| Area Forecast Discussion National Weather Service Medford OR 1100am PDT Sat Nov 1 2025 Updated Aviation Section... /Issued 322am PDT Sat Nov 1 2025/ DISCUSSION (Today through Friday)... Key Points: * Today: Rain chances increase (30%-95%) for areas along/near the coast and westside areas * Today: Chances less for Lake and Klamath counties (20%-50%) with higher chances for western Klamath near the Cascades * Monday/Tuesday: Another weak front and rainfall could precede a more active period later in the week * Increasing confidence for a weak to moderate atmospheric river event leading to impacts from both rainfall and strong winds Tuesday night through Wednesday/Thursday Further Details: Ridging at 500mb will continue to break down today as a weak front enters the region. Light rainfall chances will increase for areas along/near the coast before spreading farther inland through the day and overnight into Saturday morning. Overall, this front and dynamics are weak within this zonal pattern which will lead to mainly light rainfall amounts. The probability for 0.50"/24 hrs is roughly 30%-80% for areas long/near the coast and areas across northern Douglas County. In typical fashion, areas in Curry County will see the highest rainfall amounts. Other areas are not expected to see amounts near 0.50". For example, the Rogue Valley including areas like Medford only have a ~15%-20% chance for 0.25"/24hrs with this system through tonight. Realistically speaking, areas in/around Medford may only see 0.10" of rainfall when its all said and done. A zonal pattern will remain in place Sunday through early next week. Uncertainty exists for the Monday/Tuesday timeframe as a weak rainfall event may precede the more active time period around Wednesday. Differences exist between guidance so confidence is low, but it does appear another weak rainfall event could occur with details less certain. The probability for rainfall amounts of 0.25"/24hrs Tuesday morning to Wednesday morning is about 60%-90% with higher probabilities along/near the coast. On Wednesday, a deepening trough will enter the region with much stronger dynamics and adequate moisture as integrated water vapor transport (IVT) increases Wednesday into Thursday. IVT associated with the Wednesday system will be more widespread across our coastal areas as compared to the Saturday system where higher amounts will be mainly north of our area. For areas along and west of the Cascades, there will be a 50%-95% probability for rainfall amounts of 0.50"/24hrs Tuesday night/Wednesday morning through Thursday. Probabilities increase the farther west you go with highest amounts along/near the coast, especially Curry County. For Curry County, the probability for 1.00"/24hrs is around 60%-90% on Wednesday. While widespread flooding is not expected at this time, we will likely see nuisance type flooding with ponding on roadways. At this time, we are not expecting thunderstorms. Additionally, King Tides are expected Nov 4- 9 which could bring additional impacts to the coast as this system enters the region. Lastly, snow levels will remain high through next week, so we are not expecting any hazards from snowfall at this time. -Guerrero Conditions are VFR this evening, with lingering high clouds inland. The high clouds will clear late tonight, aiding in a return of valley LIFR/IFR low clouds and fog late tonight into Saturday morning. This includes the Rogue, Illinois, Klamath River, Scott, and Shasta valleys. Cities impacted will include Medford, Cave Junction, Grants Pass, Klamath Falls, Yreka, Happy the northwest. Gusty south to southwest winds at 15-20 kt with gusts up to 30 kt will develop at the coast around 15Z Saturday morning and be accompanied by light to moderate rain with MVFR (Marginal Visual Flight Rules) becoming the predominant condition. Coastal winds will diminish late Saturday afternoon with rain and the lower ceilings will persist into early Sunday morning. MVFR (Marginal Visual Flight Rules) and light rain will spread inland into the Umpqua Valley late Saturday morning, into Josephine County Saturday afternoon, then Jackson and western Siskiyou counties during Saturday evening with the rain and lower ceilings continuing into early Sunday morning. Areas of MVFR (Marginal Visual Flight Rules) and rain chances will develop east of the Cascades late Saturday night into Sunday morning. Marine Updated 300am PDT Saturday, October 31, 2025...Southerly winds will increase this afternoon as another front passes through. Winds will be strongest north of Cape Blanco. Steep seas will also become very steep early today and build into this afternoon. Gusty north winds will then follow with seas remaining high and steep into Monday. The pattern will remain active next week with a series of disturbances expected to produce episodes of strong southerly winds and high to very high seas. In other words, hazards are likely middle of next week. BEACH HAZARDS...Updated 200pm PDT Friday, October 31, 2025...Another round of hazardous beach conditions is expected Saturday. A lingering northwest swell will combine with another moderate to heavy long period swell tonight into Saturday. This will result in large breaking waves of 20-25 ft Saturday morning and afternoon. As this swell builds in late tonight, there will be a brief period of an enhanced threat of sneaker waves tonight. Avoid area beaches late today into Saturday. Impacts could include large breaking waves within the surf zone, which could inundate beaches and low lying shorelines. Waves could wash over rocks and jetties, and sweep unsuspecting people out to see. Never turn your back on the ocean!
