...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
No thunderstorms are expected over the U.S. mainland on Thursday.

...Synopsis...

An intense upper trough over the Plains early Thursday will evolve
into a strong, closed synoptic low over the Midwest by Friday
morning. A surface cold front will extend from the Upper Midwest
into the southern Plains during the morning, and shift eastward
through the period, extending from the Lake Michigan vicinity toward
the central Appalachians to the central Gulf coast by Friday
morning. A lack of meaningful Gulf return flow ahead of this system
will result in dry and stable conditions ahead of the front, and
thunderstorms are not expected. 

An upper ridge will spread across the western U.S., with surface
high pressure in place over the Great Basin. This will result in
warm and dry conditions west of the Rockies.
