Valid 280654Z - 280800Z The severe weather threat for Tornado Watch 154, 155 continues. SUMMARY...Greatest severe potential is expected across southwest Missouri in the short term. Overall risk is diminishing with northward extent. DISCUSSION...Outflow associated with convection across central MO into west-central IL is outpacing convection over the past hour or two. This, coupled with increasing low-level inhibition/boundary-layer stabilization is largely limiting severe potential. As a result, Tornado Watch 154 will be cancelled early per collaboration with WFO LSX. Further southwest, a more mature/organized QLCS over northeast OK will spread into southwest MO. While weak low-level inhibition is present, stronger ascent and more favorable low-level shear may still support a tornado and damaging wind risk over the next couple of hours, especially across southern portions of Tornado Watch 155. ..Leitman.. 04/28/2024 ...Please see www.spc.noaa.gov for graphic product...
