FORECAST:
A mix of sun and cloud today as a weakening upper ridge maintains dry cold weather in a light Southwesterly flow. Sunday will also be unsettled with more cloud arriving Sunday evening as a front moves onshore for Monday. A series of wet warm and windy fronts will bring snow to the upper elevations through Thursday with a strong zonal jet stream. There is still a good chance for an atmospheric river event to hit the coast. The Freezing level will fluctuate over the next few days hovering around the 1200 meter range. A warmer impulse of moisture arrives from the Southern Latitudes Tuesday with a spike in the FL as high as 1800 meters. More on that as we get closer. After Tuesday the FL begins to slowly drop to round 1000 meters by Thursday. Guesstimates: 20-30 cm by Tuesday am, 25-40 cm by Wednesday morning, 20-35 cm by Thursday morning. These numbers will likely be adjusted as we get closer. Looks like we will get a proper reset in the alpine by next weekend.
