Areas affected…Eastern KS…far southeast NE…western
MO…southwest IA
Concerning…Severe potential…Severe Thunderstorm Watch likely
Valid 192255Z – 200030Z
Probability of Watch Issuance…95 percent
SUMMARY…A developing MCS over central Kansas is expected to
accelerate east-northeastward later this evening towards parts of
the Mid to Lower Missouri Valley. Damaging winds from 70-90 mph will
be the primary threat, most likely across eastern Kansas. A
downstream severe thunderstorm watch will be needed.
DISCUSSION…As alluded to in MCD 0839, increasingly widespread
severe wind gusts are expected as multiple intense thunderstorm
clusters over north-central to southwest KS consolidate by
mid-evening. The leading cluster across north-central KS should
spread into northeast KS initially, with additional low-level
warm-advection-driven storms possible farther northeast across the
Mid-MO Valley. Surface dew points are generally in the mid 50s to
low 60s across northeast KS and southeast NE currently and this may
mitigate eastward intensification in the near-term. But a plume of
higher surface dew points exists both to the south, emanating north
from OK, and farther east into central/northern MO. Eventual cluster
consolidation will probably yield eastward acceleration later this
evening with embedded bows spreading across at least eastern KS. A
plume of substantial MLCIN that will increase after dusk across
eastern OK and southeast KS, may result in the more prominent severe
wind threat arcing east-northeastward in time.
