...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Some thunder potential will be noted during the first half of the
period across portions of the Northeast. Isolated thunderstorms may
also be noted along the Pacific Coast during the latter half of the
period.

...Northeast...

Strong upper low is forecast to eject across the Delmarva Sunday in
response to a strong mid-level jet that will dig southeast into the
northern Great Lakes by the end of the period. Focused low-level
warm advection along the cool side of ejecting surface low should
encourage at least weak elevated convection from portions of PA,
east. Strongest convection may attain levels supportive of
generating a few lightning strikes.

...Pacific Coast...

Multifaceted upper trough will approach the Pacific Coast after
midnight Sunday night. Much cooler mid-level temperatures will
spread inland as a surface front surges across western WA/OR.
Post-frontal onshore flow and cooling profiles may support isolated
lightning within the strongest convection. Southern extent of
thunder threat may extend along the central CA Coast as heights are
expected to lower across this region as a secondary short wave
shifts into CA late.
