look for and where to find them. Additional information on reporting and basic severe weather safety are also covered.

    Each class, Basic and Advanced, is a multi-media presentation which includes detailed video. Classes are typically scheduled back-to-back on the same evening. Each class typically takes around 75 minutes, with about a 15 minute break for questions and refreshments. New Spotters are encouraged to attend the Basic Class while veteran Spotters may chose to attend the Advanced Class. To find out when a class will be given near you, Click Here
     


Area Contacts for SkyWarn or Amateur Radio Information

Contact your local County Emergency Manager in North Dakota  or in Minnesota  for location and time of the SKYWARN training in your county this spring.

For additional information on the SKYWARN program, contact Gregory.Gust@noaa.gov

The National Weather Service will typically issue a warning for one or both of the following reasons; Doppler radar detects severe weather or SKYWARN spotters report severe weather. If a warning is issued for your location, you are in danger and need to seek shelter.

The biggest supporters of the SKYWARN program are emergency response officials and amateur radio operators. One of the best ways to get involved is to talk with an amateur radio operator. If you have a scanner, tune in to a local amateur radio SKYWARN net (see list below) to get a feel for what is involved.
