   Day 2 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   1125 AM CST Tue Jan 23 2018

   Valid 241200Z - 251200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Isolated thunderstorms will be possible across coastal areas of the
   Pacific Northwest Wednesday into Wednesday night.

   ...Discussion...
   A relatively progressive mid/upper ridge will shift eastward from
   the Great Basin and northern Rockies to the central/northern Plains
   through the period. This progression will occur while an upstream
   jet core impinges upon the Pacific Northwest coast Wednesday. In
   turn, heights will gradually lower along the West Coast and
   temperatures will cool, with 500mb temps below -30 C overspreading
   parts of Washington, Oregon, and northern California. Concurrently,
   a weak surface cold front will move onshore through the day,
   resulting in a modest steepening of low-level lapse rates. Near the
   coast, forecast soundings depict adequate boundary-layer moisture
   for buoyancy profiles that may support a few deeper convective
   elements Wednesday into Wednesday night. These stronger convective
   elements will be capable of isolated lightning strikes as they
   approach shore.
