Concerning...Tornado Watch 184...

The severe weather threat for Tornado Watch 184 continues.

SUMMARY...Isolated supercells, posing all-hazards severe risk, are
ongoing in/near Tornado Watch 184. Later, upscale growth/expansion
of storms is expected, which is likely to eventually require
new/downstream WW issuance.

DISCUSSION...Latest KMAF radar loop shows a persistent supercell
moving southeastward across Pecos county, which has produced
previous tornadoes and currently appears likely to be producing very
large hail. A second supercell which has developed more recently is
moving along the Midland/Upton County border, and also poses an
all-hazards risk in the short term.

Meanwhile, convection is increasing in coverage farther east,
including a longer-lived storm now over northern portions of Coleman
and Brown counties. With time, CAMs suggest upscale growth emerging
from within the broader area of storms, and shifting eastward as an
at least semi-organized MCS. This seems plausible, given a fairly
well-defined vort max aloft moving across southeastern New Mexico
and Far West Texas, and an associated increase in a southeasterly
low-level jet expected to occur this evening. Resulting QG ascent,
combined with the favorably moist/unstable environment downstream,
should act to sustain convection and associated expansion of severe
risk east of the existing WW. A new WW will likely need to be
considered -- perhaps earlier than optimal due to the proximity of
the convective increase in the Coleman/Brown county area and
vicinity to the eastern edges of WW 183 and 184.
