Areas affected...northeast New Mexico into the Texas Panhandle and
surrounding areas

Concerning...Severe Thunderstorm Watch 336...

Valid 092341Z - 100145Z

The severe weather threat for Severe Thunderstorm Watch 336
continues.

SUMMARY...The threat for severe hail and wind continues, and may
spread southeastward across parts of northwest Texas and far
southwest Oklahoma. An additional watch may be required.

DISCUSSION...An axis of stronger MLCAPE currently stretched from
northern TX and southern OK into western OK and the eastern
Panhandles, with values over 3000 J/kg. Scattered storms persist
within the surface trough from northeast NM into the TX/OK
Panhandles, beneath modest northwest flow aloft.=20

Given the uncapped air mass downstream, outflow now being created
over the area may serve as a focus for an MCS this evening. The
initial cells may produce hail, but the primary concern may
eventually be damaging wind gusts as a possible complex develops. As
such, a new watch may be needed for parts of the TX Panhandle into
northwest TX and southwest OK.

Areas affected...Central/Southern AR

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

Valid 161657Z - 161900Z

Probability of Watch Issuance...40 percent

SUMMARY...Ongoing thunderstorm cluster may strengthen as it moves
southeastward into more of central AR, with an attendant threat for
damaging gusts and large hail. Convective trends will be monitored
for potential watch issuance.

DISCUSSION...Thunderstorm cluster in the FSM vicinity has trended
towards more forward propagation over the past hour or so. The
warm-air advection helping to support this elevated cluster is
forecast to continue weakening over the next few hours. Given that
this cluster is north of the stronger buoyancy, there is some
uncertainty regarding how this weakening will impact the ongoing
cluster. That being said, the downstream airmass is destabilizing
amid a combination of low-level moisture recovery and daytime
heating. Additionally, this cluster is on the leading edge of a
shortwave trough and associated speed max rounding the ridge
extending up through the southern High Plains. As a result, despite
weakening low-level flow, the combination of large-scale lift and
downstream destabilization is expected to support the persistence,
and perhaps intensification, of this cluster. If intensification is
realized, a threat for damaging gusts and isolated large hail may
exist over central and southern AR this afternoon. Convective trends
will be monitored for potential watch issuance.
