   ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE WESTERN
   NORTH TEXAS VICINITY...

   ...SUMMARY...
   Scattered strong/isolated severe storms will be possible today from
   parts of the Upper Midwest to the southern Plains.

   ...Synopsis...
   Broad west-southwesterly flow aloft is forecast from the southwest
   to the Great Lakes, south and east of a low moving
   east-northeastward in the vicinity of the U.S./Canadian border.  As
   this occurs, a weak cold front will cross the central U.S., reaching
   a position from the Upper Great Lakes to central Texas by the end of
   the period.

   ...Western North Texas vicinity...
   Ongoing/weakening convection should be crossing eastern
   Oklahoma/north Texas at the start of the period, with some
   ramifications for subsequent destabilization potential ahead of the
   advancing cold front -- particularly across Oklahoma.

   With that said, ample destabilization is forecast to occur from the
   southwestern Oklahoma/western North Texas region southward, to
   support new convective initiation by late afternoon.  A
   likely/favored location for initial updrafts will likely be near the
   cold front/dryline intersection, forecast in the vicinity of
   southwestern Oklahoma/eastern portions of the Texas South Plains/the
   Big Country region.  Initial/cellular convection will pose a risk
   for very large hail, along with locally damaging gusts and possibly
   a tornado or two, though limited to some degree by rather modest
   shear.

   With time, upscale growth may occur, with some models hinting that a
   bowing MCS may shift eastward across North Texas through the
   evening.  Some eastward expansion of the SLGT risk area is being
   included in light of this model signal, though the aforementioned
   lack of more robust flow suggests severe risk will remain somewhat
   isolated.

   ...Upper Midwest/southern Upper Great Lakes to eastern Kansas...
   A weakening band of convection is forecast to be crossing
   Iowa/northwestern Missouri/eastern Kansas at the start of the
   period, in advance of the surface cold front.  Sporadic gusty winds
   and marginal hail may occur with a couple of the lingering/stronger
   storms.  Later, weak heating/modest destabilization within the warm
   sector should support renewed convection near the advancing front
   during the afternoon.  With stronger flow confined to the cool side
   of the front, and limited instability, any occurrences of wind
   and/or hail reaching severe levels should remain largely isolated,
   with risk diminishing by evening.

   ...Southeastern Texas/southwestern Louisiana...
   Indications are that an organized/potentially bowing MCS may be
   moving east-southeastward across southeastern Texas at the start of
   the period.  Prior to moving offshore, strong/locally severe wind
   gusts will be possible during the first couple of hours of the
   period.
