...western and central kansas...
an upper-level trough will move eastward across the north-central
u.s. on wednesday. ahead of the system, a broad low-level jet will
move through the upper midwest. at the surface, a cold front will
advance southeastward across the central plains on wednesday, with
moisture advection occurring to the south of the front over much of
the region. by early evening, the front is forecast to be located
across northern kansas. as low-level convergence increases along the
front during the late afternoon, convective initiation will become
likely. a broken line of thunderstorms is expected to develop in
northern and western kansas, moving southeastward into south-central
kansas during the evening. the nam forecast sounding at garden city,
kansas late wednesday afternoon has mucape near 750 j/kg with about
35 knots of effective shear and 850-500 mb lapse rates greater 8
c/km. this should be enough for isolated large hail with the
stronger cells. the hail threat should continue into the early to
mid evening, as a low-level jet ramps up across over the central
plains.
