Freezing Rain Warning

As I expected Environment Canada has posted a freezing rain warning for a wide area of southern Quebec including metro Montreal, as well as eastern Ontario. Low pressure is forecast to move from Illinois to upstate New York today, passing just south of Montreal. This track places us just north of the warm front, and in a favorable position for an extended period of freezing rain. Radar this morning is showing light snow moving into the region from the southwest, that will be followed by the steadier precipitation by the middle part of the day. Expect 2 to 10 mm of frozen precipitation, more than enough to make travel dangerous. Mild air will work as far north as the US border, as a matter of fact Montreal is -5C currently while Burlington, Vermont is already at the freezing point. For that reason expect just regular rain from the border region south. If your travel plans take you anywhere but straight south today, expect delays and icy roads. The precipitation will end this evening as a period of flurries. Temperatures today will remain near 0C in Montreal and Ottawa. Looking ahead we may have a little light snow on Thursday and again Sunday, but no major snow is in the forecast at this time, but perhaps just enough to whiten the ground.
