....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not forecast across the contiguous United
States through tonight.

....Synopsis...
A mid-level trough with multiple embedded shortwaves will move
eastward across the western CONUS through tonight.  One of the
embedded shortwaves is forecast to evolve into a deep-layer cyclone
near the ND/Canadian border by this evening, while the southern
portion of the trough moves across the Great Basin.  A warm front is
forecast to develop northward across the mid MS Valley and southwest
Great Lakes this evening into the overnight.  A strengthening
low-level warm-air advection regime overnight may result in a few
weak thunderstorms developing in the area centered over southern WI.
Elsewhere, a few lightning flashes are possible near the immediate
OR/northern CA coast early this morning before this activity wanes
as the primary mid/upper-level trough moves inland across the West.
