Concerning...Severe potential...Watch possible=20

Valid 132040Z - 132245Z

Probability of Watch Issuance...40 percent

SUMMARY...Several outflow-dominant thunderstorm clusters may develop
across the region this afternoon/evening. Damaging gusts are the
primary risk with this activity.

DISCUSSION...Cumulus continues to build across the high terrain from
southern CO through central NM, with a few instances of lightning
observed as well. Despite large-scale ridging, thunderstorm coverage
is expected to gradually increase amid persistent southwesterly flow
aloft and related weak ascent. The airmass downstream across the
southern High Plains is deeply mixed, with LCLs from 10 to 12 kft,
and only weakly buoyant. As such, the expectation is for storms to
quickly become outflow-dominant when the move off the terrain over
the next few hours. Outflow interactions could lead to one or more forward-propagating clusters, any of which could produce strong to
severe wind gusts. Severe coverage will likely remain isolated, and
the need for a watch is uncertain. Overall convective trends will be
monitored closely.

Farther east across western portions of the TX South Plains, an area
of deepening cumulus has been noted. Convective inhibition has
largely eroded in this area, and there is some chance an isolated
storm develops. However, given the significant dry air present,
there is a low-probability for sustained deep convection in the
near-term.
