...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not forecast across the contiguous United States
on Monday.
...Synopsis and Discussion...
An upper trough is forecast to develop northeastward on Monday from
the East Coast across the western Atlantic and over the Canadian
Maritime provinces. Although some elevated storms appear possible
off the coast of Long Island and southern New England through the
day, latest guidance continues to suggest that this activity will
likely remain offshore. Another upper trough will move quickly
eastward across British Columbia and the Pacific Northwest through
Monday evening, eventually reaching the northern Rockies by the end
of the period. Surface high pressure initially centered over the
Southeast should shift slowly eastward to the Atlantic Coast, while
lee troughing develops over much of the High Plains. Modest
low-level moisture return should occur over parts of the southern
Plains and lower MS Valley through the period, but convection
capable of producing lighting appears unlikely across the CONUS
owing to a lack of instability overlapping large-scale ascent
associated with the upper trough moving across the western CONUS.
