   Areas affected...Parts of the middle/upper Texas Coast

   Concerning...Severe potential...Watch unlikely 

   Valid 281902Z - 282030Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Locally damaging gusts and/or a brief tornado could
   accompany storms near the middle/upper Texas coast this afternoon.

   DISCUSSION...A small storm cluster has evolved early this afternoon
   near the middle TX coast, immediately in advance of a midlevel
   vorticity maximum embedded within a larger mid/upper trough over
   central/south TX. Modest diurnal heating has allowed MLCAPE to rise
   near 1000 J/kg downstream of this cluster, with some development of
   deep convection also noted closer to Galveston Bay. 

   While flow in the lowest 3 km has weakened somewhat compared to this
   morning (as noted on the KHGX VWP), modestly favorable low-level
   shear/SRH remains in place across the region. The ongoing storm
   cluster earlier produced a 55 mph gust, and strong to isolated
   severe gusts will remain possible through the afternoon before this
   cluster moves offshore, and a brief tornado also cannot be ruled
   out.
