   Areas affected...Western Oklahoma...Northwest Texas Including the
   Eastern Panhandle...North-Central Texas

   Concerning...Severe Thunderstorm Watch 160...

   Valid 072317Z - 080115Z

   The severe weather threat for Severe Thunderstorm Watch 160
   continues.

   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
   unlikely.
