Valid 230100Z - 231200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected tonight.
...01z Update...
Surface low is beginning to deepen off the middle Atlantic coast
early this evening. Low-level warm advection will continue to focus
across the northern middle Atlantic into southern New England where
weak midlevel instability may prove adequate for lightning flashes
in the strongest snow bands.
Otherwise, isolated lightning flashes have been mostly confined to
offshore regions of the Pacific Northwest where marine influences
are contributing to a bit more buoyancy. Scattered weak convection
will continue this evening across western WA and a flash of
lightning can not be ruled out with this activity.
