THE WEATHER PATTERN:

An Upper Level Low Pressure Trough (“U” shape ) is moving away from us as weak High Pressure tries to replace it. The graphics for days 1-3  show a weak cold front will be to our northwest today and falling apart as it attempts to move through Oregon. The graphics for days 3-7     Wednesday through Sunday show a cold front that will push into the Pacific Northwest next Sunday.
