...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast across the contiguous United
States.
...Synopsis...
The upper-air pattern today will feature a large-scale trough
exiting the East Coast as a ridge builds over the central U.S.,
followed by a trough moving into Interior West from the eastern
Pacific. A few weak thunderstorms may develop beneath a cold
mid-level trough along the Carolina coast later this afternoon.
Otherwise, dry offshore flow over the East Coast and Gulf Coast will
lead to tranquil conditions. A few widely spaced, weak
thunderstorms are possible over parts of the West.
