Medford, OR – Parts of southern Oregon are facing the possibility of isolated thunderstorms through the overnight hours, with the greatest threat focused east of the Cascade Range and a few storms potentially reaching southeastern Jackson County and central Siskiyou County.
According to the National Weather Service in Medford, scattered showers with isolated thunderstorms are expected through Tuesday evening and into early Wednesday, primarily east of the Cascades. Forecasters said some of the activity may drift into southeastern Jackson County and central Siskiyou County later this evening.
The primary hazards associated with any thunderstorms include frequent lightning, gusty winds, brief heavy rainfall, and small hail. While widespread severe weather is not expected, any storm that develops could produce dangerous cloud-to-ground lightning.
The thunderstorm risk is expected to continue through approximately 5 a.m. Wednesday, with the highest chances remaining across portions of south-central and southeastern Oregon.
The National Weather Service advises residents and visitors to avoid exposed outdoor locations such as mountain summits, lakes, and large open fields if thunderstorms develop. Anyone who hears thunder should seek shelter immediately in a substantial building or hard-topped vehicle.
Outdoor recreationists, campers, and hikers should closely monitor changing weather conditions, especially in higher elevations where storms can develop quickly.
Residents are encouraged to stay weather-aware through the night and monitor forecasts for any additional advisories or warnings if thunderstorms become more widespread.
