thunderstorms are not expected across the united states on monday.
...synopsis...
mid-level troughing will intensify rapidly over the eastern us,
helping deepen a significant surface cyclone off the new england
coast. at the same time, ridging will build over the western and
central us. as the mid-level pattern amplifies, a strong cold front
associated with the east coast low will sweep offshore scouring
low-level moisture from much of the continent. in its wake, a cool
and dry air mass will settle over much of the country, suppressing
thunderstorm activity.
