A deep trough of low pressure along the West Coast will move eastward across the Great Basin today, with several pieces of the storm bringing snows to the Steamboat Springs area starting this this afternoon or evening. The first part of the storm brings breezy southwest flow to our area today, with the best upward forcing staying north and south of us.
However, a cool front does pass through the area this evening, backing mountain-top winds slightly to the west and limiting accumulations as the Steamboat Ski Area is most favored with northwest flow. I would expect the best snows from this first part of the storm to be associated with this front Monday evening, leaving 1-4” of snow for the Tuesday morning report.
While we may see some snow showers for the first half of Tuesday, trailing energy from the Pacific Northwest brings a stronger cold front through northern Colorado later Tuesday, backing the winds to the northwest and bringing light to moderate snows for a time.
Amounts may be limited by decreasing moisture just as the winds turn to our favorable northwest direction, but we should see around 3-6” by a very cold Wednesday morning.
Showers will decrease for a time Wednesday before picking up again later in the day as a final wave in northwest flow brings another push of cold air and upward forcing. Again, moisture is sparse so I would expect 1-4” for the Thursday morning report.
At this point, a dry wave is forecast to move north of our area early on Friday before much warmer and drier weather is advertised to invade our area later in the day. The weekend forecast is uncertain , but generally unexciting as weak waves in westerly flow may suppress the driest air to our south and could bring clouds to northern Colorado.
