The National Weather Service Saturday morning projects that a storm capable of dropping a foot of snow on the city is coming in "slower" and "stronger" than originally predicted.

"Just because you may be waking up to only half an inch or an inch of snow on the ground, that doesn't mean the storm isn't going to happen," Meteorologist Matthew Dux said Saturday morning.

In addition to the snowfall, the area has already seen wind gusts exceeding 60 mph, and wind will continue gusting between 40 mph and 60 mph throughout the day, Dux said.

That, paired with the heavy April snow, has potential to down power lines and knock branches off of trees. Wind will also cause blowing snow, which could make travel impossible.

Because the snow is coming in slower, it will also likely linger longer, Dux said. Sioux Falls residents can expect snow to continue into Sunday morning, though the heaviest snow is expected between 11 a.m. and 6 p.m. Saturday.
