We’ve been dabbling out in the Great Lakes or southeast for so long, it seems about time to hone our skills out west.
At 953PM, MT, Idaho Falls was seeing clear skies and a temperature of 59 degrees. The western US was within a strong upper level trough, which was tiered and producing two separate surface features. A weak low and cold front lay over Canada, and at the base of the deeper trough, a low spun off the California coast. Idaho Falls sat between the two features, and was a position of calm. The trough was squashing monsoonal moisture to the osuth.
The low off the California coast will be the one to follow, as it will track along the existing jet structure. It will take until the afternoon on Wednesday, but it will arrive in eastern Idaho, pulling monsoonal moisture back northward. Rain and some isolated thunderstorms are expected in the evening in Idaho Falls, along with a few blustery gusts.

There is a big difference between the west and east of the Rockies. When amid a trough out west you can still get record highs. Let’s get the local perspective from KIFI in Idaho Falls
