    Areas affected...northern Arkansas...Missouri...and into western
    Illinois

    Concerning...Tornado Watch 32...

    Valid 142300Z - 150100Z

    The severe weather threat for Tornado Watch 32 continues.

    SUMMARY...Severe risk -- largely in the form of very strong/damaging
    winds -- will continue over the next several hours, while risk for a few/potentially strong tornadoes will also persist, especially over
    southern portions of the WW.

    DISCUSSION...Latest radar loop shows a broken/complex band of storms
    moving across Missouri and adjacent northwestern Arkansas. The most
    intense convection is occurring from central Missouri southward,
    just ahead of the advancing cold front.

    While a dry/deeply mixed boundary layer is evident over northern
    Missouri, dewpoints increase gradually with southward extent across
    the watch. This suggests primary risk across northern portions of
    the watch remains very strong/damaging gusts, while tornado
    potential increases with southward extent, across the Ozarks.=20
    Additionally, strong southerly low-level flow will continue to
    advect moisture northward, so tornado potential should gradually
    increase northeastward, with time.
