Updated AVIATION Discussion

AVIATION...02/12Z TAFs

VFR conditions prevail for most areas. The exception being along the coast and many of the valleys west of the Cascades where IFR/LIFR conditions in fog and/or low stratus will persist through the morning hours. Widespread fog is not expected in the Rogue Valley, but a few hours of "sunrise surprise" could impact the Medford terminal for a few hours this morning. Lower flight conditions are expected to clear out by late morning, with VFR then prevailing in to the evening.

PREV DISCUSSION

/Issued 214 AM PST Mon Feb 2 2026/

DISCUSSION...Satellite imagery this morning shows fog and low clouds along the coast and inland into coastal valleys, the Umpqua Basin and the Illinois Valley. Skies are clear for the remainder of the area with some scattered high level clouds moving through. There could be some early morning fog in the Rogue Valley around sunrise, but this should be shortlived with plenty of sunshine expected today. Once fog and low clouds clear by late morning, sunny skies and above normal afternoon temperatures are expected across the region today. High pressure develops today and will be a persistent feature through the week. This will bring similar daily conditions with areas of overnight/morning fog/low clouds in West Side Valleys that will give way to sunny skies and seasonably warm temperatures. Overall, the going forecast is on track and no updates are needed. Please see the previous discussion below for more details.

MARINE...Updated 200 AM PST Monday, February 2, 2026...Swell dominated seas and sub-advisory winds will persist through much of the week. Seas will remain elevated and steep into tonight, then lower below advisory criteria for a brief time on Tuesday. Steep seas are likely to return around mid-week as another building west swell arrives on Wednesday and combines with a persistent southwest swell for the remainder of the week and into the weekend. High pressure this week will maintain dry conditions.

DISCUSSION (Today through Saturday)...

Key Points:

* Little to no impacts expected with mostly quiet weather

* Light precipitation chances ending today

* Monday: Morning fog for westside valleys and some eastside areas

* Forecast turns dry with above normal temperatures this week - Warmest days will be Tuesday - Thursday - Record warmth possible for Alturas and Klamath Falls - Brookings may approach 70 degrees on Wednesday

Further Details:

Weak PVA aloft coupled with moisture advection has brought light precipitation to the area. By far and large, little to no impacts are expected with this progressive pattern. The forecast turns largely dry the upcoming week with above normal temperatures. In fact, high temperature records may be met at Alturas (Feb 4th/5th) and Klamath Falls (Feb 5th). Records are 65 (Feb 4th) and 64 (Feb 5th) for Alturas. Record is 59 for Klamath Falls. Each of these days we are forecasting high temperatures within a degree or two of these records.

A Rex Block (high pressure on the poleward side of a closed low) sets up at 500mb over the west coast starting Tuesday. This will keep the pattern stagnant through much of next week. The high of this Rex Block will be centered over the forecast area through middle parts of the week which will help aid our above normal temperatures for this time of year and dry conditions. This pattern does appear to break down Thursday into Friday as a closed low develops over the Pacific and enter the PacNW. This will bring our next chance at precipitation starting Saturday morning. A lot will depend on the strength of the high as this low could get pushed to the north. At this time, we are not seeing any noteworthy impacts, but we will need to keep an eye on snow levels and wind speeds. A lot will depend on the track of the low, but we have several days to analyze these details leading up to next weekend. All that said, not expecting widespread hazardous weather at this time.
