After initial forecasts originally put the bulk of Saturday’s rain dropping on Mitchell, the National Weather Service said Mitchell came out of the weekend better than originally expected.
“The Mitchell area doesn’t really need any more water in the James River,” NWS meteorologist Lance VandenBoogart said.
Mitchell saw a total of 0.61 inches of rain according to Tim Masters, a technician with the NWS office in Sioux Falls.
According to VandenBoogart, the first models of Saturday’s storm showed the chance of 1 to 2 inches of rain landing on the Mitchell area but as it got closer to the weekend models showed the bulk of the storm shifting to the south and east.
“Two or three days out, the models showed it really over the Mitchell area. But as the system grew closer and closer, we saw the rain amounts decrease over what was originally thought (for the Mitchell area).” VandenBoogart said.
For the James River, VandenBoogart said that over the next couple of days the James River will rise just slightly by two-tenths of an inch, where it’ll remain for the next week.
“A lot of the precipitation fell south and east of Mitchell,” he said. “All things considered, not a lot of rain fell into the James River basin so you shouldn't expect a significant rise.”
Currently, the river is at 20.6 ft and is expected to rise to 20.8 by Tuesday morning.
“It should be pretty steady and you really won’t notice the change until you get out a ruler and really want to measure it,” VandenBoogart said.
Across the region, Sioux Falls received 1.1 inches of rain while areas further to the South and East of Yankton saw reports between 1.75 and 2.3 inches of rain. Huron reported 0.22 inches of rain while the NWS didn’t receive a report out of Chamberlain.
So far, Mitchell has reported 1.31 inches of precipitation for the month of March, according to Masters.
The next chance of rain is Monday night into Tuesday morning where temperatures will drop down 42 degrees overnight with highs near 60 on Tuesday according to Masters.
“That means it should definitely be rain, should look like it’ll be traditional springtime showers,” Masters said.
The James River is at moderate flood stage at 17 feet and typically begins to get into fields. At 20 feet is when the river levels can reach some county roads and 22 feet brings significant flooding, according to VandenBoogart.
