    Areas affected...central and western Illinois...southeastern
    Missouri...and northeastern and central Arkansas

    Concerning...Tornado Watch 32...37...

    Valid 150342Z - 150445Z

    The severe weather threat for Tornado Watch 32, 37 continues.

    SUMMARY...Severe/isolated tornado risk to continue from central
    Illinois southwestward into central Arkansas.

    DISCUSSION...Latest radar loop shows that supercell storms that
    moved through the St. Louis area have evolved toward more of a
    damaging wind risk, as they have interacted with a drier low-level
    airmass east of the Mississippi River. With that said, damaging
    wind gusts remain likely, along with ongoing -- albeit somewhat
    lesser -- tornado potential.

    Farther south-southwestward along the convective band, more isolated/classic-looking supercells extend across southeastern
    Missouri, and particularly into northeastern and into central
    Arkansas. Specifically, strong rotation is noted within several
    storms in a zone from southeastern Reynolds/northwestern Wayne
    Counties in Missouri, southwestward to White County Arkansas. Along
    with risk for damaging winds and hail, greatest tornado risk appears
    to exist across this zone over the next couple of hours. Southern
    portions of WW 32 may be extended in time, beyond its scheduled
    15/04Z expiration.
