...Synopsis...
Water-vapor imagery late this morning shows a large-scale upper
trough from WA southward into CA, and it is forecast to move east
into the Interior West through tonight.  Cold mid-level temperatures
(-28 to -31 deg C per the Reno, NV and Medford, OR 12 UTC raobs,
respectively) will foster fleeting pockets of scant instability and
support an occasional lightning flash with convection on the
windward side of the southern Sierra Nevada through early afternoon.
Elsewhere, a stray lightning flash may occur over the Great Basin
mainly later today but overall coverage is expected to be less than
10 percent.  Mostly tranquil weather conditions will prevail across
the Great Plains eastward to the East Coast.
