Chilly. 50 degrees (10C) at the house, a bit warmer in the sunny valley. It is getting noticeably darker.... I did not feel the sun on my back uintil the last couple of miles of the commute. The Wasatch Mountains cast a massive shadow across the valley, and the sun line is barely at downtown by 7:30 AM.

It looks like it will be warm again by friday, high near 100 (37-38C) with a return to the high 80's next week. I think the steady summer heat is beginning to waver as fall approaches.
