   The severe weather threat for Tornado Watch 27 continues.

   SUMMARY...Frontal, and prefrontal convection is expected to
   gradually increase over the next few hours.

   DISCUSSION...Surface front is surging southeast across IL and
   currently arcs from near DNV-SAR. Over the last hour or so,
   convection has gradually increased along/ahead of the immediate wind
   shift, especially west-southwest of HUF to Effingham. Lightning is
   increasing with this activity, and trailing midlevel convection
   across central IL suggests large-scale ascent is overspreading this
   region. Given these trends, convection may continue to increase near
   the front as it surges toward southwest IN.
