SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0812 PM CDT Sun Jun 21 2026 Valid 220100Z - 221200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FOR SOUTHWEST KS INTO NORTH-CENTRAL OK... ...SUMMARY... Tornadoes (possibly strong) and damaging winds remain possible this evening into parts of the Mississippi and Ohio Valleys. A swath of severe gusts (possibly greater than 75 mph) appears possible later tonight from southwest Kansas into central Oklahoma. ...Mid MS Valley into the Ohio Valley... An MCV moving across IN will eventually encounter weaker low-level moisture and instability with eastward extent. However, a long-lived storm cluster may continue eastward toward parts of southwest OH and eastern KY, before a definitive weakening trend occurs. Damaging wind and embedded tornadoes will remain possible with the primary storm cluster until weakening occurs. Semi-discrete cells and small clusters trailing the MCV will also continue to pose a threat of tornadoes (possibly strong) and damaging winds through the evening, within a moist and favorably sheared environment. See MCD 1237 for more information. ...Central High Plains into OK and southern MO... Widely scattered storm development is underway near a surface boundary draped from northwest OK into southeast KS/southwest MO. While large-scale forcing is generally modest at best, MLCAPE of 2500-4000 J/kg and effective shear of 40+ kt are conditionally quite favorable for organized storms. A few supercells may persist along the front through the evening, with a threat of large to very large hail and localized severe gusts. Also, while low-level flow is weak, vorticity and backed surface winds near the boundary could support some tornado potential, if a robust supercell can become established. Farther northwest, a supercell cluster is ongoing across western KS this evening. This cluster will continue to pose a threat of large to very large hail, severe gusts, and possibly a tornado through the evening. See MCD 1239 for more information regarding the short-term threat. Short-term guidance (notably the HRRR and RRFS) suggests that this cluster will continue to grow upscale, and potentially evolve into an MCS that will move southeastward across southwest KS into northwest and central OK, with threat of severe gusts (potentially above 75 mph) through the overnight hours. This evolution appears plausible, if evening convection across northwest OK is not too disruptive to the environment. Given the very favorable midlevel lapse rates on the 00Z DDC and OUN soundings, rich moisture, and strong instability and deep-layer shear, a 30%/CIG1 wind area was added from southwest KS into central OK. ..Dean.. 06/22/2026 Read more

MD 1239 CONCERNING SEVERE THUNDERSTORM WATCH 367... FOR PORTIONS OF EXTREME SOUTHEAST COLORADO INTO WESTERN KANSAS
Mesoscale Discussion 1239 NWS Storm Prediction Center Norman OK 0718 PM CDT Sun Jun 21 2026 Areas affected...portions of extreme southeast Colorado into western Kansas Concerning...Severe Thunderstorm Watch 367... Valid 220018Z - 220145Z The severe weather threat for Severe Thunderstorm Watch 367 continues. SUMMARY...Severe wind and hail remain likely with an ongoing line of storms, particularly with embedded supercell structures. A tornado remains possible, and an organized MCS wind swath could develop. DISCUSSION...Supercell structures have gradually merged into an MCS over the past hour. Despite a linear appearance to the broader region of storms, the MCS is flanked to the east by a dominant supercell with a prevalent mesocyclone. A wet rear-flank downdraft associated with this supercell appears to be merging with another embedded cold pool surge to the southwest, which suggests that a smaller scale but organized swath of severe (50+ kt) gusts may be developing. Until then, the stronger storm cores with embedded supercells may support severe hail, and a tornado remains possible with any longer-lasting mesocyclone. The MCS is preceded by 3000-4000 J/kg MLCAPE and 50-60 kts of effective bulk shear, suggesting that the severe threat may last for several more hours. If a prominent bow echo can develop, gusts over 75 mph will also be possible. ..Squitieri.. 06/22/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...ICT...DDC...GLD...PUB...

MD 1241 CONCERNING SEVERE POTENTIAL...WATCH NEEDED SOON FOR PORTIONS OF NORTHERN KENTUCKY
Mesoscale Discussion 1241 NWS Storm Prediction Center Norman OK 0802 PM CDT Sun Jun 21 2026 Areas affected...portions of northern Kentucky Concerning...Severe potential...Watch needed soon Valid 220102Z - 220200Z Probability of Watch Issuance...95 percent SUMMARY...A new tornado watch likely will be needed across portions of northern Kentucky. DISCUSSION...A tornado threat is likely to develop later this evening as a broken line of supercells moves into the region. These supercells have a history of confirmed tornadoes. The overall environment across northern Kentucky is marginally to moderately unstable, with MUCAPE ranging from just under 1000 J/kg to around 1500 J/kg. Continued low-level theta-e advection to the southeast of a MCV across central Indiana should sustain or slightly increase instability despite the loss of diurnal heating. Additionally, a favorable kinematic environment (Louisville VAD showing 0-3 kilometer SRH increasing the last hour to nearly 500 m2/s2) will remain into the late evening hours. Thus, as the upstream supercells move into the region, the threat for tornadoes will persist. A new tornado watch will likely be needed within the hour. ..Marsh/Smith.. 06/22/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...JKL...ILN...LMK...

MD 1237 CONCERNING TORNADO WATCH 363...365... FOR SOUTHERN ILLINOIS INTO SOUTHERN AND CENTRAL INDIANA
Mesoscale Discussion 1237 NWS Storm Prediction Center Norman OK 0653 PM CDT Sun Jun 21 2026 Areas affected...southern Illinois into southern and central Indiana Concerning...Tornado Watch 363...365... Valid 212353Z - 220130Z The severe weather threat for Tornado Watch 363, 365 continues. SUMMARY...The tornado threat continues across Tornado Watches #363 and #365. DISCUSSION...Supercells with a history of producing tornadoes are ongoing across Tornado Watches #363 and #365 this evening. The overall environment remains very favorable for thunderstorm rotation, with effective-layer shear on the order of 40-50 knots and 0-3 kilometer SRH ranging from 400 m2/s2 from the Evansville, IN, VAD to over 600 m2/s2 from the Indianapolis, IN, VAD. Likely contributing to this enhanced low-level helicity is a strong easterly component to the low-level wind field in response to an MCV tracking northeast into central Indiana. As this MCV moves northeast toward Indianapolis, increasing low-level theta-e to the south and east of the MCV should be sufficient to offset the loss of diurnal heating to maintain sufficient instability into the evening hours, particularly across the watch area. Thus, the threat for thunderstorms will continue. The threat for tornadoes will exist as long as ongoing thunderstorms can remain sufficiently rooted in the boundary layer to ingest these helicity-rich low-level air parcels. As storms move east of I65, low-level theta-e quickly drops off and storms should become increasingly elevated. As this occurs, the overall tornado threat should lessen and a transition to strong, damaging winds may occur before thunderstorms weaken. ..Marsh.. 06/21/2026 ...Please see www.spc.noaa.gov for graphic product...

MD 1238 CONCERNING SEVERE THUNDERSTORM WATCH 364... FOR PORTIONS OF WESTERN NEBRASKA
Mesoscale Discussion 1238 NWS Storm Prediction Center Norman OK 0655 PM CDT Sun Jun 21 2026 Areas affected...portions of western Nebraska Concerning...Severe Thunderstorm Watch 364... Valid 212355Z - 220130Z The severe weather threat for Severe Thunderstorm Watch 364 continues. SUMMARY...A few instances of severe hail and perhaps a severe gust remain possible with the stronger storms over the next few hours. DISCUSSION...MRMS mosaic radar imagery has shown an uptick in convective intensity with multicells across western NE over the past 1-2 hours. These storms are approaching an airmass characterized by 1500+ J/kg MLCAPE and 50 kts of effective bulk shear, which will continue to support a severe hail threat. A severe gust is also possible given the 8-9 C/km low-level lapse rates in place (per 23Z mesoanalysis). Nonetheless, the ongoing storms are approaching an area of increasing convective inhibition due to tropospheric overturning caused by earlier storms. It is unclear how long-lived the longer-term severe threat will be in NE given convective overturning. However, in the near term, a few instances of severe hail or a gust remain possible. ..Squitieri.. 06/21/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LBF...

MD 1236 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR NORTHWEST OKLAHOMA
Mesoscale Discussion 1236 NWS Storm Prediction Center Norman OK 0612 PM CDT Sun Jun 21 2026 Areas affected...northwest Oklahoma Concerning...Severe potential...Watch possible Valid 212312Z - 220115Z Probability of Watch Issuance...40 percent SUMMARY...Thunderstorms may develop across the area this evening. Should they develop, the overall environment will support large hail and damaging winds and a watch would become necessary. The area will be monitored closely for thunderstorm potential and subsequent need for a watch. DISCUSSION...A remnant outflow boundary is located across northern Oklahoma, stretching from near Woodward, OK, east toward Ponca City, OK. The cumulus field along this boundary has become increasingly agitated over the last hour, with clumping of the cumulus across Woodward County, OK, noted. Thunderstorm development is uncertain this afternoon, with the high-resolution numerical guidance oscillating back and forth between solutions with initiation and solutions without initiation. (The most recent runs of the HRRR -- 21 & 22 UTC -- do initiate this evening across northwest Oklahoma.) Should storms develop, the overall thermodynamic environment across the area is very unstable with MUCAPE values between 3000-4000 J/kg, with forecast soundings suggesting the maximum lapse rates in the 2-6 kilometer layer achieving 8 C/km. Kinematically, the environment is strongly sheared, with effective-layer shear around 40 knots. Given this environment, an evolution toward supercells would be possible with any thunderstorm. Relatively straight hodographs would suggest that splitting supercells would be possible, with large hail and damaging winds possible (RAP profiles suggest DCAPE ~1500 J/kg). Low-level flow is relatively weak across the area, so the overall tornado threat should be somewhat limited. However, with the potential for supercellular mode, strong instability, and a surface boundary, the tornado potential is non-negligible. Should confidence increase that initiation is underway or imminent, a watch may become necessary across portions of northwest Oklahoma. Regardless of whether thunderstorms initiate this afternoon/evening, a more appreciable threat for severe thunderstorms is likely to evolve later tonight with a southeast-advancing MCS moving into the region from Kansas. ..Marsh/Smith.. 06/21/2026 ...Please see www.spc.noaa.gov for graphic product...
