Winter Solstice occurred exactly when this post was published, at 8:28AM Pacific Time.

Happy First day of Winter! Yesterday was the shortest day of the year… it’s all good, expanding hours, of sunshine from now to summer! 🙂

But that’s not the only reason for this post. We may see strait effect snow start up on the East Coast late on Thursday.

The UWash model is not always very good at picking this activity up.

You can see the easterly winds from the Fraser Valley on the models.

Environment Canada is predicting snow fall from those easterly winds starting this afternoon.  UWash does not see that.

However, the NAM model does show some light flurries in the Lower Mainland in the late afternoon around sundown.

Friday a little stronger for the Island, pockets near Bowser and Denman/Hornby Islands.

The UWash model does indicate a stronger possibility of East Coast Strait effect snow on Friday morning.  It is a small time period, from 3-6AM.

I don’t expect to see any snow in Port Alberni on Thursday or Friday.  These kinds of events are usually very localized and unpredictable though so be careful if you are on the roads.

Snow on Christmas Eve?

The cat is out of the bag.  There are lots of predictions out there now that we could see snow for Christmas.  The most likely right now is that we will get snow on Sunday and it will stick around until Christmas.  I’ll leave more details to tomorrow morning after the high resolution models are done which will bring Monday into view.

For now… here’s the 24hr snow-depth-on-ground forecast for Monday 4AM.
