   Concerning...Severe Thunderstorm Watch 487...

   The severe weather threat for Severe Thunderstorm Watch 487
   continues.

   SUMMARY...The severe threat continues across Severe Thunderstorm
   Watch 487. Severe gusts and perhaps a couple instances of hail may
   accompany the stronger storms that remain. The severe threat should
   gradually wane through the evening.

   DISCUSSION...Multicell and pulse single cells continue to percolate
   in intensity near the stationary surface front across northwestern
   OK. Occasional instances of severe hail and wind were noted with
   these storms earlier. Given the lack of strong steering flow,
   ongoing and earlier storms have likely overturned tropospheric lapse
   rates along much of the front, suggesting that the severe threat has
   likely peaked in coverage and intensity across northwestern OK.
   Nonetheless, a few intense updrafts have recently developed over
   Dewey County, so a few areas of pristine airmass may remain to
   support strong thunderstorms producing an instance or two of severe
   gusts/hail.
