Wednesday (June 21) could shape up to be another interesting weather day in the Sioux Falls and adjacent regions. Look for early trends to establish severe storm potential.

Conditions could be ripe for the next round showers, however KDLT News meteorologist Brandon Spinner offers a clue on what could either make the afternoon sizzle or fizzle.

“It’s dependent on our morning. Humidity will bring in a chance of rain (after sunrise). The quicker that rain is out of here, the better the chance for some afternoon severe thunderstorms. If that rain lingers until (mid-morning) and we still have cloud cover until about noon, that diminishes our severe weather chances.”

Should the correct circumstances take place, Spinner says the area could see the full extent of nasty weather.

“That could bring us tornadoes, large hail and damaging winds for southeastern South Dakota, northeast Nebraska and northwestern Iowa. It will be hot and humid, but the nasty weather depends on how long that cloud cover sticks around.”

If anything does generate, the most likely time period for storms would be from 6:00 PM to 9:00 PM. Overall daytime highs will likely reach the upper 80’s to lower 90’s with dew points in the 70’s.
