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

...SUMMARY...
Isolated severe thunderstorms are possible across portions of the
central and southern High Plains on Wednesday.

...Central/Southern High Plains...

A persistent low-amplitude, weak southwesterly flow pattern will
persist across the Plains and into the eastern U.S. on Day
3/Wednesday. Forecast guidance indicates some weak shortwave
perturbations will migrate through this weak southwesterly flow
aloft, emanating from a weak upper trough over the western U.S. At
the surface, southerly low-level flow will continue to transport
modified Gulf moisture northward across the southern Plains and into
the central Plains. A stalled frontal boundary will extend from
southern MN into central NE and northeast CO, while a dryline
extends southward across the central/southern High Plains.
Persistent moist advection will allow for weak to moderate
destabilization within the vicinity of the aforementioned surface
boundaries, and isolated to widely scattered thunderstorm
development will be possible by late afternoon/evening. Large hail
and strong gusts could accompany this activity from southwest NE
into western TX.
