Valid 181200z - 191200z 


..no severe thunderstorm areas forecast... 


... 
organized severe thunderstorms are not forecast Thursday into 
Thursday night over the lower 48 states. 


..Oregon/Washington coast... 
A mid-level trough over the eastern Pacific will approach the coast 
during the period concurrent with episodic lobes of stronger 
large-scale ascent associated with smaller-scale disturbances. Very 
cool mid-level temperatures (-28 to -32 degrees c at 500mb) and a 
relatively moist low-level profile will result in pockets of weak 
buoyancy confined near the immediate coast. Convective showers and 
a few thunderstorms are possible. 


Elsewhere, cool/stable conditions over much of the contiguous U.S. 
Will preclude thunderstorm development.
