Weather Synopsis

Make sure to grab your warmest jackets and gloves. The Pacific Northwest sits just on the leading edge of a high pressure ridge that stretches well into the Alaskan Arctic. Northerly flow aloft will bring a steady stream of dry frigid are into our area for the next several days. 

A few low clouds and flurries will linger into the evening near Mt Rainier, Mt Hood, and sections of the East South zone, but they won't last long. Dry air pushing in from the north will help skies clear. Look for overnight temperatures to dive, with many 5000ft locations bottoming out close to 0F. Yikes, that's cold! Easterly winds will peak this evening as what's left of a dry front passes over the area. While not a significant east wind event, they'll be noticeable along the Cascade Crest and through the Passes. Combine moderate winds and very cold temperatures and you get wind chill values well below zero. 

After a very cold start to the day, sunny skies will help temperatures warm slightly. A few mid to high clouds may pass over the northern portion of the region, but shouldn't have much of an impact. It's hard to say exactly how far south they will drift. Overall, it will be a beautiful, sunny, but chilly day. 

The pattern generally repeats Tuesday night into Wednesday. Clear skies let temperatures drop overnight and sunshine helps them warm during the day. Easterly winds may increase late Wednesday afternoon as a significant winter storm undercuts the high pressure ridge far out in the Pacific. This storm won't truly impact our region until at least Thursday, but it's the start of a pattern shift. Until then, bundle up and stay warm!

Extended Weather Synopsis

A storm system undercuts the high pressure ridge Wednesday night on its way to California. This should set the stage for a stronger E-wind event. Look for the highest winds near Mt Hood and along the Cascade Crest from Stevens Pass south. The wind event should peak early Thursday morning. At the moment, it's hard to say how much, if any, precipitation this storm will bring to our region. Bands of snow could rotate up from Oregon. As a result, the best chance for snow will be near Mt Hood and the Southern forecast zones. If the storm ventures this far north (and that's a big "if"), precipitation should turn to showers by Friday. Whether we see significant snow or not in the Thursday system, at least the door will be open for additional storms following over the weekend.

Previous forecast from Feb 10, 2025

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’.
