On Tuesday night a new low will develop over the Gulf of Maine and track across the Maritimes.

Normally, a track through the Bay of Fundy would guarantee mostly rain for Nova Scotia.  However, an elongated trough (dashed line on my pic) separates winds from the northeast on the north side and southeast on the south side.

Given the difficulty in predicting the location of this trough, the timing and amount of snow for the Atlantic Coast of Nova Scotia will be a challenge.

One weather model has consistently kept the coats in cold air, with lots of snow, especially along the Atlantic Coast:

The other has a less distinct trough, resulting in a general southeast wind, and a quicker changeover to rain along the Atlantic Coast:

My advice: everyone should limit their travel plans.  Given the likelihood the snow will be wet, and winds will increase, there may be power outages.

For those wanting to check the European Model for their communities, it is closer to model 2 (mostly rain for Halifax):

I’ll try and tweet updates tomorrow and Wednesday, especially to assist in timing for removal before the mess freezes.

Stay safe
