Weather Synopsis for Monday & Tuesday
Updated to fix a typo in the Stevens Pass water amounts and confusing verbiage in the weather synopsis.
Active weather continues with a relative reprieve in some areas on Monday.
Post-frontal showers are winding down, mainly along the west slopes north of highway 2 this morning. A frontal passage Sunday night ushered in some slightly cooler air and the Passes are currently near or slightly below freezing with snow levels forecast to stay near or slightly below Snoqualmie Pass level on Monday. The bigger weather story will be a potent frontal system lifting quickly NE today. It's currently around the California-Oregon border and should spread increasing rain and snow to Mt. Hood and then areas of southern and central Washington State in the afternoon.
Greater impacts with this system are expected Monday evening as the frontal system brings a strong warming trend through the evening hours and rain and snow to many areas of the Cascades. Moderate to strong SE winds in the evening switch SW overnight as the front moves through, bringing a changeover to rain in the early morning hours for Snoqualmie Pass. On Tuesday, the detached low-pressure center moves toward Washington State, renewing periods of moderate to occasionally heavy rain and snow, particularly from I-90 southward with snow levels stuck just above Snoqualmie Pass.
