Areas affected...parts of southern KS into northern OK
Concerning...Severe Thunderstorm Watch 587...
Valid 110743Z - 110915Z
The severe weather threat for Severe Thunderstorm Watch 587
continues.
SUMMARY...Strong to severe gusts remain possible as storms shift
east across southern KS and northern OK the next couple of hours.
DISCUSSION...A well-organized bowing MCS will continue shifting east
the next few hours. The downstream airmass is modestly unstable,
with latest mesoanalysis data indicating around 1000-1500 J/kg
MUCAPE. Vertical shear also will remain somewhat modest, but
sufficient for organized convection, at least in the short term.
Measured severe gusts in southern KS over the past hour have been in
the 60-70 mph range, and this may persist another 1-2 hours given a
well defined rear-inflow jet and mature bowing MCS. With time,
gradual weakening is expected across southeast KS/northeast OK where
earlier and ongoing precipitation ahead of the MCS will likely limit
downstream severe, especially east of the I-35 corridor.
