Chilliwack – A cool air mass hitting a moist air mass has the potential of rain for Metro Vancouver and the Valley, but East of Chilliwack may become a little white. So the White Christmas is a little late. Note that this is also dependent on elevation as well.
Thu 16:00: Tonight: Becoming cloudy this evening. Periods of snow or rain beginning this evening then changing to periods of rain overnight. Local snowfall amount 2 cm. Low plus 1.
