Local snowfall amounts near five centimetres are possible in the heaviest snow squalls by the time the snow squalls move out to the south over Lake Huron and Georgian Bay this evening.
At this point it appears that the most significant lake snow will fall during the day and this evening east and northeast of Lake Ontario (well north of Syracuse).
Within the lake effect snow band (s) snowfall accumulations of a foot or more will likely occur in the heaviest, most persistent snow during this 2 day stretch.
Travel will likely be hard with snow covered, slippery roads and low visibility in the aforementioned areas.
We are getting to the time of year that we talk about lake effect snow.
Thursday: A mix of clouds and sun in the morning followed by cloudy skies during the afternoon.
With scattered snow showers in the area today allow a few extra minutes for your commute. We won't rule out accumulations at this time, but the best chance of those right now look to be in central and southern in, which is a little different. However, the prevailing wind direction is primarily southwest.
In the extended period, we still see nothing spectacular until we get closer to the 18th and 19th. This is not a big snow accumulation event, but the chances of snow look better.
A storm system is responsible for starting the process of this pattern change. So, we will keep chances for accumulating snow with the eve4nt, but move it to Thursday instead of Wednesday. We see scattered little bits of action here and there, more nuisance than anything else but it adds up. The next chance for snow accumulations will be Friday afternoon and Friday night. This can bring liquid equivalent precipitation of up to half an inch to the state with 90% coverage. But...we will see how the system progresses. The northern half of the state sees better snow chances in our forecast this morning.
