Live updates: NWS says severe thunderstorm watch possible for Sioux Falls

Update as of 3:50 p.m. Tuesday: The NWS has stated the greatest threat for severe weather has shifted to northern Iowa for now.

"Storms remain capable of producing gusts up to 70 MPH, quarter to 2 inch hail, and locally heavy rainfall," the post from the NWS on X states.

Update as of 2:45 p.m. Tuesday: The NWS says it is watching an area around Sioux Falls and to the east where a severe thunderstorm watch may be possible as storms continue to fire up Tuesday afternoon.

A watch simply means the components are there for something to happen, while a warning means something is happening.

"Given the storm mode and modest buoyancy, damaging winds appear to be the most likely threat," the forecast states. "However, occasional hail and a brief tornado will also be possible with any embedded supercell/bowing structures able to develop. Buoyancy decreases farther east, indicating some uncertainty on the coverage and timing of the severe risk. Still, mesoscale trends suggest further destabilization is likely and a downstream severe risk may develop. With this in mind, a severe thunderstorm watch is possible."

The timing of the potential watch is unclear.

Sioux Falls School District stated on social media that middle and elementary school students may be delayed headed home.

"The Weather Service indicates the greatest threat of severe weather did not materialize in Sioux Falls," the post reads. "We will begin our bus routes at approximately 3 pm, so there will be a slight delay in getting elementary and middle school students home. High School dismisses at normal time."

Updated as of 1:45 p.m. Tuesday: A tornado watch has been issued for areas just below the southern South Dakota boarder in counties between Nebraska and Iowa until 10 p.m., according to the NWS.

It's unclear at this time whether the watch could be extended north as storms develop along I-29.

Update as of 1:35p.m. Tuesday: Officials with the Sioux Falls School District posted on social media that weather could cause challenges to school dismissal times Tuesday. "SFSD will make plans with your child's safety as our highest priority," the post states. "If there are changes, parents/guardians will be contacted immediately. We ask that you please monitor your phone and email closely."

Update as of noon Tuesday: As storms become more linear along I-29, residents should expect severe weather threats to include damaging winds of up to 70 mph and isolated tornadoes, according to NWS.

No watches or warnings have been issued at this time.

Earlier story: Areas in and around Sioux Falls will see two rounds of possible strong to severe storms Tuesday afternoon, according to the National Weather Service.

Round one is expected to hit between 10 a.m. and 2 p.m. And while the severe threat is low, hail up to quarter size is possible. Round two, expected between 2 and 4 p.m. through 7 p.m., is expected to develop near the Interstate 29 corridor and will bring a threat of large hail and damaging winds.

"A few tornadoes and/or minor flooding from heavy downpours are secondary threats," the NWS forecast states. "Storms may be moving fast, so be prepared to seek shelter quickly."
