   Concerning...Severe Thunderstorm Watch 319...

   Valid 260005Z - 260100Z

   The severe weather threat for Severe Thunderstorm Watch 319
   continues.

   SUMMARY...Thunderstorms will continue to develop northeastward out
   of central Illinois into northwest Indiana this evening. Marginally
   severe hail, gusty winds, and a brief tornado will be possible.

   DISCUSSION...Thunderstorms are expected to continue developing
   northeastward this evening. Surface dewpoints in the low 70s and
   temperatures in the low 80s will maintain most-unstable CAPE values
   up to 1000 J/kg. This should be maintained into the evening as the
   low-level jet develops this evening and maintains low-level theta-e.
   This should support at least a marginally severe hail threat and
   potential for strong thunderstorm outflow. Additionally, a myriad of
   outflow boundaries from earlier convection remain across the area.
   Any thunderstorm updraft that latches onto one of these boundaries
   may result in a brief tornado.
