A weak disturbance will slide down the ridge off-shore bringing a chance for showers Monday afternoon and evening. Showers will be light for the most part and scattered along and west of the Cascades with only a slight chance for showers in the Rogue and Illinois Valleys. Showers will quickly move out of the region keeping us on track for a record breaking dry year. The high pressure ridge will build over the region Tuesday through Friday returning valley fog and mild and sunny conditions above the fog.
Fog will be most dense Christmas Day and the day after which means those traveling should be prepared for widespread areas of freezing fog and reduced visibility. The inversion will strengthen through early Friday which also will cause deteriorating air quality for low lying areas. A splitting storm is set to arrive late Friday into Saturday and for the most part will only bring increasing clouds to the area and mix up the atmosphere enough to clear out some of the valley fog.
Thanks for logging on and have a great evening!
