Our heat is peaking... mountain snow should return by the weekend

Posted at 7:08 AM, Sep 25, 2023

Summer is making one last appearance as temperatures will begin to fall in the Treasure Valley starting Tuesday.

A powerful storm in the north Pacific is directing the first atmospheric river into the Pacific northwest with rainfall totals expected to be 2"-4" with higher amounts in the coastal mountains.

The low pressure system gradually weakens and moves inland throughout the week with another series of cold fronts cooling the temperatures and increasing rain chances by the weekend.
