A strong line of storms raced across KELOLAND last evening and overnight. We have several reports of strong winds with this line, but you can see how the areas of rain fell apart as they moved into eastern KELOLAND.
Each dot on this map below represents a severe weather report. The Custer area was hit particularly hard.
We can confirm at least 1 tornado just south of Custer.
2 more tornadoes were reported in Perkins County east of Bison.
Strong winds around 80mph blew several vehicles off of I-90 in the Presho area.
The rain was welcome news as Rapid City picked up around 1″. The numbers were much lower East River, with a few exceptions around Brookings and Marshall.

Futurecast shows widespread areas of rain late Wednesday into Thursday across the northern plains. This system will provide an opportunity for some much-needed moisture relief. We will continue to watch the pattern, but .50″ to 1″ rain totals are on the table.
For today, highs will be in the 80s for many areas with a stronger wind from the southwest during the afternoon.

The weather looks a little warmer by the start of Memorial Day Weekend.
