6AM Day 1 Convective Outlook for Sunday, February 1. 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.
