Medford, OR – A calm and foggy morning across southern Oregon will soon give way to changing skies as a new Pacific storm system edges toward the coast. Forecasters say the Rogue Valley and surrounding areas can expect increasing clouds, weekend rain, and a drop in temperatures heading into the start of November.
The Weather Pattern: Calm Now, Rain on the Horizon
According to the National Weather Service (NWS) in Medford, Thursday and Friday will stay mostly dry across the region, with highs near 67°F under partly sunny skies. However, clouds will build overnight Friday, signaling the arrival of a new Pacific frontal system expected to bring widespread showers to southern Oregon.
Meteorologists predict a 20–50% chance of rain by Saturday afternoon, with light showers spreading across the Rogue Valley and Eugene by evening. The first rainfall is expected after midday Saturday, and roads could become slick, particularly in areas where morning fog persists.
Forecast Details and Rain Timeline
Saturday’s temperatures will peak in the low 70s before cooling into the upper 40s overnight as moisture deepens. The National Weather Service warns that fog and drizzle may reduce visibility on Interstate 5 and highways 140 and 62 by late afternoon.
Residents planning for Halloween events or weekend travel are encouraged to keep rain gear nearby and drive cautiously in fog-prone areas.
“While rainfall amounts are not expected to be heavy, wet roads and patchy fog could make for challenging driving conditions Saturday afternoon and evening,” the NWS said in a statement.
Outlook for Sunday and Early November
Sunday is expected to bring a brief return of sunshine, with partly sunny skies and mild temperatures. However, this short break will precede another round of systems approaching from the Pacific.
Long-range models show a cooler, wetter weather pattern developing by November 5–7, with increased chances of steady rain across the Rogue Valley. Higher elevations east of Medford and along the Cascade Range may even experience their first snow of the season by mid-November, forecasters said.
This transition marks the typical shift into Oregon’s late-fall climate cycle, with more frequent precipitation and cooler days ahead.
Local Impacts and Safety Tips
As Oregon enters its early winter transition, residents should prepare for fluctuating road conditions and colder mornings. The Oregon Department of Transportation recommends checking road cameras and travel advisories before heading out, especially for those traveling through mountain passes where temperatures can drop rapidly at night.
Drivers are urged to slow down on wet pavement, maintain safe distances, and ensure headlights are on during foggy periods.
Outdoor enthusiasts planning weekend activities should also keep an eye on updated forecasts, as conditions can change quickly along the Rogue River, Applegate Lake, and other recreation areas.
Conclusion
Southern Oregon’s calm and crisp mornings will soon give way to light rain, cooler air, and a return to seasonal conditions. While the weekend showers won’t be severe, they mark the start of a wetter, chillier pattern expected to deepen through early November.
