FORECAST:

A low off the coast will bring dry overcast conditions for today in a Northeasterly flow aloft. Flurries are likely tonight into Friday morning as the low deepens with the brunt of the precipitation just South of us. The arctic high will push back in on Saturday afternoon with unsettled weather and dropping temperatures, Sunday is looking clear and cold as the artcic high dominates the pattern. Monday is looking clear and cold in the morning with unsettled weather expected in the afternoon. Looking dry and cold for most of the foreseeable future. Guesstimates: Trace to 1 cm by Friday morning, trace to 2 cm by Saturday morning, trace to 2 cm by Sunday morning. We may get as bit more snow if the front tracks differently, but more snow in Vancouver & Victoria at this time.
