Medford, Ore. – Southern Oregon is heading into a hot, dry stretch with temperatures expected to climb well above normal through the weekend. The National Weather Service in Medford said west side valleys could see highs reach or exceed 100 degrees between Thursday and Saturday, raising concerns for heat impacts in Jackson, Josephine, and Douglas counties.
According to the weather service, strengthening high pressure over the Four Corners region is pushing warmer air into southern Oregon and northern California. Areas east of the Cascades, including Klamath Falls and Lakeview, will see highs in the mid-80s to low 90s, several degrees above average for mid-August.
Forecasters said the Umpqua Valley will remain slightly cooler than other west side valleys, though still warmer than seasonal norms. The heat combined with dry conditions may elevate fire danger across the region, especially in lower elevation valleys where humidity will be lowest.
Residents are urged to stay hydrated, limit outdoor activity during peak afternoon hours, and check on vulnerable neighbors and pets. While a slight cooldown is possible Sunday, temperatures will still run higher than average, keeping fire risk elevated. Additional advisories could be issued if conditions worsen.
