DISCUSSION

Satellite image shows low clouds with patchy fog in similar areas as yesterday. The low clouds did not break up in the Rogue Valley yesterday, but they did in portions of the illinois Valley late in the afternoon yesterday. The only difference today is the low cloud layer is not as deep as it was the past few days, and not as extensive, especially in the Illinois Valley. Therefore it could clear out at least in the Illinois Valley in the afternoon, but it still could remain socked in the Rogue Valley through the afternoon. As a result, afternoon high temperatures for the valleys have been adjusted lower. Also adjustments were made to the sky cover to better capture the low clouds in the valleys mentioned above.

It will be dry through the weekend. A weak front will run into a ridge Sunday morning. The worst case will be a few sprinkles in northwest Douglas and northern Coos County, otherwise it's likely to remain dry despite what the NBM solution is showing which is an outlier when compared to the operational, and ensemble model solutions. -Petrucelli

AVIATION...13/12z TAFs

Very little change in the pattern is likely in the next 24 hours. Areas of low stratus and fog are present in valleys west of the Cascades, resulting in IFR/LIFR conditions at Medford, Roseburg, and other area terminals. These conditions will persist through 18-20z Saturday. Some areas, such as Medford and Grants Pass may see little or no clearing, and just see ceilings lift higher late in the afternoon to MVFR.

Along the coast and just offshore. VFR conditions are likely to persist, but some localized fog and stratus is possible.

East of the Cascades, guidance suggest freezing fog and low vertical visibility could develop again in the Klamath Basin, including Klamath Falls early this morning, which would quickly clear to VFR by mid to late morning. -BPN

MARINE...Updated 830 AM PST Saturday, December 13, 2025

Winds shift to the south today, then increase through Sunday as a frontal system approaches the area. Conditions are likely to remain below advisory criteria until Sunday afternoon, but a brief period of steep seas is possible north of Cape Arago early Sunday.

Worsening conditions are expected Sunday evening into Monday as low pressure deepens over the north Pacific and a cold front swings through the waters Sunday night into Monday. More widespread advisory level conditions are expected to return late Sunday into Monday, with gales and very steep seas possible by early Monday morning. Additional frontal systems will maintain active weather with elevated winds and seas through next week. -BPN
