   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF
   THE TEXAS COASTAL BEND...

   ...SUMMARY...
   A couple of strong to severe thunderstorms are possible across
   portions of the Lower and Middle Texas Coast vicinity this
   afternoon. Locally strong wind gusts, marginally severe hail, or a
   brief tornado may occur with the strongest storms.

   ...Synopsis...
   A weakening mid-level trough will meander across Texas through the
   day as a more pronounced upper trough amplifies across the northern
   CONUS, with cool and stable surface conditions emanating from the
   northern Rockies and overspreading much of the central U.S. Across
   central Texas, scattered thunderstorms will be ongoing at the start
   of the period in advance of the decaying mid-level trough. However,
   ascent with the aforementioned trough will gradually overspread a
   moister air mass closer to the Gulf in portions of southern Texas.
   Thunderstorms are expected to increase in number and intensity into
   the afternoon, with a couple strong to potentially severe storms
   possible.

   ...Portions of southeast Texas...
   Elevated convection is expected to be ongoing at 12Z across central
   TX as the aforementioned trough slowly encounters slightly deeper,
   richer moisture impinging on the shoreline from the Gulf of Mexico.
   While surface temperatures/dewpoints are expected to be modest by
   afternoon (i.e. barely exceeding 60 F), rain-cooled air from initial
   elevated storms is expected to reinforce a weak baroclinic zone
   extending across portions of the TX Coastal Bend. On the immediate
   warm side of the boundary, mediocre surface-based buoyancy may
   materialize amid poor lapse rates as cool mid-level temperatures
   overspread the 58-60F surface dewpoints. As such, the elevated
   convection is expected to grow upscale while also attempting to
   become surface-based, with the development of an MCS and apparent
   MCV likely based on the latest high-resolution guidance consensus.
   While deep-layer shear should be modest overall, locally higher
   values of 0-3 km effective SRH may accompany the baroclinic zone.
   Embedded rotating storms capable of producing a couple damaging
   gusts and perhaps an instance of marginally severe hail/a brief
   tornado may materialize should storms become surface based,
   warranting the maintenance of the Category 1/Marginal risk.
