EUGENE, Ore. -- Area fog began to clear on Thursday morning. Eugene fog had already cleared early this morning, and Roseburg and Corvallis will continue to clear. A dense fog advisory is in place until 10 a.m. in the Umpqua Basin.
Thursday: Fog/Partly sunny. Highs near 50
Friday: Rain showers after 10am. Snow level 5,500 ft. Highs in upper 40s
Saturday: Rain showers. Snow level 5,500 ft. Highs in low 50s

Tuesday: Mostly cloudy w/ chance showers late. Highs in mid 40s
Wednesday: Mostly Cloudy w/ isolated showers. Snow level 5,500 ft. Highs in mid to upper 40s
With the fog clearing early, temperatures are expected to approach 50 degree by this afternoon. Also, sunshine will be with us much of the day. Clouds will start to return tonight, as the next system arrives on Friday.
Strong inversions are expected to continue through Friday, which means air quality issues will also continue below 1,500 feet. Thursday morning saw air quality sitting between moderate and sensitive to unhealthy. An air stagnation advisory is in place through 4 p.m. Friday afternoon. That coincides with a weakening frontal system set to bring showers on Friday afternoon andevening.
Shower chances will continue on Saturday and Sunday morning as an upper level trough comes ashore. Heaviest rain will be Friday night through Saturday along the southwest Oregon coastline. There is also a small chance of thunder along the coast, south of Heceta Head, on Saturday morning.
Light precipitation is expected to continue into Sunday morning, followed by high pressure moving back into the region. Like we have seen the last several days it does appear likely that a strong valley inversion will be in place on Monday. This means that stubborn fog and low clouds will be back in the southern Willamette Valley, as well as the Umpqua Basin.
Another weakening system arriving Tuesday night and Wednesday morning bring more light precipitation to the region. This type of pattern looks to continue into the next week or so. Unfortunately, we do not see any typical December rain events or mountain snow in the near future. That is beginning to be a problem after our very dry November. Current rainfall deficits are 7 and 12 inches below normal, with abnormally dry conditions across much of Western Oregon.
