   Valid 131200Z - 141200Z

   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
   OREGON...

   ...SUMMARY...
   Thunderstorm associated with strong wind gusts and hail will be
   possible this afternoon and early this evening across parts of
   central Oregon.

   ...Central Oregon...
   An upper-level low will remain just offshore from the northern
   California coast today. To the east of the system, a diffluent
   upper-level pattern will be present from the Intermountain West into
   the Pacific Northwest. As surface heating takes place across the
   Pacific Northwest today, a pocket of weak instability will develop
   across Oregon, where MLCAPE is forecast to peak in the 500 to 1000
   J/kg range. To the northeast of the upper-level low, large-scale
   ascent will aid scattered thunderstorm development. The instability,
   along with moderate deep-layer shear and steep mid-level lapse
   rates, will likely support a marginal severe threat. The stronger
   rotating cells could be associated with hail and isolated damaging
   gusts.
