The last two days of summer weather will warm the Inland Northwest through Wednesday when a low pressure system begins to bring showers and cooler temperatures.
Highs today and Wednesday will reach the upper 70s to lower 80s under mostly sunny skies in Spokane and Coeur d’Alene. Lows will be in the upper 40s and lower 50s.
A large low pressure system has formed off the Pacific coast and is initially allowing warm air to migrate northward into the Inland Northwest.
Moisture from the system will be evident today with streaks of middle and high elevation clouds crossing the region.
The low moves closer to the region Wednesday night and begins to send a series of storm impulses across the region through the weekend.
The chance of showers rises to 40 percent Wednesday night and Thursday while temperatures drop back to the middle 70s on Thursday and Friday.
Cooler air and more showers arrive on Friday night and Saturday with highs Saturday in the upper 60s. The chance of showers in Spokane goes to 40 percent through the weekend.
More cool weather is expected early next week. Autumn begins on Wednesday.
On Monday, the high at Spokane International Airport was 78. That was four degrees above normal. A year earlier, the high was 89.
At 7 a.m., it was 53 at the airport, 50 at Felts Field, 52 in Coeur d’Alene, 40 in Deer Park and 50 in Pullman.
