Enjoy the brisk January sunshine while you can, Ottawa-Gatineau, because dark clouds are going to descend tomorrow — and they'll be bringing miserable weather with them.

Environment Canada has issued a freezing rain warning for Tuesday, one that covers the national capital region along with a wide swath of eastern Ontario and western Quebec.

Snow or ice pellets are expected to arrive late Monday night, changing to freezing rain Tuesday morning as the temperature hovers around the freezing mark.
