MD 0917 CONCERNING SEVERE THUNDERSTORM WATCH 253... FOR CENTRAL AND NORTHEAST KANSAS INTO ADJACENT PORTIONS OF NEBRASKA AND FAR WESTERN MISSOURI Mesoscale Discussion 0917 NWS Storm Prediction Center Norman OK 0925 PM CDT Sat May 30 2026 Areas affected...Central and northeast Kansas into adjacent portions of Nebraska and far western Missouri Concerning...Severe Thunderstorm Watch 253... Valid 310225Z - 310430Z The severe weather threat for Severe Thunderstorm Watch 253 continues. SUMMARY...The potential for severe hail and wind should continue into the late evening hours. However, this threat should become more isolated with time. DISCUSSION...Pockets of strong/severe thunderstorms continue across portions of central/northeast KS and south-central NE. A persistent convective cluster northeast of the Wichita, KS area has maintained intensity over the past hour despite the onset of nocturnal cooling - likely owing to increasing ascent on the southern flank of the convective cold pool related to the recent onset of the nocturnal jet. Similarly, new convective cores are noted across central KS over the cold pool. Weak deep-layer wind shear should limit longevity of these cores, but given residual buoyancy and increasing isentropic ascent, some hail threat may linger as stronger cores briefly pulse to severe limits. Further northeast, pockets of strong winds remain evident in regional velocity imagery across south-central NE and northeast KS. Additionally, new cell development is noted in the Topeka, KS vicinity, though cell longevity has been limited - likely due to similarly modest deep-layer wind shear. Mid-level flow generally weakens with northeastward extent, which limits confidence in the potential for a more prolonged/robust severe threat. Consequently, downstream watch issuance appears unlikely at this point. However, a localized hail/wind threat should persist for the next several hours. ..Moore.. 05/31/2026 ...Please see www.spc.noaa.gov for graphic product...
