Total snowfall accumulations of 2 to 5 inches were common, with local amounts of 6-7 inches observed across portions of Laramie and Platte counties where narrow heavier bands resulted in periods of snowfall rates in excess of 1 inch per hour late in the evening on the 28th. In the mountains, 8 to 12 inches were common. A few brief road closures were noted along area roadways due to accidents, but generally remained opened.
