ACUS11 KWNS 190155 SWOMCD SPC MCD 190154 IAZ000-MOZ000-KSZ000-190500- Mesoscale Discussion 0780 NWS Storm Prediction Center Norman OK 0854 PM CDT Mon May 18 2026 Areas affected...eastern Kansas...northwest Missouri...southern Iowa Concerning...Tornado Watch 225...227... Valid 190154Z - 190500Z The severe weather threat for Tornado Watch 225, 227 continues. SUMMARY...Severe winds are likely along the length of an extensive squall line extending from central Iowa across western Missouri and into south-central/eastern Kansas. Isolated/brief tornadoes may still occur from eastern Kansas into western Missouri. DISCUSSION...Storms have largely consolidated into a squall line this evening, with various bowing segments with the line. One such segment is evident over northeast KS, with another moving across northern MO. The nearly north-south orientation of these segments is more favorable for significant wind damage as the leading outflow remains in balance/closer to the storms. The most favorable combination of low-level shear and instability currently extends from eastern KS into western MO, just ahead of the squall line and beneath the 55 kt low-level jet. The EAX VWP indicates 300 m2/s2 0-1 km SRH which may support periodic QLCS tornado potential. Farther southwest into south-central KS, echoes are training slowly, with robust cores producing hail at times. Measured severe gusts over 50 kt have occurred here as well, and these storms should maintain strength as the low-level jet persists directly in from the south. ..Jewell.. 05/19/2026 ...Please see www.spc.noaa.gov for graphic product...
