Weather Synopsis for Tuesday & Tuesday
A warm and wet New Years storm system will impact the Pacific Northwest on a strong westerly flow. A warm front lifts northward over the region today with increasing rain and snow along with rising snow levels and moderate to strong winds. Temperatures are already above freezing at Snoqualmie Pass and should rise above freezing by late morning at Stevens Pass, changing any pass level snow to all rain. The Mt. Baker Base is also likely to see a changeover to rain sometime this morning. Some cool air should linger east of the Cascade Crest, keeping snow throughout the day in Mazama and Washington Pass regions. Most areas west of the Cascade Crest stand to pick up significant precipitation today, but Mt. Rainier should partially block Crystal Mountain.
The cold-frontal rainband peaks Tuesday afternoon in the north and central Washington Cascades and then shifts southward to the SW Washington Cascades and Mt. Hood area during the evening and maintains over Mt. Hood overnight as a cold front moves into the region. The cold front should bring cooling and moderate to heavy rain and snow showers late Tuesday night through the day on Wednesday. Paradise, Mt. Baker and to a lesser extent Stevens Pass can all expect significant Snow accumulations after the rain turns back to snow, while Washington Pass should stay all snow throughout the event.
