Arctic Chill

After yesterday's wind, snow and ice, temperatures are frigid this morning. I have -19C here on Ile Perrot with a windchill of -27C at 7am, Trudeau Airport is -18C with a windchill of -30C, Ottawa is -20C with a windchill of -29C. I walked the dog briefly (her request to end it early) and trust me it is cold out. Montreal ended up officially with about 5cm of snow at the airport and around 15mm of rain from the last storm. There were reports of as much as 10cm of snow off island and upwards of 25mm of rain. All in all it was a nasty little storm. Look for a windy and cold but sunny day today as high pressure crests over the region. Winds will remain gusty out of the northwest up to 50km/h, so windchill values will remain dangerously cold. A series of weak clipper type systems will affect southern Quebec and Ontario into New Years Day with periods of snow or light rain starting Friday and lasting into New Years Day. Amounts will be light but mixed precipitation will likely ice roads again. The biggest challenge once again will be determining the precipitation type as temperatures take the roller coaster ride back above freezing. It looks like more arctic air, possibly colder than this bunch will plunge back into the region to start the New Year by late Monday. Another period of snow and wind will accompany the cold.

Please drive safely and adjust your speed to mid-winter driving. There were numerous accidents in the region yesterday including another fatal one here in Montreal. It has been a deadly holiday season on Quebec roads. Wherever you are, slow down and allow your winter tires to do there job.
