Broadly cyclonic flow aloft will remain over the CONUS today, with
prevalent surface high pressure across the Plains/Midwest and a
prominent front across the Deep South. Elevated thunderstorm
potential across the Mid-South will continue to diminish into
midday/early afternoon as warm-air advection abates. Thunderstorms
may also develop across downstate parts of the Carolinas this
afternoon into evening near the aforementioned front and a weak
surface wave. Modest surface-based instability will exist mainly
across coastal South Carolina in the presence
semi-straight/elongated hodographs, but modest convergence and
residual warm layers aloft are suggestive of a minimal
severe-weather potential.
