....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorms appear unlikely across the Lower 48 on Wednesday.

....Synopsis...
On Wednesday, a shortwave trough will move across the Mid Atlantic
and weaken as it approaches the Maritimes, while a larger trough
amplification occurs over the northern Plains and upper MS Valley.
Here, a deep upper low will move from MN into Upper MI overnight,
with strong northwest flow aloft across the Plains. Meanwhile, an
upper high will remain over the Great Basin.

At the surface, high pressure will exist along the East Coast,
providing stable conditions there. A surface low will deepen across
the upper MS Valley in association with the aforementioned
amplifying upper trough, but dry trajectories from the south will
hamper destabilization. While lift near the low will result in
scattered precipitation across the upper Great Lakes on Wednesday,
the lack of CAPE should preclude any thunderstorm development.
