   Concerning...Severe Thunderstorm Watch 246...

   Valid 040154Z - 040400Z

   The severe weather threat for Severe Thunderstorm Watch 246
   continues.

   SUMMARY...Severe storms over central Nebraska may continue to grow
   upscale later this evening toward the Missouri Valley. An additional
   watch may be needed downstream.

   DISCUSSION...Severe storms are rapidly moving southeast across
   central NE, and will soon be approaching the moist advection zone
   near/north of the stationary front. Other disorganized storms
   continue to evolve to the southwest into south-central NE and
   north-central KS.

   The storms approaching the GRI area may grow upscale as it
   encounters a moistening air mass to the southeast, and as outflow
   boundaries near the KS border push forward as well.

   The 00Z sounding from TOP shows MLCAPE over 3200 J/kg, and only a
   minor capping layer below 700 mb which should easily be breached by
   deep outflow with any MCS. A damaging wind threat may thus extend
   east of WW 246, and a new watch may be required depending on storm
   trends.
