Synopsis for the southern oregon coastal waters.. Marine stratus and fog will receed through the afternoon. Impacting northerly winds are likely to return to the buoy 27 area Friday afternoon and evening, which will result in some high and steeps seas. Seas will become hazardous to smaller crafts as the thermal trough builds later this afternoon and evening. The thermal trough will then weaken slightly, yet persist into the weekend.

Area Forecast Discussion National Weather Service Medford OR 921 AM PDT Fri Apr 10 2020

DISCUSSION. A few changes were made to the cloud forecast this morning and afternoon. The latest visible image shows marine stratus over most of the waters and inland over most of Curry, Coos and northwest Douglas County. Te marine stratus will gradually burn off towards the coast during the day, but it could be a slow process and areas near and at the coast may not see any clearing at all today. Temperatures this afternoon away from the coast and where it's currently clear will be mild, but not as warm as yesterday. -Petrucelli

AVIATION. Along the coast and just offshore. Marine stratus is expected to remain in place through the day. There's a chance IFR ceilings could improve to MVFR later this afternoon, but confidence on ceilings getting to MVFR are low. Marine stratus will remain in place tonight into Saturday morning.

Inland, VFR conditions will continue through the TAF period. The exception will be in portions of the Umpqua Basin where marine stratus could develop, including Roseburg late tonight. The timing of when lower conditions develop in Roseburg could end up later than what's in the TAF, but for now we'll leave the timing at 8z. -Petrucelli

MARINE. Updated 900 AM PDT Friday, 10 April 2020 . Marine stratus and fog are likely to persist until afternoon northerlies and daytime heating cause it to recede. We'll see northerly winds build later this afternoon and evening. These winds will generate wind waves up to 10 and 11 feet between Gold Beach and Brookings and 5 nm away from shore. As a result, seas will become hazardous, especially for smaller crafts later this afternoon into Saturday morning. Winds may actually push a bit closer to shore than what is currently anticipated. So the hazardous seas warning may end up closer to shore in future updates. Plan on elevated and steep seas Saturday and Sunday as the thermal trough lingers into the weekend.

-Smith/miles

PREV DISCUSSION. /Issued 507 AM PDT Fri Apr 10 2020/

DISCUSSION . An upper level ridge will remain centered offshore through this weekend. Meanwhile, an upper trough will gradually shift down the eastern side of the ridge late today into the weekend but is expected to remain east of the area. Southwest Oregon and Northern California are expected to remain dry through the period. Inland areas will see temperatures cool slightly today compared to yesterday as the ridge weakens slightly. However, temperatures will remain above normal with highs in the lower to mid 70s for western valleys and near 70 for valleys east of the Cascades. At the coast, low stratus clouds have filled in most coastal areas and into coastal valleys. These low clouds will continue this morning and partially clear this afternoon. So expect cloudy and cool conditions at the coast today. Of note, the low stratus is not expected to be thick enough to support widespread drizzle, but some patchy drizzle is possible over the higher terrain, especially on north to northwest facing slopes, this morning.

Heading into the weekend, the CWA will remain under north to northwest flow with the ridge centered offshore and a deepening longwave trough centered to the east. This will bring slightly cooler temperatures across the area on Saturday. However, overall temperatures will remain normal temperatures across inland areas west of the Cascades with slightly above normal temperatures east of the Cascades. Additionally, areas from the Cascades east can expect gusty northwest winds to develop on Saturday as the upper trough shifts southward and a 25 to 35 kt mid level jet moves over the area. At the coast, a surface thermal trough will develop Saturday and persist on Sunday. This will bring breezy north to northeast winds to the coast and coastal mountains, especially south of Cape Blanco. North of Cape Blanco, nighttime and morning low clouds and patchy fog are expected on Saturday, followed by decreasing clouds on Sunday.

Early to mid next week, models and ensembles show good agreement that the upper level ridge will being to build inland with slightly warmer temperatures and dry weather expected. A weak low will move under the ridge and towards the coast Tuesday night and Wednesday but is expected to remain offshore and bring little or no precipitation to the area.

MFR WATCHES/WARNINGS/ADVISORIES. OR . None.

CA . None.

Pacific Coastal Waters . Small Craft Advisory until 5 AM PDT Sunday for PZZ350-356-370-376. Hazardous Seas Warning from 5 PM this afternoon to 5 AM PDT Saturday for PZZ356-376.
