10-15cm for North Grenville

The snow has started over eastern Ontario at 2pm and should continue until about midnight. We can expect between 10-15cm of snow in Kemptville. While Environment Canada has not issued any warnings, the driving should still be nasty. Roads are already snow covered and slippery. To the southwest over Lake Ontario, some rain and freezing rain is mixing in as well. Winter Weather Advisories are in effect for upstate New York and a Special Weather Statement has been issued for our region.
