Medford, Oregon – Afternoon thunderstorms are set to rumble across southern Oregon through Friday night, bringing the potential for lightning, hail, and damaging winds to Jackson, Josephine, and neighboring counties.
According to the National Weather Service Medford office, isolated storms will fire up Wednesday, but Thursday brings a heightened risk with a larger number of storms, gusts reaching 40–60 mph, and higher chances for severe weather. Activity will focus on the Rogue Valley, I-5 corridor, and surrounding foothills before gradually shifting southeast into the weekend.
Communities from Grants Pass to Ashland should prepare for sudden downpours, brief hail, and power outages, especially Thursday afternoon into evening. Residents are urged to avoid outdoor activities on exposed ridges, secure loose property, and monitor local alerts for rapid changes. If thunder roars, move indoors immediately and wait at least 30 minutes after the last lightning before resuming outdoor plans.
Travelers on highways 199, 62, and 238 could encounter slick roads and reduced visibility. This multi-day storm pattern is typical for late July, but Thursday’s storm intensity could bring local flooding and isolated tree damage.
Thunderstorm chances taper Friday, with scattered storms lingering into Saturday morning. Further weather statements may be issued as conditions evolve.
