   Areas affected...Parts of east Texas into northwestern Louisiana

   Concerning...Tornado Watch 53...

   Valid 131652Z - 131815Z

   The severe weather threat for Tornado Watch 53 continues.

   SUMMARY...The risk for tornadoes, a couple possibly strong, will
   continue to gradually increase through 1-3 PM CDT, while potentially
   damaging winds may also increase along an eastward advancing gust
   front.

   DISCUSSION...16Z surface observations indicate strongest 2 hourly
   surface falls (4-5 mb) focused in an area near/southeast of Tyler TX
   into the Shreveport and Fort Polk LA vicinities.  This is also
   roughly along/west of the southerly 850 mb jet axis, which is
   forecast to strengthen to 40-50+ kt through 18-20Z.  Associated
   enlargement of low-level hodographs, coupled with boundary layer
   warming and moistening associated with the northward advancement of
   the surface warm front, may result in increasing tornadic potential
   in evolving discrete supercell storms across this region through mid
   afternoon.

   At the same time, an upscale growing and organizing mesoscale
   convective system appears to be accelerating eastward, across and
   east of the Interstate 35 corridor, and may approach parts of the
   Ark-La-Tex region by 20Z, with a gust front accompanied by potential
   to produce damaging winds.
