Officially Ottawa received about 18cms this past weekend. So definitely on the low end of the 15-30 range.
The next few storms will be largely passing to our south. Currently there is a storm hitting the US NE (radar pic below). Wednesday's storm may give us a few cms (second map) but will largely pass us to south (but affect southern Ontario too). The storm next Sunday/Monday (third map) will again largely pass to the south, if current model outputs are correct.
