   Areas affected...North Central TX

   Concerning...Tornado Watch 178...

   Valid 290228Z - 290430Z

   The severe weather threat for Tornado Watch 178 continues.

   SUMMARY...Supercells capable of very large hail will continue to
   track southeastward.

   DISCUSSION...Two intense supercells continue to affect parts of
   north-central TX, over Hill/Bosque/Limestone counties.  This cluster
   of storms has a long history of significant hail damage during the
   past few hours.  CAPE values remain very high, with steep lapse
   rates and strong deep layer shear indicated on the 00z FWD sounding.
    However, cap strength is increasing as the boundary layer slowly
   cools.  This is likely to lead to some weakening over the next
   couple of hours.  Nevertheless, some severe risk will likely persist
   until at least midnight.
