A powerful spring snowstorm brought heavy, wet snow to areas in and near the Front Range Foothills and Palmer Divide.  Storm totals generally ranged from 2 to 4 feet in the Foothills with 1 to 2 feet across the Mountains and Palmer Divide. Front Range Urban Corridor had amounts ranging from 6 to 20 inches...with highest totals across the western and southern suburbs.  Denver International Airport flight cancellations totaled 852, almost all on the 16th. Accumulating snow on trees resulted in broken tree limbs and scattered power outages. Over 5,000 customers were without power on the 16th, and over 2,000 on the 17th. Xcel Energy brought in extra crews from surrounding states to help restore power and minimize outage times through the storm.
