   Areas affected...northeast Texas/northwestern Louisiana

   Concerning...Tornado Watch 146...

   Valid 250226Z - 250400Z

   The severe weather threat for Tornado Watch 146 continues.

   SUMMARY...Severe risk -- including potential for destructive winds
   and very large hail -- continues across parts of northeast Texas and
   adjacent northwestern Louisiana.

   DISCUSSION...Latest radar loop shows several supercell storms over
   the northwestern Louisiana vicinity, with one large cell crossing
   the Cass/Marion County Texas and Caddo County Louisiana border area
   suggestive of destructive wind gust potential, along with very large
   hail.  Inbound velocities per the KSHV WSR-88D in the RFD region of
   this cell are in the 60 to 70 kt range at roughly 1500 feet AGL, and
   so wind gusts well in excess of 60 MPH are expected.

   With time, expect continued evolution toward damaging wind potential
   -- including a possible bow echo evolution -- as storms move across
   northwestern Louisiana and eventually into WW 147.
