Areas affected...Southwest and South-central Missouri

Concerning...Tornado Watch 153...

Valid 270337Z - 270530Z

The severe weather threat for Tornado Watch 153 continues.

SUMMARY...A tornado threat is expected to continue for several more
hours into the early overnight period across parts of southwest and
south-central Missouri.

DISCUSSION...On water vapor imagery, a vigorous shortwave trough is
evident over the northern Ozarks. Near this feature, scattered
strong to severe thunderstorms are ongoing. Ahead of and to the
south of the storms, moderate instability is analyzed by the RAP in
southwest Missouri. Over the top of the unstable airmass, mid-level
flow is westerly at 40 knots. This is creating shear favorable for
supercells. In addition, the RAP is showing a 30 to 40 knot
low-level jet located over west-central and southwest Missouri. The
WSR-88D VWP at Springfield, Missouri has a looped hodograph with 0-3
km storm-relative helicity near 650 m2/s2. This will continue
support a tornado threat with supercells. Large hail and wind damage
will also be likely with supercells.
