Areas affected...northern Arkansas into southern and eastern
Missouri and into southwestern and central Illinois

Concerning...Tornado Watch 32...

Valid 150045Z - 150245Z

The severe weather threat for Tornado Watch 32 continues.

SUMMARY...Hazardous weather potential -- including strong/damaging
winds, large hail, and a few, possibly strong tornadoes --
continues.

DISCUSSION...Latest radar loop shows a gradual change in storm
character over the past hour or so across south-central Missouri in
particular, where substantially more robust supercells have evolved.
Development has also increased southward into northern Arkansas.

The change in storm character coincides with -- and is likely
resulting from -- low-level moistening which is ongoing/spreading
northward with time. Storms increased substantially as dewpoints
rose into the low 50s, and now mid 50s dewpoints have overspread
much of southeastern Missouri and upper 50s to low 60s across
northern Arkansas and into the MO Bootheel. Given the highly
favorable flow field (veering and strongly increasing with height),
this increase in low-level moisture will likely support
corresponding increases in severe/tornado potential, including risk
for strong tornadoes potential evolving with time.

With storms now crossing the Mississippi River in west-central
Illinois, and in the next couple of hours farther south including
the St. Louis Metro area, a new Tornado Watch will likely be needed
across central Illinois and possibly into western Indiana.
