   Valid 191943Z - 192115Z

   The severe weather threat for Severe Thunderstorm Watch 283, 284
   continues.

   SUMMARY...A corridor of damaging winds will remain possible near
   I-70 from Topeka eastward this afternoon. These storms are expected
   to reach western portions of the KC metro around 4pm.

   DISCUSSION...A cluster of severe thunderstorms, capable of damaging
   winds at times approaching 75+ mph, is progressing east around 45
   mph along the I-70 corridor this afternoon. Ahead of this cluster,
   visible satellite illustrates towering cumulus, suggesting a
   sufficiently unstable downstream environment. This is supported by
   the 18Z TOP sounding, which sampled steep low/mid-level lapse rates
   and ample northwesterly 700-500mb flow. Furthermore, dry air beneath
   500mb will enhance evaporative cooling within downdrafts already
   augmented by the aforementioned strong flow. All of these factors
   will likely maintain a threat of severe wind gusts (some possibly
   75+ mph) reaching the KC metro (especially western portions) around
   4pm.
