   Concerning...Tornado Watch 164...

   Valid 302230Z - 010000Z

   The severe weather threat for Tornado Watch 164 continues.

   SUMMARY...Severe threat will shift east across ww164 this evening.
   New ww will likely be warranted downstream by 23z.

   DISCUSSION...Southern influence of northern Plains short-wave trough
   appears to be affecting northeast KS into extreme northwest MO early
   this evening. Surface front is advancing east with this feature and
   currently arcs from western IA-southeast NE-central KS. Numerous
   robust updrafts/supercells have evolved along/ahead of this boundary
   and large hail appears to be common with most longer-lived updrafts.
   Additionally, a few tornadoes have been noted with two long-lived
   supercells over northeast KS. Latest VWP data ahead of this activity
   is quite strong with 0-3 SRH on the order of 300-400 m2/s2. Tornado
   threat continues, along with large hail as this activity propagates
   downstream.
