DISCUSSION

Totals for December 9th show that northwestern Douglas County received around 1"-1.5" and areas near Crater Lake saw about 0.25". Northern Coos County had a report of almost 0.50". Radar and observations show light rain at the coast. There has been enough clearing from the heavier cloud cover that low ceilings are found in west side valleys and low ceilings and visibility for areas east near Klamath Falls.

Through Thursday morning parts of the coast, Douglas County and the Cascades are forecast to receive less than a quarter of an inch on average as the system is still bringing the main impacts to Portland and Seattle.

The next step in the forecast is for the high pressure that's off the coast of California to build, and this will bring a slight warm up to the area for the rest of the work week! Temperatures will on average be 10-15 degrees warmer than normal west of the Cascades and 15-20 degrees above normal for east side, equating to mid-/upper 50s and low 60s for both areas. We're also expecting to see more sun, especially into Thursday and Friday. Although the clearer skies ahead will help us warm in the afternoons, it will make the mornings colder. Friday and Saturday mornings are looking to be the coldest in the forecast period with low/mid-40s near the coast and into the Umpqua Basin. East side will have more mid-20s.

After the remaining showers at the coast, another chance of rain comes Sunday morning with light showers. Our next front that looks promising for more rainfall in Southern Oregon and Northern California will arrive Monday. The EC is still favoring a faster track, but overall Monday is the day that we can look for more precipitation. Snow levels will start at 8,000'-8,500' Monday and fall to 6,000'-7,000' Tuesday afternoon. This system is currently forecast to bring heavier rain into Curry County, with west side valleys seeing more rain than this past system as well. -9

AVIATION...10/12Z TAFs

Low ceilings and periodic rain showers are keeping coastal areas, including North Bend, at IFR/LIFR levels tonight. Other areas remain dry, but some areas (the Rogue and Illinois valleys including Medford and Klamath Falls) are seeing IFR to LIFR conditions.

Ceilings lift and skies look to clear for inland areas through the day today, while ceilings will linger over coastal areas and into Douglas County. These persisting ceilings look to hover near VFR/MVFR thresholds. Clearer skies tonight bring a chance for IFR/LIFR conditions tonight, and these details have been added to the TAF. -TAD/-9

MARINE...Updated 200 AM PST Wednesday, December 10, 2025

Winds subside tonight, but west swell persists north of Cape Blanco today with small craft conditions through Thursday morning. Conditions improve for the latter half of the week as high pressure builds over the region. Expecting showers over the waters through mid-week as well which could further reduce visibilities (fog/low clouds expected as well) over the next couple days.
