Jack Frost was in a "solid" rather than a "dainty, feathery" mood on January 13th, when he decorated my bedroom windows. Still pretty, though, I think. We had something like another 6" of snow overnight and this morning and it's -16C (-24C windchill). On Thursday, just two days ago, Calgary saw a record high temperature of 13.2°C as Chinook winds swept through.
