Spokane, Washington – Dangerously hot weather will grip eastern Washington Tuesday, July 29th, with Spokane expected to hit 97°F under cloudless skies. The dry and stagnant heat could cause minor pavement buckling on local roads and increase fire danger across the Inland Northwest.

According to the National Weather Service in Spokane, calm morning winds will shift north around 6 mph by the afternoon, intensifying the heat. No rain is expected Tuesday, but scattered thunderstorms could develop by Thursday night as a weak Pacific disturbance pushes inland. Highs will continue to flirt with triple digits through Wednesday, topping out near 98°F.

Residents should limit outdoor activity between noon and 5 p.m., hydrate regularly, and check on neighbors without air conditioning. Those traveling on I-90 or US-2 should monitor for heat-related road damage or slowdowns due to construction. No official Heat Advisory has been issued yet, but forecasters warn conditions are approaching thresholds for one.

This heat wave, while not record-breaking, is part of a prolonged dry stretch impacting agriculture and water systems in Spokane County. Elevated wildfire risks remain, though no red flag warnings have been posted as of Monday evening.
