A strong cold front associated with low pressure over central Ontario is racing east this morning. heavy rain is falling along the front with 10-20mm expected in most regions of eastern Ontario and western Quebec. The front will be accompanied by very strong winds with gusts up to 70km/h possible. This mornig gusts are already over 50km/h in many places.
At 9am the front is crossing eastern Ontario southwest towards Sarnia. It is 8C in Windsor and only 0C in Sarnia. That gives you an indication of the rapid drop in temperature that occurs with the passage of the front. In eastern Ontario it is 7C in Kemptville and 10C in Cornwall. Montreal is currently at 5C. Look for temperatures to plummet to -5 to -10C by this evening with any rain changing over to light snow and ending rapidly. Any wet surfaces will freeze quickly, keep this in mind if you are travelling this afternoon in Ontario or tonight in Quebec.
