Weather Synopsis

I won't sugarcoat it. It's wet out there... REALLY wet, warm, and windy. Many weather stations this afternoon are showing 0.2-0.35 inches of water per hour, temperatures in the 30s-40s, and strong and gusty winds. Yuck! Conditions won't change much as we head into the evening and overnight. A very strong atomspheric river remains zeroed right at the Pacific Northwest. Look for the heaviest precipitation rates from about Hwy 2 south to Mt Hood. These locations could see an additional 2-3 inches of water by Tuesday morning. However, this isn't just a west-side event. Very strong winds continue to carry rain and high elevation snow to locations further east. 

The bulk of the precipitation starts to drift south into Oregon after midnight, allowing rain and snow to taper for places like Mt Baker and Washington Pass. By day break, the firehose of moisture is aimed at Mt Saint Helens and Mt Hood, with areas further north experiencing a break in the action. As the precipitation moves south, colder air pushed into the area from Canada, allowing significant cooling. Unfortunately, as the snow levels drop, the moisture tap turns off. It's unlikely we'll see substantial snow accumulations at trailhead elevations. 

The break doesn't last long. The next tidal wave of moisture arrives Tuesday night, once again bringing very heavy precipitation, strong and gusty winds, and rising temperatures to the mountains. Areas near and west of the crest could see sustained periods of 1/4 to 1/3 inches of water per hour. Right now, this second system seems focused on the central Cascades from the Mountain Loop Highway to Mt Rainier; however, some models show it shifting further north. We'll have to wait and see. So, while there's some uncertainty about how much precipitation each location receives Tuesday night and Wednesday, rest assured, it's going to be wet and wild!

Extended Weather Synopsis

If you're looking for a break from the wet weather, you won't find it. Additional pulses of moisture continue to slam into the region, maintaining very stormy conditions. Once again, we'll be measuring precipitation in inches of water on Wednesday night and into Thursday morning. Unfortunately, mild temperatures just mean more rain at nearly all trailhead elevations. A trailing cold front finally arrives later Thursday. Once again, just as snow levels start to drop, we see a transition away from steady precipitation to more scattered showers. A weak high pressure ridge begins to build to our south Thursday evening, but right now, it doesn't seem to help us fully dry out. Instead, cloudy skies and periods of rain and snow showers appear to keep the mountains wet through the remainder of the week.

Previous forecast from Dec 8, 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’.
