Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0758 PM CDT Sat May 30 2026 Valid 310100Z - 311200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE BLACK HILLS INTO PARTS OF THE CENTRAL PLAINS... ...SUMMARY... Severe thunderstorm potential will continue this evening and parts of the overnight, mainly within the central Plains. ...Synopsis... An arcing zone of convection is ongoing across parts of Nebraska into central Kansas. The strongest forcing for ascent will be present in Nebraska as the shortwave trough pivots north through the evening. This activity will still be capable of large hail, severe winds, and a couple of tornadoes as the low-level jet modestly strengthens into the evening. Additional storms will continue in central Kansas. The 00Z observed TOP sounding showed steep mid-level lapse rates, but some capping at low levels. While activity will tend to become elevated into the evening, strong to severe/damaging winds will remain possible farther east. Large hail potential will be somewhat mitigated be less favorable storm modes. Within the southern Plains, an isolated storm is possible on the dryline in the next couple of hours, but confidence in this scenario is low as forcing for ascent is weak and low-level stability will increase with time. ..Wendt.. 05/31/2026 Read more

MD 0910 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF THE EDWARDS PLATEAU OF SOUTHERN TEXAS
Mesoscale Discussion 0910 NWS Storm Prediction Center Norman OK 0531 PM CDT Sat May 30 2026 Areas affected...Portions of the Edwards Plateau of southern Texas Concerning...Severe potential...Watch unlikely Valid 302231Z - 310030Z Probability of Watch Issuance...20 percent SUMMARY...Thunderstorm development across the Big Bend/Edwards Plateau region may be very isolated, but the downstream environment may support intense convection through late evening. Watch issuance is currently not expected given limited storm coverage. DISCUSSION...Convection has been percolating along a dryline across the Big Bend/Edwards Plateau over the past couple of hours. Although deep initiation has struggled to remain sustained, lightning trends within a couple of deeper convective cores east/southeast of Fort Stockton, TX have increased over the past 20 minutes, hinting at a higher potential for sustained convection. If mature thunderstorms can be established, they will quickly migrate into an environment very favorable for intense convection (MLCAPE of 2000-3000 J/kg with elongated hodographs featuring 45 knots of effective bulk shear). Within this environment, splitting supercells appear probable and will pose a threat for large to very large hail as well as severe gusts. Given weak synoptic-scale forcing for ascent, it remains to be seen whether these more recent attempts at sustained convection will succeed or whether storm coverage will be more than a storm or two. Because of these concerns watch issuance is currently not anticipated, but trends will be monitored. ..Moore/Guyer.. 05/30/2026 ...Please see www.spc.noaa.gov for graphic product...

MD 0911 CONCERNING SEVERE THUNDERSTORM WATCH 252... FOR PARTS OF WESTERN NEBRASKA AND SOUTH DAKOTA...NORTHEAST COLORADO...AND EXTREME EASTERN WYOMING
Mesoscale Discussion 0911 NWS Storm Prediction Center Norman OK 0620 PM CDT Sat May 30 2026 Areas affected...parts of western Nebraska and South Dakota...northeast Colorado...and extreme eastern Wyoming Concerning...Severe Thunderstorm Watch 252... Valid 302320Z - 310045Z The severe weather threat for Severe Thunderstorm Watch 252 continues. SUMMARY...Thunderstorms will continue to develop this evening across Severe Thunderstorm Watch #252. Isolated large hail and strong winds will remain possible across the watch. DISCUSSION...Thunderstorms continue to develop and grow upscale into north-south linear clusters this afternoon/evening to the northeast of a negatively tilted mid-level trough moving across north-central Colorado into eastern Wyoming. The overall environment remains favorable for strong to severe thunderstorms, with MUCAPE in the 1000-2000 J/kg range, with deep-layer shear on the order of 30 knots. However, deep-layer shear is mostly parallel to the initiating boundaries, which will favor seeding of downstream updrafts, acting as an overall check on thunderstorm intensity. Thus, despite overall an environment that would support a sustained hail and wind threat this evening, the most likely scenario is for any severe hail or wind to occur on an isolated basis with the strongest of updraft cores as the overall complex moves east into the central/northern Plains. The activity should weaken later this evening with the loss of diurnal heating. ..Marsh.. 05/30/2026 ...Please see www.spc.noaa.gov for graphic product...

MD 0909 CONCERNING SEVERE THUNDERSTORM WATCH 253... FOR CENTRAL KANSAS
Mesoscale Discussion 0909 NWS Storm Prediction Center Norman OK 0458 PM CDT Sat May 30 2026 Areas affected...Central Kansas Concerning...Severe Thunderstorm Watch 253... Valid 302158Z - 310000Z The severe weather threat for Severe Thunderstorm Watch 253 continues. SUMMARY...The severe threat will likely increase across central Kansas over the next few hours as thunderstorms migrate into a corridor of extreme buoyancy. DISCUSSION...Two clusters of multicells and embedded supercells have emerged south of Hays, KS and to the west of the Wichita, KS area. Regional velocity imagery shows the early development of mid-level mesocyclones with a few of these cells, hinting that deep-layer shear is likely adequate to support supercells. Nearby VWP observations from KICT have sampled 0-6 km BWD values near 35 knots, which is stronger than estimated by recent RAP mesoanalyses. Additionally, these VWP observations are depicting 0-3 km SRH on the order of 300 m2/s2 to the north of a subtle outflow boundary, which will further support the potential for supercells, and perhaps a locally higher tornado threat, over the next few hours as convection begins to interact with this boundary. Similarly, a subtle outflow boundary is noted further north downstream of the cluster near Hays, KS. Enhanced low-level vorticity in proximity and north of this boundary may promote better storm organization and a localized tornado threat. However, any tornado potential will be conditional on maintaining at least semi-discrete storm modes. Based on recent radar trends, it remains to be seen whether these clusters will become primarily outflow dominant - which will likely diminish the tornado potential. Whether or not convection will become outflow dominant should become apparent over the next hour or so. Regardless, both clusters are migrating into the regional buoyancy maximum where MLCAPE values are estimated to be near 4000 J/kg. This will promote further intensification of ongoing convection, especially the potential for severe wind gusts. ..Moore.. 05/30/2026 ...Please see www.spc.noaa.gov for graphic product...
