A brief break from the cold in Montreal - snow on the way

A spectacular shot of waves crashing into the coast at Hampton Beach yesterday. US Highway 1A along the New Hampshire coast was closed in sections from flooding and severe ice buildup in the arctic cold. The Nor'Easter shut down Nova Scotia as well as parts of New England with 1-2 feet of wind driven snow and record cold. (Hampton Beach Official Facebook page photo)
After nearly 65 hours of below -18C (0F) weather we finally rose above that mark this morning at 8am here at my home on L'Ile Perrot. We are a relatively milder -14C currently. Still cold and damp but better with a mix of sun and cloud and perhaps a few flurries. We should warm to -12C today on a southwest flow ahead of a cold frontal boundary over the central Great Lakes. This front will draw a storm system up from Oklahoma along the lower Great Lakes and down the St. Lawrence Valley by Monday. Montreal will be on the line between snow and rain as we warm to above freezing by Monday morning. Best estimates at this time are for 10cm of snow for metro Montreal before a switch to freezing rain and perhaps rain. Ottawa should see more snow with up to 20cm. We may see warnings later today for a portion of Ontario and Quebec.

The high in Montreal Sunday will be -7C with 0C Monday. It all goes back to snow with a rapid freeze Monday afternoon as the cold front sweeps in. Some of the coldest air in the last 20 years waits behind that front but I think it will modify before it reaches Montreal.
