...OR coast and vicinity through this afternoon...
A midlevel shortwave trough and associated thermal trough will move
inland over WA/OR through the day. Isolated lightning flashes
occurred earlier this morning in northern CA with convection/minimal
buoyancy rooted above the 700 mb level, though this threat appears
to already be diminishing. Through this afternoon, colder midlevel
temperatures and associated steeper low-midlevel lapse rates will
spread inland over coastal OR where isolated, low-topped
thunderstorms will be possible.
