Isolated thunderstorms are possible along the Pacific Northwest Coast. ...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. ..Thompson.. 02/02/2021
