Areas affected...central into north-central Indiana

Concerning...Tornado Watch 318...

Valid 120119Z - 120245Z

The severe weather threat for Tornado Watch 318 continues.

SUMMARY...A swath of 65 to 85 mph winds are expected across central
to north-central Indiana this evening.

DISCUSSION...A mature bow-echo has developed across east-central
Illinois with a strong rear-inflow jet. This bow has left a large
swath of wind damage over the past hour including a measured 68 mph
wind gust in Champaign, IL. 65 to 85 mph winds are expected to
continue across a relatively wide swath as it moves east into a very
unstable environment through the evening. Some embedded QLCS
tornadoes will also be possible, especially north of the apex of the
bow, but the strong measured wind gusts will be the primary threat.
