September ends today with one of warmest days of the month with sun and highs in the lower 80s likely.
The warm weather continues on Friday and Saturday, both with highs in the lower 80s, before a frontal system starts to change the weather on Sunday.
Even with the change, Sunday should still be warm with partly sunny skies and highs near 74 in Spokane.
Temperatures cool down early next week with highs in the 60s Monday and Tuesday, but Wednesday should see a return of mild autumn weather. The high on Wednesday should reach 70.
Wednesday’s high at Spokane International Airport was 76.
The normal high for today is 67.
National Weather Service forecasters said a strong ridge of higher air pressure has strengthened along the Pacific coast, and warm air associated with the high is going to migrate eastward today, bringing highs in the lower 80s today through Saturday.
Lows should be in the lower 50s, cooling to the upper 40s on Sunday night and lower 40s on Monday.
At 7 a.m., it was 50 at the Spokane airport, 49 at Felts Field, 48 in Coeur d’Alene and Deer Park and 47 in Pullman.
