valid 161200z - 171200z
...no severe thunderstorm areas forecast...
...summary...
a few lightning flashes may occur over parts of the pacific
northwest on tuesday/tuesday evening, with isolated thunderstorms
also possible over the texas coast plain early wednesday morning.
...synopsis...
a series of mid-level troughs will progress across the northern
conus on tuesday, resulting in pronounced surface troughs becoming
established across the pacific northwest and the central conus.
cooler temperatures aloft will overspread the northern or and wa
coastline, resulting in scant buoyancy amid deep-layer ascent to
support a few lightning flashes during the day tuesday. a warm-air
advection regime should develop along the western gulf coast in
response to the glancing mid-level trough to the north, resulting in
the onset of moisture return. elevated buoyancy should develop
within the warm-air advection regime after 06z wednesday morning,
which may support isolated thunderstorm development across the tx
coastal plain.
