Valid 011200Z - 021200Z

....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
The risk for thunderstorms appears low on Wednesday.

....Synopsis...
A mid/upper-level shortwave trough initially over the lower Great
Lakes region is forecast to move quickly northeastward toward
northern New England and the Canadian Maritimes on Wednesday. In its
wake, a broad upper trough will remain in place across much of the
central/eastern CONUS. Farther west, a low-amplitude midlevel
shortwave trough will approach the Pacific Northwest during the
afternoon/evening.

Dry and stable conditions resulting from cold surface ridging will
continue to limit thunderstorm potential over most of the CONUS.
While some weak convection could accompany the shortwave trough and
attendant precipitation shield across the Pacific Northwest,
instability currently appears too weak to support any substantial
thunderstorm potential through the forecast period.
