The first significant heat wave of the summer is expected to bring 90-degree and triple-digit temperatures to much of Southern Oregon and Northern California this weekend, prompting heat advisories across several west side valleys, coastal areas and parts of far Northern California.

Historic trees across Medford, Ashland, Central Point, Jacksonville and other Southern Oregon communities are being highlighted as the Oregon Heritage Tree Program marks 30 years. Several locally significant trees tied to pioneers, industry, and historic events are included.
