A weak storm moved through the northern Rockies today, brushing Idaho with clouds and a few mountain showers. As it moves out tonight, the clouds will diminish, but areas of fog and low clouds will shroud the Treasure Valley by morning. High pressure will continue to build through Monday, strengthening the valley temperature inversions and maintaining areas of night and morning fog and low clouds, especially in the western Treasure Valley.

Daytime high temperatures will be higher, but the inversion will prevent the valleys from warming to their full potential, which would likely be in the 50's without the inversion. Instead, valley temperatures will be in the 40's. High pressure will continue into next weekend, but a couple of weather systems will bring clouds and a chance of rain showers, one by late Tuesday/Wednesday, and another on Friday.
