Don't expect this ongoing heat to go anywhere anytime soon...a Heat Advisory has been issued for the Columbia Basin, North-central Oregon, Simcoe Highlands, Columbia River Gorge, and the Foothills of the Blue Mountains. An Excessive Heat Warning has also been issued for the Yakima/Kittitas Valleys. Highs could reach 105°F. Stay hydrated!
A weather system is expected to bring dry thunderstorms across portions of the forecast area tonight into Wednesday. With how hot and dry we've been lately, storms that form are expected to be dry in nature, meaning lightning strikes may have the potential to start new fires. Outflow winds from storms may also lead to rapid fire spread.
