Quick post on the flip flop of Env. Can. Yesterday's afternoon forecast had dropped any mention of snow for Ottawa proper. However this afternoon's forecast they are calling for 5-10 cms. This is all due to the RGEM, Env Can. short term model making adjustments where it thinks precipitation is. I can sympathize with their predicament. On all models there is a sharp demarcation between no snow and a bunch. On all models, the northern edge of snow stretches from Lake Huron by southern Georgian Bay to the Ottawa region. 20-40 km separates no snow from this system to at least several cms. We could have a situation we Ottawa proper get a dusting while Kemptville get 10 cms. Or we cold have a situation where Pembroke gets zip and Ottawa gets the few cms worth. There is a small margin of error.
So, if its snowing tomorrow morning when you get up, then it's likely we'll get at least a few cms.
