Weather Synopsis

Warm, wet, and windy conditions continue Sunday night and through much of Monday for most of our forecast region. An atmospheric river (AR) maintains a narrow band of heavier precipitation pointed squarely at the Olympics and the Central/North Washington Cascades. The areas could see periods of moderate to heavy and high elevation snow. South of the main firehose, precipitation becomes a bit more uncertain. Locations from Mt Rainier to Stevens Pass will see precipitation, but exactly how much is hard to pin down. Subtle shifts in the AR axis would have a big impact on how much rain falls. South of Hwy 12, you probably won't see much, if any, precipitation at all. 

Temperatures continue to warm with this system overnight and into Monday. Snow levels climb past the tops of all but the highest peaks. There's no way to sugarcoat it; this storm is warm, and it won't help the snowpack. Winds also remain very gusty for the next 24 hours. With the pattern pretty much stuck, don't expect significant change until sometime late Monday afternoon or evening. 

Eventually, a high pressure ridge builds into the Pacific Northwest from the south and kicks the nasty rain north into Canada. The region will start to dry out, and skies will clear from south to north. The last lingering clouds and showers loiter in the Baker region on Tuesday morning. As the ridge continues to expand, warmer and warmer air floods into the region. Freezing levels continue to climb, and we'll start the clock on a prolonged period of warm, dry, and generally sunny weather.

Extended Weather Synopsis

A strong high pressure ridge will dominate our weather for the foreseeable future. There may be some minor daily nuances in passing bands of high clouds, potential nightly temperature inversions, valley fog, or afternoon high temperatures, but nothing looks too different day to day. Despite the date on the calendar, it will be unseasonably warm with 5000ft temperatures easily reaching into the 40s and possibly low 50s. I guess if it's not going to snow, it might as well be sunny. How long does the dry stretch last? You have to look pretty deep into the crystal ball to possibly see the end.

Previous forecast from Jan 11, 2026

The NWAC program is administered by the USDA-Forest Service and operates from the National Weather Service Forecast Office in Seattle. NWAC services are made possible by important collaboration and support from a wide variety of federal, state and private cooperators.

The 5000’ temperature forecast does not imply a trend over the 12 hr period and only represents the max and min temperatures within a 12 hr period in the zone. The 6-hr snow level forecast, the forecast discussion, and weather forecast sections may add detail regarding temperature trends.

The snow level forecast represents the general snow level over a 6 hr time period. Freezing levels are forecast when precipitation is not expected.

*Easterly or offshore flow is highlighted with an asterisk when we expect relatively cool east winds in the major Cascade Passes. Easterly flow will often lead to temperature inversions and is a key variable for forecasting precipitation type in the Cascade Passes. Strong easterly flow events can affect terrain on a more regional scale.

Ridgeline winds are the average wind speed and direction over a 6 hr time period.

The wind forecast represents an elevation range instead of a single elevation slice. The elevation range overlaps with the near and above treeline elevation bands in the avalanche forecast and differs per zone.

Wind direction indicates the direction the wind originates or comes from on the 16-point compass rose.

Water Equivalent (WE) is the liquid water equivalent of all precipitation types; rain, snow, ice pellets, etc., forecast to the hundredth of an inch at specific locations. To use WE as a proxy for snowfall amounts, start with a snow to water ratio of 10:1 (10 inches of snow = 1 inch WE). Temperatures at or near freezing will generally have a lower ratio (heavy wet snow) and very cold temperatures can have a much higher ratio (dry fluffy snow).

The label LT, is shorthand for ‘less than’.
