Valid 161200z - 171200z severe thunderstorm areas forecast... 

isolated thunderstorms are likely late Wednesday across parts of 
northern and central California. 

A low-amplitude upper-level ridge will move eastward into the 
Mississippi Valley on Wednesday as a couple of shortwave troughs 
move across the western U.S. Further west, an upper-level trough 
will approach the West Coast. Strong large-scale ascent, steep 
mid-level lapse rates and enhanced low-level flow ahead of the 
trough will make conditions favorable for a few thunderstorms across 
northern and central California Wednesday night. Instability will be 
too weak for a severe threat. Elsewhere across the conus, 
thunderstorms are not expected.
