The freezing level will likely hit a max of 1400 meters today falling to 700 meters by tonight.  Dries out into Thursday afternoon, when a warm front will bring light precipitation into Friday. Wet, warm, and windy weather for Friday into Saturday. Drier and cooler by Saturday night into Sunday as a cold upper trough moves through. Should see some nicer weather Sunday with some upper level ridging. Guesstimates: 15-20 cm by Thursday am, 12-16 cm by Friday morning, 70-90 cm above 1700 meters by Saturday am.
