Well I think after the cold and windy weekend we all felt like we were turning the corner this week into Spring. The sunshine has been slowly warming the temperatures, and today looks to be the best yet with warm sunshine and the mercury pushing close to 8C if not warmer in some locations. That is the good news, the bad news is it now looks like we could see a storm on Friday (we can call it the April Fools Day storm). This is a wee bit of a surprise to me, last I looked the system in question was expected to move well off the Atlantic Coast and out to sea. It now appears that this will not be the case, so much so that a Winter Storm Watch has been posted for most of northern New England for late Thursday and Friday.
What does all this mean for Ontario and Quebec? Well I think the storm will be far enough southeast as to not affect most of Ontario except maybe from Cornwall to the Quebec border. Montreal and southern Quebec are a different story, and the potential does exist for a significant wet snow event, especially across the Eastern Townships. Low pressure centered over Tennessee is expected to strengthen and move towards Cape Hatteras then northeast to Cape Cod. A cold rain and wet snow will overspread the region late Thursday from south to north and continue Friday. A chilly northeast and then northwest wind will occur with the system. Snowfall totals are always difficult with Spring systems as they rely heavily on time of day and temperature profile, but it looks like a good 10-25cm for New England and perhaps the same for southern Quebec. The storm will also affect eastern Quebec and Atlantic Canada into the weekend. Looking ahead to next week another system could threaten the area with rain and snow to start the week.
Look for an update later today after 6pm...SB
