UPDATE

Aviation Discussion Updated.

AVIATION...12/06Z TAFs

Valley fog and freezing fog are expected overnight and Monday morning for many area valleys west of the Cascades and in the Klamath Basin. Fog has developed in the Grants Pass area, Illinois valley, areas north of Medford and Scott Valley. Fog may be dense, especially in the early morning. At Medford, expect LIFR conditions to develop between 06-09z then persist through the morning, lifting in the early afternoon. Similarly, expect LIFR in fog to develop at Roseburg around 09-10z then continuing through the morning before lifting and clearing in the early afternoon. Confidence is moderate that Klamath Falls will see LIFR again in the early morning, similar to yesterday.

Elsewhere, VFR conditions are expected through the TAF period. Coastal locations will remain VFR, although some fog from the Coquille Basin is forecast to drift into Coos Bay and briefly impact North Bend for a few hours tonight around 12Z.

PREV DISCUSSION

/Issued 222 PM PST Sun Jan 11 2026/

DISCUSSION...A stable upper ridge over the eastern Pacific Ocean and western United States remains the guiding influence in conditions across northern California and southern Oregon. This ridge looks to strengthen about midweek, with NBM probabilistic guidance giving Medford a 60% chance to see daytime highs above 60 degrees on Thursday and Friday. Dry conditions and above seasonal temperatures across the area remain in the forecast through the next week.

This stability supports air quality concerns continuing for low- lying areas in through at last Friday morning and possibly into next weekend. An Air Quality Advisory remains in place through the week to describe these hazardous conditions.

Cool overnight temperatures is keeping fog in the forecast for some low-lying areas. North Bend briefly saw fog on early Sunday morning, but forecast offshore flow should limit those conditions in the week ahead. Stable conditions will keep fog in the forecast for west side valleys, with freezing fog developing start the week. Midweek warming may bring overnight lows in the Rogue, Applegate, and Illinois valleys up above freezing temperatures. The Umpqua Valley remains above freezing temperatures and out of a Freezing Fog Advisory for early Monday morning. Northerly flow over the Upper Klamath Lake brought fog into areas around Klamath Falls this morning. With that pattern staying in the forecast, these areas have been added to the Freezing Fog Advisory.

Temperatures may ease slightly into next week as deterministic imagery shows the ridge developing a negative tilt that would decrease pressure over the area. Beyond that, ensemble guidance for the ECMWF and GFS models keep a ~60% chance for activity developing some time in the 10-12 day range. Long-term models of the upper air pattern fall short of showing any activity, so details about those possibilities remain vague. -TAD

MARINE...Updated 100 PM PST Sunday, January 11, 2026...Steep seas will persist for most areas from Gold Beach northward through this afternoon, then expand to all areas due to an increasing long period swell building into the waters today. Breezy south winds will diminish this evening into Monday, gradually becoming northerly later Monday into Tuesday.

Conditions improve Tuesday as seas lower to below 10 ft by early Tuesday morning. Another long period swell (peaking around 10 ft at 15 seconds) builds into the waters late Tuesday into Wednesday, so seas will remain swell dominated through early Wednesday. Meanwhile, northerly winds increase on Wednesday as the pattern transitions to a summer-like pattern under a thermal trough that lingers through the latter half of the week. Swell gradually subsides Thursday, but seas transition to wind wave dominated seas under gusty north winds. Expect another round of steep to very steep and hazardous seas through the latter half of the week. /BR-y

BEACH HAZARDS...Updated 100 PM PST Sunday, January 11, 2026...Long period swell is building into the waters today, resulting in a moderate risk of sneaker waves. This higher period swell will persist through Monday afternoon before diminishing into Monday evening. Guidance shows the potential for another sneaker wave threat beginning late Tuesday night and persisting through the day Wednesday.

If you plan to visit area beaches today into Monday or late Tuesday into Wednesday, please be aware of the dangers sneaker waves pose to beach goers. Sneaker waves can run up significantly farther on beaches than normal, including over rocks and jetties. These waves can suddenly knock people off of their feet and sweep them into the ocean. The waves can also move logs or other objects which could crush or trap anyone caught underneath. While sneaker waves can occur at any time, the greatest risk is on an incoming tide. Please be aware of the tides if venturing out onto the beaches. NEVER turn your back on the ocean! /BR-y
