...NO THUNDERSTORM AREAS FORECAST...

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

...Synopsis and Discussion...
A shortwave trough is forecast to rotate through the central/eastern
CONUS upper troughing on Thursday, progressing cyclonically from the
central Plains through the Mid MS Valley into the Southeast States
and southern Appalachians. Another shortwave trough is expected to
drop southeastward through the Upper Midwest early Friday morning.
Progression of these waves will help maintain upper troughing east
of the Rockies through Friday morning.

Farther west, expansive upper ridging will gradually shift eastward
throughout the day, ending the period extended from northern Mexico
into western British Columbia. A strong shortwave trough will
approach the Pacific Northwest coast, but is expected to remain
offshore throughout the period.

The surface pattern is expected to feature ridging centered over the
TN Valley, resulting in offshore flow across the majority of the
CONUS. Another surge of cold air is anticipated across the Plains,
helping to reinforce the cold and dry conditions already in place.
Westerly surface winds are forecast across the Gulf of Mexico, but
the development of a weak surface low just off the south TX coast
should preclude any low-level moisture from advecting inland.
Consequently, any thunderstorms activity should stay over the
western Gulf. Dry and stable conditions will prevent thunderstorm
development elsewhere.
