Concerning...Tornado Watch 27...

Valid 280550Z - 280715Z

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.
