Scattered to numerous severe storms with swaths of wind damage, very large hail, and a couple brief tornadoes remain possible through late evening across southeast Oklahoma into western Arkansas and north/northeast Texas. More isolated strong to severe storms remain possible this evening across the interior Pacific Northwest. ...Southeast Oklahoma into northeast Texas... A cluster of supercells have started to congeal across southern Oklahoma. These supercells have a history of producing very large hail, but may be transitioning into a greater severe wind threat as they move into north Texas this evening. These storms may persist into the overnight hours as the airmass ahead of them remains very unstable and moderately sheared per 00Z KFWD RAOB. Please see MCD 778 for additional details. ...Ohio Valley... A few strong to marginally severe storms may persist through the overnight hours across the Ohio Valley ahead of a cold front. ...Lower Mississippi Valley... A line of storms will continue southeast across Mississippi this evening. These storms will have the potential to be severe for another hour or two before the threat wanes by the late evening as inhibition increases and storms outrun the better deep-layer shear. ..Bentley.. 05/16/2022 Read more CHECK UPDATE ZOOM GRAPHIC
