The freezing level will rise to around 900 meters today dropping back to surface by tonight. The low will move east with another low moving down the outer coast of Vancouver Island on Saturday brushing the Coast range with dry cloudy weather. Sunday will see lingering cloud with warming temperatures before weak ridging on Monday. Next week is looking dry with April showers returning by the weekend. Guesstimates: 1-3 mm by Saturday morning, trace to 1 mm by Sunday morning, 0-trace by Monday morning.
