Areas affected...Dallas/Fort Worth Metroplex

Concerning...Severe potential...Watch unlikely

Valid 250805Z - 251000Z

Probability of Watch Issuance...20 percent

SUMMARY...An isolated large hail and wind-damage threat may persist
for another hour or two as a small complex of storms moves into the
Dallas/Fort Worth Metroplex. The severe threat area is expected to
remain small, and watch issuance is not expected.

DISCUSSION...The latest high-resolution radar imagery shows a small
cluster of strong to severe storms located just to the north of the
Dallas/Fort Worth Metroplex. RAP analysis suggests that the airmass
is moderately unstable with MLCAPE around 1000 J/kg. The latest
WSR-88D VWP from Fort Worth has 0-6 km shear near 45 knots, with
gradually veering winds in the low to mid-levels. In addition, RAP
forecast soundings have steep mid-level lapse rates around 700 mb.
This should be enough to continue an isolated large-hail threat with
transient supercell structures embedded in the cluster. An isolated
wind-damage threat may also accompany the leading edge of the more
intense cells. The threats are expected to continue for another hour
or two.
