Sioux Falls, SD – South Dakota residents wondering when the first measurable snowfall of the 2026 winter season might arrive have an early November date to watch. Sioux Falls typically records its first accumulating snow nearly three weeks before Thanksgiving, while strong winds across the state's open plains can create hazardous winter travel conditions.
According to historical snowfall information provided for this report, Sioux Falls generally experiences its first measurable snowfall around Nov. 6. That is 20 days before Thanksgiving, which falls on Thursday, Nov. 26, this year.
When Does South Dakota Usually See Its First Snow? South Dakota's northern location and open terrain expose the state to cold air and early season winter storms.
Western South Dakota, including higher elevations of the Black Hills near Lead and Deadwood, can experience accumulating snowfall earlier in autumn.
Sioux Falls, located in Minnehaha County, provides an eastern South Dakota reference point for typical first snowfall timing.
Communities across central and northern South Dakota, including Pierre, Aberdeen and Watertown, can also encounter early season snow as colder air moves across the northern Great Plains.
Measurable snowfall is defined as at least 0.1 inches of accumulation.
Could Snow or Blowing Snow Affect Thanksgiving Travel? Historical patterns suggest that measurable snowfall before Thanksgiving is possible across South Dakota, with Sioux Falls' typical first accumulation arriving in early November.
Strong winds can create blowing snow, reduced visibility and drifting across exposed highways.
Major routes, including Interstate 90 and Interstate 29, can become hazardous when accumulating or loose snow combines with powerful winds.
Blizzard conditions depend on sustained or frequent strong winds and severely reduced visibility, not simply heavy snowfall.
However, the Nov. 6 benchmark represents historical timing, not a confirmed snowfall or blizzard forecast for 2026.
Residents across Sioux Falls, Rapid City, Aberdeen, Pierre and surrounding communities should monitor National Weather Service forecasts as November approaches.
For now, South Dakota's historical snowfall patterns point toward early November for Sioux Falls, with earlier snow possible in higher elevations and hazardous blowing snow a recurring winter concern.
