   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF
   NORTHEAST NEW MEXICO THIS EVENING...

   ...SUMMARY...
   A marginal risk for an isolated severe gust and hail exists for
   portions of northeast New Mexico this evening.

   ...Southern High Plains...
   The north extent of a low-level moisture plume over the southern
   High Plains may continue to foster additional storm development this
   evening.  Widely spaced thunderstorms east of the high terrain will
   gradually encounter weakening low-level lapse rates as the evening
   progresses.  In the meantime (through 9pm MDT), it appears the
   greatest risk for a strong storm or two may reside across parts of
   northeast NM where slightly stronger mid- to high-level
   northwesterly flow may aid in storm organization/vigor.  An instance
   or two of severe hail/wind may accompany the strongest storms before
   weakening later this evening.

   ...Upper OH Valley...
   Evening water-vapor imagery shows a potent mid-level shortwave
   trough over the southern Great Lakes and this feature will progress
   eastward into western NY/PA by early Monday morning.  Despite cold
   temperatures contributing to steep lapse rates, a paucity of
   low-level moisture resides across western PA this evening with
   surface dewpoints generally in the upper 20s F.  Low-topped
   convection will likely persist this evening but continue to weaken
   due in part to the loss of heating.  Therefore, general
   thunderstorms are forecast.
