Isolated thunderstorms are possible along the Pacific Northwest

...Pacific Northwest coast...
A midlevel shortwave trough will move southeastward from the eastern
Gulf of Alaska to the Pacific Northwest coast by tonight.  A lead
shortwave trough and associated steep lapse rates/weak buoyancy will
support an isolated thunderstorm threat later today along the WA
coast.  The threat for isolated thunderstorms will gradually spread
southward along the coast tonight as the primary baroclinic zone
with the Gulf of Alaska trough moves inland.  Otherwise, cool and/or
dry conditions across the central/eastern CONUS will limit any
threat for deep convection.
