South Dakota Bracing for Sudden Snow Surprises

After a warm start to the week, South Dakota is in for a dramatic shift with strong winds and possible snow squalls.

When and Where

• Timing: Late Thursday night into Friday morning
• Areas at Risk: Couteau des Prairies and north-central South Dakota

The National Weather Service warns of a possible blizzard if conditions align. Even without a full blizzard, snow squalls could create dangerous driving conditions.

Temperature Drop and Precipitation

• Tuesday: Mild temperatures, rain expected
• Thursday Night: Sharp drop in temperatures, high chance of snow
• Snowfall: Up to 1 inch in some areas, especially Couteau des Prairies

What Are Snow Squalls?

Unlike regular snowstorms, snow squalls are:

• Sudden and short-lived
• Can cause whiteout conditions
• Made worse by strong winds (gusts up to 55 mph)

Safety Tips

• Stay Alert: Conditions can change rapidly.
• Know the Difference:
• Winter Storm Watch: Bad weather is possible soon.
• Blizzard Warning: Strong winds and low visibility are already happening.
• Stay Informed: Keep up with weather updates to stay safe.

The worst of the weather should pass by Friday afternoon, but light snow or blowing snow may linger.
