FORECAST:

A weakening trough will bring periods of light precipitation for today in a Southwesterly flow aloft. We may briefly see a few breaks today around noon. The freezing level will hover just below the 1700 meter range. The low to the Northwest will continue to send a few weak frontal bands our way over the next few days. The FL should fluctuate between 900 m-1600 m. Guesstimates: 8-12 cm above 1650 meters by Tuesday morning, 18-26 cm above 1650 meters by Wednesday morning, 20-30 cm above 1650 meters by Thursday morning. With the model spread there may be less precipitation for Tuesday and Wednesday. Questioning some of the model runs.

     Low to the Northwest will bring warmer air and periods of light precipitation for today.




    Fronts along the coast.

     Low continues to send warmish air and moisture our way for Tuesday.





     Warmer air looks like it hits a wall Wednesday. More of the same.

    INFORMATION & OBSERVATIONS:

    Looking warm and moist in the valley.

    Amazing how it does not fall off. Warming temperatures did make it collapse Sunday.

    Thanks for all the hard work opening the terrain, Blackcomb/Whister Ski Patrol!!:)
