..no thunderstorm areas forecast... 

thunderstorms are not expected Friday through Friday night. 

The longwave trough moving into the eastern states on Thursday will 
remain progressive during day 3 as it shifts off the U.S. East Coast 
by Friday evening. Meanwhile, low-amplitude to nearly zonal 
upstream flow will develop across the contiguous states. Height 
falls are forecast across Washington and Oregon to the northern 
rockies as a Pacific trough advances inland Friday afternoon through 
Friday night. 

Offshore low-level flow into the Gulf of Mexico will be maintained 
as a large anticyclone shifts east encompassing much of the U.S. 
East of the Mississippi Valley. This will continue to shunt 
moisture equatorward into the southern portions of the Gulf basin, 
precluding moisture return, while this expected synoptic pattern 
inhibits thunderstorm development.
