Winter returns to southern Quebec & Ontario

Cold weather will dominate the forecast for the rest of this week and well into the next one as arctic high pressure drives frigid air south. Environment Canada has posted a special weather statement for the province indicating very cold air and windchill values for the balance of the week. Temperatures this morning are hovering around -15C in southern Quebec, but a decent west wind is making it feel as cold as the minus 20's. It will be a very cold week with temperatures running 5-10 degrees below normal. We can also expect clouds and a few flurries as weak disturbances move across the region. The first of these today will give some light snow this evening and especially early Wednesday. A few centimetres may fall locally. More light snow is forecast for Thursday with another couple of centimetres. Temperatures will remain cold with low near -20C and daytime highs at best -10C for Montreal. At this time no big storms are on the horizon.
