February 1st

Local and Regional Events:

February 1, 1969:

Across central and eastern South Dakota, February 1969 contained a variety of winter weather causing many difficulties. Glazing due to heavy fog and drizzle periodically formed on utility lines causing numerous broken power lines. Periodically, strong winds caused widespread blowing and drifting snow resulting in many closed roads. Snowplows would open the roads and often drifting snow would close the roads again. Frequent uses of pusher type snowplows piled banks of snow 20 to 30 feet along the roads and it became impractical to open roads with this type of snowplow. Several rotary snowplows were flown in from military airbases outside of the state to open some of the roads in the eastern part of the state. Numerous school closings occurred during the month due to snow blocked roads.

 

February 1, 1989:

Four to eight inches of snow fell across western and northern South Dakota. Winds of 25 mph and subzero temperature produced wind chills in the 50 to 80 below zero range. Several schools were closed across the area due to the dangerous wind chills. The storm continued into the 2nd.
 

February 1, 2012:

The image below is a 1000m resolution, "true color" image from the MODIS satellite valid February 1st, 2012. A couple interesting features are noted on the image described below:

 

Areas in "brown" are predominantly void of snow. As such - a vast majority of South Dakota is completely snow free! Obviously, this is quite rare for the 1st of February. The "brown ground" is able to absorb much more solar energy, which allows temperatures to warm. This is a major reason why temperatures have remained above normal.

Residual areas of snowcover (white) are confined to the Black Hills region in western South Dakota and the Glacial Lakes region in northeastern South Dakota.

 

A large section of Lake Oahe north of Pierre is free of ice (dark blue color).

U.S.A and Global Events for February 1st:

1947: On this date through the 9th, a memorable blizzard occurred in Saskatchewan, Canada. All highways into Regina were blocked. Railway officials declared the worst conditions in Canadian rail history. One train was buried in a snowdrift over a half mile long and 36.7 feet deep.

1955: Seen first as a "well defined cone-shaped funnel" over the Mississippi River, this F3 tornado cut a path from Commerce Landing to Clark in northeastern Mississippi. This tornado killed 20 and injured at least 141 individuals. Most of the deaths were in a plantation school. The following is from Thomas Grazulis, "Significant Tornadoes 1680-1991" book: "Despite the fact that a funnel was seen, that heavy objects were thrown long distances, and that the tornado was in a forecast box, the event was not officially called a tornado. A survey team state that since all debris was thrown in one direction, the event should not be listed as a tornado." Click HERE to read more about this event from the Monthly Weather Review.
