Valid 171200z - 181200z severe thunderstorm areas forecast... 

a few thunderstorms are possible across parts of California into the 
Great Basin on Thursday. Severe weather is unlikely. 

..synopsis and discussion... 
A shortwave trough will move southeastward across California and into the 
Great Basin with substantial cooling aloft and lift, as well as 
strong wind profiles. Instability will be weak across the region, 
but strong lift and steepening lapse rates aloft will likely result 
in sporadic lightning strikes from California across Nevada and perhaps into 
western Utah. Lift will be maximized Thursday morning across the 
Sierra with strong upslope flow, and will progress east across the 
Great Basin in association with a cold front. A few strong wind 
gusts may occur with precipitation along the front, but severe 
weather is unlikely.
