Mixed precipitation today

The radar says it all at 8am this morning, with lots of frozen precipitation moving from south to north.

8am Update: Mixed precipitation continues across the region at 8am. It is so variable from one station to the next. Trudeau Airport has 0C with rain while to the east it is snowing in St. Hubert at 1C and just west on L'Ile Perrot it is -4C with freezing rain. Travel is slippery and slow and will be that way all day. I think the snow will eventually take over as the main precip type with 5-10cm in the city and 15-20cm north and west.

6am Update:
Montreal is now up to 1C with light wet snow, good news as snow is better than ice. Meanwhile it is very slippery in Ottawa at -6C with freezing rain. School buses have been cancelled all across Eastern Ontario, so it is a snow day for students.

Precipitation is rapidly spreading north and east into Montreal this morning, as low pressure moves from the Mississippi Valley into upstate New York. The track of the system will be very close to Montreal today with mostly freezing rain and rain from Montreal south and snow north and west of the city. About 25mm of precipitation will fall in various forms over the course of the day. Add to that gusty winds up to 50km/h and it should be an interesting weather day.

This morning the temperature at the airport in Montreal has risen rapidly from -4C to 0C with a southeast wind and light snow. It is -3C here on l'Ile Perrot. The temperature is -6C in Ottawa with light snow and above freezing at 2C in Kingston with rain. As you can see it is a very tricky forecast across the area. Freezing Rain Warnings are in effect for eastern Ontario and southern Quebec. Winter Weather Advisories are posted for northern New York and Vermont. Northwest of Montreal towards Ottawa and into the Gatineau Hills mostly snow will fall with 10-15cm expected.
