Valid 011300Z - 021200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorm potential appears low today and tonight.
An upper trough will rotate inland across the WA/OR Cascades this
afternoon, accompanied by cold temperatures aloft and strong onshore
flow. Scattered showers are expected across western WA, where very
weak CAPE will develop. While the risk of thunderstorms is low, an
isolated flash or two cannot be ruled out.
Elsewhere, dry and stable conditions will preclude thunderstorms
across the CONUS today.
