...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected on Thursday.

...Synopsis...
In the wake of a strong shortwave trough moving into the Canadian
Maritimes, a mid/upper cyclone is forecast to progress from the
Ontario/Quebec border vicinity eastward through Quebec on Thursday.
Strong mid-level flow throughout the base of this cyclone is
expected to extend from the northern/central Plains through the
Northeast. Even with these strong dynamics, extensive surface
ridging is expected from the northern Plains into much of the
eastern CONUS, promoting dry and stable conditions. Consequently, no
thunderstorms are anticipated. 

Farther west, a low-amplitude shortwave trough is expected to
progress across the Great Basin into the Four Corners region while
enhanced mid-level westerly flow associated with it spreads from
southern CA across the Southwest. Some modified moisture return is
anticipated across south TX late Thursday night/early Friday
morning, but this will remain well downstream of the shortwave
trough. As such, the lack of moisture/buoyancy ahead of this
shortwave will preclude thunderstorm development.
