This week’s heat wave should stop short of triple digits, but fire danger will be sky high.
National Weather Service forecasters are calling for highs of 97 degrees on Thursday and 98 on Friday before the heat eases back to 94 on Saturday and 92 on Sunday in downtown Spokane.
Coeur d’Alene should be about three degrees cooler than Spokane.
A strong area of high air pressure has moved into the region and is allowing hot air from the south to migrate northward.
Forecasters had earlier called for highs of 100 to 101 on Friday, but backed off from that.
A weak low pressure system is expected to move across the northern side of the high pressure, which will hold temperatures in the middle and upper 90s instead of triple digits.
However, the weak disturbance will also create breezy to windy conditions, especially in the western Columbia Basin and along the east slopes of the Cascades on Friday.
Wind, along with low humidity and heat, will create a fire hazard for the region.
The weather service posted a hazardous weather outlook for the Inland Northwest.
“Temperatures this hot will increase the risk for heat-related illnesses,” forecasters said in the hazardous weather outlook.
“Drink plenty of fluids and make frequent breaks in shaded or air conditioned environments. If possible, plan outdoor activities for the early morning or evening hours.”
A heat advisory was posted through Friday for south-central and southeast Washington with highs getting to 103 degrees.
The only escape might be in the mountains, where highs will be in the 80s at about 5,000 feet in elevation near Sandpoint.
In Spokane, the normal temperatures for this time of year are 80 for a high and 54 for a low.
