Areas affected...eastern Missouri across Illinois and into far
southwest Indiana.

Concerning...Tornado Watch 68...

Valid 012345Z - 020115Z

The severe weather threat for Tornado Watch 68 continues.

SUMMARY...Training supercells will continue along a warm front from
eastern Missouri to far western Indiana this evening.

DISCUSSION...A mature supercell is moving through the northern St.
Louis suburbs with another supercell east of Jefferson City. Thus
far, the maximum hail size with these storms has been golf ball
sized, but even larger hail is possible, especially as the low-level
jet strengthens this evening. A vorticity rich environment along
this warm front will support a tornado threat through the evening
with the WoFs suggesting a narrow corridor of 2 STP along the front.
WoFs 0-2km UH probabilities suggest the lead supercell will continue
to support a tornado threat for the next several hours with peak
probabilities in south-central Illinois.
