Yesterday (Tuesday) in Cottage Grove, we hit 96-99°. Today and Thursday will be 90-94. It will then be a little cooler Friday through the Labor Day Holiday Weekend with high temperatures topping out in the mid to upper 80's. Normal high/low: 81/47.
Seeing some signs that high temps may cool down next week, but temperatures are generally expected to remain above normal through Sept 10 ( 2-3 days may be near normal). At this time, I think a more fall-like pattern will start to kick in sometime around Sept 10-15.
