Scattered thunderstorms with marginally severe wind gusts and hail, will be possible on Tuesday across parts of the southern Plains. ...Southern Plains... An ill-defined shortwave trough is forecast to move eastward into the southern Plain on Tuesday. At the surface, a moist airmass is forecast across much Texas and Oklahoma. As surface temperatures warm during the day, scattered thunderstorms are expected to form across parts of this moist airmass. Thunderstorm development will be most likely along residual outflow boundaries, and in areas where instability becomes locally maximized. Although the models are not focused on any particular area across the southern Plains, there is agreement that at least one or two convective clusters could develop and persist for several hours during the afternoon and evening. Across most of the moist airmass, moderate instability is expected to be in place by afternoon. Although low to mid-level flow will be somewhat weak, winds are forecast to veer with height over much of the region. This directional shear could be enough for a marginal severe threat. Hail and strong wind gusts will be the primary threats during the late afternoon and early evening, as instability maximizes. A convective cluster, associated with a localized severe threat, could persist into the mid to late evening. ..Broyles.. 06/09/2024 $$
