   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Organized severe thunderstorms are not expected Friday.

   ...Western OK...
   An upper ridge axis will extend from TX to MN on Friday, with an
   upper trough rotating eastward out of NM into the southern Plains. 
   Considerable coverage of thunderstorms has developed this evening
   over NM, and is expected to spread northeastward overnight into west
   TX and western OK.  The associated high-clouds will slow/lessen
   daytime heating.  A few of the 00z CAM solutions indicate some
   concern for a few strong storms across parts of western OK on Friday
   afternoon.  If strong heating can occur, these storms could pose a
   risk of locally damaging gusts.  Due to the approaching cloud cover,
   will hold off on severe probabilities at this time and re-evaluate
   in later outlooks.

   ...Central/Northeast NM...
   Relatively cool mid-level temperatures will be present on Friday
   over much of the southwest US, with widespread weak CAPE leading to
   scattered coverage of afternoon thunderstorms across much of NM. 
   Forecast soundings over central/northeast NM show some risk of hail
   in the stronger cells.  However, parameters are rather weak for
   severe-caliber hail so will forego an upgrade at this time.
