Nova Scotia·FORECAST

Kalin Mitchell says Nova Scotia will get 5 cm to 15 cm of snow

I've done some work on the snow expected tomorrow. As a re-cap this is being brought in by a centre of low pressure expected to develop near Cape Cod early tomorrow morning which will then move into the Gulf of St. Lawrence by Friday morning.

I've done some work on the snow expected Thursday. As a re-cap, this is being brought in by a centre of low pressure expected to develop near Cape Cod early Thursday morning which will then move into the Gulf of St. Lawrence by Friday morning.  

That track takes it directly through the Maritimes. It lacks the strength of the last winter storm but, as Peter Coade said earlier this morning, will produce some "shovelable" snow amounts.

While bands of lighter snow will precede the system overnight and Thursday morning, the steadiest will develop Thursday afternoon and into the evening.  

General snowfall amounts remain in the range of five to 15 centimetres across the Maritimes, but I've narrowed down a few areas that have the best chance of lower amounts and one area in New Brunswick that could see very localized amounts of close to 20 centimetres.  

Winds will be a bit gusty with this system but mostly in the range of 40 to 60 km/h. Localized blowing snow is possible.

The next more significant coastal low is set to arrive on Sunday. That will be a harder forecast as there will be a rain-snow line that could not only push through Nova Scotia but also across P.E.I. and southern New Brunswick. Those areas are set to see a "wintry mix" of snow mixing through ice pellets/freezing rain over to rain.  

The position of that line will greatly impact snowfall amounts. I'll be working on maps for that Thursday and Friday, but currently it looks like only areas Fredericton and north in New Brunswick will have a shot at 20-plus centimetres of snow. That's not to say that the system won't have major impacts on other areas of the Maritimes.

A good 20 to 40 millimetres of rain may fall across much of Nova Scotia and P.E.I. leading to concerns of localized flooding.

I know it's next to impossible for some areas, but if you can locate and clear drains and drainage systems around your property it would be a good idea to do so as we head into the weekend.

More updates to follow for that Sunday system.
