Chief Meteorologist Justin Stapleton‘s Daily Forecast Discussion:
Dense fog will again take over tonight, dropping visibility to less than a mile overnight with lows approaching 30 degrees. Areas of freezing fog will be back for folks headed back to work and shoppers looking to get the after Christmas deals. Because we might dip below freezing, some patchy freezing frost may coat area roads.
The inversion will keep valley residents socked into the fog for a third consecutive day and likely socked into highs only reaching the upper 30s as well. As you might expect, air quality will be an issue throughout the week, an Air Stagnation Advisory has been issued for the Willamette Valley. Elsewhere the coast and mountains continue to see sunny skies with highs well into the 50s.
By Friday night, a weak cold front will brush through Western Oregon and Washington, it won’t bring a good chance for any rain but may (I stress may) create some mixing of the airmass and finally break the dense fog in the valley for the weekend. Either way, we’ll keep the dry weather all the way through the end of the year! It looks like we might be welcoming in 2014 with some showers, we’ll see.
Have a great holiday week!
