Forecasters Warn of Big Snowfall in Southeast South Dakota

By | December 29, 2015

A major winter storm impacting the central U.S. is not expected to cause major problems in the Dakotas, but it’s likely to add to what already has been a busy year for snow removal in South Dakota’s largest city.

Sioux Falls has received just under 30 inches of snow from three big storms the past two months. That’s just 2.5 inches shy of the city’s snowfall total for all of last winter, and the city is expected to get 6 to 8 inches more by the end of Tuesday, according to the National Weather Service.

“I would expect that by this time tomorrow, we’ll have more snowfall this (winter) than we did last year,” NWS meteorologist Todd Heitkamp in Sioux Falls said.

City Street-Fleet Manager Galynn Huber said he already has had to ask the City Council for more money for snow removal this winter — up to an additional $2 million to augment the $7.2 million budgeted through the end of the calendar year.

Sioux Falls averages about four snowfalls over more than half a foot each winter, and this winter there’s already been three of those. Huber attributes it to the El Nino, or warming of the tropical Pacific that affects weather worldwide, which he said is bringing more Pacific moisture into the region.

“It’s been a very active winter for us,” he said.

A succession of severe weather events across the country in the last week has led to at least 43 deaths. The latest storm was causing problems from Texas to the Great Lakes and clipping the northern Plains, where snowstorms typically sweep in from the Rockies or Canada.

“It’s not your typical snowstorm. We’re actually kind of pulling a piece of energy from that major system in the southern and central Plains back into the northern Plains,” said Todd Hamilton, a weather service meteorologist in Bismarck. “It’s kind of a weird little system.”

The National Weather Service issued a winter storm warning for extreme southeastern South Dakota into Tuesday, with up to 10 inches of snow expected. Winter weather advisories were posted for much of the rest of eastern South Dakota, with 3-6 inches of snow likely. The system also was expected to drop a few inches of snow in southern North Dakota.

However, forecasters said the storm shouldn’t cause major problems in either state, despite gusty winds that could accompany the snow.

“We don’t think it’s going to cause severe whiteout conditions,” Heitkamp said.
