Chilly conditions for Thanksgiving, then even colder for the weekend. A storm system moves through the area Friday and Saturday, bringing snow and cold temperatures. Highs this weekend will only be in the upper teens and 20s, while overnight lows fall into the single digits. It is too early to provide exact snowfall amounts, but most of northeastern Wyoming and western South Dakota should receive a dusting of snow up to a few inches, with the highest amounts falling in the northern Black Hills.
