Synopsis for the southern oregon coastal waters - A thermal trough pattern will maintain gusty north winds and steep to very steep seas through the weekend. The strongest winds and steepest seas are expected south of cape blanco and during the afternoons and evenings. Conditions improve around Tuesday next week as the thermal trough gets disrupted by an upper level pattern change.

Updated aviation discussion.

AVIATION
18/18Z TAFs...Clear skies and VFR conditions will continue through this evening for the vast majority of the forecast area. The main impact to aviation inland from the coast will be gusty north-northwest winds this afternoon and early evening.

Along the coast, mainly north of Cape Blanco: A slight offshore component to the wind will likely keep the marine layer at bay through sunset with gusty north winds being the main impact. After sunset, stratus with MVFR ceilings will likely surge onshore.

Tonight stratus will surge from the coast into the Umpqua Basin, but it is unlikely to reach areas farther south. -Wright

PREV DISCUSSION
/Issued 414 AM PDT Sat May 18 2024/

DISCUSSION...Model agreement is very good into Friday, with the main points of uncertainty being the strength of a seasonable/relatively weak trough Tuesday afternoon into Wednesday night, and (with a larger extent of uncertainty) another at the end of the forecast, around Friday night into next Saturday.

Today looks to be the warmest out of the next 7 days, with readings near to several degrees above normal, which will be near the levels reached yesterday. After a solid week of much warmer and drier than normal weather, the shift to seasonable conditions for the next week will be noticeable. The other main characteristic, at least through Wednesday, will be continued stronger than normal afternoon into evening breezes, with winds mainly out of the west to northwest. Winds this afternoon will be stronger than yesterday (with gusts at 15 to 30 mph), almost as strong late in the day Sunday through Tuesday, then possibly at a slightly stronger peak for Wednesday.

Regarding precipitation, the chances will be late tonight into Sunday morning for Coos and northern Douglas counties with a few hundredths of an inch possible, then first and most significantly in that same area with the aforementioned cold front Tuesday afternoon into Tuesday evening, extending across at least southern Oregon Tuesday night into Wednesday with amounts mainly up to a tenth of an inch. Some break between systems is likely Thursday, then the next trough will move southeast into the Pacific Northwest. There is a wide variety of solutions regarding the southern extent and strength of this trough, with the possibility of either a quick glancing blow of minimal impact or the necessity of raising the current slight chances of precipitation. At the least, temperatures Friday into the start of the Memorial Day weekend are likely to be slightly below normal to near normal with coastal highs near 60, lower 70s on the west side, lower to mid 60s on the east side, and mainly 50s in the mountains.

MARINE
Updated 200 AM Saturday, May 18, 2024
A thermal trough pattern will maintain gusty north winds and steep to very steep seas through the weekend into early next week. Seas will be highest south of Cape Blanco around Brookings with waves up to 10-12 feet today. Meanwhile, areas near Florence and Coos Bay will see waves around 5 to 7 feet. Seas will be a combination of fresh swell out of the northwest and wind waves.

Seas will remain hazardous to small craft through the weekend and into early next week. The thermal trough will weaken slightly early Sunday morning through the afternoon, but seas will remain steep through the majority of the waters. It will then strengthen again late Sunday into Monday, with yet more steep to very steep waves.
Waves will then subside to around 4 to 6 feet across all the waters around Tuesday and Wednesday of next week. -CSP
