South Dakota Faces Late-Season Snowstorm: Impacts and Preparations
As April begins, South Dakota finds itself shivering in the grip of a formidable late-season winter storm. The state’s residents, who are no strangers to weather extremes, are facing an unusual mix of snow, sleet, and freezing rain. This weather event poses a significant challenge, not only because of its timing but due to its potential impacts across the region.
The storm is set to bring a variety of wintry conditions, creating hazardous travel scenarios, especially during the critical Thursday morning commute. According to the National Weather Service in Sioux Falls, the northwest part of the state is expected to see the heaviest snowfall, with accumulations ranging from 4 to 8 inches. In particular, areas like Buffalo Ridge are anticipated to receive the most substantial snow totals.

Residents of east-central South Dakota and parts of southwestern Minnesota could face another peril with significant icing. Freezing rain accumulations are expected to reach between a quarter to half an inch on elevated surfaces like power lines and trees, potentially leading to power outages and tree damage.
The anticipated wintry mix is a result of lingering cold air and fast-moving low-pressure systems, colloquially known as clippers, sweeping southeast from the Rockies. These clippers are notorious for drawing moisture from the Gulf of Mexico and the southern United States, which interacts with the entrenched cold air to produce snow, sleet, and freezing rain across South Dakota.

Travel Precautions: The adverse weather conditions present clear hazards on the roads. Gusty winds could blow snow around, leading to localized whiteout conditions even where snow accumulations remain light. Residents are advised to stay updated with weather alerts, particularly if they plan to be on the road during peak wintry conditions.
The transition of precipitation will begin across the northern half of South Dakota on Wednesday evening, initially manifesting as rain before turning into a wintry mix overnight. The most intense period of the storm will coincide with the Thursday morning commute, adding to the risk of slick and icy driving conditions.
For residents accustomed to South Dakota’s harsh winters, it’s worth noting that the average last snowfall typically occurs in early April, but historical records reveal snow has fallen as late as mid-May. This event, while unusual, serves as a stark reminder of the volatile nature of weather in the Northern Plains.
With temperatures expected to remain below average, highs will linger in the 30s while overnight wind chills compound the cold. The National Weather Service predicts further disturbances later in the week, which could bring additional snow and wintry precipitation to the region.

Stocking up on essentials, ensuring proper insulation for homes, and preparing vehicles for potentially treacherous travel are some recommended steps. Additionally, staying informed through reliable weather updates and alerts from the National Weather Service is crucial for safety.
As the people of South Dakota brace for this late-season winter storm, community resilience and preparedness remain at the forefront.
