A large storm system moved through the region this weekend, depositing over 20 inches of snow on Casper Mountain, with 5 to 10 inches of snow around Casper. Some of the higher valley locations recorded 2 to 3 inches of very wet snow, however most areas below about 6500ft did not change over from rain, or only did so very briefly.
