It's been interesting to watch the Env. Can. forecast go from no mention of snow before yesterday to yesterday's forecast of 2cm of snow for tonight to today's forecast of 2-4+ cms for tonight into tomorrow.
However there is a chance that we could still miss out. The NAM model is keeping most of the snow south of the Ottawa region so that Kemptville would get more than us.
PS. note that my Nov. 28th post made the call for snow.
