Heavy snow hits the Cascades later this week as colder air finally arrives

Your forecast from the KGW weather team, updated several times daily. This includes the outlook around Oregon and in Southwest Washington.

PORTLAND, Oregon — Steady rain this morning breaks into afternoon showers with valley temps mainly holding in the 40s.  Monday night temps will be steady as warmer air arrives and Tuesday with patches of light moisture will see metro highs in the 50s.

A new storm comes in Wednesday with more valley rain and finally colder air, lowering snow levels during the day to 2,000 feet.  Colder air continues to pour inland Thursday as snow levels drop to 1,500 feet.  Hoping for a good 20" of snow at Mt. Hood resorts. Any lingering moisture Thursday overnight into Friday morning could produce a wintry mix of Friday showers, before Portland becomes dry and warms during the day. 

This week's pattern of colder temperatures and lowering snow levels is likely to continue through the month, meaning Mt. Hood resorts will finally begin building a base of snow.
