Medford, Oregon – Triple-digit temperatures grip southern Oregon starting Saturday, with Medford and communities along the I-5 corridor bracing for a punishing heat wave that could push highs to 103°F. Residents from Ashland to Grants Pass face extreme heat through Monday night, raising the risk of heat illness, power issues, and outdoor dangers.
According to the National Weather Service, an Excessive Heat Warning takes effect at 2 p.m. Saturday, July 12, and lasts until 8 p.m. Monday, July 14, for Jackson, Josephine, and Curry counties. Daytime highs will reach 100-105°F, with western Siskiyou County valleys possibly topping 110°F. Lows will struggle to cool, hovering in the upper 60s. Authorities urge people to stay indoors, use air conditioning if possible, and avoid outdoor work during peak afternoon hours.
Roads like Interstate 5 will be especially hazardous for drivers and travelers, with vehicle overheating and pavement issues likely. Schools and local agencies may adjust activities or open cooling centers as heat builds.
Drink water frequently, check on vulnerable neighbors, and never leave kids or pets in parked cars. Power grid strain is possible—charge devices and prepare for potential rolling blackouts.
This heat wave marks one of the most intense July events in recent years for southern Oregon. Relief looks unlikely before Tuesday, with highs remaining near 103°F into the middle of next week.
