Winter storm possible Friday

The likelihood of a big snow event on Friday is becoming a little clearer this evening. Low pressure over the southern plains is expected to track south of the lower lakes on Friday and lie near Boston by early Saturday. Snow will overspread southern Ontario and southern Quebec as well as New England by Friday morning and persist all day with blowing snow as well. The potential exists for more than 10cm. As of 8pm a Winter Storm Watch is in effect for New York and Vermont, along with a Special Weather Statement posted for Ontario and Quebec. I will update this potential winter storm by 6am tomorrow morning.
