For the forecast an dirty upper level ridge is building into our zone with unsettled conditions for today, but fairly sunny until later this afternoon. A warm front in a Northwesterly flow will bring clouds and moisture into our zone for tonight into Tuesday. Another upper level trough moves in for Wednesday with  post frontal showers and cloudy conditions for Thursday. Weak upper level ridge and surface ridge combo will bring drier and brighter conditions for Friday into the weekend. Guesstimates 5-8 cm by Wednesday morning, 15-20 cm by Thursday morning, 3-5 cm for Thursday day. Freezing levels hover from 500 to 1100 meters for the next few days.

Yesterday in the corridor there were numerous size 1 avalanches, Sa (skier accidental), Sc (ski cutting), Xe (explosive control). Some size 2 avalanches were reported Xe and to the north there was a size 2.5 Va (vehicle accidental) reported. Looks like we are in for an amazing day, read the advisory!!
