The severe weather threat for Severe Thunderstorm Watch 160
SUMMARY...Threat for severe weather in northern portions of WW 160
have decreased. Strong to severe storms in southern area of WW 160
will continue to pose a severe wind gust and isolated hail threat
for the next few hours. Convective trends are being monitored for
possible downstream WW issuance in parts of north-central Texas.
DISCUSSION...Strong to severe storms have persisted in the southern
portions of WW 160 and have been slowly progressing to the south. A
few instances of 1 inch hail and severe wind gusts have been
reported with these storms within the last hour. How much
development occurs to the east of this complex is uncertain given
the outflow in that area.
To the south of WW 160, temperatures remain in the mid-90s and
above, continued progression of ongoing storms is possible. However,
with time, these storms will likely become increasingly elevated and
move into less favorable deep-layer shear. Given analyzed MUCAPE
values of 1500-2000 J/kg, isolated severe wind gusts and hail will
remain possible with the strongest storms. Areas south of WW 160
will continue to be monitored for possible WW issuance.
Farther to the north, anvil material from the storm complex has led
to boundary layer stabilization. Redevelopment in this region is
