Points saillants

Cold temps are on the way for the second half of the weekend. Be prepared with extra layers and think about ending your day a little early.

Widespread surface hoar was observed by field teams in the Cameron Lake area on Tuesday. The unusual lack of wind may preserve this layer as new snow falls.
