Sioux Falls, SD
We have a mild start to the day with morning showers and t-showers in northern KELOLAND. Nothing is severe, but scattered rain chances will continue from Buffalo to Mobridge, extending east toward Aberdeen.
The main story today will be tracking the chances of severe weather. The storm prediction center has much of KELOLAND under a “slight” risk of severe storms. Large hail and damaging winds will be the main threats, although an isolated tornado can’t be ruled out in SW SD.
The SPC also has an enhanced damaging wind threat indicated in the 30% risk area, but again, this will depend on the capping inversion that will tend limit some of the storm potential south of I-90.
The initial storms West River this evening will try to move east tonight. A strong cap will make it more difficult for those storms to move east, but if they hold together, strong winds and hail will be possible.
Areas NW of Sioux Falls would be most likely to see this type of activity. We’ll be monitoring the latest high-resolution data on this scenario today on KELOLAND News.
More scattered t-storms are possible Wednesday morning across KELOLAND. Some heavy rain could accompany the strongest storms.
We’ll see a break in the rain Wednesday afternoon through Thursday, but another disturbance will give us a chance of t-storms again by Friday AM. In fact, this next system looks fairly robust and severe weather will be possible Friday night or Saturday.
It appears more scattered storms will be in the forecast next week as this active weather pattern continues. The jet stream is much farther south this June compared to 1 year ago, so an active trend will continue as long as the jet stream remains farther south.
