The multi-model outlook into start of December does not suggest any remarkable storms. For Halifax, some remnant rain or snow showeers today in cool west wind. The next two events (late Fri-Sat and mid next week) are the 10-20mm rain variety.
Cools down as December starts... maybe a setup for snow?

A wet start to November... for the period 01-12th, thinking 50mm would be close to normal. The locations in red (mostly NS having 100+mm) have already reached or exceeded their monthly average. A number of areas are over 200mm, with Middle River in Cape Breton coming out on top with 268mm.

The Atlantic coast of NS into Cape Breton had 100-200+mm rain in the first 12 days of November (I'll share maps later).
A cold west flow triggered patchy snow overnight. Will now have to consider roads, as snow accompanies our systems; including the weak one Thurs am & a stronger one late Sunday.
