The last weekend of summer was a hot one, with Saturday's high temperature tying the record for the date (93°) in Boise. Our warm start the work week will give way to cooler temperatures starting Tuesday as an approaching cold front pushes wildfire smoke into the area causing hazy skies at times.
Behind the front, temperatures fall nearly 10° into Tuesday. The cooling trend continues throughout the week as an upper-level low rotates over eastern Oregon and southwest Idaho. Temperatures will dip into the 50's and 60's Thursday into Friday.
In the mountains, snow levels could fall to around 7000 feet. An inch or two of snow accumulation will fall at higher peaks Wednesday night into Thursday. Meanwhile, periods of rain impact the valley Wednesday and Thursday. There will be a brisk northwest breeze making it feel more like Fall a couple days early.
It will feel like fall throughout the remaining days of summer, but the Autumnal Equinox officially occurs early Saturday morning. However, sunshine returns and temperatures warm for the first few days of fall leaving us with a very nice weekend ahead!
