Our springtime weather is in full force this afternoon with plenty of sunshine and most locations seeing temperatures above 50 F. Moderate easterly winds continue to keep areas near and south of I-90 a few degrees cooler than places further north. However, wind speeds are dropping, and temperatures are on the rise.
Keep the sunscreen and shades handy; our spring-like weather isn't going anywhere. A strong high pressure ridge parked over the Cascades will keep us in a very predictable weather pattern for the next several days. Clear nights will allow temperature inversions to develop in the mountain valleys and passes. Even still, most sites will remain well above freezing. Even if it's a bit chilly to start the day, once the sun comes out, temperatures will soar. Generally light to calm winds will let you feel the full brunt of the heat. Most weather stations should easily reach into the 50s, with a few sites topping 60F.
If you like this weather, you're in luck! Sunday night and Monday look very similar.

Extended Weather Synopsis
Temperatures very slowly start to decrease as we head into Tuesday. The high pressure ridge begins to flatten ahead of an approaching trough. However, it may take a bit for this entrenched ridge to yield. Even as we cool, temperatures should remain well above freezing. Increasing clouds Tuesday night and into Wednesday herald the approaching storm. As precipitation starts to fall on Wednesday, temperatures rapidly drop from 9000 to around 4500ft. This should open the door for a much cooler and more active weather pattern for the remainder of the week.
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).
