Areas affected...North-Central/Northeast Kansas...Southeast
Nebraska...Southwest Iowa...Northwest Missouri
Concerning...Severe potential...Watch possible
Valid 262330Z - 270100Z
Probability of Watch Issuance...60 percent
SUMMARY...Severe thunderstorm watch may be warranted if
thunderstorms develop over the next 1-2 hours. Hail/wind are the
main threats.
DISCUSSION...Weak short-wave ridging, in the wake of northern IL
MCS, is expected to shift east across the mid-MO Valley over the
next few hours. Latest water-vapor imagery suggests this is
underway, and brief subsidence will wane. This should become more
supportive for thunderstorm development over the next few hours.
Latest vis satellite imagery exhibits a substantial cu field from
north-central KS, arcing into southwest IA. Within this field,
several deeper towers are beginning to generate anvils along with a
few showers. Sustained low-level warm advection should aid
convective development over the next few hours, especially as LLJ
strengthens after sunset. CAMs support a considerable increase along
this corridor, just south of the wind shift, and this lends
confidence that a severe thunderstorm watch may be needed by 01z.
