Marine Weather and Tide Forecast for Selma, OR

AVIATION
12/00Z TAFs.. MVFR ceilings prevail north of Cape Blanco, including at North Bend, due to persistent onshore flow.
Winds have been gusty from the SSW this afternoon, peaking around 25-30 kt since about noon. Winds should ease a bit overnight into Thursday morning, but ceilings likely remain MVFR with a 30-40% chance of IFR developing after 04Z. There's a 60-80% chance of showers/light rain that could reduce visibility to MVFR at times.
Onshore flow increase south of Cape Blanco and ceilings lower to MVFR there as well overnight into Thursday. Gusty SSW breezes will pick up at North Bend again Thursday afternoon.

Moisture is more limited farther inland, though ceilings could easily lower to MVFR again at Roseburg overnight into Thursday morning with areas of higher terrain obscured from the coast ranges to the Umpqua Divide and Cascade Foothills. There is a 40-70% chance of light rain showers/drizzle (best chance Thursday morning) at Roseburg. Ceilings probably become VFR Thursday afternoon.

At Medford, mostly VFR is expected for the next 24 hours, though there is about a 20% chance of an MVFR ceiling for a few hours Thursday morning.

Mainly mid-level clouds are expected for areas south and east of Cascades/Siskiyous (Klamath Falls) with some mountain wave turbulence and gusty winds of 20-30 mph in the afternoon. -Spilde



PREV DISCUSSION
/Issued 255 PM PDT Wed Mar 11 2026/

SYNOPSIS... A strong atmospheric river will remain to our north through the rest of the week with some spotty showers and cloud cover over the region. A weak front will push into the area on Saturday morning before a strong area of high pressure builds next week. Temperature records in California will be at risk Monday and Tuesday.

DISCUSSION...

KMAX continues to show some echoes around Douglas County and just to the north of our warning area. However, surface stations are not reporting accumulating precipitation as of this afternoon. It's pretty similar conditions to yesterday, although winds are trending higher east of the Cascades this afternoon. 700mb winds increase to 50 knots east of the Cascades in northern Lake and Klamath County. However, we're not mixing that deep according to the forecast soundings, so wind gusts around 30 mph to 40 mph seem most probable through the evening hours over there.

Heading into Thursday, the atmospheric river and stationary front remain to our north in Northern Oregon with very little precipitation and impacts in our area. It looks like rain totals increase early Thursday morning near North Bend with 0.1 inches of rain, but that is looking like the highest total for our forecast area Thursday. The stationary front lifts a bit farther north Thursday afternoon and we could have some warmer air push in under this cloud cover. High temperatures trend a few degrees warmer compared to today.

Eventually by Friday night and Saturday morning, a short wave moving through Washington will push this stationary front southwards and some rain and perhaps a little snow will fall over the region above 5000 feet. Accumulation will be non impactful with Crater Lake seeing up to an inch of snow.

By Sunday morning a ridge will strengthen over the eastern Pacific with a low starting to spin up in the Gulf of Alaska. With this broad south west flow, a warm front will sweep through the area on Sunday morning with dry conditions within southern Oregon.
Temperatures will obviously trend warmer and take the first step in a gradual warm up into early next week. We'll test high temperature records on Monday and Tuesday in Klamath Falls, Alturas and Mount Shasta City. Confidence remains quite high in this warm up.

Finally, the ridge axis will nudge eastwards by Wednesday and ensemble data shows a cold front attempting to swing through southern Oregon. The QPF forecast varies significantly in the ensembles, so not that confident we'll get rain. The PoP forecast stands at 30 to 40 percent on Wednesday.

AVIATION (12Z TAFs)...

North Bend (KOTH) will likely (50%-80%) remain in MVFR conditions for ceilings throughout the valid TAF cycle with showers nearby.
Showers could impact the terminal starting tonight with very light rain which may lower ceilings further close to IFR (20%-30% chance).
Otherwise, KRBG should remain in VFR but will see ceilings close to MVFR through this period as moisture increases across the region.
KMFR may see these conditions overnight as showers/moisture spreads across the region with a small chance for MVFR (20%-30%) ceilings.
Klamath will likely miss out on the moisture in the lower levels and should remain mostly clear skies, but some concern overnight does exist for midlevel clouds.

MARINE
Updated 200 PM PDT Wednesday, March 11, 2026
Steep west- northwest swell will persist today. Gusty south to southwest winds will be common today and tonight, especially north of Cape Blanco as a front stalls to the north. This will maintain hazardous conditions north of Cape Blanco, with steep seas north of Cape Blanco and very steep seas north of the Umpqua River bar. While conditions improve tomorrow evening, the front will move back southward and could bring a period of gusty southwest winds and steep seas Friday and Friday night followed by a wind shift to northerly by Saturday.
