Mild temperatures will give way to excessive heat in the coming days, prompting the National Weather Service to issue a warning on Friday.
Dangerously hot temperatures are expected to settle into the Spokane area from Sunday through Tuesday, with daytime highs projected to reach triple-digits.
On Sunday, the high temperature in Spokane is forecast to be 100 degrees. That heat will linger through Monday and Tuesday, when the high temperature is still expected to be 99 degrees.
Wednesday will bring slightly cooler weather with a high temperature of 92 degrees.
The excessive heat watch issued by the National Weather Service blankets nearly all of Eastern Washington.
Forecasters cautioned that the hot, dry weather combined with possible dry lightning strikes early next week poses a fire risk.
