What happened

The episode as NWS PQR wrote it up.

TONIGHT AND TUESDAY. SOME LIGHT PRECIPITATION IS POSSIBLE TUESDAY AND
TUESDAY NIGHT FROM THE DEEP MARINE LAYER. THE UPPER LOW WILL
REDEVELOP WELL OFFSHORE ALONG 140W WEDNESDAY AND THURSDAY...CAUSING A

THE FORECAST AREA. THE OFFSHORE UPPER LOW WILL SWING THROUGH THE
PACIFIC NORTHWEST THIS WEEKEND AND EARLY NEXT WEEK FOR COOLER WEATHER
AGAIN.
