Areas affected...portions of eastern Missouri into Illinois

Concerning...Severe Thunderstorm Watch 302...

Valid 242057Z - 242230Z

The severe weather threat for Severe Thunderstorm Watch 302
continues.

SUMMARY...Ongoing clusters of severe storms should remain capable of
damaging gusts and hail this afternoon. Additional clustering may
favor the more southeastern parts of the watch with time, but the
severe risk continues over much of the area.

DISCUSSION...As of 2050 UTC, regional radar analysis showed several
clusters of strong to severe storms ongoing from eastern MO into
parts of central IL. Concentrated along a remnant outflow boundary
from prior convection, storm evolution so far has been messy with
multiple storm interactions. Though a few supercellular structures
have recently emerged to the southwest. The upscale growth trend is
expected to continue as the environment remains unstable and
moderately sheared. Additional storms to the southwest are expected
to increase in coverage with time and should merge with the already
ongoing clusters. Eventually, one or more of these clusters may
evolve into a more organized bow/ MCS as it tracks along the remnant
outflow across far eastern MO and southwest IL. Given the tendency
for upscale growth/clustering and moderate buoyancy/shear, damaging
winds appear likely. Isolated hail will also be possible with the
more robust cores.
