I’m still very intrigued and, I’m not going to lie, a little concerned with the developing Nor’easter that will have us reaching for a shovel midweek next week.  But before we get bogged down with specifics regarding that one, you should be aware of an offshore low that will slide south of Nova Scotia late tomorrow.  Nailing down exact snowfall amounts is never easy, but it’s especially tricky when the low is offshore.

A dry slot, stretching from the Gaspe across to the Avalon Peninsula, will push down on the developing area of low pressure offshore.  This system is not going to come on land and that means there will not be any rain, just snow.   This will be a numbers game: should the low swing in and hug the coast we can expect more than 10 cm of snow across much of Nova Scotia and flurries for southern New Brunswick and PEI.  If the wedge of cold dry air remains strong enough, then we’re looking at 5 cm for the south shore to Halifax and 5-10 cm east to Louisbourg.

The system is not going to linger: the snow should start over the SW tip of Nova Scotia by about 2 pm and reach Cape Breton after sunset – 7 or 8 pm; lasting about 6 hours. 

The ridge of high pressure reaching eastward from the arctic high over the prairies will take over on Saturday with some sun but very cold temperatures for the weekend. 

The developing system that would reach us late Tuesday into Wednesday is still loaded with potential.  I haven’t seen anything what would make me change my thoughts on the storm …yet! 

I’ll have the very latest on both, tonight on CTV News at 5 and 6.
