FORECAST:

A weak broad upper trough made landfall this morning in a Westerly flow aloft. Most of the energy is to the North but we will see overcast skies with some showers later this am into this afternoon, will likely see some sunny breaks as upper level ridging develops later today. An upper ridge will move into Southern B.C. Tuesday with sunny weather for Whistler. Wednesday is looking mostly sunny but should see some cloud move in during the afternoon as the next upper low moves into the South Coast. Thursday is looking like the wettest day of the week. Friday is looking mostly cloudy with some periods of light rain. Saturday will likely see unsettled weather with a chance of some showers, difficult to determine this far out but may see a wetter Saturday depending on which model you like.  Sunday could be cloudy with some sunny breaks with a slight chance of some showers. Back to rain by Monday as the carousel of upper lows continues to dominate the summer weather pattern. Guesstimates: trace-1 mm by Tuesday morning, 0 mm by Wednesday morning, 1-3 mm by Thursday morning, 4-8 mm by Friday morning, trace-2 mm by Saturday morning, 0-5 mm by Sunday morning.
