It's a beautiful sunny day all across the mountains with warm temperatures and generally light winds. You can expect very similar conditions on Sunday, with just a bit more of a breeze. A high pressure ridge will keep us warm and dry for the next several days.
Clear skies overnight will allow the surface to cool and develop temperature inversions in the mountain valleys and passes. The jet stream along the front side of the high pressure shifts overhead and causes wind speeds to increase. You'll experience moderate ridgeline and strong and gusty alpine winds overnight and into Sunday morning. Temperatures once again climb quickly during the day, with most sites pushing back above 40F.
The ridge fully shifts east on Sunday night and allows even warmer air to flow into the region. There will be a bit of overnight cooling, but in general freezing levels will be on the rise. Monday will be a full notch warmer than the temperatures we experienced over the weekend. Many weather stations should manage to break into the 50s. Along with the daytime warming, onshore flow increases in the afternoon. This will make the mountains slightly windier. Down-sloping winds should help drive temperatures in the east-side forecast zones slightly higher.

Extended Weather Synopsis
Our warm dry weather continues into Tuesday as the high pressure ridge very slowly drifts further east. A storm starts to approach the region Tuesday night and Wednesday. Weather models disagree about the timing and strength of this system. However, you should start to see increasing clouds sometime Tuesday night. A cold front eventually arrives and sends snow levels crashing down. At the moment, it's hard to say how much precipitation we'll see. We'll need to keep an eye on this pattern change over the next few days.
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).
