Synopsis for the southern oregon coastal waters - Strong north winds will continue through late week. Winds will be strongest, reaching gales, and seas will be steepest, with combined heights over 16 feet, south of cape blanco during the afternoons and evenings. North of cape blanco, wind will be more moderate though still gusting up to 30 kts with combined seas up to 10 feet. Conditions improve some on Thursday with winds easing to borderline gales, but gusty winds and steep to very steep seas will likely persist through the end of the week.

Area Forecast Discussion National Weather Service Medford OR Issued by National Weather Service Eureka CA 442 AM PDT Wed May 15 2024

Updated Marine and Aviation Discussion.

DISCUSSION
There is little change to the forecast this morning.
An upper level ridge remains in place, supporting continued above average temperatures and clear daytime skies through midweek. Low pressure in Canada is expected to flatten the ridge and bring cooler temperatures at the end of the week and into next week.

SHORT TERM...Widespread offshore flow has allowed for mostly clear skies across the area this morning except for a slug of isolated stratus just along the Central Oregon Coast. With clear skies, most of the areas has cooled off into the 50s.

Morning coolness won't last long, however, with high pressure peaking across the area today. Temperatures will warm slightly above Tuesday with highs near 80 in the Umpqua River Valley and closer to 90 near Medford. Any ragged coastal stratus this morning will quickly push offshore. Another warm day is expected in Brookings as winds continue channel down the Chetco valley.

A stronger though still shallow marine layer is expected to develop tonight, and this should result in more cloud cover/patchy fog along the coast north of Cape Blanco. The clouds could also push into portions of the Coquille Valley and the Umpqua Basin. -Spilde / JHW

LONG TERM...Thursday May 16th - Tuesday May 21st...The upper level ridge that lead to the warm temperatures earlier in the week will start to flatten as a trough moves down the British Columbia coast.
This will help push a thermal trough (heat low) from along the southern OR/NorCal coast inland. Typically, this leads to the warmest temperatures of a stretch inland while coastal areas, especially Brookings, cool off.

The trough then slides over the northwest U.S. Friday. Any precipitation associated with this looks to remain well to our north, so dry weather will continue in the region, but the resulting cooler, northwesterly flow will result in temperatures dropping (by more than 10 degrees in some areas) Friday afternoon compared to Thursday. Breezy northwest winds at the surface will pick up in the late afternoon into the evening, but not anything overly gusty.

While dry weather continues through the weekend, temperatures will cool each day under continued northwesterly flow as another shortwave trough starts to slide down from the northwest. This will gradually dig far enough south by Monday that about 10-15% of members of the National Blend of Models indicate some precipitation is possible in northern Douglas and Klamath counties. Another shortwave Tuesday will bring these chances further south and east, though model differences in the strength and timing of this system are numerous at this range. -CSP

AVIATION
15/06Z TAFs...Along the coast and just offshore, marine stratus is forming and moving from north to south along the coast and offshore with IFR ceilings. Right now, North Bend is on the cusp between VFR and IFR ceilings with the marine stratus just west of the terminal. We could see a situation where North Bend flips back and forth from VFR to IFR between 13 and 14z and a TEMPO group as added to the TAF, otherwise expect VFR ceilings into this afternoon before IFR ceilings return this evening and tonight. Also moderate to strong north winds between 30-35 kts are likely Agnola ate this morning into the afternoon.

Elsewhere, VFR conditions will continue through the TAF period with gusty afternoon and early evening breezes for the terminals.
-Petrucelli



MARINE
Updated 445 AM Wednesday, May 15, 2024...A thermal trough pattern will maintain gusty north winds and very steep and hazardous wind driven seas for all areas through tonight. Winds will be strongest, reaching gales, and seas will be steepest south of Cape Blanco during the afternoons and evenings. North of Cape Blanco, very steep and hazardous seas with strong winds are expected, but remaining below gale force.

The thermal trough pattern weakens some on Thursday and gales will ease. Despite this subtle improvement, gusty winds and very steep and hazardous seas will persist through the end of the week.
Conditions may improve overall over the weekend as the upper level pattern transitions, though expect conditions to remain hazardous to small craft for areas south of Cape Blanco as northerly winds continue. /BR-y/Petrucelli
