A Red Flag Warning will cover the Rogue, Illinois, and Applegate valleys from Monday afternoon through Tuesday evening as dry, gusty weather raises fire danger. A Heat Advisory follows Tuesday through Thursday, with some inland communities forecast to reach 105 to 110 degrees.

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.
