There is a growing concensus on the system next week but unfortunately for the snow geese, the concensus is converging on a storm center track that follows Hwy. 401, give or take a few dozen kilometers. But first we likely get a dusting of snow on Saturday after which there will be a brief break in the action until about the wee hours of Monday morning. Given the current forecast track of the Monday system, the storm will start as snow for the morning, changing over to rain in the afternoon (there may be a brief episode of freezing rain in this transistion) and then a change back to snow in the evening/overnight as the storm center passes by.
If only this were a few weeks from now, it'd be a heck of a snow storm.
