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

....SUMMARY...
Marginally severe thunderstorms, associated with isolated large hail
and a few severe wind gusts, will be possible Friday night in parts
of the southern High Plains.

....Southern High Plains...
Southwesterly mid-level flow will be in place across the Rockies and
Great Plains on Friday, as a trough moves inland across the West
Coast. Moisture advection will take place over the southern and
central Plains, with surface dewpoints likely reaching the 60s F
across much of Texas. The strongest instability is forecast by mid
to late evening from far West Texas into eastern New Mexico, where
scattered thunderstorms appear likely to develop. Additional
convection is expected further to the east across west-central
Texas. During the overnight period, thunderstorm coverage is
forecast to expand northeastward into parts of the Texas Panhandle
and northwest Texas. Forecast soundings from far West Texas into the
Texas Panhandle Friday evening and overnight have MLCAPE reaching
the 1000 to 1500 J/kg range. 0-6 km shear is forecast to be in the
30 to 35 knot range, with 700-500 mb lapse rates around 6.5 C/km.
This environment would be sufficient for supercells with large hail.
Marginally severe wind gusts will also be possible. The severe
threat could persist to late in the period.
