| Area Forecast Discussion National Weather Service Medford OR 404pm PDT Sunday August 30 2026 .Aviation discussion updated... /Issued 302pm PDT Sunday August 30 2026/ KEY MESSAGES... * Dry and windy conditions are expected on Monday, bringing critical fire weather concerns to the Scott and Shasta Valleys as well as broad areas east of the Cascades. Other areas may not reach thresholds, but have elevated concerns for similar conditions. * Tuesday marks a transition to active weather expected on Wednesday. A cold front will bring below seasonal temperatures across the area. Rainfall is expected west of the Cascades, with lighter showers possible to the east. * Light scattered showers and cool conditions are expected for Thursday and Friday. Zonal flow aloft behind a trough moving off to the northwest will bring summery weather across northern California and southern Oregon today. Coastal cities will see periods of gusty winds this afternoon as well as chances for marine stratus to develop overnight. North-northeast overnight winds may keep the skies clear or reduce development. An upper ridge passing over the area on Monday looks to raise daytime highs about 5 degrees for most Oregon counties. Northern Lake County may see temperatures increase by up to 10 degrees, while Siskiyou and Modoc counties will see smaller fluctuations. In addition to those warm and dry conditions, southerly flow will bring gusty winds into the Scott and Shasta Valleys, northeast Siskiyou County, Modoc County, southeast Klamath County, and southwest Siskiyou Counties. A Red Flag Warning has been issued for these areas as gusty winds and dry conditions reach critical levels. Tuesday will be a transition day ahead of midweek active weather, so forecasting may change as models get a better hold on that change. The overall pattern has not changed; A weak shortwave trough will swing over the area ahead of midweek activity. Temperatures look to cool by 5 to 15 degrees for most areas, depending on the timing and path of that shortwave. This trough may bring some initial activity to western Siskiyou County and along the Cascades. While slight thunderstorm chances (5-15%) remain in the forecast for these areas, CAPE values trending lower and moisture trending marginally upward might mean that some light showers be a part of any thunderstorms that do develop. Those chances do linger into Tuesday night, then ease on early Wednesday morning. On Wednesday, a cold front from an approaching low pressure system will bring cool temperatures and rainfall across areas west of the Cascades as well as some rainfall to the east. The most rainfall is expected over Curry County, with 1.0 to 1.5 inches at lower elevations and over 2 inches possible over terrain. Coos and northern Douglas counties as well as the Illinois Valley could see 0.75 to 1 inch of rainfall. Roseburg and westernmost Siskiyou County could see around 0.5 inches, with 0.25 inches possible in the Rogue Valley and northern Klamath counties. Eastern Siskiyou, southern Klamath, and northern Lake counties may see a few hundreths of an inch. Overall, impactful rainfall is not expected. However, as this is the first substantial rainfall in a while, water accumulation is possible in areas where debris blocks drainage routes. Additionally, oils may rise to road surfaces and bring locally slick conditions. Extra caution while traveling is advised. For Thursday and Friday, the low pressure system lingers to the west just off the Oregon coast and keeps a trough over the area. Cool temperatures will continue through the end of the week. Shower chances linger but decrease to 40-60% on Thursday and 20-40% through Friday. The higher chances tend to stay west of the Cascades, but southwest flow around the trough may help light showers reach Modoc and southern Lake counties late Thursday into Friday morning. Forecasting for next weekend is somewhat erratic, as ensemble members show a variety of outcomes. Meteogram guidance shows light activity continuing through the weekend. Beyond that, rain signals are a minority (10-20% for the ECMWF (European Centre for Medium-Range Weather Forecasts) ensemble, 5-10% for the GFS) and are fairly erratic but are definitely not absent. -TAD Marine Updated 230pm PDT Sunday, August 30, 2026...Gusty northerly winds and steep seas continue across area water this afternoon. Winds start to ease late tonight and seas fall below advisory levels near sunrise on Monday. An atmospheric pattern change will bring gusty southerly winds and the possibility of light marine showers on Tuesday. Winds and rain peak on Wednesday, with steep to very steep and hazardous seas possible for most area waters. Southerly winds ease on Thursday, but westerly swell may support continuing unsettled seas. -TAD Fire Weather Updated 200pm PDT Sunday, August 30, 2026... A brief, but strong warming and drying trend will continue on Monday. Winds will increase Monday afternoon as a trough approaches from the west. Wind and humidity conditions will reach critical levels in the Scott and Shasta valleys and east of the Cascades due to gusty south to southwest winds and dry humidities. A Red Flag Warning is in effect for portion of FWZ 280 (Scott Valley) and FWZs 281, 284, 285, and 624. On Tuesday, gusty winds will again reach critical levels in that area. But, humidities will be slightly above thresholds as temperatures trend cooler. There will also be chances for light showers and a 5%-15% probability of late of day thunderstorms, especially near the Scott Valley in west-central Siskiyou County, and in far northern Klamath County. A trough dominated pattern will follow for the remainder of the week with a strong cooling trend and increasing chances for rain. Gusty winds, and a wetting rain are likely from the coast to the Cascades, and in northern Klamath County. This will be followed by shower chances Friday into Sunday while slightly warmer temperatures remain below normal. The outlook for day 8-10, early next week, is for warming and drying.
