Area Forecast Discussion National Weather Service Medford OR 429pm PDT Monday August 4 2025 oday through Sunday)... Overview: Outside of small chances for light rain showers and drizzle along/near the coast and Umpqua Basin Tuesday night through Wednesday night we are heading into a stretch of dry weather. Temperatures through Thursday will be below normal. By Friday, the heat will return with triple digits possible through the weekend and into early next week. This heat will also strengthen a thermal trough that may lead to a Chetco Effect this weekend. Overall, not seeing any reasonable chances for precipitation through early next week. Further Details: There is a shortwave trough exiting to the east today. We will transition to a mostly zonal flow starting today/tonight. Models are indicating a weak perturbation within this zonal flow, and this could spread PVA across the forecast area Tuesday night through Wednesday night. This could be enough energy to support weak rain showers and/or drizzle mainly along/near the coast and the Umpqua Basin. PWATs (Precipitable Waters) are over an inch across these locations and cannot rule out at least a small chance (15%-35%) for light showers. Not expecting much Quantitative Precipitation Forecast through this stretch, and wouldn't be surprised if very few locations actually accumulated much precipitation. Through Thursday, temperatures will be about 5-10 degrees below normal for this time of year. Its not until Friday we start to see temperatures back near normal. In fact, triple digits will be possible this weekend for many lower elevation/valley areas when a Moderate to Major Heat Risk will exist. Heat related hazards could become an issue this weekend into early next week as we enter our next heat wave. The heat will help increase the pressure gradient across the forecast area, and this will lead to increased wind speeds Thursday night through Saturday night (periods through the overnight and afternoon hours). While thunderstorms may not be an issue, we could start to see an overlap of critical wind speeds and RH through this heat wave which could lead to elevated fire weather concerns. See the Fire Weather section below for further details. The pressure gradient and wind direction could lead to a Chetco Effect as well, and temperatures could end up being close to 90 for Brookings over the weekend. -Guerrero Marine Updated 200pm PDT Monday, August 4, 2025...Relatively calm conditions are likely through Wednesday. A northwest swell will increase Wednesday, but seas are expected to remain below small craft conditions. A thermal trough will strengthen Thursday and likely persist through the weekend before diminishing Sunday evening. Through this stretch, we are expecting moderate to strong winds and steep wind-driven seas, especially south of Cape Blanco where the strongest winds are forecast. Fire Weather Updated 200pm PDT Monday, August 4, 2025... Weak instability on the back side of an upper trough looks to support one last period of activity. This afternoon and evening, slight chances of isolated thunderstorms are in the forecast for northeast Lake County. Any activity that develops should dissipate quickly into the evening hours. A stable pattern is in the forecast for the upcoming week. Through midweek, upper troughs pass to the north of the area. Impacts from these troughs look to be minimal, with drizzle or isolated showers at most possible over parts of Coos and Douglas counties. The troughs will help to keep temperatures at seasonal levels through the middle of the week. Towards the end of the week, an upper ridge looks to develop over the area. This could bring daytime highs 5 to 10 degrees above normal across the area. Drier conditions are expected as well. Additional warming may allow for diurnal breezes over terrain to increase slightly. Overnight periods of north or northeast winds over terrain could also bring moderate to locally poor overnight recoveries, especially over west side peaks and ridges. While critical thresholds are not currently in the forecast, this is a period of elevated fire weather concerns and will be considered closely as new guidance is available. -TAD NOAA Medford OR Office: Watches - Warnings - Advisories OR...None.
