Areas affected...Central Missouri

Concerning...Severe Thunderstorm Watch 585...

Valid 042304Z - 050030Z

The severe weather threat for Severe Thunderstorm Watch 585
continues.

SUMMARY...A local corridor of heightened tornado potential may
present itself over the next 1-2 hours across central Missouri ahead
of an eastward-migrating MCV.

DISCUSSION...Surface observations show a diffuse warm front draped
to the east/southeast of an MCV slowly migrating across central MO.
Recent analyses show a buoyancy gradient along this boundary, which
may act as a preferential zone for cell propagation. While
near-surface winds are weak (generally 10 knots or less), backed
flow along the boundary may support sufficient low-level helicity to
support a robust mesocyclone with an attendant tornado threat. While
very conditional, recent imagery from KEAX shows a few storms
already developing supercellular characteristics. Upscale growth
beyond the next 2 hours will limit the tornado potential, but a
near-term threat may present itself within WW 585.
