Areas affected...central into northeast Illinois into far northwest
Indiana.

Concerning...Tornado Watch 313...

Valid 112314Z - 120045Z

The severe weather threat for Tornado Watch 313 continues.

SUMMARY...The tornado threat continues across watch 313 with an
increasing damaging wind threat this evening.

DISCUSSION...A broken line of storms has intensified along the front
within the past hour. Expect this line to continue to intensify
through the evening as the environment ahead of it continues to
destabilize. The greatest threat for strong to intense tornadoes
will likely be with the more discrete storms ahead of the line and
within the break across north-central Illinois for the next 1 to 2
hours. By later this evening, the damaging wind threat will become
more pronounced as this line of storms matures and expands and
eventually overtakes the discrete storms. Some QLCS and embedded
supercell tornado threat will exist within the line during the late
evening, but tornado intensity should be less by that time.
