Date:

This morning’s radar show’s precipitation extending from the California coast to Utah. A deep atmospheric river of moisture floods into the Elk Mountains this afternoon. The jet stream sags over Colorado, so the new snow will be accompanied by moderate to strong winds near and above treeline. Snow showers kick off this afternoon, but the real show doesn’t start until sunset. Snowfall ramps up through the night and we should see rates exceeding 1″ per hour from midnight into tomorrow morning. Lingering orographic showers will fuel a couple more inches tomorrow, but we’ll see a lull in the action as the jet lifts northward. There is some model uncertainty on the next surge of moisture, which will show up sometime mid week.
