AVIATION...07/00Z TAFs

Marine stratus is bringing a mix of IFR/MVFR conditions to the coast and coastal valleys into the lower Umpqua Valley. The marine layer will gradually extend back into the central portion of the Umpqua Valley, including Roseburg, overnight. But, the stratus is expected to be faster to improve on Thursday morning, with VFR by 18Z.

Elsewhere, VFR conditions will continue through the TAF period with typically breezy afternoon/evening winds.

MARINE...Updated 700 PM PDT Wednesday, May 6, 2026

Sub-advisory conditions are expected through Saturday. There will be a period of near advisory level winds late tonight into Thursday morning just south of Cape Blanco to between 5 and 30 nm offshore from Gold Beach. Otherwise, light to moderate north winds prevail through Thursday evening, switching to light southerly for Friday as a weak front passes through the region. Also, west-northwest swell dominated seas at or below 6 feet will persist through early Saturday. A thermal trough develops over the weekend, bringing increasing north winds and resultant steep to very steep seas through early next week.

DISCUSSION...

A stubborn marine layer has kept temperatures a bit cooler than anticipated in the Umpqua Valley and Roseburg this afternoon. Some cumulus buildups have developed across the forecast area this afternoon, although we're not anticipating showers or thunderstorms today.

A marine layer will likely develop again tonight and linger in the Umpqua Valley and coast again. This could keep temperatures a few degrees cooler than what is currently in the forecast around Roseburg and portions of the coast. We should also see some more mist and fog along the coast as the boundary layer compresses under this upper level ridge.

Temperatures remain warm on Thursday with highs 10 to 15 degrees above normal for early May. Although we're not in fire season yet, the winds and humidities will create some elevated fire weather conditions east of the Cascades. Winds will be gusting close to 30 mph with humidities in the lower teens. We'll see those conditions change into Friday as a short wave approaches the Oregon coastline. Temperatures will cool a few degrees, although remain above normal for this time of year.

Once this wave passes, we'll see temperatures push 10 to 15 degrees higher for the remainder of the weekend and continue into next week. It looks like a thermal trough will develop during Monday and aid us pushing temperatures higher. We're currently forecasting to tie the high temperature record at KMHS of 88 degrees on May 11. No other records are at risk, although we'll remain well above normal, just not smashing through records through the remainder of the forecast through mid week.
