Rain, thundershowers, flooding concerns kick off the week

Memorial Day will be a day for indoor plans in western South Dakota and northeastern Wyoming. Fog and rain will take up much of the day across the area with a few thundershowers possible along the South Dakota and Nebraska border.

Easterly winds will help upslope development of fog and showers in the Black Hills and foothills. Visibility may drop at times on roadways, slow down if conditions worsen. Temperatures will stay mainly in the 50s across much of the area with high humidity sticking around.

The main concern over the next few days is flooding. 1-2″ of additional rainfall is expected through Wednesday with some locally higher amounts possible.

Over the weekend, heavy rain fell in Ziebach and Meade Counties, bringing 1.5 to 3.4″ of rain. An areal flood warning is in effect through tonight for portions of Meade, Haakon, and Ziebach counties.

The Cheyenne River near Plainview is currently sitting in the action stage. The overall trend since last weekend shows the water levels in decline but additional rainfall this week is expected to rise levels once again.

Toward Pine Ridge, flood concerns continue along the White River. Water levels remain in the minor flood stage. An areal flood warning is in effect through Thursday afternoon.

Area wide, a flood watch remains in effect through Wednesday morning. Be mindful of areas that flood during periods of heavy rain. Always turn around instead of driving past barricades or through flooded roadways.

Once rain moves out Wednesday, drier weather returns Thursday and Friday. Isolated thunderstorms are possible in the afternoons and as we head into the weekend.
