Weather Discussion & OutlookA warm Ridge of High pressure will be over us today, just a few clouds spilling down the eastern side of that Ridge along the Continental Divide today, otherwise, clear skies over far western WY & across Idaho.
A fast moving upper level disturbance (Trof) will be zooming across the Pacific Northwest later today & tonight, passing by just to the north of us in Montana on Saturday. The southern end of that disturbance brushes across NW Wyoming Saturday afternoon.
That Trof will bring us some clouds, some gusty winds, possibly a few showers (valley rain shower/mtn snow shower). There is also a small chance of an isolated thunderstorm with that system Saturday afternoon. But most of the precip stays north of JH.
A dry, more Westerly flow will be over us Sunday & Monday. Next weather system passes thru on Tuesday, with some rain & snow showers possible late day or evening.
Much cooler Wednesday & Thursday, with some snow showers possible. Drier on Friday & Saturday, and slightly warmer. Look for highs to only be around 40 to 45 end of next week. At 10,000-ft. temps in the teens & 20's.
