...NO SEVERE THUNDERSTORM AREAS FORECAST...
The risk for severe thunderstorms is expected to remain negligible
across the U.S. through tonight.
...01z Outlook Update...
Weak high-based convection near the central and southern
Appalachians has still been occasionally producing lightning the
past hour or so. However, this activity appears to be the lingering
remnants of convection largely driven by daytime heating and
orographic forcing, and probabilities for continuing development
through and beyond 01Z are becoming increasingly negligible.
Otherwise, widely scattered, generally weak thunderstorm activity
continues beneath cold mid-level air to the east of a slowly digging
mid-level closed low near the northern/central California coast, as
well as around the crest of downstream ridging across parts of the
northern Intermountain West and Rockies into the north central High
Plains. This may persist another hour or two, before the risk for
thunderstorm activity becomes increasingly negligible across most
areas. However, weak elevated moisture return and lower/mid
tropospheric warm advection could support a few weak thunderstorms
overnight across parts of the eastern Dakotas into western
