FORECAST:

A strong warm front will push into our zone this am in a Southwesterly flow aloft. Wet, warm, windy weather with the freezing level possibly spiking at 2000+ meters!, hopefully will hover in the 1800 meter range. Brunt of the moisture looks like it will be just South of the Whistler area. A cold front will push through early Saturday morning with the FL dropping to surface by the afternoon. The front moves through quickly with some sunny breaks in its wake Saturday afternoon. Mostly cloudy on Sunday as a upper level trough brings some periods of light snow. Similar for Monday with the chance of some sunny breaks. Guesstimates: 70-90 cm above 1700 meters by Saturday morning, 8-12 cm by Sunday morning, 1-4 cm by Monday morning.
