November 14, 2017

    Official word this am, Whistler will open on Friday.



WEATHER FORECAST:

A vigorous occluded front will push through today with moderate to heavy snowfall, in a Southwesterly flow aloft. The freezing level will drop and hover in the 1000 meter range with easing precipitation amounts into Wednesday.  FL could get as low as 800 meters? A weak upper trough will push through on Thursday with cooler temperatures and light snowfall to the valley, there may even be some breaks as the low dips South. Another weak frontal band on Friday with mostly cloudy skies and some flurries in a cool air mass. A very weak ridge may build for Saturday with unsettled weather before another front pushes through Sunday associated with a warmer air mass. There is much uncertainty in the models for Saturday into next week.  Will start posting on a regular basis once the mountain opens on Friday. Guesstimates: 40-60 cm by Wednesday morning, 15-30 cm by Thursday morning, 5-10 cm by Friday morning.


    Looking juicy for today.

    Should see some heavy snowfall in the alpine with strong winds on Tuesday.

    Low moves Southeast with another coming down the coast.


    Upper low sinks South and weakens.


    A weak dirty ridge will try to build Friday into Saturday.

    Possible ridging on Saturday but much uncertainty in the models.
