A Milder Week


After a week of huge powder down to very low snow levels, this week looks more "normal". That means we'll see more of a fluctuating snow level from day to day. The jet stream pattern has changed such that we're getting more of a westerly flow now, which means that each arriving storm will push a tongue of warmer air out ahead it. And behind each passing front, colder air will arrive again with lowering snow levels.

As of now (Tuesday morning), it appears that today, Thursday, and Saturday will be the milder days. Snow could switch to rain for a brief time along the lowest runs & lifts at Mt. Hood's ski areas, but any rain that falls will be short-lived, as arriving colder air will switch the rain back to snow within a few hours. The best days this week will be Wednesday and Friday. The stormiest day will be Thursday... with lots of wind and wet snow.

Unfortunately, this warmer storm cycle will take it's toll on the fantastic cold powder we've been spoiled by lately. While rain won't be much of an issue (except down very low), heavy/wet "Cascade Concrete" snow will be more common this week. Avalanche danger will become high again with the increasingly heavy top snow layer, so Heather Canyon at Meadows will likely be closed more than it's open this week... and backcountry skiing/boarding will be very dangerous.
