Weather Synopsis

The fire hose from Sunday/Monday's atmospheric river fizzled and drifted north of the border today, leaving the PNW with mostly sunny skies and unseasonably warm temperatures. Mild temperature will hold tonight through Wednesday, with daytime mountain high temperatures once again pushing into the 40s/50s and even the odd 60F.  We'll see a few high clouds tonight through Wednesday morning slip under an upper-level ridge, with otherwise clear skies. 

While Wednesday will start off mostly sunny, the atmospheric ingredients (warmth, unstable air mass and relatively sultry dewpoints for the PNW) are in place for convective weather, which will include heavier showers and thunderstorms. Scattered showers may flare up over the Olympics, Mt Hood, and southwest Washington Cascades by midday Wednesday, but the heaviest showers should flare up later Wednesday afternoon as a frontal boundary approaches. While all areas will see precipitation Wednesday night, the heaviest showers will likely form near and to the west of the Cascade crest and near Mt Hood and drift from the south to the north. The highest chances for heavy showers/strong thunderstorms featuring strong gusty winds, hail and lightning exist west of the Cascade crest during this period. If you're planning to be out in the mountains on Wednesday, make a plan to avoid getting caught out in stronger storms. 

A stacked upper low will drift closer to the coast on Thursday, keeping scattered showers, breezy winds, and the chance for afternoon thunderstorms in the forecast.  Snow levels will begin to slowly decline Wednesday night through Thursday, but temperatures will still be near or above freezing in many locations.

Previous forecast from Mar 25, 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’.
