SPC MD 927MD 0927 CONCERNING SEVERE THUNDERSTORM WATCH 257... FOR FAR SOUTHEAST SOUTH DAKOTA INTO ADJACENT PORTIONS OF NEBRASKA AND IOWA 
Mesoscale Discussion 0927 NWS Storm Prediction Center Norman OK 0915 PM CDT Sun May 31 2026
Areas affected...Far southeast South Dakota into adjacent portions of Nebraska and Iowa
Concerning...Severe Thunderstorm Watch 257...
Valid 010215Z - 010415Z
The severe weather threat for Severe Thunderstorm Watch 257 continues.
SUMMARY...A localized corridor of higher tornado potential may persist for the next couple of hours across far southeast South Dakota into adjacent portions of Iowa and Nebraska.
DISCUSSION...Additional tornadic supercells have emerged immediately west of the Sioux Falls, SD and the I-29 corridor based on radar imagery from KFSD. Near-storm 0-1 km SRH sampled by the local VWP has recently increased to around 200 m2/s2 immediately ahead of the approaching storms. Consequently, the near-storm environment is more favorable for tornadoes than previously anticipated, though storm interactions appear to be modulating the duration of the tornado threat to some degree. Additional supercell development is noted on the southern flank of the emerging cluster, and is already showing signs of an organizing low-level mesocyclone. It appears likely that some tornado threat will likely continue for the next 1-2 hours - most likely on the southern flank of the cluster as it migrates east/southeast into far northeast NE/northwest IA. Based on the near-storm environment and observed velocity signatures, a strong tornado appears possible.

SPC MD 928MD 0928 CONCERNING SEVERE THUNDERSTORM WATCH 257...259... FOR PORTIONS OF THE MISSOURI RIVER VALLEY 
Mesoscale Discussion 0928 NWS Storm Prediction Center Norman OK 1046 PM CDT Sun May 31 2026
Areas affected...Portions of the Missouri River Valley
Concerning...Severe Thunderstorm Watch 257...259...
Valid 010346Z - 010545Z
The severe weather threat for Severe Thunderstorm Watch 257, 259 continues.
SUMMARY...The severe threat is gradually waning across far southeast South Dakota/northwest Iowa as storms continue to grow upscale. Further south, trends continue to be monitored for robust convective initiation, though confidence in storm coverage is limited.
DISCUSSION...Local radar imagery from KFSD shows continued upscale growth of initially semi-discrete supercells into a more consolidated convective band. GOES IR imagery also shows the onset of a weakening trend as cloud-top temperatures begin to warm. New cell development continues on the southern flank of the band; however, the onset of nocturnal stabilization is evident in regional web cams and by modifying the 00 UTC OAX RAOB to local surface observations. Increasing inhibition will likely begin to modulate the potential for further cell development heading later into the evening hours (especially in the absence of stronger forcing for ascent). Consequently, it appears likely that the recent weakening trend and the overall severe threat will continue to wane.
Further south, convection appears to be struggling against the aforementioned nocturnal stabilization as weak thunderstorms continue to dissipate within an hour or so after initiation. Percolating congestus is noted in GOES IR imagery west of I-29 and north of I-80 along the surface trough/dryline, and recent RRFS solutions hint at more robust initiation in this region by around 06 UTC. Given the favorable kinematic environment sampled by the 00 UTC OAX sounding, severe thunderstorms remain possible if deep convection can become established. However, given the lack of appreciable forcing for ascent and increasing inhibition, these RRFS solutions appear bullish.

SPC MD 929MD 0929 CONCERNING SEVERE THUNDERSTORM WATCH 258... FOR PORTIONS OF EASTERN KANSAS AND WESTERN MISSOURI 
Mesoscale Discussion 0929 NWS Storm Prediction Center Norman OK 1053 PM CDT Sun May 31 2026
Areas affected...portions of eastern Kansas and western Missouri
Concerning...Severe Thunderstorm Watch 258...
Valid 010353Z - 010600Z
The severe weather threat for Severe Thunderstorm Watch 258 continues.
SUMMARY...Multiple areas of thunderstorms are developing/ongoing across eastern Kansas and western Missouri. This trend will continue into the overnight. Large hail and damaging winds are the main threats, but a tornado cannot be ruled out for any storms interacting with surface boundaries.
DISCUSSION...Several areas of thunderstorms are underway across eastern Kansas and western Missouri this evening. One such area is across the Flint Hills where earlier splitting supercells occurred and produced reports of 1-2" hail (near Emporia). Additionally, a brief tornado was reported by spotters near Madison, KS (Greenwood County) as the right split interacted with a diffuse outflow boundary. The left split has since dissipated as it moved northeast toward Kansas City, but the right split is very slowly moving east along the boundary. Additional thunderstorms across the Flint Hills in the wake of the initial convection.
Additional thunderstorms are developing farther west, near Wichita, KS, and farther north to the southeast of Salina, KS. The storms near Wichita have struggled to sustain their intensity, with the storms to the north exhibiting supercellular characteristics.
Lastly, recently radar imagery is showing development to the southeast of Kansas City, MO, across portions of west-central Missouri. Although these cells have struggled through the evening, lightning has recently been observed with this activity.
Overall, the environment across eastern Kansas and western Missouri remains favorable for severe thunderstorms this evening. Thermodynamically, an impressive nocturnal CAPE reservoir remains in place with MUCAPE values in excess of 4000 J/kg across western portions of Severe Thunderstorm Watch #258. Kinematically, effective-layer shear remains between 35-50 knots across the region. Thus, the primary severe threats with any sustained thunderstorm updraft will have the potential to produce very large hail and damaging winds. Given the persistent extreme instability across the region, tornadoes cannot be ruled out with any discrete storm interacting with one of a myriad of surface boundaries (outflow, cold front, dryline, etc) across the watch.
With time, the slow movement of the storms, especially the Flint Hills cluster, should tend toward messy storm interactions and a tendency to grow upscale as updraft outflows congeal together. This may result in an increasing damaging wind potential manifest as a small MCS moving east into Missouri.

SUMMARY...A few supercells and severe multicells will be possible through the evening. Large hail, locally damaging winds will remain possible, and some tornado risk will exist particularly with storms initiating/occurring near the boundary across the region.
The severe thunderstorm watch area is approximately along and 45 statute miles east and west of a line from 30 miles west northwest of Worthington MN to 10 miles southeast of Sioux City IA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU7).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes.
&&
AVIATION...A few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 29020.
