Synopsis for the southern oregon coastal waters..Quiet conditions will continue through tonight. A warm front arrives Saturday, with gusty south winds and very steep wind- driven seas. These conditions will be hazardous to smaller crafts as seas become fairly high. A cold front will push in around Sunday night. A thermal trough is likely to develop along the coast Monday with increasing north winds.

Area Forecast Discussion National Weather Service Medford OR 234 PM PST Fri Dec 8 2023

SHORT TERM
Dry weather is likely this afternoon through tonight.
Low clouds are expected to gradually dissipate later this afternoon, although they could linger into the afternoon in the Scott Valley.
High clouds offshore will move into the area later this evening and tonight, but some of the high res guidance shows it will be a thin layer, therefore conditions will be favorable for temperatures to cool down pretty quickly after dark with near freezing overnight lows for many interior westside valley locations. Not to mention it will be cold east of the Cascades. With upper ridging building into the area tonight, the atmosphere will be stable. This in combination with existing moisture from all of the precipitation over the last several days will likely result in low clouds and fog/freezing fog later this evening and lasting through the morning hours Saturday for the interior westside valleys.

A warm front will move towards the area Saturday morning into Saturday afternoon. There's good agreement the bulk of the precipitation will remain north of our forecast area. However, some light rain could slip through the cracks into northern Coos and northwest Douglas County during the day Saturday.

Saturday night, a frontal system will slowly move southeast with precipitation also spreading southeast. However it should remain mainly confined to the coast, north of the Umpqua Divide and northern Cascades. Snow levels Saturday night will be around 6500 feet, therefore any road snow concerns will be mainly confined to the Crater Late area with a rain/wet snow mix around Diamond Lake.

The front will continue to move south during the day Sunday with precipitation spreading southeast into most of southern Oregon and western Siskiyou County. Precipitation will linger through Sunday night in the same areas. Snow levels will rise to around 7000 feet Sunday, then lower to around 6500 feet Sunday night, therefore road snow concerns will be confined to the Crater Lake area.

Monday, precipitation will diminish in the morning with dry weather expected for the afternoon that will last through Monday night. We could see low clouds and fog again for many of the interior westside valleys Monday night as upper riding builds in. -Petrucelli

LONG TERM
Tuesday through next Thursday. Tuesday starts with an upper ridge nudging into the west coast as the upper trough that brought precipitation to the region, and left continued low level moisture in the valleys. this will result in west side valley fog with weak offshore flow. Ensemble plots are in very good agreement with the upper ridge shifting to the east by Wednesday afternoon, with the next front moving rain into the coast Wednesday morning.
models then begin to diverge greatly, but the majority are keeping precipitation from the Cascades westward into Thursday. -Sven

AVIATION
08/18Z TAFs...Low ceilings and some fog still lingers in many valleys across the region this morning. There is also a higher cloud deck moving over head, which very well cloud slow the burn off of some of this fog. However, it is slowly lifting here in the Rogue Valley and there is some movement of these lower ceilings on satellite, which suggests these IFR to LIFR ceilings should lift by this afternoon with enough sun

By later this evening into tonight, lower ceilings and fog will build back into the valleys as high pressure builds in. Some of this fog could be freezing fog as temperatures in the west side valleys should be dropping into the upper 20's. The presence of higher clouds ahead of the warm front could keep us warmer than what is current in the forecast. Otherwise, anticipated more areas of IFR to LIFR ceilings later tonight in the valleys with VFR ceilings along the coast.

MARINE
Updated 200 PM Friday December 8, 2023...

Quiet weather will persist into tonight with seas around 6 to 8 feet in the waters. An approaching warm front early Saturday will result in increased wind speeds and a significant increase in wave heights.
Seas will become hazardous to smaller crafts Saturday afternoon into Saturday night. Swell periods are anticipated to be around 13 to 14 seconds with seas at 13 to 16 feet. The higher seas are anticipated closer to Florence and beyond 30 nm from shore. Wind waves will also contribute to the wave state, although we're not anticipating gale force winds in our waters. The cold front arriving Saturday night is not anticipated to pack much of punch with winds trending lower through Sunday. A weak thermal through develops along the coast for the start of next week.

Seas are anticipated to remain low(3 to 4ft) around Tuesday and Wednesday before the next swell group moves in.
