...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE
SOUTHERN HIGH PLAINS...

...SUMMARY...
Some strong to locally severe thunderstorms may occur late this
afternoon and evening across the southern High Plains.

...Southern High Plains...
A belt of moderate-strength west-northwesterly flow aloft will
persist atop a moist airmass regionally. Post-MCS air mass
influences and lingering cloud cover/outflows may be factors into
the afternoon, but RAP/HRRR-related guidance has trended a bit more
unstable and potentially more conducive to some isolated severe
storms later today. While confidence in forecast details are not
particularly high, this potential appears to be mainly focused in a
corridor across northeast New Mexico into the Texas Panhandle/Texas
South Plains, and possibly western Oklahoma later this afternoon
into evening. This is where locally moderate destabilization may
occur coincident with effective shear magnitudes that may reach
30-40 kt, with storm development focused near the surface trough
and/or influenced by differential heating. A few instances of severe
hail and/or wind will be possible.
