UPDATE: 8:45 pm CDT
So far, western KELOLAND has seen several rounds of severe weather, including one confirmed tornado that touched down about 23 miles NNW of Faith in Perkins County and another preliminary confirmation of a touchdown a few miles north of Pringle in Custer County.
While portions of the region have seen their severe threat diminish, others are still going to need to keep an eye on things.
A severe thunderstorm watch will remain in effect until 1 am CDT Sunday night for Tripp, Todd, and Mellette Counties. Tornado watches remain in place just to the west and as far north as Corson and Perkins Counties until 9 pm MDT/10 pm CDT Sunday.
Scattered showers and storms along an advancing line will continue to push eastward, with gusty winds and hail becoming the primary concerns as we go later into the night…though a non-zero tornadic risk will remain in place.
Stay with KELOLAND’s Live Doppler Storm Team as we go through the night for further updates.
UPDATE: 3:34 pm CDT
A tornado watch is in effect for western and portions of west-central KELOLAND until 10 pm CDT/9 pm MDT Sunday night.
Scattered showers and thunderstorms are continuing to fire up in western South Dakota, interacting with a favorable air mass for storms to generate some rotation. Any severe storm that pops up is capable of producing a tornado, but the set-up in the atmosphere this afternoon can potentially help this along…especially with any supercells that are able to develop.
Remember, a tornado watch means that conditions are favorable for thunderstorms to form tornadoes. Should radar pick up on a rotation signature or one be observed, a tornado warning will be issued.
Keep an eye out for future updates.

The threat for severe weather will be in place as we head into the afternoon and evening, especially in central and western KELOLAND.
Low pressure centered well to our west will organize and move northeastward through the day, pushing a warm front northward through the region. An associated boundary will then move eastward as we head into the afternoon and evening. This will be our focal point for concern with regard to severe weather.
An “Enhanced Risk” for severe weather is in place for portions of central and western KELOLAND for the afternoon and evening, with a “Slight Risk” in place as far east as the James River valley. A “Marginal Risk” for severe weather will be in place along the I-29 corridor, valid mainly for the overnight time frame.
The best chance to see severe weather West River will be from the early afternoon through the evening, as a line of strong to severe storms pushes to the east toward the Missouri River.
All forms of severe weather, from wind to hail and even a few tornadoes, are on the table.
As a result, it is important to not only know where these storms are, but where you are as well. Make sure you are familiar with the county that you reside in as well as any surrounding counties. A trio of maps will be provided below.
Be sure to keep an eye out for any and all updates both on-air and online, have your StormTracker App ready to go on your phone, and have a NOAA weather radio on stand-by as well.
