NWS: Wind speeds up to 100 mph caused damage in southeastern South Dakota
Most of the damage across southeastern South Dakota was caused by heavy winds, according to the National Weather Service.
It'll take at least a day for the NWS to compile the exact amount of damage suffered across the region and another few days to figure out if the high winds were a derecho-like weather event, Philip Schumacher, a forecaster, said.
"(The damage) was pretty wide-spread," he said, adding that they had received reports of downed trees, roofs blown off of buildings, out-buildings being destroyed and multiple semi-trucks tipped over from across Yankton, McCook, Brookings, Minnehaha and Bon Homme Counties.
Multiple folks were out cleaning up from damage between the storms in Sioux Falls and the surrounding region on Thursday evening.
In Brookings County, the hospital had an influx of patients during the storm and a roof was blown off a church, according to the emergency manager.
While a tornado was reported in Castlewood by the Aberdeen NWS, there were a few false tornado reports in southern South Dakota. Schumacher explained that the dust that came in with the storm looked like it was swirling in some cases and people might have mistaken it for a tornado.
Wind speeds over 100 mph in some places
Tripp experienced a straight line wind speed over 100 mph, Schumacher said.
A 107-mph wind gust was clocked in town, according to the NWS.
Other high wind gusts include Madison (97 mph) and Huron (90 mph), according to the NWS. Three miles south of Sioux Falls a 78 mph wind gust was clocked.
Too early to tell if winds were derecho-like
Schumacher said it would take a few days to compile the data that the storm produced derecho-like winds.
The next steps are to create a chain of reports from Nebraska, South Dakota, North Dakota and Minnesota to see what kind of patterns were experienced during the severe weather, Schumacher said.
Thursday broke temperature record
Before the storms started Thursday, it had been hot and humid.
The heat broke an over-100 year record, according to the NWS. The high recorded Thursday was 93.
The previous record was 93, set in 1907, according to the NWS.
