Summer to leave with a sizzle

The last week of summer is going to heat up with temperatures rising into the 80s by Wednesday. The warm up gets started today with a forecasted high of 73 in downtown Spokane. Higher air pressure is moving over the region, bringing a reurn to the late summer heat from earlier this month. Temperatures will go to the middle 70s on Tuesday and then the lower 80s on Wednesday. By Friday, the start of autumn, the thermometer may be pushing 90. This weekend will continue the trend with highs at or just above 90 on Saturday and Sunday. The high on Sunday was 71 at Spokane International Airport. Autumn starts with the fall equinox at 2:05 a.m. Friday. At 7 a.m., it was 56 at the airport, 59 at Felts Field and 57 in Coeur d’Alene and Deer Park.
