Valid 161200Z - 171200Z
...NO 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.
...MAXIMUM RISK BY HAZARD...
Tornado: <2% - None
Wind: <5% - None
