   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.
