High Wind Warning

Deep low pressure near Kingston tonight is expected to pass near Kemptvile and just north of Montreal in the next few hours. The central pressure was 985mb with this storm and falling and I currently show 987mb here at my home on L'Ile Perrot. Freezing rain is currently falling here, but expect that to briefly change to rain before tapering off to flurries. We had between 5 and 10cm of snow in Montreal today, that combined with the rain is making for very icy roads. Numerous cancellations and delays have been reported at both Trudeau and Ottawa International Airports. As the low pressure passes by Montreal around midnight, strong winds will develop out of the west. A look at observations across southern and eastern Ontario is showing winds gusting to close to 70km/h in Toronto and Kingston and 80km/h along the shoreline of Lake Erie. High wind warnings are in effect for the entire St. Lawrence Valley with winds expected between 50 and 80km/h. They will diminish to 30 to 50km/h on Wednesday. Temperatures are currently at -1C and will briefly go above freezing before dropping down to -10C by morning. Needless to say that combined with the strong winds and the ice and snow will create dangerous driving overnight and early Wednesday.
