Posted: Dec 2, 2019 8:52 AM

EUGENE, Ore. -- The valleys saw areas of fog and clouds Monday morning which could stick around for some time. This is due to the low December sun angle and light winds. Outside of the valleys, sunshine is expected as well as milder temperatures. Highs at the coast on Monday will likely reach the low to mid 50s, while inland valley temperatures will only be in the mid 40s.

Fast Forecast:

Monday: Fog/Gradual Clearing. Highs in mid 40s
Tuesday: Fog/ Gradual Clearing. Highs in mid 40s
Wednesday: Fog/Mostly Cloudy. Highs in mid 40s
Thursday: Mostly cloudy w/ showers late. Highs near 50
Friday: Rain showers before 4pm. Snow level 5,500 ft. Highs near 50
Saturday: Rain showers. Snow level 4,500. Highs in upper 40s
Sunday: Mostly cloudy w/ slight chance. Highs in upper 40s

More valley fog is expected Tuesday and Wednesday morning as well, similar to Monday.

There is a small chance of precipitation Tuesday night into Wednesday morning as the tail end of a Canadian cold front clips us. This will mainly bring a chance of light showers from Corvallis northward into Washington.

The next bigger rain maker will arrive Thursday night into Friday. Models are still working on timing and strength, but unsettled weather is expected to continue through Saturday. The difference between this storm and the last several will be the relatively mild temperatures. This will keep snow levels between 4,500 and 5,000 feet. For reference, Willamette Pass is 5,090 feet and Santiam Pass is 4,766 feet.

The region needs the moisture after November ended with only 1.23 inches of rain falling in Eugene. That makes it the fifth driest November in 125 years of record keeping. The average Eugene rainfall for the month of November is 7.72 inches.

While this may sound troubling given that November is normally the second wettest month of the year next to December, which averages 7.8 inches, the months ahead are more critical for summer water supply and fire danger next summer. Although if this trend continues, next summer could experience severe drought conditions. Unfortunately, weather is only a spectator sport.
