We are tracking a large spring storm that will begin in Colorado’s southern mountains late Sunday night. As of now, expect snow, off and on, throughout the day Monday and then scattered snow showers on Tuesday. This is a cold storm, especially for this time of year, It has produced in every cycle and is part 2 of this years Co-Signature (CoSig) storms. Below is the results of this impressive repeating system. When we get a little closer I will dial in the amounts, but it looks like solid double digits as of now. This storm’s history tells us that the GFS can be trusted. Below are the results throughout cycles 1-4.
Last Cycle (4)
Wolf 14″, Telluride 14″ Vail 9″
Cycle 3 Storm a day early)
Vail 29″, Breckenridge 23″, Crested Butte 14″
Cycle 2 (Tracked more favorably for Utah)
Breckenridge 6″, Alta 20″
Cycle 1
Wolf 25″, Vail 15″, Crested Butte 16″
Here is a look at the signature troughs that occur with this system. Notice the similarities with the position of the ridge and the shape of the trough. Remember, the teleconnections drive the shape and strength of the storm with ENSO (LaNina) being the biggest influence.
