We can expect some breaks today with unsettled weather.  A weak short wave trough will move through on Friday with periods of light snowfall and valley freezing levels. A warm front will gradually push through on Saturday with the freezing level beginning an upward trend into Sunday, likely rising to 1800 meters. A cold front will follow in its wake Monday with the FL dropping back to 800 meters. We can expect significant precipitation out of this system with 40+ centimetres expected above 1800 m on Sunday.
A cooling trend into Monday will bring a welcome 15+ centimetres by Tuesday morning.
